Answer:

1.  x < -4 or x ≥ 3

2.  -2 <  x ≤  3<em> </em>

Step-by-step explanation:

1. 5x - 5 ≥ 10

5x ≥ 15

x ≥ 3

-3x + 1 > 13

-3x > 12

x < -4

Solution is       x < -4 or x ≥ 3


2. 5x + 3 ≤ 18

5x ≤ 15

x ≤ 3

4 - x < 6

-x < 2

x > - 2

answer is   -2 < x ≤  3

I need help with the numbers 9 and 10 please help
Katen [24]
9] Rocky Falls would be 13.4°F at sunrise.

Use the equation 23.1 + (-9.7) = x, where x is the temperature at sunrise (13.4)
23.1 + (-9.7) = 23.1 - 9.7
Solve so that x = 13.4

10] Jamie originally had $263.25 in her account.

Just add how much she spent (135.75 + 32) to how much she ended up with (95.5)

135.75 + 95.5 + 32 = 263.25


If you are asking how much she has if she started out with $95.50 before going to the Mets game,

95.5 - (135.75 + 32) = -$72.25
Or 95.5 - 135.75 - 32, same result of -72.25

Write the equation of a line that passes through two points (-1, 0) and (4, -5).
sleet_krkn [62]

Answer:

<u>y = -1 (x) -1</u>

Step-by-step explanation:

If you plug in the numbers from the coordinates into the equation, you will find that it's true.

-1 is x and 0 is y. Plug in the #s like so:

y = -1 (x) -1

0 = -1 (-1) - 1

0 = 1 - 1

0 = 0

Therefore, the equation above represents the line that passes through both these points.
