The answer is nonlinear. It goes in a sharp downward curve, whereas a linear function is a straight line.
Answer:
x=4.63
Step-by-step explanation:
Area = (1/2) (base) (height)
20 = (1/2) (x+4) (x)
40 = x²+4x
x²+4x-40=0
Put in quadratic equation:
x=
x=
x=4.63324958071 or x=-8.63324958071
Since x can't be negative in this case we take our answer to be 4.63324958071, which rounds to 4.63
Answer:
f(-3) = -3
Step-by-step explanation:
Step 1: f(x) means "f of x" and f(-3) means "f of -3", so you have to replace all the "x" letters in the function with the value -3.

Step 2: Apply the exponents. <em>Make sure you remember to put in the -3 and not just 3.</em>

Step 3: Use BEDMAS rules to complete the calculation.


Therefore the answer is f(-3) = -3.
Answer:
C
Step-by-step explanation:
<u>Equation A</u>
16x - 7 = 11x - 32
(16x - 7) - 11x = (11x - 32) -11x
5x - 7 = -32
(5x - 7) + 7 = (-32) + 7
5x = -25
(5x)/5 = (-25)/5
x = -5
<u>Equation B</u>
-4x - 10 = 2x + 20
(-4x - 10) - 2x = (2x + 20) - 2x
-6x - 10 = 20
(-6x - 10) + 10 = (20) + 10
-6x = 30
(-6x)/-6 = (30)/-6
x = -5
Both Equation A and Equation B have a solution of -5.
Answer:
-16
Step-by-step explanation:
distribute the 4: 4x-8=-72
add 8 to both sides: 4x=-64
divide by 4: x+-16
