Answer:

It would be D

because if you did

9x 30 it would be 270$

7 x 30 it would be 210$

5 x 30 it would be 150$

2 x 30 it would be 60 + 5 remaining dollars

Hope this helps!

Which table will have the greatest value of y when x = 7?
kow [346]

Answer:

(a) (x, y) = (7, 147)

Step-by-step explanation:

Table A represents a quadratic function: y = 3x², so for x=7, y = 3·7² = 147.

Table B represents a linear function: y = 12x +2, so for x=7, y = 86.

Table C represents an exponential function: y = 2^x, so for x=7, y = 128.

Table D represents a linear function: y = 10x +2, so for x=7, y = 72.

The greatest value of y for x=7 will be found in Table A.

_____

Table a's values go down and up, with symmetry about x=0. This suggests a quadratic function. A plain y=x² function will have the value 1 at x=1. This one has the value 3, so looks like y = 3x². Checking values for x=2 and x=3 confirms this.

Table b's values go consistently up, with a difference of 12 each time. The value for x=0 is 2, so we know this linear function has equation y=12x+2.

Table c's values double from one value of x to the next, so the function is exponential with a base of 2. The multiplier is 1, the value for x=0, so the equation is y = 1·2^x.

Table d is similar to table b, except the common difference is 10 instead of 12. So, the slope in slope-intercept form is 10 instead of 12: y = 10x + 2.

What's absolute value |-8|
maks197457 [2]
The absolute value of a number can never be negative. That's because it represents the distance of a number from zero on a number line. The number -8 is 8 digits to the left of zero on a number line. So, the absolute value of -8 would be 8 .

Let me know if you have any questions regarding this problem!
Thanks!

Jan borrowed $1200 at 11.5% interest for 3 months. How much does she have to repay under a single-payment plan?
vladimir2022 [97]


First, convert percent to decimal:

11.5% = 0.115

Multiply by amount borrowed:

0.115*1200= 138

Multiply interest amount per month (138) by 3

138*3 =$414.00 interest
