Answer 1

Answer:

C.) This system has infinitely many solutions.

Step-by-step explanation:

y = 2x - 4

2x - y - 4 = 0

2x - y - 4 = 0 can be rewritten as y = 2x - 4 as shown below

2x - y - 4 = 0

-y = -2x + 4

-y/-1 = -2x/-1 + 4/-1

y = 2x - 4

y = 2x - 4 is equal to 2x - y - 4 = 0 because the slope is both 2 and both its y-intercept is -4, these two are coincidence, as they call it, meaning these two lines are the same, so its solutions are anywhere on its line. Shown below in a graph.

Solve for x:122+4x=3x+87

Answers

Answer:

122+4x=3x+87

the first step is to move the variable and constants because we can not add variable and constants together we will move 3x and 122 it will be something like this: 3x-4x=122-87 now that the constants and variables have moved we can solve it because we moved them the addition symbol will become a subtraction symbol the answer will be: 1x=35

Step-by-step explanation:

122+4x=3x+87

3x-4x=122-87

1x=35

Calliope Is going to buy a television for $1349. If sales tax is 8%, find the price of the television including tax.

Answers

Answer:

The price including tax is $1,456.92

Step-by-step explanation:

First we need to convert our percentage into a decimal.

0.08

Now we need to multiply our price by the sales tax.

$1,349.00 × 0.08 = $107.92

Our sales tax is $107.92.

Added to our price it's $1,456.92.

Tamika wants to predict the outcome of next Tuesday’s game, between the Nets and the Warriors.
She believes that the Warriors will score 19 points less than the Nets. Tamika also predicts that the total amount of points scored for both teams will be 207 points.

How many points does Tamika think that the Warriors will score? How many points will the Nets score?

Answers

Step-by-step explanation:

Let x be the Warriors' score. Then from Tamika's prediction, (x + 19) is the Nets' score.

Toal score = x + (x + 19) = 2x + 19 = 207.

Therefore 2x = 188 and x = 94.

Hence Tamika thinks that the Warriors will score 94 points and the Nets will score 94 + 19 = 113 points.

Use the diagram below in which P is the incenter of JKL, PN =21 and ML=27 . Find PO, LO, and PL

Answers

Answer:

1. PO = 21

2. LO = 27

3. PL = 34.2

Step-by-step explanation:

1. Since P is the incenter, that means it is equidistant to each side at a right angle. As a result PN, PO, and PM are equal to each other.

We know that PN is 21. Since PN and PO are equal to one another, PO = 21.

2. ML is equal to LO. ML is 27, so LO is also 27.

3. To get PL you will have to do the Pythagorean Theorem. Square the legs and set it equal to the hypotenuse squared.

* It should be: 27^2 + 21^2 = x^2.

Once you solve and round to the nearest tenth, you will get 34.2.

What is Transformation?

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.

We have,

The coordinate of A(10 ,2)

Now, When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places.

Then, the pre image of vertex A' is (2, 10).

equations with variables on both sides: decimals & fractions, 6d - 11/2 = 2d - 13/2

Answers

Step-by-step explanation:

i work in paper sheet please see it

Final Answer: [tex]d = -\frac{1}{4}[/tex]

Steps/Reasons/Explanation:

Question: Equations with variables on both sides: decimals & fractions, [tex]6d - \frac{11}{2} = 2d - \frac{13}{2}[/tex].

Step 1: Subtract [tex]2d[/tex] from both sides.

[tex]6d - \frac{11}{2} - 2d = -\frac{13}{2}[/tex]

Step 2: Simplify [tex]6d - \frac{11}{2} - 2d[/tex] to [tex]4d - \frac{11}{2}[/tex].

[tex]4d - \frac{11}{2} = -\frac{13}{2}[/tex]

Step 3: Add [tex]\frac{11}{2}[/tex] to both sides.

[tex]4d = -\frac{13}{2} + \frac{11}{2}[/tex]

Step 4: Simplify [tex]-\frac{13}{2} + \frac{11}{2}[/tex] to [tex]-1[/tex].

[tex]4d = -1[/tex]

Step 5: Divide both sides by [tex]4[/tex].

[tex]d = -\frac{1}{4}[/tex]

Answer:

The solution to the inequality is:

[tex]x<5[/tex]

The number line solution graph is also attached below.

Step-by-step explanation:

Given the inequality

[tex]2(x-3)-8< -4[/tex]

Add 8 to both sides

[tex]2\left(x-3\right)-8+8<-4+8[/tex]

[tex]2\left(x-3\right)<4[/tex]

Divide both sides by 2

[tex]\frac{2\left(x-3\right)}{2}<\frac{4}{2}[/tex]

[tex]x-3<2[/tex]

Add 3 to both sides

[tex]x-3+3<2+3[/tex]

[tex]x<5[/tex]

Thus, the solution to the inequality is:

[tex]x<5[/tex]

The number line solution graph is also attached below.
