the first one ((x+8, y+2), r x-axis)
LET X= ADDITIONAL AMOUNT
<u>EQAUTION=</u> 5+2x=17
-5 -5
__________
2x=12
_______
2 2
X=6 IS THE ANSWER. HOPE THIS HELPS!!!!!
If the function is: f(x) = 4^x - 8
D = {XeR}
R = {YeR|Y≥0}
if the function is: <span>f(x)=4^(x-8)
</span>D = {XeR}
R = {YeR|Y≥ -8}
Answer:
Numbers of students at a primary school before= 240
Number of increased students =42
Again,
Increased number of students in percent(%)= 42/240×100%= 17.5%
Therefore 17.5% students are increased this year.
-7 * 12 = -84
but
-7 + 12 = 5
