Your answer is B. 30. Here's why:

First, you do the parenthesis inside the parenthesis, which is 6 to the 2nd minus 4 to the 2nd. 6^2 is 36 and 4^2 is 16, and the difference is 20. Second we have 4x10÷20+1. With Order of Operations, you get 40÷20+1, then 2+1 and lastly 3. Finally after <u>these</u> parenthesis, you multiply by the 10 on the outside and your final answer, 30.

What is the equation of the line that is parallel to the given
Viefleur [7K]

Answer:

Any option that shares the same slope as the given line will be parallel to that line.

Step-by-step explanation:

I don't understand how your answers are laid out, so I can't give you the exact answer. But Slope-intercept form is y = mx +b, so any equation sharing the same slope (m), will be correct/parallel.

for example, if the given line is

y = 5x - 12

then the line

y = 5x + 23

will be parallel to y = 5x - 12.

The shared slope in this example is 5.

Solve the equations. Show the solution sets on a number line. Check your answers. c 9k+3 =−4
Naddika [18.5K]

Answer:

k = -7/9

Step-by-step explanation:

9k + 3 = -4

9k = -7

k = -7/9

On the number line just make a closed circle at -7/9. No line would be drawn, just the dot

-7/9 would be between 0 and -1, closer to -1
