Answer:
C. m ≥ 9
Step-by-step explanation:
7m -2 ≥ 61
7m ≥ 61+2
7m ≥ 63
m ≥ 63/7
m ≥ 9
First, lets convert them into multipliers:
The multiplier for a:
25% increase = 1.25
40% decrease = 0.6
40% increase = 1.4
Now to work out the overall percentage change, we just times all of the multipliers together, and convert it back to a percentage:
1.25 x 0.6 x 1.4 = 1.05
So the overall multiplier is 1.05
And a multiplier of 1.05 = a <u>5% increase</u>.
That means that the percentage change is + 5%

Answer:
The percentage change in shares from the start of 2013 to the end of 2015 is:
+ 5%

Note: if you haven't been taught multipliers - then ask and I'll try my best to explain!
X=y-2
2y=5x-17
Substituting for x into the second equation, we find
2y=5(y-2)-17
2y=5y-10-17
-3y=-27
y=9
So x=7
Thus, the two numbers are 7 and 9.
When you take any polynomial and subtract any other polynomial from it you always get a third polynomial that is the closure property
The expressions are not equivalent, even though Ella got the same result when she substituted zero for f. Then the correct option is C.
<h3>What is an equivalent expression?</h3>
The equivalent is the expressions that are in different forms but are equal to the same value.
Ella completed the following work to test the equivalence of two expressions.
First expression, Second expression
⇒ 2f + 2.6 ⇒ 3f + 2.6
⇒ 2(0) + 2.6 ⇒ 3 (0) + 2.6
⇒ 0 + 2.6 ⇒ 0 + 2.6.
⇒ 2.6 ⇒ 2.6
The expressions are not equivalent, even though Ella got the same result when she substituted zero for f.
Then the correct option is C.
