Answer:

Step-by-step explanation:

Answer:

I'm guessing when it says "over the y-axis", it means to reflect it over the y-axis.

In that case, you would graph the points of the triangle, then flip them over the y-axis (change the x-values).

ex. R(-5,3)-R`(5,3)

Answer:

y=-3x-1

Step-by-step explanation:

Slope-intercept format:

y = mx+b

m = slope

b = y-intercept

Now we plug it in to get the equation:

y=-3x-1

I hope this helped!

Answer:

19

Step-by-step explanation:

1. Both angles would probably add up to 180 degrees.

2. So rewrite this as an equation. (2x + 3) + (9x - 32) = 180

3. Add up like terms like 2x and 9x which would be 11x

4. Rewrite equation again for less confusion. 11x + 3 - 32 = 180

5. Combine like terms again. Like terms this time are 3 and 32

6. 3 - 32 which would be negative 29

7. Rewrite equation again for less confusion. 11x - 29 = 180

8. Add 29 to both sides of equation meaning add 29 to 180.

9. You're left with 11x = 209

10. Divide 209 by 11

11. Lastly you get 19.

I hope this helped and that it's right!

Answer:

A)y=x²-11x+24

Step-by-step explanation:

Answer and explanation:

The connection of the rope from the stake to the pole will form a triangle so that one side is the hypotenuse(the rope), another is the opposite side(the pole) and the other is the adjacent side(the distance from the stake to the pole).

The unknown side is the adjacent side which is the distance from the stake to the pole. To find an unknown side in a triangle in this form, we use the Pythagorean theorem.

Therefore c²=a²+b²

c=20ft

a= 7ft

b= unknown

So we use the formula to find unknown side(distance from stake to base of pole)

20²=7²+b²

400=49+b²

b²=400-49

b²= 351

b=√351

b= 18.735ft

Therefore distance from stake to base of pole = 18.735 feet

Step-by-step explanation:

KM=11-7=4

if parallel, KM/KJ=LN/LJ

substituting:

4/11 is not equal to 3/8

Answer:

D

Step-by-step explanation:

We want to find the distance between (-6, 4) and (-8, 6).

We can use the distance formula given by:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]

Let (-6, 4) be (x₁, y₁) and let (-8, 6) be (x₂, y₂).

Substitute:

[tex]d=\sqrt{(-8-(-6))^2+(6-4)^2[/tex]

Evaluate:

[tex]d=\sqrt{(-2)^2+(2)^2[/tex]

Evaluate:

[tex]d=\sqrt{4+4}=\sqrt{8}[/tex]

Hence, our answer is D.

Answer:

1/3

Answer:

32

Step-by-step explanation:

Suppose Alvin is x years old. Then Elga is x+15 years old.

x+x+15=49

2x=34

x=17

17+15=32

Answer:

Length, l = 10 m, breadth = 8 m

Step-by-step explanation:

Let l be the length and b be the width of the rectangle.

The area of a rectangle is given by :

A = lb

80 = lb ...(1)

The perimeter of a rectangle is given by :

P = 2(l+b)

36 = 2(l+b)

18 = (l+b) ....(2)

We need to solve equation (1) and (2). On solving we get :

l = 10, b = 8

So, the dimensions of the shop is 10 m and 8 m.

Answer:

38%

Step-by-step explanation:

[tex]\frac{Part}{Whole}[/tex] × 100%

500 - 310 = 190

[tex]\frac{190}{500}[/tex] × 100% = 38%

Answer: £60

Step-by-step explanation:

Natalie bought a pair of shoes for £54 which had been reduced by 10%.

To find the original cost, assume the original cost is x.

The discount would be: 10% * x

The expression would therefore be:

x - (10% * x) = 54

x - 0.1x = 54

0.9x = 54

x = 54 / 0.9

x = £60

Answer:

D = 31

Step-by-step explanation:

Consider the equation showing the distributive property.

84 +93 = 3 (28+ D)

The unknown value we are asked to find is D

Hence:

84 + 93 = 84 + 3D

Collect like terms

84 - 84 + 93 = 3D

93 = 3D

D = 93/3

D = 31

Therefore, the unknown value that would make the equation true is 31

Answer:

x

=

0, 1/3

x=x^3-x/2-9

Step-by-step explanation:

Answer:

0.06

Step-by-step explanation:

m - 9 = 42

42 is our final answer so that should be by itself.

If something is being decreased by 9, that means that we are taking away 9 from something so it should be m - 9.

Answer:

m-9=42

Step-by-step explanation:

I'm pretty sure that m-9=42 is the correct answer because m or the amount is being decreased by 9 as 9 is being subtracted from it.

Answer: $18,375

Step-by-step explanation:

The person was earning $17,300 and got a 5% raise.

The $17,300 represents 100% of itself. If it were to increase by 5% therefore, the new salary would be: 100 + 5 = 105%

The new salary would be 105% of $17,300.

= 17,300 * 105%

= 17,500 * 105/100

= $18,375

Step-by-step explanation:

f(x) = 3x - 4

g(x) = x + 2

(f + g) = f(x) + g(x)

         = 3x - 4 + x + 2

         = 4x - 2

Domain: All real numbers

(f - g) = f(x) - g(x)

        = 3x - 4 - (x + 2)

        = 3x -4 -x -2

        = 2x -6

Domain: All real numbers

(fg) = f(x) * g(x)

     = (3x - 4)(x + 2)

     = 3x^2 + 6x -4x -8

     = 3x^ 2 + 2x - 8

Domain: All real numbers

Answer:

Well, there are 12 inches ina foot so let's multiply 56 by 12. Now, divide 672 by 8: 672/8 = 84 So, we have 84 which means that if we multiply 84 by 2.5 it should equal however many inches there are in 21, if it is to be a true scale model. It is not equal, so no, it is not a true scale model.

Step-by-step explanation:

HOPE THIS HELPS!!!

BRAINLIEST PLZ???

Answer:

It is not equal, so no, it is not a true scale model.

Step-by-step explanation:

Well, we need to find the ratio of it and see if both measurements of the 'scale' model are the same. But before we do, take in mind we can't divide 56/8 because 56 needs to be converted into inches.

56 • 12 = 672

divide 672 by 8:

672/8 = 84

So, we have 84 which means that if we multiply 84 by 2.5 it should equal however many inches there are in 21, if it is to be a true scale model

21 • 12 = 252

2.5 • 84 = 210

It is not equal, so no, it is not a true scale model.

Answer:

6 hours

Step-by-step explanation:

Ella takes 1 3/5 hours to complete a painting. Holly takes 3/4 of the time that Ella takes. How long will Holly take to complete 5 paintings?

Ella =1 3/5 hours = 8/5 hours

Holly = 3/4 of 8/5 hours

= 3/4 × 8/5

= (3*8)/(4*5)

= 24/20

= 6/5 hours

Number of hours : number of painting = 6/5 hours : 1 painting

How long will Holly take to complete 5 paintings

Let x = number of hours

Number of hours : number of painting = x hours : 5 painting

6/5 hours : 1 painting = x hours : 5 painting

6/5 ÷ 1 = x ÷ 5

6/5 × 1/1 = x / 5

6/5 = x / 5

Cross product

6 * 5 = 5 * x

30 = 5x

x = 30/5

x = 6 hours

It will take Holly 6 hours to complete 5 paintings
