c. 83 points

Step-by-step explanation:

Answer:

Alright, lets get started.

Angle 3 and angle 4 are adjacent angles because they are having the common side.

They both are on straight line, so, their addition will be 180°.

Suppose angle 4 is x , hence

angle 4 + angle 3 = 180

Subtracting 89 from both sides

°

Hence angle 4 is 91°. : Answer

Hope it will help :)

Answer:

(-infinity,+infinity)

Step-by-step explanation:

Domain refers to the x-axis. So if we look from left to right along the x-axis we could conclude that the function will go infinitley from negative infinite to positive infinity.

Answer:

15 inches

Step-by-step explanation:

Substitute the formula

Let 'x' be the other side

2 [ l + b ] = Perimeter

2 [ 12 + x ] = 58

    12 + x   = 58 divided by 2

           x    = 27 - 12

                 = 15

Therefore 15 inches is the other side.

Answer:  5(11m + 6)

Step-by-step explanation:

We find the Greatest common factors to factor out:

55m + 30

= 5(11m + 6)

Answer:

n ≤ 6

Step-by-step explanation:

Representing the number of goldfish that can live in a small tank as n, we can express this constraint as

n ≤ 6

Answer:

g_<_6

Step-by-step explanation:

Answer:

Sure.

Step-by-step explanation:

So X is a variable meaning its a letter that represents a number. When there are a number and a variable (or a letter) like this 2x or 9y it means you are going to multiply the number by the variable. In this case it is 7 times x is equal to 21 so all we have to do is find what times 7 is equal to 21 and that number is 3. So if 7*x=21 is 7*3=21 then x=3. If you have any questions ill be more than open to answering them, hopefully this helped. Have a good day/night.

ok so here is some help:

Point: any singular location on the line. (basically the dots with letters)

line segment: connects any two points on a given line. Is named using the two points. (LM and MN are two line segments)

rays: a line that is only infinite in one direction. it has a point on one end and the other has to have an arrow on its side. (an example is MN)

Name the line: a line can be named using any two points on a line.

draw a ↔ over line names, --> over rays, and a -- over line segments

Answer:

  x = 1 or 5

Step-by-step explanation:

The notion of "cross-multiplying" is the idea that the numerator on the left is multiplied by the denominator on the right, and the numerator on the right is multiplied by the denominator on the left. This looks like ...

  [tex]\displaystyle \frac{x-1}{7}=\frac{2x-2}{3x-1}\ \longrightarrow\ (x-1)(3x-1)=(7)(2x-2)[/tex]

Then the solution proceeds by eliminating parentheses, and solving the resulting quadratic equation.

  [tex]3x^2-4x+1=14x-14\\\\3x^2-18x+15=0\qquad\text{subtract $14x-14$}\\\\x^2-6x+5=0 \qquad\text{divide by 3}\\\\(x-1)(x-5)=0\qquad\text{factor}\\\\x\in\{1,5\}[/tex]

Comment on "cross multiply"

Like a lot of instructions in Algebra courses, the idea of "cross multiply" describes what the result looks like. It doesn't adequately describe how you get there. The one and only rule in solving Algebra problems is "whatever is done to one side of the equation must also be done to the other side of the equation." If you multiply one side by one thing and the other side by a different thing, you are violating this rule.

What looks like "cross multiply" is really "multiply by the product of the denominators and cancel like terms from numerator and denominator." Here's what that looks like with the intermediate steps added.

  [tex]\displaystyle \frac{x-1}{7}=\frac{2x-2}{3x-1}\\\\\frac{x-1}{7}\times7(3x-1)=\frac{2x-2}{3x-1}\times7(3x-1)\\\\(x-1)(3x-1)=(2x-2)(7)\qquad\textit{looks like}\text{ cross multiply}[/tex]

6.1 - 51.4 = -45.14

But if 51 went first

51.24 - 6.1 = 45.3

Answer:

The solution to the graph are x = -2 and x = 2

Step-by-step explanation:

Here, we want to get the solution to the graph

As we can see, the graph is parabolic; which is a property of a quadratic polynomial

The solution refers to the value at which the graph plot crosses the x-axis

In other words, the solutions to the graph are represented by the point at which we have the graph crossing over the x-axis

We can see this happen at two points

These are the points x = -2 and x = 2

Answer: 101000

Step-by-step explanation: It would be rounded to 101000 because the nearest 100 would be a 1000.

Answer: 111,000 because when you round 994 you get a thousand because that’s the next hundred so you get 111,000

Answer:

Three gallons will be enough to make 128 servings.

Step-by-step explanation:

In Three gallons there are 64 cups. if 5 cups makes 10 servings, that is 1/2 cup per serving. So 64 cups will make 128 servings.
