Step-by-step explanation:
m1.m2= -1
(4y = -2x -9)= (y = -1x/2 -9/4)
-1/2.m2= -1
m2 = 2
formula = y - y1 = m2 ( x - x1)
y - 10 = 2 ( x - (-7))
y - 10 = 2x + 14
y = 2x + 24
Answer:
Step-by-step explanation:
Did you mean percent if you did it’s 2
Answer
x=-2 and y=-3
Step-by-step explanation:
Step: Solvey=5x+7for y:
Step: Substitute5x+7 for y in 3x+y=−9:
3x+y=−9
3x+5x+7=−9
8x+7=−9(Simplify both sides of the equation)
8x+7+−7=−9+−7(Add -7 to both sides)
8x=−16
8x/8=−16/8
(Divide both sides by 8)
x=−2
Step: Substitute−2 for x in y=5x+7:
y=5x+7
y=(5)(−2)+7
y=−3(Simplify both sides of the equation)
Answer:
Step-by-step explanation:
use y = mx + b
slope(m) = 
y-intercept(b) = 3
so,
Answer:
Range is [0 , 7] for g(x)
Step-by-step explanation:
The range of f(x) is [0 , 1.75]
The range of g(x) is 4 times
4*0 = 0
4* 1.75 =7
Range is [0 , 7] for g(x)
