Answer:

y = -5x + 8

Step-by-step explanation:

Equation of a line: y = mx + b

x = slope

b = y-intercept or starting point

Slope = y^2 - y^2/x^2 - x^1

Slope = -12 - 43/4 - (-7)

Slope = -55/11

Slope = -5

b = y - y^1 = m(x - x^1)

b = y - 43 = -5(x - (-7))

b = y - 43 = -5x - 35

Add 43 to both sides

y = -5x + 8

Sharon has some one-dollar bills and some five-dollar bills. She has 14 bills. The value of the bills is $30. Solve a system of
Scorpion4ik [409]

Answer:

10 one-dollar  and 4 five-dollar bills.

Step-by-step explanation:

Let x = the number of one-dollar bills and y = number of five-dollar bills.

Then:

x + y = 14

x + 5y = 30      (using the values of the bills)

Subtracting the 2 equations:-

-4y = -16

y = 4

so x + 4 = 14

x = 10.

There are 10  one-dollar bills and 4  five-dollar bills.

Find the height of when's, 14,494. Round the height to the nearest thousand feet
8_murik_8 [283]
14,494
To round off the height value to the nearest thousand we can use the expanded from to clarity the position of numbers which is:
10, 000 = ten thousand
4, 000 = thousands
400 = hundreds
90 = tens
4 = ones
Here we can notice than four thousand is the value where the nearest thousands is placed. Hence we can round off the number of 14, 494 into 14, 000. Notice 0-4 rounding off rules.

Step-x ≤ 3

Given

2(4 + 2x) ≥ 5x + 5 ← distribute parenthesis on left side

8 + 4x ≥ 5x + 5 ( subtract 4x from both sides )

8 ≥ x + 5 ( subtract 5 from both sides )

3 ≥ x , hence
