Answers

Answer 1

Answer: f(-9)= 243

Step-by-step explanation:

f(x) = 4x²+7x -18

f(-9) = 4(-9)²+7(-9)-18

= 4(81) -63-18

= 324- 81

= 243

Staples sells boxes of pens for ($10) and rubber bands for ($24). Leona ordered a total of 24 cartons for $210. How many boxes of each did Leona order? Hint: Let P = Pens.

Answers

Answer:

Leona ordered 19 boxes of pens and 5 rubber bands

Step-by-step explanation:

Let there are p pen and b rubber bands.

ATQ,

p+b = 24 ...(1)

and

10p+4b = 210 ...(2)

Multiply equation (1) by 10.

10p+10b = 240 ...(3)

Subtract equation (2) from (3).

10p+10b-(10p+4b ) = 240-210

6b = 30

b = 5

Put the value of b in equation (1).

p+5 = 24

p = 19

Hence, Leona ordered 19 boxes of pens and 5 rubber bands.

The line m has a slope of 4. What is the slope of a line perpendicular to line m?

Answers

Step-by-step explanation:

Given

Slope (m1) = 4

As it is said that the lines are perpendicular so we have

m1 * m2 = - 1

4 * m2 = - 1

m2 = - 1/4

The slope of the line perpendicular to line m is

- 1/4

Hope it will help :)❤

Answer:

The slope of the perpendicular line is -1/4

Step-by-step explanation:

Perpendicular lines have slopes that multiply to -1

Let the slope of the perpendicular line have sloe p

m*p = -1

4 * p = -1

Divide each side by 4

p = -1/4

The slope of the perpendicular line is -1/4

n-6=2n-n

pls help solve :)

Answers

Answer:eorder the terms:

-6 + n = 2n + -1n

Combine like terms: 2n + -1n = 1n

-6 + n = 1n

Solving

-6 + n = 1n

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '-1n' to each side of the equation.

-6 + n + -1n = 1n + -1n

Combine like terms: n + -1n = 0

-6 + 0 = 1n + -1n

-6 = 1n + -1n

Combine like terms: 1n + -1n = 0

-6 = 0

Add '6' to each side of the equation.

-6 + 6 = 0 + 6

Combine like terms: -6 + 6 = 0

0 = 0 + 6

Combine like terms: 0 + 6 = 6

0 = 6

Simplifying

0 = 6

Combine like terms: 0 + -6 = -6

-6 = 6 + -6

Combine like terms: 6 + -6 = 0

-6 = 0

Step-by-step explanation:

Answer:

-6 = 0n

Step-by-step explanation:

n - 6 = 2n - n

n - 6 = n

-n        -n

-6 = 0n
