Answer:
The answer is No.
Step-by-step explanation:
The answer is no because an integer is any whole number that isn't a fraction. So this can be positive and still be an integer.
<span>3x – 15y = 60
y-intercept x = 0</span>
3(0)– 15y = 60
-15y = 60
y = -4
x-intercept y = 0
3x– 15(0) = 60
3x = 60
x =20
answer :
<span>C. x-intercept: 20; y-intercept: –4</span>
Answer:
x = 2
Step-by-step explanation:
f(x) = x + 8
f(x) = 10
10 = x + 8
minus 8 from the both sides
10 - 8 = x
2 = x
x = 2
Answer:
The gradient of the line joining the points and is .
Step-by-step explanation:
The gradient of the line joining two distinct point on a plane is represented by the slope of a secant line (), that is:
(1)
If we know that and , then the gradient of the line is:
The gradient of the line joining the points and is .
Answer:
Step-by-step explanation:
Given function is,
f(x) = -8x² + 4
Step to find the inverse of the function,
Step 1
Write the function in the form of an equation,
y = -8x² + 4
Step 2
Interchange the variables 'x' and 'y',
x = -8y² + 4
Step 3
Solve the equation for y,
x = -8y² + 4
x - 4 = -8y²
-x + 4 = 8y²
y² =
Therefore, inverse of the function f(x) will be,
