Answer:
-220
Step-by-step explanation:
Answer:
y=2x-1
Step-by-step explanation:
straight line equation
y=mx + c
find gradient(m) first,use formula;
m=3-7/2-4
m= -4/-2
m=2
use one the coordinates
(2,3)
3=2(2)+c
3=4+c
c=3-4
c = -1
y = 2x - 1
They didn’t distribute the -1 (which is the “-”) correctly into the numbers in the parentheses. After distributing correctly, step 1 should be
8a+3+5a-2a
Hope this helps :)
Answer:
2x-5
Step-by-step explanation:
f(g(x) means stick g(x) into f(x) in place of x
f(x) = 2x+1
f(g(x) ) = 2(g(x)) +1
and we know that g(x) = x-3
so replace g(x) with x-3
f(g(x) ) = 2(x-3) +1
Distribute
f(g(x)) = 2x-6+1
= 2x-5
Answer: 480
Step-by-step explanation: I want to say take 60 and 8 and times them together which will give you 480. but then again if you take 60 and divide it by 8 you get 7.5 so if the answer is not 480 then it has to be 7.5.
Hope this helps :)
