Answer:

(7, 9)

Step-by-step explanation: To solve this system, I would use addition.

To solve a system of equations by addition,

we need one of our variables to cancel out.

Notice that we have a 4x in our first equation.

If we had a -4x in our second equation, the x's would cancel.

To create a -4x in the second equation,

we must multiply the entire equation by -4.

So we have (-4)(x + 6y) = (61)(-4).

Rewriting this equation, we have -4x - 24y = -244.

Now let's rewrite both equations.

4x - 5y = -17

-4x - 24y = -244

_____________

Now when we add the equations together, the x's cancel.

So we're left with -29y = -261.

Now divide both sides by -29 and we have y = 9.

To find x, we plug a y back in for x in either equation.

So let's go with our second equation, x + 6y = 61.

Plugging a 9 in for y, we have x + 6(9) = 61 or x + 54 = 61.

Subtracting 54 from both sides, we have x = 7.

So x = 7 and y = 9 which we can write as the ordered pair (7, 9).

Answer:

The equations of the line are

y + 7 = [tex]\frac{9}{7}[/tex] (x + 4) ⇒ B

y - 2 = [tex]\frac{9}{7}[/tex] (x - 3) ⇒ E

Step-by-step explanation:

The point-slope form of the linear equation is

[tex]y-y1=m(x-x1)[/tex] , where

∵ The line passes through points (-4, -7) and (3, 2)

∴ x1 = -4 and y1 = -7

∴ x2 = 3 and y2 = 2

→ Use the rule of the slope above to find it

∵ [tex]m=\frac{2--7}{3--4}=\frac{2+7}{3+4}=\frac{9}{7}[/tex]

∴ The slope of the line is [tex]\frac{9}{7}[/tex]

→ Substitute the values of m and (x1, y1) in the form of the equation above

∵ y - -7 = [tex]\frac{9}{7}[/tex] (x - -4)

∴ y + 7 = [tex]\frac{9}{7}[/tex] (x + 4)

∴ The equation of the line is y + 7 = [tex]\frac{9}{7}[/tex] (x + 4)

→ Substitute the values of m and (x2, y2) in the form of the equation above

∵ y - 2 = [tex]\frac{9}{7}[/tex] (x - 3)

∴ The equation of the line is y - 2 = [tex]\frac{9}{7}[/tex] (x - 3)

→  Look at the answers to find the same equations

∴ Answers B and E have the same equations

Given the question :

A shop sells matching hats and scarves. The scarves cost 1.5 times as much as the hats. Write 2 patterns that could represent the cost of 1,2,3,4,and5 hats and scarves list the first 5 terms of each pattern then write the cost of 6 hats and scarves using the patterns you wrote

Let cost of hats = h

Cost of scarves (s) = 1.5h

Hence of hat = $4 ; Scarve = 1.5 * 4 = 6

___________1__2___3___4___5

Cost of hat__ 4__8___12__16__20

Scarve cost__6__12__18__24__30

cost price * quantity sold

Cost of hat = 6 * $4 = $24

Cost of 6 Scarve = 6 * $6 = $36

Answer:

Step-by-step explanation:

#1

so 1st integer=35 and 1st integer=31

x=4+y

x+y=66

4+2y=66

2y=62

y=31

x=4+31

x=35

#2

1st integer = x 2nd integer = x - 8

(x) + (x - 8) = 50

x + x - 8 = 50

2x - 8 = 50

2x = 58

x= 29

so 1st integer = x = 29

and 2nd integer = x - 8 = 29 - 8 = 21

Answer:

20

Step-by-step explanation:

So in case you did not know, MNJ and KNL have the same angle measure, so to find x you would just set each of the eqautions equal to each other. distribute the 3 to (x + 14) and get 5x+  2 = 3x + 42. subtract 2 from one side and do the same on the other side. this would leave your eqaution looking like this: 5x-40= 3x, next subtract 5x from both sides and you will get  -2x=-40, then vide by -2 and x will equal 20

1/8 tablespoons

Step-by-step explanation:

Since the child needs to take 1/2 tablespoons off medicine per day in 4 equal doses, you will divide the 1/2 tablespoons into 4 equal doses, so you need to divide by 4.

You can do this by multiplying 1/2 by 1/4.

Step-by-step explanation:

In this question we proceed to translate each sentence into mathematical language and, more specifically, inequations:

a) At least 60 square feet of plywood for the surface

Let [tex]p[/tex] the surface area of plywood, measured in square feet, and the inequation is:

[tex]p \geq 60\,ft^{2}[/tex] (Eq. 1)

b) At least 36 feet of wood planks for the frame of the dog house

Let [tex]w[/tex] the total length of wood planks, measured in feet, and the inequation is:

[tex]w \geq 36\,ft[/tex] (Eq. 2)

c) Between 1 and 2 quarts of paint

Let [tex]q[/tex] the total capacity of paint, measured in quarts, and the inequation is:

[tex]1\,qt \leq q \leq 2\,qt[/tex] (Eq. 3)

d) Han's budget is $ 65. Plywood costs $ 0.70 per square foot, planks of wood cost $ 0.10 per foot and paint costs $ 8 per quart.

Dimensionally speaking, we understand that cost equals unit cost multiplied by physical variable (i.e. Area, length or capacity). Let [tex]p[/tex], [tex]w[/tex] and [tex]q[/tex] the surface area of plywood, the total length of wood planks and the total capacity of paint, respectively. The sentence is represented by the following inequation:

[tex]0.70\cdot p + 0.10\cdot w + 8\cdot q \leq 65[/tex] (Eq. 4)

Write an inequality to represent each constraint(material and cost)

Plywood:

plywood ≥ 60 square feet

Planks:

planks ≥ 36 feet

Paints

1 quarts ≤ paints ≤ 2 quarts

Inequality to represent cost constraint

Plywood = $0.70

planks of wood = $0.10

paint costs $8

Total cost = $65

0.70 × p + 0.10 × pw + 8 × Pa ≤ 65

0.70p + 0.10pw + 8pa ≤ 65
