Step-by-step explanation:

Check it mate, triangles must add up to 180 and the angles at the bottom are equal right? so we know the top angle is 74 so 180-74 = 106. ok so 106 / 2 = 53.

F(x)=-x^2+x f(x)=−x Find f(−1)

STALIN [3.7K]

Answer:

Step 1: Set x to -1 in the first equation

$f(x) = -x^2 + x$

$f(-1) = -(-1)^2 + (-1)$

$f(-1) = -(1) - 1$

$f(-1) = -1 - 1$

$f(-1) = -2$

Step 2: Set x to -1 in the second equation

$f(x) = -x$

$f(-1) = -(-1)$

$f(-1) = 1$

A particular rocket taking off from the earth surface uses fuel at a constant rate of 12.5 gallons per minute the rocket initial

faltersainse [42]

Answer:

$y=12.5x+225$

Step-by-step explanation:

Let

x ----> the number of minutes

y ----> the amount of fuel in gallons

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the unit rate or slope

b is the y-intercept or initial value

we have that

The unit rate or slope is equal to

$m=12.5\ \frac{gal}{min}$

$b=225\ gal$ ----> initial value (value of y when the value of x is equal to zero)

substitute

$y=12.5x+225$
