So I’ll do question 3. So normally you see f(x)= something plus x (something like that) you see it as a function of x.
So that notation of f(-1) means the function of -1. Which means you need to sub in -1 for x.
f(x)=-5x+5
f(-1)=-5(-1)+5
Negative times a negative is a positive
f(-1)=5+5
f(-1)=10
The original number would be 48. 12 multiplied by 4 is 48, and if you add a three to that you will get 51.
Hope this helped :)
Answer:
B. 3/4
Step-by-step explanation:
5/8 Get a common denominator of 24
5/8 *3/3 = 15/24
A. 12/24 this is less than
B. 3/4 *6/6 = 18/24 greater than
C. 15/24 same value so equal to
D.4/12 * 2/ = 8/24 less than
4 packages, because 24/12=2, 8/2=4 packages.
To find the answer we can use the angles sum of triangle which is 180° to find ∠z by deducting the other two angles from 180°:
180°-53°-90°
=37°
Therefore ∠z=37°.
Hope it helps!
