Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Given

x² + 3x - 5 - (4x² + 3x - 6) ← distribute parenthesis by - 1

= x² + 3x - 5 - 4x² - 3x + 6 ← collect like terms

= - 3x² + 1 → B

Use the Pythagorean theorem:

70^2 = 42^2 + width^2

4900 = 1764 + width ^2

Subtract 1764 from both sides

3136 = width^2

Take the square root of both sides

Width = 56 inches

Answer:

y = 12  when x = 6/7.

Unless you give a formula (function, or equation) that specifies their relationship, one cannot find x when y equals something else.

Answer:

The midpoint would be (-3, 1)

Step-by-step explanation:

since the formula for midpoint is [tex](\frac{x^{1} +x^{2} }{2}, \frac{y^{1} +y^{2} }{2} )[/tex], you would just have to plug in the coordinates given on the graph. I think your points are (-1, 4) and (-5, -2).

[tex](\frac{-1 -5}{2}, \frac{4-2}{2} )[/tex]

[tex](\frac{-6}{2}, \frac{2}{2} )[/tex]

If you simplify, then you should get (-3, 1)!

Answer:

a = - 1

Step-by-step explanation:

Step 1:

6a + 5a = - 11        Equation

Step 2:

11a = - 11         Combine Like Terms

Step 3:

a = - 11 ÷ 11       Divide

Answer:

a = - 1

Hope This Helps :)

The solution to the equation 6a + 5a = -11 is a = -1.

We have,

To solve the equation 6a + 5a = -11, we can combine the like terms on the left side of the equation and then isolate the variable a.

Step 1: Combine like terms

On the left side, we have 6a + 5a, which gives us 11a. The equation becomes:

11a = -11

Step 2: Isolate the variable

To isolate variable a, we divide both sides of the equation by 11:

(11a) / 11 = (-11) / 11

a = -1

Therefore,

The solution to the equation 6a + 5a = -11 is a = -1.

Answer:

A) x=8 and angle ABC=115 degrees

Step-by-step explanation:

the lines are parallel, meaning the angles are congruent.

you can set up the equation (15x-5)=(10x+35) and simplify.

1. separate variable by subtracting 10x on both sides to get (5x-5)=(35)

2. add 5 on both sides to get 5x=40

3. divide both sides by 5 to get x=8

4. plug x=8 into original function (10x+35) to get (10(8)+35) which equals 115 degrees

Answer:48.6

we know that

You can paint 75 square feet of a surface every 45 minutes

so

using proportion  

Find out how long it takes you to paint a surface area of 81 square feet

45(81)/75=48.6

hope this helped and I hope you get a correct answer :D

Answer:

48.6 minutes

Step-by-step explanation:

First we must identify the area of the given wall :

A = L * W

A = 9 * 9

81 = 9 * 9

[tex]81ft^2[/tex]

Now we know that we can paint 75 square feet every 45 minutes so we must use proportion to find out how long it'll take you.

[tex]\frac{75}{45} *\frac{ft^2}{min}[/tex]

=

[tex]\frac{81}{x}[/tex] [tex]\frac{ft^2}{min}[/tex]

x = 45(81) / 75

x = 3645 / 75

x = 48.6 minutes

Answer:

Wow that's hard to look at. But, when zooming in, we can see that the arrow is closer to 116 degrees, so that is the answer.

Step-by-step explanation:

Notice that the angle/arrows is opening up from right to left, so it will be greater than 90 degrees. The arrow is a little bit more than 115 degrees, so it has to be 116 degrees.

Answer:

False because they are congruent

Step-by-step explanation:

Answer:

1) Infinitely many solutions.

2) No real solutions.

3) (-1, 2)

Step-by-step explanation:

The solutions of a system of linear equations is whenever the two lines intersect.

However, if the two lines never intersect (they are parallel), then there are no solutions.

And if the two lines are the same line, then there are infinitely many solutions.

First Graph:

The two lines are exactly the same.

Hence, there are infinitely many solutions.

Second Graph:

The two lines are parallel. They will never intersect each other.

Therefore, there are no real solutions.

Third Graph:

The two lines intersect at the point (-1, 2).

Hence, there is only one solution and it is (-1, 2).

Answer:

66 gallons

Step-by-step explanation:

Given that initially 160 gallons of a solution containing 12% salt.

So, the initial amount of salt = 12% of 160 = 12/100 x 160 = 19.2 gallons.

Let x gallons of water get evaporated so that the remaining solution contains 20% salt.

The remaining amount of solution = 160-x gallons.

As the initial amount of salt is still in the solution which is equal to 20% of the remaining solution, so

19.2 = 20% of (160-x)

[tex]\Rightarrow 19.2 = \frac {20}{100}\times (160-x) \\\\\Rightarrow 19.2 = \frac {1}{5}\times (160-x) \\\\\Rightarrow 19.2 \times 5= 160-x \\\\\Rightarrow 96= 160-x \\\\\Rightarrow x= 160-96 \\\\[/tex]

[tex]\Rightarrow x= 66[/tex] gallons

Hence, 66 gallons of water must be evaporated to get a 20% salt solution.
