Answer:
y= -3x+24
Step-by-step explanation:
First find the slope of the line
-x + 3y = -6
Add x to each side
3y = x-6
Divide by 3
3y/3 = 1/3 x -6/3
y = 1/3x -2
The slope is 1/3 since it is in the form y = mx+b where m is the slope
Perpendicular lines have slopes that multiply to -1
1/3 * m = -1
m = -1 * 3/1
m = -3
The slope of the perpendicular line is -3
Slope intercept form is
y = mx+b where m is the slope and b is the y interceot
y = -3x+b
We have a point ( 6,6)
6 = -3(6) +b
6 = -18+b
Add 18 to each side
6+18 = -18+b+18
24 = b
y= -3x+24
Answer:
y= -3x+24

12. Which line has an x-intercept of -1 and a
y-intercept of 1?
A. y = -x
B. x - y = 1
C. x - y = -1
D. x + y = 1
Answer:
#4
Step-by-step explanation:
1) The y intercept is 0.
2) Convert to slope-intercept form:
2x + 3y = 12
3y = -2x + 12
y = -2/3 x + 4
So the y-intercept is 4.
3) Write in point-slope form:
y + 4 = 2 (x - 1)
Now convert to slope-intercept form:
y + 4 = 2x - 2
y = 2x - 6
So the y-intercept is -6.
4) The y-intercept is 5.
So of the four lines, #4 has the largest y-intercept.
The line with an x-intercept of -1 and a y-intercept of 1 is C. x - y = -1
A linear equation is of the form:
y = mx + b
where y, x are variables, m is the slope of the line and b is the y intercept
Given the line x - y = -1, the x intercept is at y = 0, hence:
x - 0 = -1
x = -1
The y intercept is at x = 0, hence:
0 - y = -1
y = 1
The line with an x-intercept of -1 and a y-intercept of 1 is C. x - y = -1

what is the measure of angle MBT
Answer : The measure of angle MBT is 28°.
Step-by-step explanation :
As we see that the ∠NBM is equal to ∠MBT.
That means,
∠NBM = ∠MBT
Given:
∠NBM = (17x - 6)°
∠MBT = (5x + 18)°
According to question:
∠NBM = ∠MBT
(17x - 6)° = (5x + 18)°
17x - 5x = 18° + 6°
12x = 24°
x = 2°
So,
∠NBM = (17x - 6)° = [(17 × 2) - 6]° = 28°
∠MBT = (5x + 18)° = [(5 × 2) + 18]° = 28°
Hence, the measure of angle MBT is 28°.
Answer:
the answer is 28
Step-by-step explanation:
What is the value of y in the following system?
4x - 10y = -3
12x + 5y = 12
Y=3/5
First, set it up so they cancel. I recommend multiplying the second equation by 2, getting
[tex]4x-10y=-3[/tex]
[tex]24x+10y=24[/tex]
add them together, and you get
[tex]28x=21[/tex]
so
[tex]x=3/4[/tex]
then, you plug x into one of the equations (first because it's easier) and get
[tex]3-10y=-3[/tex]
so
[tex]-10y=-6[/tex]
and
[tex]y=3/5[/tex]

Kim's age is twice that of her sister. When you add Kim's age to her sister's age, you get 42. How old is each sister?
(a) Write an equation that represents the situation. Explain any variable used.
(b) Solve the equation from Part (a). Show your work. State your solution as a complete sentence.
Answer:
a: K = 2s
K + s = 42
b: 2s + s = 42
K = 28
s = 14
Step-by-step explanation:
1. Come up with equations based on the information given.
K = Kim
s = sister
Kim is twice of her sister -> K = 2s
When you add Kim's age to her sister's age, you get 42 -> K + s = 42
2. Substitue for K to find out the value of s
K = 2s
2s + s = 42
3. Solve for s
s = 42/3
s= 14
4. Solve for K
K = 2s
K = 2*14
K = 28

–6x2 - 235 = -48x + 11
Answer:
6(x-5)2+288
Step-by-step explanation:
6x2-60x+438 Factor out a 6 from the first 2 terms.
6(x2-10x )+438 Do (b/2)2 to find the c term. (-10/2)2 = 25
6(x2-10x+25)+438-150 Adding 25 inside the parenthesis is really like adding 6(25)=150 to that side of the equation. To keep the equation in balance, you have to subtract 150 from the other term. Simplify

Answer:
6x + 14
Step-by-step explanation:
Original Equation:
2x^3 + 1x^2 - 3x + 14
2x to the 3rd power is 8x
8x + 1x^2 - 3x + 14
1x to the 2nd power is 1x
8x + 1x - 3x + 14
8x + 1x = 9x
9x - 3x + 14
9x - 3x = 6x

I just need 8 and 9 pls help been stuck here forever
Answer:
8: C
9: D
10: C
11: D
Step-by-step explanation:
On number 8, the pattern is by starting from 3, and squaring it. Then you take that square and square it again. So 3 squared is 9, and then you square 9 which is 9 times 9 giving you 81. Then you square 81 giving you 6561.
9: Negative exponents work by flipping the number upside down, and then doing normal exponential work on the now denominator.
If the number is 5 to the power of -3, you are flipping 5 to 1/5 and then doing 5 to the power of 3 which is 5x5x5 giving you 125. Therefore the answer would be 1/125.
10 is the same thing as number 9 except backwards, so you flip 1/2^3 to 2^-3
11 is similar, except you have 3.471 times 1/10000
So you add 4 zeros in front of the 3.471 turning it into 0.0003471

Ethan played in two basketball games. He scored 4 fewer points in the second game than he scored in the first. He scored 12 points in the second game. How many points did he score in the first game?
9514 1404 393
Answer:
16 points
Step-by-step explanation:
You are given ...
second = first - 4
second = 12
Substituting the second equation into the first, we have ...
12 = first - 4
16 = first . . . . . . . . add 4 to both sides
Ethan scored 16 points in the first game.
Can anybody help me on this math question for number 3 and Find the measure of each interior angle of the regular polygon?
Answer:
the measure of each angle is 150.
Step-by-step explanation:
in order to find this you need to find the measure all the degrees which can be found with (n-2)x180
in this case this is (12-2) x 180
so you would get the total degrees in the inside is 1,800
then there are a total of 12 interior angles so divide 1,800 by 12 to get 150 for each interior angle (btw this is only possible since this is a regular polygon meaning that every one of the angles are the same )
