please help me with this.

18-4y=42

4y = 18-42

4y=-24

y = - 6

Answer:

If the slope is the same but the intercept is different

i.e.

y=2x+1

y=2x+2

Step-by-step explanation:

If the slope is the same the lines are parallel, but if the y-intercept is also the same the lines have infinite solutions.

Answer:

5.67*10^7

Step-by-step explanation:

Since the distance from mercury to venus is 30,700,000, and the distance from venus to earth is 26,000,000, we can simply add these together to find the distance from mercury to earth:

 30,700,000

+26,000,000

__________

 56,700,000

Now, to convert it to scientific form, just multiply 10^7 (which is the number of digits-1) and 5.67. Therefore, the answer is 5.67*10^7

1 + -4

2 + -5

3 + -6

4 + -7

Answer:

5 + -8

6 + -9

7 + -10

8 + -11

Step-by-step explanation:

(2, −9) is a solution to the equation.

i took the quiz lol

Answer:

$1.26

Step-by-step explanation:

To get the cost of one pound you need to divide the cost of 4 pounds by 4.

5.04/4=1.26

$1.26 per pound.

Answer:

Joshua walked 48 feet in total.

Step-by-step explanation:

To find the total distance we need to sum every distance that he walked. We have:

- First: Joshua walked down the hall to the door = 14 feet

- Second: He continued in a straight line out the door and across the yard to the mailbox = 24 feet

- Third: He came straight back across the yard and stopped to pet his dog = 10 feet

Hence, the total distance is:

[tex] d_{T} = d_{1} + d_{2} + d_{3} = 14 ft + 24 ft + 10 ft = 48 ft [/tex]

Therefore, Joshua walked 48 feet in total.

I hope it helps you!

Answer:

D) all of the above

Step-by-step explanation:

If a line bisects another line, that means the length of the lines are equal

The lines are perpendicular because angle APR is 90 degrees

If the lines are perpendicular, then angle RPB is 90 degrees

Answer:

-19 degrees

Step-by-step explanation:

13+6=19

you would need to add the negative since it said dropped in temperature and the temperature was already negative.

Answer:

[tex]\boxed{\pink{\sf Value \ of \ third \ side \ is \ 7cm . }}[/tex]

Step-by-step explanation:

According to Question , equal sides of an isosceles triangle are given as 30 cm each if the perimeter of the triangle is 67 cm . And we need to find the third side .

Let us take the third side be x.

By Question ,

[tex]\implies Perimeter_{\triangle}= x + 30 cm + 30cm \\\\\implies 67cm = 60cm + x \\\\\implies x = 67cm - 60cm \\\\\underline{\boxed{\red{\tt\implies x = 7cm. }}}[/tex]

Hence the value of third side is 7cm.

Answer:

y is 4 times x

y is 4 more than x

sorry if im wrong

Answer:

Get ahead then

Step-by-step explanation:

Step-by-step explanation:

Shorts cost $16

T-shirts cost $10

So:

16x + 10y ≤ 100

or

y ≤ -1.6x + 10

Then graph y = -1.6x + 10 and x = 2

Part b:

Using the graph, we can infer that there are two possible solutions:

A. 3 pairs of shorts and 4 t-shirts

B. 4 pairs of shorts and 2 t-shirts

6a. X =  number of apples, Y = number of oranges

So:

x + y ≤ 20

0.24x + 0.8y ≤ 12

x ≤ 20 - y

0.24(20 - y) + 0.8 ≤ 12

= 4.8 - 0.24y + 0.8y ≤ 12

= 0.56y ≤ 7.2

y = 12.9 (You can use twelve because there can't be a fraction of an orange.)

x = 7.14 (again, because of fractions, round to 7.)

Therefore, she got 12 oranges and 7 apples.

Part 2:

Question 1:

Both equations are unbounded.

Question 2:

Both equations are unbounded.

Question 3:

Both equations are unbounded.

Question 4:

Both equations are unbounded.

Give me a moment to add question four's graph.

Answer: what is the question though

Step-by-step explanation:

What you do is you take the denominator and you divide it into the numerator.

Answer:

P(x) = 8Cx * p^x * (1 - p)^(8 - r) ; r = 0, 1, 2

Step-by-step explanation:

Given that:

Total Number of cameras (n) = 8

Defective cameras = 4

X: number of defective cameras

For a binomial distribution :

P(x) = nCx * p^x * (1 - p)^(n - x)

Probability of success (p) on each trial is the same = (total number of samples / number of defective samples) = 8/4 = 0.5

If 2 samples are chosen at random :

Then, the binomial probability distribution will be :

P(x) = 8Cx * p^x * (1 - p)^(8 - r) ; r = 0, 1, 2

96.666..., or about 97 minutes/every mile.
