Answer 1

Answer:

1. y = -2x + 5

2.  y = 3/5x + 5

3. y = -4/5x - 4

4. y = - 1

5. yes

6. yes

7. yes

8. no

Step-by-step explanation:

1.   (4,-3) parallel to y= -2x

     -3 = -2(4)+b

     b=5

2. (-5,2) parallel to y = 3/5x

    2= 3/5(-5)+b

     b=5

3. (-5,0) -4/5x

   0 = -4/5(-5)+b

    b = -4

4. (-4,-1)

    y= -1

5. yes

6. yes

7. yes

8. no

Same slope = parallel ex. y = -5x +7, y = -5x +12opposite reciprocal  = perpendicular ex. y = -5x +7, y = 1/5x + 12to find "b" with slope and point

          (x,y)  y = mx + b

          plug in the y value and x value in the eqaution and m=slope, solve for b

Find the equation of the line that is parallel to the given line and passes through the given point.

y = −5x + 1; (5, 7)

Answers

See attachment for math work and answer.

The equation we are looking for is parallel to the given equation. This means both equations have the same slope.

Answer:

y = -5x + 32

Step-by-step explanation:

y = -5x + 1

=> (d): 5x + y - 1 = 0

d' is parallel to the given line and passes through the given point

=> (d'): passes through (5;7)

           // (d): 5x + y - 1 = 0

=> (d'): 5x + y - 32 = 0 <=> y = -5x + 32

jessica will babysit children for $8 an hour. ciara will babysit for an appointment fee of $12 and $4 an hour. how many hours would they need to work to earn the same amount of money? if a baby sitter was needed for 5 hours, who would be less expensive?

Answers

Answer:

Answer are in bold below

Step-by-step explanation:

Question: 1

Jessica = $8

Ciara = $12 + 4 $16

Now we times both values.

16 x 8 = $128

8 x 16 = $128

They would both need to work 8 hours ft=or the same money.

Question 2:

$8 x 5 = $40

$16 x 5 =$80

Jessica will be less expensive.

Answer: 3 hours

Jessica=$8

Ciara= $4 + $12

8*3= $24

4*3= $12 +$12= $24

Because Ciara has an additional $12 fee, you have you add it on to her total.

What is the y-intercept of the line?

Answers

Answer:

The Y-intercept is 1

It is where the line meets the y-axis

~PumpkinSpice1

hello!

[tex]==================================[/tex]

Remember, the y-intercept is the point where the graph touches the y-axis (that's why it's called y-intercept).

Let's look at this graph and see if we can identify the y-intercept of the line.

If we look at our graph, we'll see that the line touches the y-axis at (0, 1).

[tex]\pmb{Note:-}[/tex] Remember, y-intercepts have an x-coordinate of 0.

And guess what the y-coordinate is? Yes, it's the y-intercept of the line.

Hence, the y-intercept of the line is

Find x and y intercept and graph -3 + 2y = -5

Answers

x intercept = none
y intercept = -1

Answer:

( [tex]\frac{5}{3}[/tex] , 0 ) ; ( 0 , - [tex]\frac{5}{2}[/tex] )

Step-by-step explanation:

- 3x + 2y = - 5

Coordinates of x-intercept are (x, 0)

- 3x + 2(0) = - 5 ⇒ x = [tex]\frac{5}{3}[/tex]

Coordinates of y-intercept are (0, y)

- 3(0) + 2y = - 5 ⇒ y = - [tex]\frac{5}{2}[/tex]

The total cost for tuition plus room and board at State University is 6,584
dollars. Tuition costs 1804 dollars more than room and board. What is the
tuition fee?

Answers

Answer:

$4,194

Step-by-step explanation:

First, you need to subtract the 1,804 from the the total, which will give you 4,780. Divide this by two to get the cost of room and board, which is 2390. To find the tuition fee, add 2,390 and 1,804, and that equals $4,194.

first to answer corretly gets brainleist! I need ya to find the slope for me!

Answers

Answer:

The slope is 3.

Step-by-step explanation:

To find the slope of this line you just have to figure out the rise over run. The rise is positive because it's going up. The run is also positive because it's going to the right. The rise would be 2 because that's how many units up the line goes until it crosses the y-intercept. The run is 3 because that's how many units over until it crosses the y-intercept. But, in this case we are not using a fraction so we just use the run which is 3.

On multiple-Choice history Test, rita received a mark of 80%. She answer 32 correctly

Answers

Let total number of questions be x.

According to the question,

80% of x is 32

or 80/100 × x = 32

or x = 32 ÷ 80/100

or x = 32 × 100/80

or x = 32 × 10/8

or x = 4 × 10

or x = 40

So, total number of questions is 40.

Each figure in the sequence shown is composed entirely of 1 × 1 shaded squares. If the pattern is continued, find the quotient of the area of the enclosed inner square to the sum of the areas of the shaded squares in the 2020th figure.

Answers

Answer:

505

Step-by-step explanation:

you first do 2020x2020 because you can see from the pattern, the inside squares are 1x1, 2x2, 3x3, so the 2020th inside squares would be 2020x2020. then, you would do 2020x4 for the shaded squares because if you see from the pattern, its 1x4, 2x4, 3x4, so the 2020th would be 2020x4. then you divide [tex]\frac{2020*2020}{2020*4}[/tex] which is 505.
