Answer:
The value of 
which makes the equation true.
Step-by-step explanation:
Given the equation
We have to find the value of r for which the equation must be true.
solving the equation
Multiply both sides by -11
Therefore, the value of which makes the equation true.
<u>VERIFICATION:</u>
Putting in the equation
∵
L.H.S = R.H.S
Therefore, the value of which makes the equation true.
Answer:
number 1 is c number 2 is b,c,e number 3 is b
Step-by-step explanation:
1: if you see something to the power you will always think of repeated multiplication off the bat. so you just multiply the coefficient by the amount of the exponent.
2: 1*1*1*1*1*1*1*1*1*1*1*1*1*1*1*1=1 no
2*2*2*2=16 yes
4*4=16 yes
8*8=64 no
16=16 yes
3: 3/4*3/4*3/4=27/64
hope this helps! have a nice day!

Answer:
Inequality Form:
r ≥ 7
Interval Notation:
[7, ∞)
Step-by-step explanation:
−1.3 ≥ 2.9 − 0.6r
Rewrite so r is on the left side of the inequality.
2.9 − 0.6r ≤ −1.3
Move all terms not containing r to the right side of the inequality.
Subtract 2.9 from both sides of the inequality.
−0.6r ≤ −1.3 − 2.9
Subtract 2.9 from −1.3.
−0.6r ≤ −4.2
Divide each term by −0.6 and simplify.
Divide each term in −0.6r ≤ −4.2 by −0.6. When multiplying or dividing both sides of an
inequality by a negative value, f lip the direction of the inequality sign.
−0.6r
/−0.6 ≥ −4.2
/−0.6
Cancel the common factor of −0.6.
−4.2
r ≥ ______
−0.6
Divide −4.2 by −0.6.
r ≥ 7
The result can be shown in multiple forms.
Inequality Form:
r ≥ 7
Interval Notation:
