. Write an equation for the line parallel to y = 7x + 11 that contains P(-5, 7).

1 answer:

3 0

A) x – 7 = -7(6y + 5)

x – 7 = -42y + -35

x – 7 + 35 = -42y

x + 28 = -42y

y = (1/42)x – 14/21

c) y – 7 = 7(x + 5)

y – 7 = 7x + 35

y = 7x + 42

b) y – 7 = -7(x + 5)

y – 7 = -7x -35

y = -7x – 28

d) y + 7 = 7(x + 5)

y + 7 = 7x + 35

y = 7x + 28

Felipe made sand art bottles to sell at his school's craft fair. He wanted to use 9 different colors of sand. So, he bought 1 po

Dennis_Churaev [7]

Answer: Felipe made 24 sand art bottles.

Step-by-step explanation:

Given: Total different colors of sand = 9

Weight of each color sand = 1 pound

Then, the weight of all 9 colors would be 9 × 1 = 9 pounds

Since 1 pound = 16 ounces

Then, 9 pounds = 9 × 16 = 144 ounces

capacity of each bottle = 6 ounce

Then, the number of bottles required = ( 144 ounces) ÷ 6

= 24

Hence, Felipe made 24 sand art bottles.

Solve for u. 20 − (u · 0.9) = 4.7

alina1380 [7]

Answer:

20 - 0.9u = 4.7

-0.9u = 4.7 - 20

-0.9u = -15.3

Divide both sides by - 0.9

u = 17

Hope this helps.

Help me with these 3 and explain too thank you :))

xz_007 [3.2K]

Answer:

1) 25

2) 2

3) f(g(1)) = 42

Step-by-step explanation:

1) Given that f(x) = 4x^2 + 9

If x = -2

f(-2) = 4(-2)^2 + 9

f(-2) = 4(4) + 9

f(-2) = 16 + 9

f(-2) = 25

2) Given that f(x) = 4x - 6

y = 4x - 6

Replace y with x

x = 4y - 6

MAke y the subject of the forfmula

4y = x+ 6

y = (x+6)/4

SInce x = 2

f^(-1)(2) = (2+6)/4

f^(-1)(2) = 8/4 = 2

3) If f(x) = 6x and g(x) = x+6

f(g(x)) = f(x+6)

f(x+6) = 6(x+6)

Since x = 1

f(g(1)) = 6(1+6)

f(g(1)) = 6(7)

f(g(1)) = 42

What is 380.5 rounded to the nearest whole number

Lisa [10]

Answer:

It will be 381. You round up if it is five and over, and round down if 5 and below.

Step-by-step explanation:

A decimal cannot be a whole number so rounding to the nearest whole number means getting rid of the decimal. You do this by rounding up if it 5 and up, and rounding down if it is 5 and below. 380.5 means you would round up to 381. If it it were 380.4, you would round down to 380.
