Which system of equations has a solution of (–3, –1)?

A: y = –3x – 10
y = x + 4

B: y = –3x – 1
y = –x – 3

C:y = 2x – 1
y = 5x + 2

D:
y = 2x + 5
y = 5x + 14

Answers

Answer 1

Answer:

The answer is D!

Step-by-step explanation:

You can look for the x value by replacing the y from one of the two equations with (-1) or (-3) so you get -3y=10x-28.

Answer 2
Yes, the answer is D. I'm 100% sure.

Which situation can be represented by this inequality?

135 ≤ 10r + 15

Question 8 options:

A Hugo has 10 songs in his music player. He will add 15 songs every month. Hugo collects songs for r months. For what values of r will Hugo have at most 135 songs?


B Hugo has 10 songs in his music player. He will add 15 songs every month. Hugo collects songs for r months. For what values of r will Hugo have at least 135 songs?


C Hugo has 15 songs in his music player. He will add 10 songs every month. Hugo collects songs for r months. For what values of r will Hugo have at most 135 songs?


D Hugo has 15 songs in his music player. He will add 10 songs every month. Hugo collects songs for r months. For what values of r will Hugo have at least 135 songs?

Answers

Answer:

D

Step-by-step explanation:

So the key to figuring this equation is writing it out. If Hugo already has 15 songs, then he will add 15 at the end for his collection. If he gets 10 every month, for r months, you must multiply them for 10r. You do this because you get 10 for r, the amount of months. This is where you add the 15, since it is your collection total.

so far we have 10r + 15

For teh last part we see that the equation, 135 ≤ 10r + 15, says that 135 is less than or equal to our 10r +15. This means that D has to be the answer since nothing else will fit.

Which ordered pair is a solution of the equation?
y=-2x-5
Choose 1 answer:
A. Only (1,7)
B. Only (2,-7)
C. Both (1,7) and (2,-7)
D. Neither

Answers

Answer:

D

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

Just plug the numbers in.

y=-2x-5

(Plug in 1,7)

7=-2(1)-5

7=-7

So not (1,7)

y=-2x-5

(Plug in 2,-7)

-7=-2(2)-5

-7=-9

So not (2,-7)

Which means none of these answers are correct.

The only correct solutions to this equation are (0,-5) and (1,-7)

Write in slope-intercept form an equation of the line that passes through the points (−4, 2) and (6,−3).


y=

Answers

Answer:  

y = [tex]-\frac{1}{2}[/tex]x  

Step-by-step explanation:  

Slope-intercept form: y = mx + b  

    [] m is the slope  

    [] b is the y-intercept  

Slope  

We can find slope by using change in y over change in x:

[tex]\frac{-3-2}{6--4}=\frac{-3-2}{6+4} =\frac{-5}{10} =\frac{-1}{2}[/tex]  

    [] So our slope is [tex]-\frac{1}{2}[/tex]    

Y-intercept  

We will plug in one of the points into our equation so far, and solve for b:  

    y = [tex]-\frac{1}{2}[/tex]x + b  

    (2) = [tex]-\frac{1}{2}[/tex](-4) + b  

    2 = 2 + b

    0  = b

The formula V=R-N describes the variation V of the recorded temperature R from the normal temperature N. If the recorded temperature is -4.6 degrees F and the normal temperature is 3.2 degrees ​F, what is the variation from the normal​ temperature?

Answers

Answer:

-7.8

Step-by-step explanation:

We will substitute the recorded temperature (-4.6) in the “R” (in the formula) and we will substitute 3.2 in the normal temperature “N”. So you should have V= -4.6 - 3.2 (negative Four point six subtracted by three point two) then solve. This should give you -7.8. Remember your integers!
