Answer:

The answer would be -2

Step-by-step explanation:

A trick I learned is that you can take the negative and turn it into a positive and add them but you have to remember the product would be a negative after if you are adding positive and a negative

Answer:

$\boxed{ -2}$

Step-by-step explanation:

On a number line

Adding a positive number means moving to the right
Adding a negative number means moving to the left

Using the number line,

Add 3 + (-5)

Step 1. Find 3 on the number line

Start at 0 and move three units to the right (see Image below).

This takes you to 3.

Step 2. Add (-5)

Start at 3 and move five units to the left.

This takes you to -2.

$\boxed{\textbf{3 + (-5) = -2}}$

8. Graph the following equation: y = x2 + 4x - 5

Dennis_Churaev [7]

Answer:

Given: y = x2 + 4x – 5

Find the following

y-intercept

x-intercepts or the zeros of the functions or roots

graph of the function, given vertex is at (-2, -9)

Solve the system of linear equations – x + 6y = 8 2x + 5y = 3

Write the names of curves, given their equations:

x2/16 + y2/9 = 1

3y = 2x + 5

(x - 5)2 + (y + 6)2 = 25

x2/16 – y2/25 = 1

y = 2x2 + 10x + 25

Write down the first five terms of the arithmetic progression with the first term 8 and common difference 7, then find the 17th

Write down the first five terms of the geometric progression with the first term 3 and common ratio 2, then find the 17th

Someone please HELP!?

jeka94

A negative exponent just means that the base is on the wrong side of the fraction line, so you need to flip the base to the other side.

For example

$x^{-2}=\frac{1}{x^2}$

or

$( \frac{2}{5} )^{-4}=( \frac{5}{2} )^4$

***************************************
$(8r^{-5})^{-3}$

$(8* \frac{1}{r^5} )^{-3} \\\\( \frac{8}{r^5} )^{-3}
 \\ \\ ( \frac{r^5}{8} )^3
\\\\ \mathrm{Apply\:exponent\:rule}:\quad *\left(\frac{a}{b}\right)^c=\frac{a^c}{b^c} \ \ \ \ \ \ \ \ \ \ \ \ *(a^b)^c=a^{bc}
 \\\\( \frac{r^{15}}{8^3} )
\\\\( \frac{r^{15}}{512} )$

The answer is "D"
