Answer:

x=6 y=3

Step-by-step explanation:

Isolate x for -x+ 4y = 6: x= -6+ 4y

Substitute x = -6 + 4y

4(-6+ 4y) - 8y = 0

Simplify

-24+ 8y =0

Isolate y for -24 + 8y = 0: y =3

For x = -6+ 4y

Substitute y =3

X= -6+ 4 × 3

Simplify

X=6

The solutions to the system of equations are:

x=6 y=3

The function w(x) = 0.15x + 500 represents the relationship between Stephanie's wages and her monthly sales.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

Let's suppose the Stephanie's wages is w and weekly sale is x

So we can model a function:

[tex]\rm w(x) = \dfrac{15}{100}x+500[/tex]  or

w(x) = 0.15x + 500

Thus, the function w(x) = 0.15x + 500 represents the relationship between Stephanie's wages and her monthly sales.

Answer:

α=30, β=60

Step-by-step explanation:

we have angles α and β where α + β =90 & β=α+30

this gives us a system of equations that can be solved through substitution

[tex]\alpha +\beta =90\\\beta =\alpha +30[/tex]

substitute to solve for α: α+(α+30)=90

2α+30=90

2α=60

α=30

substitute α to find β:

β=α+30

β=(30)+30 = 60

Answer:

the answer is 41 degrees

Just subtract

180-139

=41

(Please katie im not doing anything wrong)

Step-by-step explanation:

Answer:

∠x=41°

Step-by-step explanation:

Supplementary Angles are angles that equal 180°

1. Use the equation

∠x+∠y=180°

2. Fill in the given values

∠x+139°=180°

3. Solve

Subtract 139 from both sides

∠x+139°=180°

      -139° -139°

4. Answer

∠x=41°

Answer:

0

Step-by-step explanation:

A constant velocity means no speeding up or slowing down. So the acclereation will be 0.

Answer:

Answer:

60 ft²

Step-by-step explanation:

in a cube all sides are congruent so you take one measurement and multiply it by the number of sides, so you do 12 × 6 equals 60.

Step-by-step explanation:

a. if AB=AC then arc(AB)=arc(AC), then arc(AC)=140°;

b. if arc(AB)=arc(AC)=140°, then arc(DC)=360-[arc(AB)+arc(AC)]=360-280=80°;

c. if arc(BC)=80°, then m∠A=0.5*arc(BC)=40°;

d.; e. if AB=AC and m∠A=40°, then m∠B=m∠C=0.5(180-m∠A)=0.5(180-40)=70°.

Hey there!

I believe your answer should be: OPTION B. because

7x + 2y - 14z = 56

7(8) + 2(28) - 14(4) = 56

56 + 56 - 56 = 56

112 - 56 = 56

56 = 56

So, that’s why possibly Option B. could be your result

Good luck on your assignment & enjoy your day!

Answer:

(f+ g)(x) = x^2 + 3x -3

Step-by-step explanation:

f(x) = 3x - 5 and g(x) = x² + 2,

(f+ g)(x) = 3x-5 + x^2 +2

Combine like terms

(f+ g)(x) = x^2 + 3x -3

Answer:

#9 24 T-Shirts for $168

#10 the diffirence between 30 T-Shirts and 9 T-Shirts is 147

Step-by-step explanation:

so to get the cost (c) for 1 T-Shirt you need to divide 147 by 21

147 ÷ 21 = 7

so c=7

10x7=70

70x3=210

30x7=210

so 30 shirts cost $210

and 9x7=63

so now it is time to do the rest of the math.

210

-63

147

Have a great day!
