Write an equation in slope-intercept form for the line that satisfies the following condition.
passes through (29,8), perpendicular to the graph of y= 5x +17.
Select one:
a. y = 385x + 1
b.y = -132 +385
c. Y = 12 +385
d.y= -132 + (-13)
Answer:
y = - x + 69
Step-by-step explanation:
Given the following :
Point on graph : (29, 8)
Equation of line ; y= 5x +17.
From the equation slope of line = 5
Intercept = 17
Slope of perpendicular line = - 1/5 ( negative reciprocal)
Using the equation :
y - y1 = m(x - x1)
From the Point given:
x1 = 29, y1 = 8
y - 8 = (- 1/5)(x - 29)
y - 8 = -1/5x + 29/5
y = -1/5x + 29/5 + 8
Multiply through by 5
y = - x + 29 +40
y = - x + 69

The other measurement has to be 120 degrees. In other words, the two angles have to add up to 180 degrees. The method for that is same side interior.
Step-by-step explanation:
In same side interior angles, the sum of the two angles has to be 180 degrees. So we know that one of the angles is 60 degrees so we do 180-60=120.

What is the graph of the solution to the following compound inequality? –6x – 1 < –25 or 3x + 4 ≤ –5
Answer:
[tex]x>4[/tex] or [tex]x \leq -3[/tex]
Step-by-step explanation:
Given :[tex]-6x -1 < -25[/tex] or[tex]3x + 4 \leq -5[/tex]
Solving first inequality :
[tex]-6x-1<-25[/tex]
Add 1 to both sides
[tex]\Rightarrow -6x-1+1<-25+1\\\Rightarrow -6x<-24\\\Rightarrow 6x>24[/tex]
Divide both sides by 6
[tex]\Rightarrow \frac{6}{6}x>\frac{24}{6}\\\Rightarrow x>4[/tex]
Solving second inequality:
[tex]3x + 4 \leq -5[/tex]
Subtract 4 from both sides
[tex]\Rightarrow 3x+4-4 \leq -5-4\\\Rightarrow 3x \leq -9[/tex]
Divide both sides by 3
[tex]\Rightarrow \frac{3}{3}x \leq \frac{-9}{3}[/tex]
[tex]\Rightarrow x \leq -3[/tex]
So, [tex]x>4[/tex] or [tex]x \leq -3[/tex]

What properties must a quadrilateral possess in order for the quadrilateral to be classified as a.. trapezoid isosceles trapezoid
Answer:
Step-by-step explanation:
The typical isosceles trapezoid will have a uniform width, measured vertically, but two ends that are not square (not perpendicular to the x-axis. The two sloping ends are congruent (their slopes have exactly the same slope.
The same could be said of an isosceles trapezoid that is vertical; the sloping ends have the same slope.
Answer:
2 parallel sides
2 non-parallel, congruent sides
Step-by-step explanation:
As any other quadrilateral, an isosceles trapezoid has 4 sides. 2 sides must be parallel. The other two sides cannot be parallel but must be congruent.
Which of the following cross sections cannot be produced by slicing a right rectangular prism? A. pentagon B. circle C. rectangle D. trapezoid
Answer:
The answer is option B.
Step-by-step explanation:
Since it's a rectangular prism slicing will produce either a rectangle or trapezoid and not or a circle since it's round
Hope this helps you
Answer: B. Circle
Step-by-step explanation:
Since the base is a rectangle and the faces are rectangular, there is no way to slice the prism to get a a circle.
The trapezoid ? Maybe. A diagonal slice starting on a corner will create a quadrilateral with uneven sides.
Pentagon? Imagine starting on the top near a corner-- but not on the corner-- with a diagonal line, slicing down towards the opposite corner. You should be able to get an irregular pentagon.
A rectangle is easy!
No circles!
Enjoy! I hope this helps you.
A company is building a new park in the shape of a circle with a 25 ft diameter. Portions of the new park will be covered with grass. A diagram of the park is given below, with the shaded region representing the areas that will be covered in grass. Use 3.14 for. Note: image is not drawn to scale. The area of the regions covered by grass is approximately sq ft.
Answer: The area of the regions covered by grass is approximately 313.375 sq ft.
Step-by-step explanation:
Given: A company is building a new park in the shape of a circle with a 25 ft diameter.
Then radius = [tex]\dfrac{25}{2}=12.5\ ft[/tex]
Required area = Area of circle - Area of rectangle + Area of triangle
Formula: Area of circle = [tex]\pi r^2[/tex]
Area of rectangle = length x width
Area of triangle = 0.5 x base x height
Area of circle = [tex](3.14)(12.5)^2=490.625\ \text{ft}^2[/tex]
Area of rectangle = 20 ft x 10ft = 200 ft²
Area of triangle = 0.5 x 7 x 6.5 = 22.75 ft²
Required area = 490.625 -200+22.75 = 313.375 ft²
Hence, The area of the regions covered by grass is approximately 313.375 sq ft.

In the circle below, O is the center and mĞ= 128° What is the measure of angle HIG?
Answer:
26 degrees.
Step-by-step explanation:
From the figure it is clear that HI is the diameter and [tex]acr(GI)=128^{\circ}[/tex]. So,
[tex]\angle GOI=128^{\circ}[/tex]
[tex]\angle GOI+\angle GOH=180^{\circ}[/tex] (linear pair)
[tex]128^{\circ}+\angle GOH=180^{\circ}[/tex]
[tex]\angle GOH=180^{\circ}-128^{\circ}[/tex]
[tex]\angle GOH=52^{\circ}[/tex]
Using central angle theorem of a circle, we get
[tex]\angle HIG=\dfrac{\angle GOH}{2}[/tex]
[tex]\angle HIG=\dfrac{52^{\circ}}{2}[/tex]
[tex]\angle HIG=26^{\circ}[/tex]
Therefore, the measure of angle HIG is 26 degrees.

Answer:
Let's say someone is selling lemonade at a lemonade stand. The more cups of lemonade this person sells, the more money they get. If 1 cup= $1, then he would get $2 for 2 cups.
Step-by-step explanation:
The price of the lemonade cup and the lemonade cup are a constant of proportionality. They are proportional to each other. The more lemonade you sell, the more money you get.
The graph would be a straight diagonal line. The y would be the money, and the x would be the amount of lemonade sold. Since they are the same and proportional, they would go in a straight line.

Brooke solved the equation below: 6r = 72 6r − 6 = 72 − 6 r = 66 Is Brooke’s solution correct? If the solution is incorrect, explain why it is incorrect and show the correct steps to solve the equation.
Answer:
see below
Step-by-step explanation:
6r = 72
We need to divide each side by 6, not subtract 6 from each side
6r/6 = 72/6
r = 12
Answer:
Brooke's solution is incorrect
Divide both sides by 6
r=12
Step-by-step explanation:
The equation is:
6r=72
Brooke solved the equation like so:
6r-6=72-6
r=66
Brooke's solution is incorrect. She subtracted 6 from both sides of the equation.
Here is how the equation should be solved:
6r=72
We want to solve for r, so we have to get r by itself. 6 and r are being multiplied (6*r=6r). The inverse of multiplication is division, so we must divide both sides by 6 (not subtract 6 from both sides).
6r/6=72/6
r=72/6
r=12
Brooke's solution is incorrect. She subtracted 6 instead of dividing by 6. The correct solution is r=12.

Answer:
( x + y )² = 32
Step-by-step explanation:
So far, I can tell that your calculations are incorrect. ( x + y )² is indeed x² + 2xy + y², which you can prove right by expanding the expression ( x + y )( x + y ). You simply swapped the positioning in this second step, and decided that the addition of x² + y² is x²y², but that is incorrect. You can't combine the two terms unless you multiply the two.
We should just be left with the expanded expression x² + y² + 2xy. Given that x² + y² = 17, and xy = 7.5, let's substitute and solve for the value of the expression.
17 + 2( 7.5 ) = 17 + 15 = 32,
( x + y )² = 32

Step-by-step explanation:
for the first one, you do 6-1=5 and then times that by 2 and then simplify that to get -7. for the second one, you do [tex]2^{3}[/tex] which is 8+4=12, and divide 24 by that to get 2 and minus nine to get -7. for the 3rd one, you do [tex]4^{2}[/tex]+9 first (16+9)= 25, and subtract 39 from that to get 14, then do 4-5=-1 *2=-2, which gets you -7. for 4 , you do 81-25= 56 over 10+8-11=7 which gets you 8. for 5, you do 36-20=16 in parentheses first and then divide 48 by that to get 3 and subtract that to get 8. last, for 6, you do 22-14 to get you 8
One number is seven less than a second number. Five times the first is 2 more than 6 times the second. Find the numbers. The value of the first number is _____.
Answer:
[tex]\Large \boxed{\sf \ \ 40 \ \ }[/tex]
Step-by-step explanation:
Hello,
Let's not a and b the two numbers.
One number is seven less than a second number.
(1) b = a - 7
Five times the first is 2 more than 6 times the second.
(2) 5a = 2 + 6b
(2)+5*(1) gives
5a + 5b = 2 + 6b + 5a - 35
b = 35 - 2 = 33
a = 40
The value of the first number is [tex]\large \boxed{\sf \ \ 40 \ \ }[/tex]

How many solutions does this system have? 2 x - 3 y = 10. -4 x + 6 y = - 20.
A) One
B) Two
C) An infinite number
D) No solution
Answer: The correct answer is: [D]: " No solution " .
______________________________________
Step-by-step explanation:
We are given the following system of equations:
2x − 3y = 10 ;
-4x + 6y = -20 ;
_______________________________________
Let us take the second equation:
-4x + 6y = -20 ;
and multiply each side by "-1 " ; to get rid of the "negative numbers" ; and to rewrite the equation without the "negative numbers" :
- 1 * { - 4x + 6y } = -1 * (-20} ;
to get:
4x − 6y = -20 ;
Now, let us simply this equation further; by divide each side of the equation by "2" ;
(4x − 6y) / 2 = (-20) / 2 ;
→ [ (4x) / 2 ] − [ (6y) / 2 ] = -10 ;
to get: 2x − 3y = -10 ;
Then we have: 2x − 3y = 10 ;
Note: 10 ≠ -10 .
_______________________________________
So the answer is: [D]: " No solution."
