What is the solution to the system of equations?
y=1/2x-6
x=-4
O (8,4)
O (4, -8)
O (4,4)
O (4,-4)

Answers

Answer 1

Answer:

(-4,-8)

Step-by-step explanation:

Answer 2

The solution to the system of equations is,

⇒ (- 4, - 8)

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

The expressions are,

⇒ y = 1/2x - 6

⇒ x = - 4

Now, We can simplify the expression for y as;

⇒ y = 1/2x - 6

Put x = - 4;

⇒ y = 1/2 × - 4 - 6

⇒y = - 2 - 6

⇒ y = - 8

Thus, The solution to the system of equations is,

⇒ (- 4, - 8)

A jewelry store is having a going out of busniess sale. All merchandise is marked 40% off the reguler price. The regualr price of a watch is $59.95. Find the amount of the discount and the sale price.

Answers

Answer:

Amount of the Discount: $23.98

Sale Price: $35.97

Step-by-step explanation:

In order to calculate the discount we first need to turn this percentage into a decimal by dividing it by 100. Once we have it in decimal form we subtract that value from 1. Finally, we multiply this new decimal by the original price in order to obtain the sale price like so...

40 / 100 = 0.40

1 - 0.40 = 0.60

0.60 * 59.95 = 35.97

Now we have the sale price which is $35.97 now we can subtract this value from the original price to calculate the amount of the discount.

59.95 - 35.97 = 23.98

2. Solve (x – 4)(x + 7). (2 points) O x = 4, X= 7 X = =4, x = -7 x = 4, X = -7 X = -4, X = 7​

Answers

Answer:

X = 4, x = -7

Step-by-step explanation:

You can set each equation in the parenthesis Equal to 0.

x - 4 = 0 and x + 7 = 0

start with x - 4 =0

add 4 to both sides

x = 4.

then do x +7 =0. subtract 7 from both sides.

x = -7

so x =4, and x = -7

What is the scale factor in the dilation?​

Answers

Answer: 6

Step-by-step explanation:

The scale factor of the given dilation is 3.

Step-by-step explanation:
Step 1:
In order to determine the scale factor, we divide the measurement after scaling by the same measurement before scaling.
In the given graph, the preimage has a length of 3 units while the image has a length of 9 units.
Step 2:
So here the measurement after scaling is the length of the image which is 9 units and the measurement before scaling is the preimages length of 3 units. 9/3 = 3

So the scale factor is the third option 3.

You are a member of your local movie theater’s club. Every time you see a movie at the theater, you earn 2 advantage points. When you earn 100 points, you get a free movie pass. Currently, you have 40 advantage points.

Write an equation to model the number of movies m you have to watch before you earn a free movie pass.
Solve the equation. Show your work.

Answers

100=40+2m

100-40=60

2m=60

60 divided by 2=30

30 movies

Answer:

2m+40=100,  30 movies

Step-by-step explanation:

1 movie = 2 points

1 pass= 100 points

curently have 40 points so

100points = 40points +2points *m

solve for m:

2m+40 =100 subtract 40 from both sides

2m = 100-40

2m=60 divide both sides by 2

m=60/2

m=30

Two triangular tiles each have two sides measuring four inches. Which is a true statement?


A) Their corresponding angles are congruent.

B) The triangles are congruent.

C) The triangles may be congruent.

D) The triangles cannot be congruent.

Answers

Answer:

C; The triangles may be congruent

Step-by-step explanation:

Here, we have two sides of the each of the triangles equal already

By congruency, we might have SSS or SAS

if SSS, this mean that all the sides are equal

Since we do not know the measure of the third side, we cannot say that they are not congruent or they are congruent

Also, we do not know the measure of the angles of the triangles

If we have an angle that is equal in the two triangles, then we can have congruency through SAS

But since we do not know how these measures, we use the word ‘may’

if the transformation was a rotation, tiffany..... be certain the trapezoids are congruent

A. can
B. cannot​

Answers

can

Two figures are congruent when their corresponding angles are equal and they have the same shape and size.
A figure can go thorugh 3 types of transformations:
Rotation: the figure is turned around a fixed point;
Reflection: is created by fliping over the figure over a line;
Translation: move the figure to another location, without changing its size;
As long the figure doesn't change its size or shape, it doesn't matter if it's rotated, reflected or translated, they will be congruent.
When the trapezoid was rotated creating another one, the two shapes didn't change its size or shape, so Tiffany can be certain they are congruent.

The student council held a car wash to raise 200$ for the childrens hospital. In the first hour, they washed 2 cars. Each hour after that, the number of cars they washed increased by 2. How many cars did they wash by the end of 6 hours.

Answers

Answer:

Number of cars washed at the 6th hour = 12 cars

Sum of all cars washed in 6 hours = 42 cars

Step-by-step explanation:

First term, a = 2 cars

Common difference, d = 2 cars

6th term = a + 5d

= 2 + 5(2)

= 2 + 10

= 12 cars

Sum of the 6th term = n/2{2a + (n-1) d}

= 6/2{2*2 + (6-1)2}

= 3{4 + (5)2}

= 3{4 + 10}

=3(14)

= 42 cars
