Answer:
-13
Step-by-step explanation:
Plug in 10 as x into the function:
f(x) = -2x + 7
f(10) = -2(10) + 7
f(10) = -20 + 7
f(10) = -13
So, f(10) = -13
Okay let’s go through this together I’ll break it down.
2x+3/ x-2 = 38/12
Cross multiply
12(2x+3) = 38(x-2)
24x+36 = 38x-76
- 36= -36
—————————-
24x= 38x-112
-38x= -38x
———————-
-14x = -112
—————— divided
-14x = -14
X= 8
You need to make the fractions into improper fractions with the same denometer. 3 4/7 to an improper fraction is 25/7 and 3 1/4 is 13/4. Now get common denometers, in going to choose 28. 100/28 is the same as 25/7 and 91/28 is the same as 13/4. Now subtract 100/28 and 91/28 and you get 9/28. So you need to add 9/28 of a cup.
The answer is 24 square units because for this all you have to do is count how many squares are on the top. plz mark brainliest!!!!!!!!!!!!!!!
