Hi! So I got :
-3 —>20
-2 —>13
-1 —>8
0 —>5
1 —>4
2 —>5
3 —>8
I’m sorry if any of these are wrong but In order to find the answers I used the “graphing quadratics” one (don’t know the name so sorry) but yeah first I found the axis of symmetry which was 1 and from there I built a chart and substituted. Again, I didn’t see some answer choices above in the image so sorry if there wrong, but yeah I hope this helped! (This is from algebra 1 by the way)
Step-by-step explanation:
125cm = 1.25m.
2m : 1.25m = 8:5
Answer: 2.75N = 80
Step-by-step explanation:
Let the the number of times that Ben can ride the train each month be represented by N.
Since Ben rides the train to work he spends $2.75 per ride and his monthly budget for riding the train is $80, this will be represented in an equation as:
2.75N = 80
N = 80/2.75
N = 29 times
12(2a-3)=-4a+5
Remember to follow PEMDAS. Note the equal sign, what you do to one side, you do to the other.
First, distribute 12 to all terms within the parenthesis
12(2a) = 24a
12(-3) = -36
24a - 36 = -4a + 5
Add 4a to both sides, and add 36 to both sides
24a (+4a) - 36 (+36) = -4a (+4a) + 5 (+36)
24a + 4a = 5 + 36
Simplify
28a = 41
Isolate the a. Divide 28 from both sides
28a/28 = 41/28
a = 41/28
Simplify a
a = 1.46 (simplified)
hope this helps
Hopefully this is what you are looking for.
5(q^2-r)+8(3q+2r)
Does this look like what you are currently doing?
5q^2-5r+24q+16r
5q^2+24q+11r
