F(x) = 2/3x + 7...when x = -12 g(x) = 2x + 15....when x = -12
= 2/3(-12) + 7 = 2(-12) + 15
= -8 + 7 = -24 + 15
= -1 = -9
when x = -9
f(x) = 2/3(-9) + 7 g(x) = 2(-9) + 15
= -6 + 7 = -18 + 15
= 1 = -3
when x = -6
f(x) = 2/3(-6) + 7 g(x) = 2(-6) + 15
= -4 + 7 = -12 + 15
= 3 = 3
thats it......when x = -6, both functions have the same output of 3
Slope = (10 - 5)/(-9 + 15) = 5/6
y = mx + b where m = slope and b = y-intercept
b = y - mx
b = 5 - (5/6) (-15)
b = 5 +12.5
b = 17.5
Equation y = 5/6 x + 17.5
Y-intercept = 17.5
X-intercept when y = 0
So
5/6 x + 17.5 = 0
5/6 x = -17.5
x = (-17.5) (6/5)
x = -21
Answer
Y intercept (0, 17.5 )
X intercept (-21 , 0)
Answer: 150 students walk to school
Step-by-step explanation: 75%=0.75
200 multiplied by 0.75
200×0.75=150 students
Or
75%=3/4
3/4 of the children walk to school
3/4×200=3/4×200/1=150
Answer:
y = -5x + 30, 20th number is -70.
Step-by-step explanation:
All you have to do is look at how much the equation is growing by and what the starting number is for the equation. to find the 20th figure, you plug 20 in for x and get -70.
