Answer:
16 points
Step-by-step explanation:
You are given ...
second = first - 4
second = 12
Substituting the second equation into the first, we have ...
12 = first - 4
16 = first . . . . . . . . add 4 to both sides
Ethan scored 16 points in the first game.

Answer:
(f × g)(x) = 3x^3 - 14x^2 -27x + 18
Step-by-step explanation:
That is f(x) × g(x). You have to multiply them as separate polynomials.
(f × g)(x) = (3x^2 + 4x - 3)(x - 6)
Use the foil method.
(f × g)(x) = 3x^3 - 18x^2 + 4x^2 - 24x - 3x + 18
Finally, simplify.
(f × g)(x) = 3x^3 - 14x^2 - 27x + 18
Do the lines given by the equations below intersect at the point (4,-6)? Explain why or why not.
2x - y = 14
x - 3y = 22
A. No, (4, -6) is not a point of intersection because it is not a solution to x - 3y = 22.
B. Yes, (4, -6) is a point of intersection because it is a solution to both equations.
C. No, (4 ,-6) is not a point of intersection because it is not a solution to 2x - y = 14.
D. No, (4, -6) is not a point of intersection because it is not a solution to either equations.
Answer:
B. Yes, (4, -6) is a point of intersection because it is a solution to both equations.
Step-by-step explanation:
In order to find if a certain point exists on a line or not, we can simply substitute in the values, and see if the result is valid. Here we are given the point (4,-6), this means our x=4 and our y=-6. If this point lies on a line, then substituting in the values should result in a valid equation. Let's try the first one:
2x-y=14
2(4)-(-6)=14
8+6=14
14=14
This equation is valid which means the point (4,-6) is indeed a point on the first given line equation.
Now for the second one:
x-3y=22
(4)-3(-6)=22
4+18=22
22=22
This is also a valid equation meaning the point (4,-6) also exists on the second line equation. Since this point exists on both lines, they will intersect each other on a graph. Therefore the best answer here is B. Yes, (4, -6) is a point of intersection because it is a solution to both equations.
Hope this helped!

each bus have to make to get everyone to the stadium?
If the sum of 8 and 5x is 11, what is the value of 2x?
Please explain the steps.
Answer:
2x = 1.6 as decimal
2x = 6/5 as fraction.
Step-by-step explanation:
Okay so just write it as an equation.
5x + 8 = 11 (minus 8 on both sides)
5x = 3 (divide by 5)
x = .6 or 3/5
NOW if you want to find what 2x equals. We already know what x equal so just multiply x by 2.
x = .6 (multiply by 2 on each side)
2x = 1.2 or
2x = 6/5

Step-by-step explanation:
Statement 4(6x+1) +4 =104 reason ?
Answer:
x = 4
Step-by-step explanation:
4(6x+1) +4 =104
-4 -4
4(6x+1) = 100
distribute
24x + 4 = 100
-4 -4
24x = 96
x = 4
To check your work, substitute the x value into the equation.
4(6(4)+1) +4 =104
4(25) + 4 = 104
104 = 104
It is correct, one solution.

What is the equation of the line?
A. y=2x+2
B. y=2x-4 C.
y=1/2x+2
D. y=1/2x-4
Answer:
The equation for the line that is shown is: Answer choice C.
[tex]y =\frac{1}{2}x+2[/tex]
Step-by-step explanation:
From what I can see, there is several clues that can lead us to our answer by just looking at the graph:
y - interceptWhether if the slope is positive or negativeA. Your y - intercept is where your line crosses at a point on the y - axis, so your y - intercept is:
y - intercept = 2If you do not know, the y - intercept form in slope - intercept form is the 'b' value:
[tex]y = mx + b[/tex]
[tex]b =[/tex] y - intercept
[tex]mx =[/tex] slope (m is actually the letter that represents it, but thought I might include x in it to show you from the formula)
Now that you have found your 'b' value, you can eliminate several answer choices: Answer choice B. and D.
B. Now we will see if the slope is positive or negative.
To find out whether it is positive or negative, we would have to take a look at the direction of the line, in this case, the line is going upwards to the right, meaning the slope is positive.
C. Now to find the slope:
To do this we must know the fraction like form of a slope, this would be:
(m = slope)
To determine the slope, m, it is [tex]\frac{RISE}{RUN}[/tex]
'Rise' meaning the y point and 'run' being the x point
In this case:
the line rises up 1 and runs over 2
so, m = [tex]\frac{1}{2}[/tex]
Your final answer will be:
[tex]y =\frac{1}{2}x+2[/tex]

10x-15=6x-43
Is this Infinitely Many Solutions
One Solutions
Or No solution
Answer:
one solution
Step-by-step explanation:
Given
10x - 15 = 6x - 43 ( subtract 6x from both sides )
4x - 15 = - 43 ( add 15 to both sides )
4x = - 28 ( divide both sides by 4 )
x = - 7 ← one solution

Given the function f(x) = 4ˣ
evaluate f (1)
Answer:
4
Step-by-step explanation:
Any base raised to the power of 1 is that base.
f(x) = 4^x
f(1) = 4^1 = 4
Answer:
I think it is 4 (correct me if I'm wrong)
Step-by-step explanation:
the answer is 4 because the the f(1)
this means that the (x) is replaced by f(1)
then you see the 4^{x} is replaced by 4^{1}
4^{1} = 4

Clara has 8 sponsors for the charity walk. Upton has 12 sponsors. Which statement comparing the number of sponsors Clara and Upton each have is accurate?
Clara has 4 times as many sponsors as Upton.
Clara has 4 more sponsors than Upton.
Upton has 4 times as many sponsors as Clara.
Upton has 4 more sponsors than Clara.
Upton has 4 more sponsors than Clara.
If Upton has 12 sponsors and Clara has 8, Clara cannot have more than Upton so times is not an option. Upton only has 4 more and not times than Clara.
the answer will be 180
