Answer:
-8x+12
Step-by-step explanation:
1. You need to distribute the (-1) from outside the bracket onto all the terms in the bracket, which includes (8x) and (-12). If there is a minus outside the bracket and one minus in the bracket, the operation would be a plus and vice versa. If there is a minus outside the bracket and one plus in the bracket, the operation would be a minus and vice versa.
- (8x - 12) = (-1) × (8x) + (-1) × (-12)
= -8x + (+12)
= -8x + 12
can someone help me don't show my math hw? ily and tysm.
Answer:
Step-by-step explanation:
16)
[tex]\frac{4}{10} , \frac{32}{72}\\\\\frac{4}{10} = \frac{32}{72}[/tex]
Cross multiply,
4 * 72 = 32 * 10
288 ≠ 320
So, these are not in proportion.
17)
[tex]\frac{40}{25} = \frac{32}{20}[/tex]
Cross multiply,
40 * 20 = 32 * 25
800 = 800
So, these are in proportion.
18)
[tex]\frac{15}{45}=\frac{9}{c}[/tex]
Cross multiply,
15 * c = 9*45
c = [tex]\frac{9*45}{15}[/tex]
c = 9*3
c = 27
19)
[tex]\frac{16}{120} = \frac{v}{15}[/tex]
Cross multiply
16 * 15 = v * 120
[tex]\frac{16*15}{120} =[/tex] v
v = 2

Gina has a $50 gift card to a bagel shop. Each Friday, she purchases breakfast for $6. She created a graph to represent the amount of money on her gift card each week. Does Gina's graph represent the situation? Why or why not?
Math item stem image
CLEAR CHECK
Yes, because she starts with $50 on her gift card.
No, because the amount of money on her gift card should decrease each week.
Yes, because the amount of money that she spends increases each week.
No, because the graph should start at the origin.
Answer:
No, because the amount of money on her gift card should decrease each week.
Step-by-step explanation:
Well, the graph shows that the slope is increasing, if you got $50.00 and spend $6.00 each Friday, wouldn't that be decrease and not increase? This is why we eliminate the yes options. Lastly, of course, they should not start at the origin as they started at $50.00.

Step-by-step explanation:
I have attached an image of the graph of this inequality from Desmos, a virtual graphing website to help answer your question.
However, to explain this graph, each and every x value less than or equal to 5 would be an appropriate solution to the inequality, thus all values less than or equal to 5 are shaded in.

The Video Club charges a $100 membership fee and then charges $5 per movie. The Movie Market has a $25 membership fee and then charges $10 per movie. When will both clubs have the same cost? What is the cost?
Answer:
At 15 movies, both will cost $175
Step-by-step explanation:
Set it up algebraicly. Let x be the number of movies
100 + 5x = 25 + 10x
75 + 5x = 10x
75 = 5x
x = 15
Lets substitute x into one equation
100 + 5(15)
100+75
175

Twelve of the 20 students in Mr. Skinner’s class brought lunch from home. Fourteen of the 21 students in Ms. Cho’s class brought lunch from home. Siloni is using two 15-section spinners to simulate randomly selecting students from each class and predicting whether they brought lunch from home or will buy lunch in the cafeteria.
If each spinner is divided into 15 congruent sectors, how does the spinner representing Mr. Skinner’s class differ from the spinner representing Ms. Cho’s class?
One more sector of the Skinner-class spinner will represent bringing lunch from home.
One fewer sector of the Skinner-class spinner will represent bringing lunch from home.
Two more sectors of the Skinner-class spinner will represent bringing lunch from home.
Two fewer sectors of the Skinner-class spinner will represent bringing lunch from home.
Answer:its A, message if I'm wrong.

We are given a right triangle. We can use trig to find the missing length.
Step 2: Identify Variables
Angle = 31°
Opposite = 19
Hypotenuse = x
Step 3: Solve for x
