Answer:

<h2><u>Graph A. </u></h2>

Step-by-step explanation:

Since you are looking for a graph that shows a function, answer A has to be correct. If you look at graph B, C and D, none of these are functions

You can check if a graph shows a function using the vertical line test. Make a vertical line on any x value and if it passes through 2 or more lines, it is NOT a function

Kamal invested $1200 in a savings acc paying 1.8% per yr compound interest.

Greeley [361]

Answer:

A = $1311 and 96cents

Step-by-step explanation:

$A = P(1 + \frac{r}{n})^{nt}$

P = $1200

r = 1.8% = 0.018

n = 1 (compounded yearly)

t = 5

$A = 1200(1 + 0.018)^5 = 1200 \times(1.018)^5 = 1311. 96$

If 15% is 375, how much is 5%

Nonamiya [84]

15% /3 = 5%

Since you have divided the % by 3 you can divide the 375 by 3

375 / 3 = 125

Find the equation of a line passing through a point (3,5) and perpendicular to the line joining the points (3, 7) and (7, -1)

eduard

Step-by-step explanation:

we start first by finding the gradient of the line

change in y/change in x

7-(-1)/3-7=8/-4

=-2

then for perpendicular lines m1m2=-1

therefore to find the gradient of that line

-2m2=-1

therefore m2=2

so therefore

y-5/x-3=2

so y-5=2x-6

y-2x=-1

in the form y= mx +c

then y=2x-1
