The missing coordinate r is 11.
Solution:
Given points are (–15, 1) and (–7, r).
Slope (m) = 
<u>To find the missing coordinate r:</u>
Slope formula:
Substitute the given values in the formula.
Do cross multiplication.
40 = 4r – 4
Add 4 on both side of the equation.
44 = 4r
Divide by 4 on both side of the equation.
11 = r
⇒ r = 11
Hence the missing coordinate r is 11.
(-1,x) you didnt say how many units up
5x + y = -13.....multiply by -3
4x + 3y = -17
-----------------
-15x - 3y = 39 (result of multiplying by -3)
4x + 3y = -17
-----------------add
-11x = 22
x = -22/11
x = -2
5x + y = -13
5(-2) + y = -13
-10 + y = -13
y = -13 + 10
y = -3
solution (-2,-3)
Answer:
1/4
Step-by-step explanation:
Since there is 4 colors and four rooms there is a 1/4 possibility that she paints the room green.
Answer:
2 x^ (3/2)
Step-by-step explanation:
(x^2+x^2)
----------------
x^1/2
Combine like terms
2x^2
-----------
x^1/2
When dividing exponents with the same base, we subtract
a^b/ a^c = a^ (b-c)
2 * (x^2/ x^1/2) = 2( x^(2-1/2)) = 2 * x^ (3/2)
