F(x)=-x^2+x<br> f(x)=−x <br> Find f(−1)

STALIN [3.7K]

Answer:

<u>Step 1: Set x to -1 in the first equation </u>

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

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

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

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

$f(-1) = -2$

<u>Step 2: Set x to -1 in the second equation </u>

$f(x) = -x$

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

$f(-1) = 1$

Two angles are supplementary. The measure of one angle is 54 more than the measure of the other angle. What is the measure of th

il63 [147K]

Answer:

bigger angle is 117°

Step-by-step explanation:

x+x+54= 180 (when two angles are complementary it means that their sum is 180 degrees)

2x+54=180

2x= 180-54

2x=128

x=126/2

x= 63

x1= smaller angle

x1= 63

x2= bigger angle

x2= 63+54

x2=117
