Substitution.
-3x - 2y = -12
y = 5x - 7

Answer:

See below

Step-by-step explanation:

Because a constant never changes. It stays constant (it's in the word)! The function never changes since the slope is 0, therefore there's no vertical change.

Answer:

Step-by-step explanation:

The function value never changes and is always graphed as a horizontal line so theirs slopes become zero. This means there is no change that is vertical within and throughout the function.

Answer:

11x=1

Step-by-step explanation:

15x+4=5+3x+1x       Bring everything with an x in front of it to the left side

15x-3x-1x+4=5         Simplify the x values

11x+4=5                    Bring the 4 to the right side

11x=5-4

11x=1

Answer:

18.86 m

Step-by-step explanation:

From the given question, both covers the same distance of the straight line segment.

For the inner lane,

length of arc of its semicircle = [tex]\pi[/tex]r

                                   = 30 x [tex]\frac{22}{7}[/tex]

                                   = 94.2857

So that,

the total length for the two halves of the inner lane = 2 x 94.2857

                                                                  = 188.5714 m

For the outer lane,

length of arc of its semicircle = [tex]\pi[/tex]r

                                                 = 33 x [tex]\frac{22}{7}[/tex]

                                                 = 103.7143

The total length for the two halves of the outer lane = 2 x 103.7143

                                                                  = 207.4286 m

The difference between the two = 207.4286 - 188.5714

                                                       = 18.8572 m

Therefore, Devin would run 18.86 m more to complete one lap.

Answer:

The cost per ounce is $0.23

Step-by-step explanation:

Set up fraction:

ounce/cost

15.4/3.59 = 1/x

cross multiply

15.4x=3.59

x=3.59/15.4

x=0.233116883117

x=$0.23

The cost per ounce is $0.23

Answer:

$0.23

Step-by-step explanation:

[tex]\frac{15.4}{3.59} =.23.........[/tex]

$0.23

Answer:

B

Step-by-step explanation:

Since here, 100x = 1, and since we already have one, we can leave that aside. It would never be d because that is way larger. The second square is 6/100 and since earlier we said 100x = 1, we would have to make an equation. Your answer is B

Answer: 3.) 2.5 inches

Step-by-step explanation:

 x                 32.5

Answer:

y=-4.2

Step-by-step explanation:

2.9=7.1+y

2.9-7.1=7.1-7.1 +y

-4.2=y or y= -4.2

y = -4.2

If you substitute that value for y into the equation, you'll get 2.9 = 7.1 + (-4.2)... and that is a correct, valid equation. HOPE THAT HELPS!

Answer:

Step-by-step explanation:

Multiply both sides by 5(k - 2)

-8*5(k - 2) ≤2               Combine -8 and 5

-40 (k - 2) ≤2                Remove the brackets

-40k + 80 ≤2               Subtract 80 from both sides

-40k ≤ -78                    Here's the trick part. Pay attention. Divide by - 40

k ≥ - 78 /- 40

k ≥ 1.95

Did you see what happened? The ≤ operation turned into ≥ That always happens when dividing by a minus or multiplying by a minus or if you change the side where literal coefficient is.

Answer:

Center (7,2) and radius = 10

Step-by-step explanation:

Generally, we have the equation of a circle as follows;

(x-a)^2 + (y-b)^2 = r^2

where (a,b) represents the circle center and r represents the radius of the circle

Looking at the given equation of a circle, we have it that the center is (7,2) while the radius of the circle is 10
