Answer:

X = -1 or X = -3.5

Step-by-step explanation:

2x^2 + 9x + 7 = 0

ac = 14

b = 9

find a two numbers which when you multiply you get 14 and add you get 9.

so it will 2 and 7. (they replace b which is 9x)

therefore: 2x^2 + 2x + 7x + 7 = 0

find common factors using each 2 from the four.

2x( x + 1) + 7 (x+1) = 0

so it will be (2x + 7) (x+1) = 0

find x,

i) 2x +7 = 0

x= -3.5

ii) x + 1 = 0

x = -1

Step-by-step explanation:

Leah wants to earn at least 120 dollars a month and she has two job options. This is written as

5x + 8y > 120

She also can't work more than 20 hours, leading us to the second equation

x + y = 20

First we solve for one variable

y = 20 - x

then substitute it into the first equation

5x + 8(20 - x) = 120

Solve for x

5x + 160 - 8x = 120

3x = 40

     x = 40/3

Then we solve for y

y = 20 - x

     y = 20/3

x < 40/3

y > 20/3

B and D will not work because their x+y is greater than 20.

E will also not work because the value is less than 120

Answer:

C) 574.53 foot-pounds

Step-by-step explanation:

got it right on edge :)

Awagon is being pulled by a force of 15 pounds.  the required work done is 574.53 to pull the wagon So, Option C) is correct work done = 574.53.

The work done is product of force and cosine of displacement.

Given; Awagon is being pulled by a force of 15 pounds. We need to find How much work is done in moving the wagon 50 feet if the handle makes an angle of 40° with the ground.

Force = 15 pounds

distance = 50 feet

Ф = 40°

We can calculate the work done as;

work done = force x displacement x cosФ

work done = 15 x 50 x cos40

work done = 15 x 50 x 0.76

work done = 574.53

Therefore, the required work done is 574.53 to pull the wagon.

Answer:

10x + 39 - y

Step-by-step explanation:

Answer:

10x - y +39

Step-by-step explanation:

Answer:

the equation to find the slope is (y2-y1)/(x2-x1)

the points are (-1,2) and (2,2) so plug it in and you get

(2-2)/(2-(-1))

0/ (2+1)

0/3

whenever the numerator is 0, that means the slope is 0. the line is just a horizontal line.

Answer:

a) 4x-8

b) 3y + 27

c) -6 + 2r

Step-by-step explanation:

Here, we want to use the distributive property to evaluate the given expressions

Mathematically, the distributive property is;

(a + b) * c = (a * c) + (b * c)

So we use this on each of our questions;

a) 4(x-2)

= (4 * x) - (4 * 2) = 4x-8

b) 3(y + 9)

= (3 * y) + (3 * 9)

= 3y + 27

c) -2(3-r)

= (-2 * 3) - (-2 * r)

= -6 + 2r

To solve the equation |11x + 10| = 22, we need to consider two cases: one where the expression inside the absolute value is positive and one where it is negative.

Case 1: (11x + 10) is positive:

In this case, the equation becomes 11x + 10 = 22. Solving for x, we subtract 10 from both sides, resulting in 11x = 12. Dividing by 11 gives x = 12/11.

Case 2: (11x + 10) is negative:

Here, the equation becomes -(11x + 10) = 22. Simplifying, we have -11x - 10 = 22. Adding 10 to both sides gives -11x = 32. Dividing by -11 yields x = -32/11.

Thus, the solution set for the given equation is x = 12/11 and x = -32/11, representing the two possible values of x that satisfy the equation |11x + 10| = 22.

Answer:

A. It can be expressed as a non repeating, non terminating decimal.

Step-by-step explanation:

Irrational numbers are numbers with a decimal that goes on forever.

The decimal also never repeats, for the entirety that it goes on.

Since the solution is an irrational number, this means that the solution can be expressed as a non-repeating and non-terminating decimal.

So, A is the correct answer.

Answer:

Step-by-step explanation:

To get 22 with four consecutive integers, we need the integers 4, 5, 6, and 7.

(4 and 5 equal 9, then 9 and 6 equal 15, and 15 and 7 equal 22.)

4 is the smallest of these four, and thus the least of these.
