Answer:

[tex]12x+9[/tex] and [tex]99[/tex]° are supplementary to each other.

Step-by-step explanation:

Supplementary means that two angles added together make 180°.

Looking at the graph, you can see that angles [tex]12x+9[/tex] and [tex]99[/tex]° both combined make 180°, so they are considered supplementary.

pls explain it​

Answers

Answer:

The six is bigger

Step-by-step explanation:

They both are inside the absolute value sign, meaning, the the numbers are negative, they will turn positive and if they are positive, then they will remain positive. So, in this case 4 and 6 are both positive and remain positive. And obviously 6 is greater than 4 because 6 comes after 4 in a number line.

he make? How many 3-point shots did he make?

Answers

Answer:

He made 7 3-point shots.

Mahni plans to spend the next 12 weeks saving some of her income. She will save $x a week for the first 6 weeks and then $(2x − 30) a week for the following 6 weeks. If she managed to save $213 in the first six weeks, how much did she save in total over 12 weeks? Explain correctly how to do this to get Brainliest ANSWER

Answers

$x=213$

For first six weeks she saved 213$

Now

For next 6weeks

[tex]\\ \sf\longmapsto 2x-30=2(213)-30=426-30=396\$[/tex]

Total savings:-

.[tex]\\ \sf\longmapsto 396+213=609\$[/tex]

Answer:

$459

Step-by-step explanation:

Mahni saved 6x in the first 6 weeks which is $213.

She saves in the next 6 weeks:

6*(2x - 30) = 12x - 180 = 2*6x - 180 = 2*213 - 180 = 246

Total saving is:

213 + 246 = 459

State the equation of the line described.
A line passes through the point (-3,7) and is perpendicular to the line y = -9x + -1.


thanks for your help!

Answers

Answer:

Step-by-step explanation:

Perpendicular lines have negative reciprocal slopes. This means that when you multiply the slopes of the perpendicular lines, its product = -1.

Given the linear equation, y = -9x - 1, and the point, (-3, 7):

Since the slope of the given linear equation is: m1 = -9, then it means that the slope of the other line (m2) = 1/9:

m1 × m2 = -1

-9 × 1/9 = -1

Next, we need to find the y-intercept of the other line. The y-intercept is the point on the line where it crosses the y-axis, and has coordinates (0, b). It is also the value of the y-coordinate when its corresponding x-coordinate = 0.

Using the given point, (-3, 7), and the slope of the other line, m2 = 1/9:

We need to substitute these values into the slope-intercept form, y = mx + b, to solve for the y-intercept, (b):

y = mx + b

7 = 1/9(-3) + b

7 =   -1/3 + b

Add 1/3 to both sides of the equation to solve for b:

7 + 1/3  = 1/3 -1/3 + b

22/3 = b

Therefore, the y-intercept (b) = 22/3.

The linear equation of the other line is: y = 1/9x + 22/3
