Answer: 33/2
Step-by-step explanation:
3x2+2x-20=2x2+15
6+2x-20=4+15
2x-14=19
2x=19+14
2x=33
x=33/2
A. y = -5/4x = -5/9
B. y = -4x = 9
C. y = 5/4x + 9/4
D. y = 4/5x - 9/5
f(x)=-3(b)^x-5
f(x)=5(b)^x-1
f(x)=-5(b)^x+10
f(x)=2(b)^x+5
Answer:
Step-by-step explanation:
we know that
The y-intercept is the value of y when the value of x is equal to zero
Verify each case
case 1) we have
so
For x=0
therefore
The function has a y-intercept of (0,5)
case 2) we have
so
For x=0
therefore
The function does not have a y-intercept of (0,5)
case 3) we have
so
For x=0
therefore
The function does not have a y-intercept of (0,5)
case 4) we have
so
For x=0
therefore
The function has a y-intercept of (0,5)
case 5) we have
so
For x=0
therefore
The function does not have a y-intercept of (0,5)
