Solve the system of equations:
4x - 3=-2x + 9


Answers

Answer 1

Answer:

x=2

Step-by-step explanation:

Step 1: Add 2x to both sides.

4x−3+2x=−2x+9+2x

6x−3=9

Step 2: Add 3 to both sides.

6x−3+3=9+3

6x=12

Step 3: Divide both sides by 6.

6x = 12

6 6

{9} Slope: -1

Y-intercept = 0

Step-by-step explanation:

Slope-----

Recall slope-intercept form

y=mx+b, with slope m and a y-intercept of b. With this in mind, we can rewrite our equation as y=−x+0

We see that our slope, or coefficient on x, is −1.

Y-intercept-----

We can rewrite this equation as:y=1x+0

The slope-intercept form of a linear equation is: y=mx+b

Where m is the slope and b is the y-intercept value.

For this equation:y=1x+0

Therefore:

The slope is m=1

The y-intercept is b=0 or (0,0)

ΔABD is similar to ΔBCD.

This means,

The corresponding sides ratio is equal.

AB/BC = BD/CD = AD/BD

AB/m = BD/7 = 11/BD

Now,

BD/7 = 11/BD

BD² = 77

BD = √77

Now,

ΔBDC

BC² = CD² + BD²

m² = 7² + 77

m² = 49 + 77

m² = 126

m = √126

Thus,

In ΔHIJ, the measure of ∠J=90°, the measure of ∠I=52°, and JH = 4.2 feet. Find the length of IJ to the nearest tenth of a foot.

Answers

I can use the angle and the length of JH to find the length of IJ.

To do this, I look at the relationship IJ and JH have to the 52 degree angle. JH is opposite to angle I, and IJ is adjacent to angle I. Because the two side lengths are opposite and adjacent, I use the tangent function to solve this.

Tangent of an angle = the length of the opposite side / the length of the adjacent side. This is just another way to say tan(x)=opposite/adjacent

Now I can fill in what I know...
tan(52)=4.2/x
Now, I want to isolate x.
tan(52) = 4.2/x
x(tan(52))=4.2
x=4.2/tan(52)

Now I put 4.2/tan(52) into a calculator and get x = 3.3 ft

Find the areas of these parallelograms, drawn on a centimetre grid.
b)

Answers

Answer:

a-16cm

b-12cm if not iwill look again

Step-by-step explanation:

Area of the parallelograms are :(a) = 16 cm² and (b) = 12 cm² which is drawn on a centimeter grid.

What is Parallelogram?

A parallelogram is defined as a special type of quadrilateral that has both pairs of opposite sides parallel and equal. A parallelogram is a square and a rhombus is a square.

The formula to calculate the area of a parallelogram can thus be given as,

Area of parallelogram = b × h square units

where b is the length of the base and h is the height or altitude

For parallelogram (a),

length of the base = 4 cm

the height or altitude = 4 cm

Area of parallelogram (a) = b × h =  4 × 4

Area of parallelogram (a) = 16 cm²

For parallelogram (b),

length of the base = 2 cm

the height or altitude = 6 cm

Area of parallelogram (b) = b × h =  2 × 6

Area of parallelogram (b) = 12 cm²

Given:

The rate of interest on three accounts are 7%, 8%, 9%.

She has twice as much money invested at 8% as she does in 7%.

She has three times as much at 9% as she has at 7%.

Total interest for the year is $150.

To find:

Amount invested on each rate.

Solution:

Let x be the amount invested at 7%. Then,

The amount invested at 8% = 2x

The amount invested at 9% = 3x

Total interest for the year is $150.

[tex]x\times \dfrac{7}{100}+2x\times \dfrac{8}{100}+3x\times \dfrac{9}{100}=150[/tex]

Multiply both sides by 100.

[tex]7x+16x+27x=15000[/tex]

[tex]50x=15000[/tex]

Divide both sides by 50.

[tex]x=\dfrac{15000}{50}[/tex]

[tex]x=300[/tex]

The amount invested at 7% is [tex]300[/tex].

The amount invested at 8% is

[tex]2(300)=600[/tex]

The amount invested at 9% is

[tex]3(300)=900[/tex]

Thus, the stockbroker invested $300 at 7%, $600 at 8%, and $900 at 9%.

The green gems are red gems divided by three. The red gems are gold gems divided by six. Make the number of gold gems, g. The red gems would be g/6, and the green gems (g/6)/2=g/18. So, the total marbles would be g+g/6+g/18=18g/18+3g/18+g/18=22g/18=11g/9. Now you have to find what percent of 11g/9 is g. (11g/9)(percent)=g. The percent as a fraction is 9/11.

Amelia was showing off her basketball skills. She scored a total of 14 shots for a total of 32 points. How many 2 point and 3 point shots did she make?

Answers

Answer:

Step-by-step explanation:

x+y=14

y=14-x

2x+3y=32, using y=14-x we have

2x+3(14-x)=32

2x+42-3x=32

-x+42=32

-x=-10

x=10, and since y=14-x

y=14-10=4

So Amelia made 10 two-pointers and 4 three-pointers.

A clothing manufacturer would like to determine whether celebrity endorsements influence a customer's decision to buy its products. In order to estimate this potential​ influence, the manufacturer premieres its latest series of commercials privately to two separate groups of potential buyers. One group will see a series of commercials without​celebrities, and one group will view a series of commercials with celebrities. The potential buyers are further divided by gender. Who is in the control​ group?
A.The women who see the commercials without celebrities.
B.The men and women who see the commercials without celebrities.
C.The 100 potential buyers.
D.The men and women who see the commercials with celebrities.
E.The men who see the commercials without celebrities.

Answers

Answer:

8

Step-by-step explanation:

The women who see the commercials without celebrities is in the controler group. Correct option is A.

In an experiment, the control group is a group of individuals who do not receive the specific treatment or intervention being studied. The purpose of the control group is to serve as a baseline for comparison, allowing researchers to evaluate the impact of the treatment by comparing it to the group that did not receive the treatment.

In this scenario, the clothing manufacturer is trying to determine whether celebrity endorsements influence a customer's decision to buy its products. To evaluate this influence, they are conducting an experiment with two separate groups of potential buyers:

Group A: Potential buyers (women) who will see a series of commercials without celebrities.

Group B: Potential buyers (men and women) who will view a series of commercials with celebrities.

The control group, in this case, is Group A - the women who see the commercials without celebrities. They do not receive the treatment (celebrity endorsements) being studied. Their responses and behavior will serve as a baseline against which the effects of celebrity endorsements on the buying decision can be compared in Group B.

By comparing the responses and behavior of the two groups, the clothing manufacturer can determine whether celebrity endorsements have a significant influence on the customers' decision to buy their products. The control group is essential for ensuring that any observed effects in Group B are not due to other factors but rather can be attributed to the presence of celebrity endorsements.

The area of a rectangle is 33ft, and the length of the rectangle is 5 ft less than twice the width. Find the dimensions of the rectangle

Answers

The dimensions are 164 ft (33x5=165)

Hi there!

[tex]\large\boxed{\text{ L = 6 ft, w = 5.5 ft}}[/tex]

Use the following equation for the area of a rectangle:

A = l × w

Since the length is 5 ft less than twice the width, we can write an expression for the length in terms of the width:

l = 2w - 5

Plug the given area and expression into the equation:

33 = (2w - 5) × w

Distribute:

33 = 2w² - 5w

Move everything over to one side:

0 = 2w² - 5w - 33

Factor the equation:

0 = (2w - 11)(w + 3)

Find each w value by setting each expression equal to 0:

0 = 2w - 11

11 = 2w

w = 5.5

0 = w + 3

-3 = w

Since dimensions must be positive, the width is 5.5 ft.

Plug this value into the initial equation to solve for length:

33 = 5.5l

33/5.5 = l

l = 6 ft.

The dimensions are length = 6ft, and width = 5.5ft.
