-7x = 21 (Subtract 6 from both sides)
x = -3 (Divide -7 from both sides)
What is an equation of the line that passes through the point (8, 2) and is parallel to
the line x + 4y = 28?
Answer:
x+4y is not change because it's parallel what changes is the result 8 + 4 × 2 = 16 so the equation is x + 4y = 16
An equation of the line that passes through the point (8, 2) and is parallel to the line x + 4y = 28 is;
⇒ x + 4y = 16
What is Equation of line?
The equation of line with slope 'm' and y - intercept at point 'b' is given as;
⇒ y = mx + b
Given that;
The point is = (8 , 2)
The line is x + 4y = 28
Since, Slope of line to its parallel line is same.
Hence, We find the slope of given equation of line as;
x + 4y = 28
After solving for y;
y = -1/4 x + 7
Compare with y = mx + b we get;
Slope (m) = -1/4
Thus, Equation of the line that passes through the point (8, 2) and is parallel to the line x + 4y = 28 is;
y - 2 = -1/4 (x - 8)
4(y - 2) = - (x - 8)
4y - 8 = -x + 8
x + 4y = 16
So, An equation of the line that passes through the point (8, 2) and is parallel to the line x + 4y = 28 is;
⇒ x + 4y = 16

If josiah skateboards from his house to school 4 miles away. It takes him 20 minutes.
If josiahs speed, in miles per minute, is constant, what is the constant of proportionality?
The constant of proportionality is 0.2
The constant of proportionality for Josiah's speed is 0.2 miles per minute.
To find the constant of proportionality, we can use the formula:
constant of proportionality = distance / time
In this case, we have the distance Josiah skateboards from his house to school is 4 miles, and it takes him 20 minutes.
So, the constant of proportionality is:
4 miles / 20 minutes = 0.2 miles/minute
Therefore, the constant of proportionality for Josiah's speed is 0.2 miles per minute. This means that he skateboards at a constant rate of 0.2 miles per minute from his house to school.

Answer:
x= -3, x=-5
Step-by-step explanation:
Answer:
x = -3 or -5
Step-by-step explanation:
This is a quadratic equation, meaning that the solutions (x-values) will occur when the parabola intersects the x-axis
For now, all you have to do is isolate each mini expression, because you can divide each side by either parenthesis (since it's multiplication)
(x+5)(x+3) = 0 (x+5)(x+3) = 0
divide by (x+5) divide by (x+3)
x+3 = 0 x+5 = 0
subtract 3 subtract 5
x = -3 x = -5
Keep in mind that the parabola intersects the axis at BOTH (-3, 0) and (-5, 0)
Therefore, both answers (must be together unless question says otherwise) can be the value of x
x = -3 OR -5

5(x+3)−5x
Thanks
Answer:
15
Step-by-step explanation:
First, you must distribute 5 to (x + 3)
5(x + 3) - 5x
5x + 15 - 5x
5x - 5x +15
(You can typically say 0x + 15, as a representation to show there are no more x values, but it is bet not to show any if there are none left)
(5x - 5x will cancel out, leaving only 15)
= 15

On a keyboard you would type sqrt(41)
===========================================

[tex]\text{point L} = (x_1, y_1) = (2,-1)\\\\\text{point N} = (x_2, y_2) = (7,-5)\\\\[/tex]
[tex]d = \text{distance from L to N}\\\\d = \sqrt{ (x_1-x_2)^2 + (y_1-y_2)^2 } \ \text{ ... distance formula}\\\\d = \sqrt{ (2-7)^2 + (-1-(-5))^2 }\\\\d = \sqrt{ (2-7)^2 + (-1+5)^2 }\\\\d = \sqrt{ (-5)^2 + (4)^2 }\\\\d = \sqrt{ 25 + 16 }\\\\d = \sqrt{ 41 }\\\\[/tex]
----------
A slight alternative is to plot the point M(2,-5) to form right triangle LMN. The 90 degree angle is at point M.
The legs are of length LM = 4 and MN = 5, which are found by subtracting the x coordinates together and the y coordinates together (or you can count the spaces). From there, use the Pythagorean theorem to get the hypotenuse LN.
The distance formula is an altered version of the Pythagorean theorem.
Answer:
The distance between the two points provided is: [tex]\sqrt{41}[/tex]
Step-by-step explanation:
First thing is to evaluate what the distance formula is:
d = [tex]\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2} }[/tex]
Then substitute the points provided:
d = [tex]\sqrt{(7-2)^{2}+(-5-(-1)^{2} }[/tex]
(The double negative between -5 and -1 will make the -1 a positive 1). (1)
d = [tex]\sqrt{(5)^{2}+(6)^{2} }[/tex]
Now the exponents:
d = [tex]\sqrt{25+36}[/tex]
Second to last, you must add:
d = [tex]\sqrt{41}[/tex]
If needed ± should be added in front of the radical.
The points are the same as the ones that were given.

6(10)+3(10)-21
60+30-21
90-21
69
Answer: (7.) the answer is 69
Step-by-step explanation:
The best way to remember this is PEMDAS ("Please Excuse My Dear Aunt Sally)
Parenthesis, Exponent , Multiplication, Division, Addition, Subtraction (this is the order that you should work your problem)
6x+3(x-7) lets see where there is a parenthesis first (x-7), we're going to plug in 10 where x is listed >> (10-7)= 3
The problem now reads 6x+3(3)
We do not have exponents, so we move to see if there is multiplication
6x>> we're going to replace x with 10 to read 6*10 = 60
The other multiplication is 3(3) which = 9
your problem now reads : 60+9
There are no division so we move to Addition
60+9= 69
There are no subtractions so you are now done with your problem and left with the answer 69

The standard form of a linear equation is
Ax+By=C,A,B≠0Ax+By=C,A,B≠0
Before you can graph a linear equation in its standard form you first have to solve the equation for y.

The given points in the coordinate plane that lie on the graph of the linear equation 4x - y = 3.
For (-1,-7)

3=3
So the point (-1, -7) lie on the line.
(0,3)
4(0)-3=3
-3=3
the point (0,3) does not lie on the line.
For point (3/4, 0)
4(3/4)-0=3
3=3
the point (3/4,0) lie on the line.
For point (1,1)
4-1=3
3=3
The point (1,1) lie on the line.
For point (2,5)
8-5=3
3=3
The point (2,5) lie on the line.
For point (4,-1)
16+1=3
17=3
For point (4,-1) does not lie on the line.

Find the 63rd term of the arithmetic sequence 2,9,16
Answer:
a₆₃ = 436Step-by-step explanation:
[tex]a_1=2\\a_2=9\\d=a_2-a_1=7\\\\a_n=a_1+d(n-1)\\\\a_{63}=2+7(63-1)=2+7(62)=2+434=436[/tex]
The 63rd term of the given arithmetic progression is 436.
What is an Arithmetic progression?
An arithmetic progression is a sequence of numbers such that the difference between the consecutive terms is constant. A sequence -
a₁ , a₂, a₃ , a₄ ...... aₙ
will be an arithmetic progression if -
a₂ - a₁ = a₃ - a₂ = a₄ - a₃ = d (constant) is called common difference of A.P. and a₁ = 'a' as the first term.
Given is the following sequence -
2, 9, 16, ..... nth term
First term [a] = 2
common difference [d] = 9 - 2 = 7
We can calculate the nth term of an A.P. using the formula -
a[n] = a + (n - 1)d
a[63] = a + (63 - 1) d
a[63] = 2 + 62 x 7
a[63] = 2 + 434
a[63] = 436
Therefore, the 63rd term of the given arithmetic progression is 436.

One triangle has angles that measures 45 degrees and 83 degrees. Another triangle has angles that measure 45 degrees and 42 degrees Are the triangles similar? How do you know?
Answer:
The two triangles are not similar
Step-by-step explanation:
Similar triangles have equal corresponding angles and proportion sides
Ex: If Δ ABC is similar to ΔXYZ, then
m∠A = m∠X, m∠B = m∠Y, m∠C = m∠Z[tex]\frac{AB}{XY}=\frac{BC}{YZ}=\frac{AC}{XZ}[/tex]In the given question
∵ One triangle has angles that measure 45° and 83°
→ Find the measure of the 3rd angle
∵ The sum of the measures of the angles of a triangle is 180°
∴ The measure of the 3rd angle = 180° - 45° - 83°
∴ The measure of the 3rd angle = 52°
∴ The measures of the angles of this triangle are 45°, 83°, 52°
∵ Another triangle has angles that measure 45° and 42°
→ Find the measure of the 3rd angle
∴ The measure of the 3rd angle = 180° - 45° - 42°
∴ The measure of the 3rd angle = 93°
∴ The measures of the angles of this triangle are 45°, 93°, 42°
∵ The two triangles have different measures of 2 angles
→ That means their corresponding angles are not equal
∴ The two triangles are not similar
