I'm not sure if that is supposed to be 7 or -7
If it's -7:
1<2n-5<-7
+5 +5 +5 Add 5 to all parts of the inequality get 2n by itself
6<2n<-2
/2 /2 /2 Divide all parts by 2 to isolate the variable
3
Answer:
The correct answer is D. 10.
Step-by-step explanation:
If Brandy earns 2 stars for every goal, and she scored 8 goals, then we need to multiply 8 by 2.
8 x 2 = 16
She looses 1/2 a star for every miss, and she missed the goal 12 times. Therefore, we need to multiply 1/2 by 12.
12 x 1/2 = 6
Therefore, Brandy lost 6 stars.
Now, we need to subtract the amount of stars Brandy earned by the amount that she lost.
16 - 6 = 10
Therefore, the correct answer is D. 10.
Hope this helps! :D
The exponential function is defined as y = a(1+r)^x, where "a" represents the original account and "r" the rate of growth or decay.
Then we have the following:
1) 22% grow
y = a( 1 + 22%/100 )^x = a(1.22)^x
So the solution is: 124(1.22)^x
2) 12% decay
y = a( 1 - 12%/100 )^x = a(0.88)^x
So the solution is: y = f(x) = 44(0.88)^x
3) 20% decay
y = a( 1 - 20%/100 )^x = a(0.8)^x
So the solution is: f(x) = 22(0.8)
4) 12% Groth
y = a( 1 + 12%/100 )^x = a(1.12)^x
So the solution is: f(x) = 42(1.12)^x
Answer:
18 = m
Step-by-step explanation:
2=m/2-7
Add 7 to each side
2+7=m/2 - 7+7
9 = m/2
Multiply each side by 2
9*2 = m/2 * 2
18 = m
So we have -23 degrees to start
Then add 5 to it
It becomes -23+5=-18
Now subtract 7 from that so -18-7=-25 degrees
Hope this helps
