Answer:
Step-by-step explanation:
First let's re-write the equation:
f(x) = 3x² - 5x + 4
If f(-2). then we can re-write the equation as:
f(-2) = 3(-2)² - 5(-2) + 4
We must solve for exponent first: (-2)² = 4
f(-2) = 3(4) - 5(-2) + 4
Then solve for multiplication:
f(-2) = 12 + 10 + 4
Finally addition:
f(-2) = 26
that means that in a function, if X = -2, then F is equal to 26
Answer:
0
Step-by-step explanation:
-6x+4=-6x+4
0x=0
X=0
To solve for the radius of the Earth in centimetres, we
know the following information:
1 km = 1000 m
1 m = 100 cm
Therefore,
radius = 6,380 km * (1000 m / km) * (100 cm / m)
<span>radius = 638 x 10^6 cm</span>
Supplementary angles have a degree measure of 180, so they look like a straight line.
Your answers are 4 and 3, 4 and 5, and 3 and 6.
