A line includes the points (7, –7) and (11, –3). What is its equation in slope-intercept form?

[tex] \: \: \: \: \: \: \: \: [/tex]

[tex]x = - 1 \\ x = \: 7[/tex]

Step-by-step explanation:

[tex]2(x - 3 {)}^{2} - 32 = 0[/tex]

[tex](x - 3 {)}^{2} - 16 = 0[/tex]

[tex](x - 3 - 4) \times (x - 3 + 4) = 0[/tex]

[tex](x - 7) \times (x + 1) = 0[/tex]

[tex]x - 7 = 0 \\ x + 1 = 0[/tex]

[tex]x = 7 \\ x + 1 = 0[/tex]

[tex]x = - 1 \\ x = 7[/tex]

Parallel means same slope, so in the image, line PQ is connected by a line. The other point I made has a line parallel through it.

Answer:

x = t - q

Step-by-step explanation:

because to make q, you need to add x and t

so to make x the subject, you should subtract q

Example

x + t = q

t = 7

q = 36

x = t - q

36 -7 = 29

x = 29

Answer:

34

Step-by-step explanation:

634 - 600 = 34

Answer:

89.6875

Step-by-step explanation:

you need to find out area of rectangle (length x width) and add area of the triangle (length x width divided by 2)

Answer:

A, a dilation of 2

Step-by-step explanation:

The answer is, A dilation of 2 because the image is getting dilated to a  bigger form. If it was a decimal or a fraction; the image would be smaller and than the pre-image.

(Pre-image is a shape before a transformation, image is after a ransformation.)

Have a great day friend! :D

Answer:

Step-by-step explanation:

The blanks get filled in like this:

Statement 3: m∠6 +m∠4 = 180°

Reason 3: Consecutive interior angles are supplementary

Statement 4: m∠6 +8·m∠6 = 180°

Statement 5: m∠6 = 20°, m∠4 = 160°

_____

You can see from the diagram that angles 4 and 6 are consecutive interior angles. You know the relation between those angles is that they are supplementary. The problem is asking you to state that relationship as Reason 3.

The given relation between the angles, m∠6 = 1/8·m∠4, can be recast as ...

  8·m∠6 = m∠4

This is the substitution that is used in statement 4.

Simplifying that statement gives 9·m∠6 = 180°   ⇒   m∠6 = 180°/9 = 20°. Then m∠4 = 8·m∠6 = 8·20° = 160°.

Answer:

y = -5/3x + 8

Step-by-step explanation:

So the y - intercept is 8 and from that point the line goes down by 5 and right by 3.

Answer:

2x-6 I think

Step-by-step explanation:

Answer:

x = -4

Step-by-step explanation:

2x=-2+10

-2=8

x=-4

Answer:

3x-18+8=5x-2

3x-10=5x-2

3x-5x=-2+10

-2x=8

X=-4

Step-by-step explanation:

Have a great day

Answer:

answer is D

pls I don't confirm sorry

Answer:

15

Step-by-step explanation:

For each time I see x, I replaced it with 7 because I know that x is equal to 7.

I only see one x so I am only replacing that one x so instead of x + 8, I get 7 + 8 and you could split 8 into 5 + 3 and split 7 into 5 + 2.

5 plus 5 is 10. If you are having trouble adding the numbers you could put up 5 fingers first and then add one finger up one by one to still the number 10. Now that just leaves you with 3 + 2.

You could first put up 3 fingers and then add two more to get a total of 5 fingers.

At last, you could just add 10 + 5 to get 15 in total.

Hope this works you!!!

Step-by-step explanation:

Answer:

y = 0.7 * 1.2^x

Step-by-step explanation:

(1, 0.84)

0.84 = ab^1

(2, 1.008)

1.008 = ab^2

-------------------------

To find b divide the second point by the first

ab^2 / ab^1 = 1.008 / 0.84

b = 1.2

----------------------

To find a plug b = 1.2 into the first point

0.84 = a * 1.2^1

0.84 = a * 1.2

Divide both sides by 1.2

0.7 = a

------------------------

The equation is

y = 0.7 * 1.2^x

Answer:

21gb

Step-by-step explanation:

did the test

A.

Step-by-step explanation:

To find out the answer, there is a method that can be used to find out if a line is a function. It is called the vertical line method. And it also has to be per x, One y value has to be there. Analyzing the graphs, the answer should be option A.

Step-by-step explanation:

Start by squaring both sides

cosA+sinA=[tex]\sqrt{2}[/tex]

[tex]cos^2A+2cosAsinA+sin^2A=2[/tex]

Apply Trig identity

[tex]cos^2x+sin^2x=1[/tex]

2cosAsinA+1=2

2cosAsinA=1

Apply Trig Identity

2cosxsinx=sin(2x)

sin(2A)=1

2A=arcsin1

arcsin(1) is a known value [tex]\frac{\pi }{2}[/tex]

2A=[tex]\frac{\pi }{2}[/tex]

A=[tex]\frac{\pi }{4}[/tex]

[tex]\pi[/tex] [tex]radians=180^o[/tex]

A=[tex]\frac{180^o}{4}[/tex]=[tex]45^o[/tex]

Answer:

You can use ratio to compare the input and output

Step-by-step explanation:

Answer:

The slope is 10

The y - intercept is 20

Step-by-step explanation:

The equations are written as:

y = ?x + ?

The first ? is the slope of the equation, every time y increases by that amount, x increases by one, the slope here is 10

The second ? is the y-intercept, or the place where x is 0. Here, when x is 0, y is 20, so it is the y-intercept

Answer:

Point slope form

Answer:

22

Step-by-step explanation:

Answer: b

Step-by-step explanation:

Answer:

B.

Step-by-step explanation:

The shading is above the line, so it must be ≥ or >.

The line is solid, so it must be ≥.

The only choice with ≥ is the answer.

Answer: B.
