Would the answer be negative or positive -18-(-12)

Answers

Answer 1

Answer: the answer will be negative

Answer 2

Answer: It will be negative:
-18 - (-12)
When there is minus ( - ) and minus( - ), it becomes plus ( + )
so lets rewrite it:
-18 + 12
-6 will be the answer

And the answer is negative.

Marissa researched the cost to have custom T-shirts printed by several local and online vendors. She found that each store’s charge for the job could be modeled by a linear function that combined a flat charge for artwork with a per T-shirt rate. Marissa plotted the functions on a coordinate grid and found that two of the functions produced lines that had the same y-intercept. How should Marissa interpret this result?A.Those two vendors charge the same rate per shirt.
B.Those two vendors charge the same flat rate for artwork.
C.Those two vendors will have the same total cost to produce one shirt.
D.Those two vendors will charge the same total cost for any size job.

Answers

The correct answer is B. Those two vendors charge the same flat rate for artwork.

This is because the slope represents the rate of change of the function, or the rate per shirt, in this case. The y-intercept represents the flat rate for artwork, which can also be modeled as the cost of "0" shirts. This is the starting cost that will then be added to the rate that will change according to the number of t-shirts you buy.

Despite the same y-intercept, the total cost can change if the slope is different (this represents the rate per t-shirt) even if the same number of shirts are ordered (this eliminates options C and D).

Hope this helps!

Solving Linear Equat
Solve the linear equation:
3.4 + 2(9.7 – 4.8x) = 61.2

Answers

Answer:

Step-by-step explanation:

3.4 + 19.4 - 9.6x = 61.2

22.8 - 9.6x = 61.2

-9.6x = 61.2 - 22.8

-9.6x = 38.4

x = -4

Answer:

Step-by-step explanation:

Simplifying

3.4 + 2(9.7 + -4.8x) = 61.2

3.4 + (9.7 * 2 + -4.8x * 2) = 61.2

3.4 + (19.4 + -9.6x) = 61.2

Combine like terms: 3.4 + 19.4 = 22.8

22.8 + -9.6x = 61.2

Solving

22.8 + -9.6x = 61.2

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-22.8' to each side of the equation.

22.8 + -22.8 + -9.6x = 61.2 + -22.8

Combine like terms: 22.8 + -22.8 = 0.0

0.0 + -9.6x = 61.2 + -22.8

-9.6x = 61.2 + -22.8

Combine like terms: 61.2 + -22.8 = 38.4

-9.6x = 38.4

Divide each side by '-9.6'.

x = -4

Simplifying

x = -4

SOLVING SYSTEMS OF EQUASIONS BY ELIMINATION. -4x-2y=-12
4x+8y=-24

Answers

Your going to add the two equations to cancel out the x term. You get 6y=-36. Divide both sides by 6 and you get y=-6. Plug y in in your first equation and you'll get -4x-2(-6)=-12. Multiply the -2 by the -6 and you'll get -4x+12=-12. Subtract 12 from both sides and you get -4x=-24. Divide both sides by -4 and you get x=6. Your final answer is x=6, y=-6.

-4x-2y=-12
4x+8y=-24

Cancel out the x
6y=-36
Divide both sides by 6
y=-6

Substitute the value of y to any equation
-4x-2y=-12
-4x-2[-6]=-12
-4x+12=-12
-4x=-24
Divide both sides by -4
x=6
