Solve for x
Answer:
x = 21
Step-by-step explanation:
5x + 15 = 2x + 78
3x = 63
x = 21
Answer:
x = 21°
Step-by-step explanation:
As corresponding angles in parallel lines are equal,
5x + 15 = 2x + 78
And now let us solve for x.
5x + 15 = 2x + 78
5x + 15 - 2x = 78
3x + 15 = 78
3x = 78 - 15
3x = 63
Divide both sides by 3.
x = 21°
Find the radius of a circle with an area of 89 square feet.

Answer:
149 Degrees
Step-by-step explanation:
The angle 31 is marked for you on the figure, there is also a secondary angle marked on the other line parallel to the first. Since they are marked the same, the value of both must be 31 degrees, you can also prove this in a longer method by calculating the exact angle measures of each line. Now we simply simplify our basic equation.
180-31=x

Write the slope-intercept form of equation.
1) 3x – 2y = -12
Answer:
[tex]y=\dfrac{3}{2}x+6[/tex]
Step-by-step explanation:
Slope-intercept form of a linear equation:
[tex]y=mx+b[/tex]
where:
m is the slopeb is the y-interceptGiven equation:
[tex]3x-2y=-12[/tex]
To write the given equation in slope-intercept form, apply arithmetic operations to isolate the variable y.
Add 2y to both sides:
[tex]\implies 3x-2y+2y=-12+2y[/tex]
[tex]\implies 3x=2y-12[/tex]
Add 12 to both sides:
[tex]\implies 3x+12=2y-12+12[/tex]
[tex]\implies 3x+12=2y[/tex]
Switch sides:
[tex]\implies 2y=3x+12[/tex]
Divide both sides by 2:
[tex]\implies \dfrac{2y}{2}=\dfrac{3x+12}{2}[/tex]
[tex]\implies \dfrac{2y}{2}=\dfrac{3x}{2}+\dfrac{12}{2}[/tex]
[tex]\implies y=\dfrac{3}{2}x+6[/tex]
Therefore, the slope-intercept form of the given equation is:
[tex]y=\dfrac{3}{2}x+6[/tex]
where 3/2 is the slope, and 6 is the y-intercept

We will use the steps that can be used to eliminate the a term that will be -4(a+b=6). Option C is correct.
What is the system of two equations?A set of two linear equations with two variables is called a system of linear equations. They create a system of linear equations when evaluated collectively.
The given equation in the problem is;
Equation P: a + b = 6
Equation Q: 4a + 2b = 19
To cancel out the equation q from the equation p.In order to cancel, the term of we has to multiply the term -4 in the equation p.
Hence we will use the steps that can be used to eliminate the a term that will be -4(a+b=6). Option C is correct.

If A=3x^2 + 5x -6 and B= -2x^2 - 6x +7, then A-B equals ?
Answer:
5x^2 + 11x - 13 = A - B
Step-by-step explanation:
A - B = ? Substitute 3x^2 + 5x - 6 for A and - (-2x^2 - 6x + 7) for -B:
3x^2 + 5x - 6 - (-2x^2 - 6x + 7). or
3x^2 + 5x - 6 + 2x^2 + 6x - 7, or (after combining like terms):
5x^2 + 11x - 13 = A - B

the graph of g(x) is shifted vertically...
The graph ig g(x) si shifted horizontally
Answer:
Its shifted verticlly 2 and to the left 2.
Step-by-step explanation:
Its verticlly because when it says 2^x its going up if it said -2^x it would go down.
It goes left because it is 2^x=? so if you put it on the other side its negative which makes it to the left.

Answer:
60°
Step-by-step explanation:
The given 60° angle and angle 2 are alternate interior angles of parallel lines p and q with transversal s, so they are congruent.
m<2 = 60°
Answer:
Based on the alternate interior angle theorem, the measure of angle 2 in the diagram given is: C. 60°
What is the Alternate Interior Angles Theorem?
The alternate interior angle theorem states that the measure of two alternate interior angles are congruent.
Angle 2 and 60° are alternate interior angles, therefore:

Solve the equation:
Answer :x = 1 ✅
Explanations:x + 2 = 5x - 2
>> Add 2 to both sides
x + 2 + 2 = 5x - 2 + 2
x + 4 = 5x
>> Substract x from each side
x + 4 - x = 5x - x
4 = 4x
4x = 4

-4K2 – 8k – 3 =-3 – 5K2
Solve by factoring
Answer:
k = 0 or 8
Step-by-step explanation:
First, get the variables and constants on their side.
-4k^2 + 5k^2 - 8k = -3 + 3 Now simplify
k^2 - 8k = 0 Factor
k(k - 8) = 0 Solve
k = [0, 8]
If you want you can double check your answer by plugging in the values you got. First, 0.
0 - 0 - 3 = -3 - 0
-3 = -3. That works, so we know 0 is correct. Now 8
-4(64) - 8(8) - 3 = -3 - 5(64)
-256 - 64 - 3 = -3 - 320
-320 - 3 = -323
-323 = -323 That also works, so we know 8 is correct.

They surveyed 100 of their male customers living in California between the ages of 25 and 40. The Golf Federation and found that the most popular golf ball is Miller followed by Smith and Sixon. Therefore, the Golf Federation concludes that the most popular brand of golf balls among men living in the United States between the ages of 25 and 40 is Miller. Select the statement that is true about Golf Federation's conclusion. A. The Golf Federation's conclusion was not valid because the sample was biased since all the male customers were of ages from 25 and 40. B. The Golf Federation's conclusion was not valid because the sample was biased since the male customers all lived in California. C. The Golf Federation's conclusion was valid because the sample was random. D. The Golf Federation's conclusion was valid because the sample was biased since the male customers all lived in California.
Using sampling concepts, it is found that the correct option is given by:
B. The Golf Federation's conclusion was not valid because the sample was biased since the male customers all lived in California.
What is sampling?It is a common statistics practice, when we want to study something from a population, we find a sample of this population, which is a group containing elements of a population. A sample has to be representative of the population, that is, it has to involve all segments of the population.
In this problem, the objective is to make an estimate about the most popular brand of golf ball from men all over the United States, however, only customers from California were chosen, hence the sample is not representative and option B is correct.
