Answer:
x=140/-18
x=-7+7/9
Step-by-step explanation:
-5(4x-2)+2x+1=151
We move all terms to the left:
-5(4x-2)+2x+1-(151)=0
<em>We add all the numbers together, and all the variables</em>
2x-5(4x-2)-150=0
<em>We multiply parentheses</em>
2x-20x+10-150=0
<em>We add all the numbers together, and all the variables</em>
-18x-140=0
<em>We move all terms containing x to the left, all other terms to the right</em>
-18x=140
x=140/-18
x=-7+7/9
Answer:
First graph
Step-by-step explanation:
The y-intercept of f(x)=2(3)^x is found by letting x = 0: f(0) = 2(3)^0 = 2.
Thus, we can immediately eliminate the 2nd and 4th answer graphs.
Next, determine whether (1, 6) from the first graph satisfies f(x)=2(3)^x:
2(3)^1 = 2(3) = 6. Yes. So the first graph is the correct one.
Let d be number of drinks and b be number of buckets of chips
2d+b=11 so we can say b=11-2d
3d+2b=19 and using b from above in this we get:
3d+2(11-2d)=19
3d+22-4d=19 subtract 22 from both sides
-d=-3 divide both sides by -1
d=3, and from earlier b=11-2d so
b=11-6=5
So a bucket of chips cost $5 and a drink costs $3
1. B
Robin got C because she found the sum of students that didn't plan to go to the school play.
2.
Sixth graders
No: 48.1%
Seventh graders
Yes: 45.2%
Eighth graders:
Yes: 40%
No: 60%
Yes, because the higher the grade level, the less students that planned to go to the play. It was probably because the higher grade level students have more things planned and less time to do stuff.
