The correct answer is:

C. (1, 1/2) (2, 1/4) (3, 1/8) (4, 1/16)

Explanation:

In order to be an exponential function, the y-coordinates of each point should be multiplied by a constant to get the next y-coordinate. For C, we multiply by 1/2:

1/2(1/2) = 1/4; 1/4(1/2) = 1/8; 1/8(1/2) = 1/16

This means it is an exponential function.

GIVING BRAINLIEST Graph and solve the inequality y>-|x-5|-1

MakcuM [25]

Answer:

First, solve for two points as an equation instead of an inequality to find the boundary line for the inequality.

For:

(

)

For:

−

(

−

)

We can now plot the two points on the coordinate plane and draw a line through the points to mark the boundary of the inequality.

The boundary line will be solid because the inequality operator contains an "or equal to" clause.

graph{(x^2+(y-5)^2-0.125)((x+2)^2+(y-3)^2-0.125)(y-x-5)=0 [-20, 20, -10, 10]}

Now, we can shade the left side of the line.

graph{(y-x-5) >= 0 [-20, 20, -10, 10]}

Challenge Question Sally's bank account balance was $50 on Monday. On Tuesday, she bought a new pair of shoes for $45. On Thursd

Alex17521 [72]

Answer:

Step-by-step explanation:

After the shoe purchase, her balance was $50 -45 = $5.

After depositing her babysitting earnings, her balance was $5+25 = $30.

After buying pizza, her balance was $30 -42 = -$12.

Assuming no overdraft charge, her balance after depositing her earnings was ...

-$12 +20 = $8

Sally's balance on Sunday was $8.

Please find question in photo below. I’m revising for a test I have in a few days, and I can’t figure this out. Please help!

a) n² + 6

~Here n is the number of term. So, put n = 1,2,3,4.... to get the term.

If n = 1, first term = 1² + 6 = 7
n = 2, second term = 10
n = 3, third temm = 15
n = 4, fourth term = 22
n = 10, tenth term = 106

b) 3n²

If n = 1, first term = 3
n = 2, second term = 12
n = 3, third term = 27
n = 4, fourth term = 48
n = 10, tenth term = 300

What is the area of a triangle with a height of 13 cm and a base of a 10 cm?

Alecsey [184]

Area of a triangle is equal to 1/2 b(h) so since you already have the height and base, all you need to do is input it back into the equation:

$\frac{1}{2}$ (10)(13)

Multiply 10 & 13 to equal

$\frac{1}{2}$ (130)

Then take half of 130 to get

A = 65 $cm^{2}$
