The second question is multiple choice.

1.) Describe how the graph of y=2x is the same AND different from the graph of y=2x-7. EXPLAIN. ?

2. Use the photo for this question! This is a multiple choice question.

What is the equation for the line below (the photo)

Y = 1x + 2

Y = 2x + 1

Y=2x

Y = 1 -2

Answers

Answer 1

Answers:

Question 1: The equations share the same slope, but different y-intercepts.

Question 2: Option B (y = 2x + 1)

Explanations:For Question 1:

Both equations are written in slope intercept form.

[tex]y = mx+b\\\\\text{m - slope}\\\text{b - y-intercept}[/tex]

The equations we have are:

[tex]\left \{ {{y=2x} \atop {y=2x-7}} \right.[/tex]

Both equations share the same slope of 2. However, they have different y-intercepts.

y = 2x can be written as y = 2x + 0.

Usually if you only have the slope in your equation then the y-intercept is the origin, or (0, 0).

The second equation's y-intercept is -7. It takes 'b's place.

For Question 2:

We are given a graph and we need to find a equation.

According to the graph, the line passes at (0, 1). 1 is the y - intercept.

Since y = 2x + 1 is the only option with 1 as the y - intercept, it should be the correct answer.

I'll do the slope as well to verify our answer.

I will use the points (-1, -1) and (1, 3).

[tex]m=\frac{3-(-1)}{1-(-1)}=\frac{4}{2} =\boxed{2}[/tex]

The correct answer should be [tex]y = 2x+1[/tex].

Hope this helps you.

solve,y=5 and 3x +2y=-5

Answers

Answer:

x = -5

Step-by-step explanation:

I) Substitute:

3x + 2y = -5

3x + 2(5) = -5

3x + 10 = -5

II) Solve:

3x + 10 = -5

3x = -15 (Subtract 10 from both sides)

x = -5 (Divide both sides by 3)

Answer:

x = -5

y = 5

Step-by-step explanation:

We are given the system of equations :

3x + 2y = -5

y = 5

This can be solved through the process of substitution, mainly because y in the second equation already has a value in of its own and can be replaced with the y in the first equation. Therefore :

3x + 2y = -5

y = 5

3x + 2(5) = -5

3x + 10 = -5

Solve for x, first by subtracting ten by both sides :

3x = -15

Divide 3 by both sides to isolate x :

x = -5

Now that we have x, we have solved our system of equations, but let's prove it first.

x = -5

y = 5

3(-5) + 2(5) = -5

-15 + 10 = -5

Therefore, our two variables are x = -5 and y = 5

2.5, 2.304, 3.21, 2.34

Answers

Answer:

2.304, 2.34, 2.5, 3.21

Step-by-step explanation:

1. Look at the digit in the ones place. See how they are all 2s except for one 3? Well, now we know the one with the 3 must be the greatest, since 3>2.

2. Next, look at the digit in the tenths place. We have a 3, 3, and a 5. Since 5 > 3, we know thar 2.5 is the second greatest.

3. Last, look at the hundreths place. We have a 0 and a 4. Since 4 > 0, that means 2.34 is the third greatest.

4. Since this is from least to greatest, put 2.304 first and the others as follows in the answer. Hope this helps.

Members were charged $2995 a head. Did the club make a profit
Justify your answer.

Answers

Answer:

They made a profit of 7,130 dollars.

Step-by-step explanation:

So since they were charged 2995 a head then all youd have to do is multiply that by the number of people.

2,995 x 62 = 185, 690

Then add the total of the food.

44,640 + 59,520 + 42,800 + 31600 = 178,560

Then subtract their income from the money they spent.

185,690 - 178, 560 = 7,130

If nkf ~ lzf, find nf, please help me with this it’s due tmr!!!!

Answers

Answer:

NF = 25

Step-by-step explanation:

Since ∆NKF ~ ∆LZF, the ratio of their corresponding side lengths would also be the same.

This means that:

KF/ZF = NF/LF

KF = x + 3

ZF = 4

NF = 15 + x + 3 = x + 18

LF = x + 3

Plug in the values into the equation

(x + 3)/4 = (x + 18)/(x + 3)

Cross multiply

(x + 3)(x + 3) = (x + 18)(4)

x² + 3x + 3x + 9 = 4x + 72

x² + 6x + 9 = 4x + 72

x² + 6x + 9 - 4x - 72 = 0

x² + 2x - 63 = 0

Factorize to find x

x² + 9x - 7x - 63 = 0

x(x + 9) -7(x + 9) = 0

(x + 9)(x - 7) = 0

x + 9 = 0 or x - 7 = 0

x = -9 or x = 7

We'd use the positive value of x, which is 7.

Therefore, x = 7.

✅NF = 15 + (x + 3)

Plug in the value of x

NF = 15 + (7 + 3) = 15 + 10

NF = 25
