Answer:
f = 79
Step-by-step explanation:
1) move 146 to the other side so f = 225 - 146
2) solve and get f = 79
3) check answer by substituting 79 into 146 + f = 225
4) 146 + 79 = 225
Answer:
first subtract 146 to both sides of the equation next simplify the equation to get the solution

Step-by-step explanation:
Easton is a high school basketball player. In a particular game, he made some two point shots and some three point shots. Easton scored a total of 21 points and made twice as many two point shots as three point shots. Write a system of equations that could be used to determine the number of two point shots Easton made and the number of three point shots he made. Define the variables that you use to write the system
Answer:
2+3y=21
x=2y
Step-by-step explanation:
Each two point shot scores 2 points, so xx two point shots would score 2x points. Each three point shot scores 3 points, so y three point shots would score 3y points. Therefore, the total number of points scored 2x+3yy equals 21
Since Easton scored twice as many two point shots as three point shots, he made more two point shots, so if we multiply 2 by the number of three point shots made, we will get the number of two point shots made, meaning x equals 2y

Answer:
7. Slope = -7/4
8. Slope = 2
9. Second Point = (0, 0)
10. Second Point = (0 ,-5)
Step-by-step explanation:
Find the slope: Slope Formula = y2-y1/x2-x1
7. (2, 4) and (6, -3)
x1,x2 = (2, 4) y1,y2 = (6, -3)
(-3 - 4)/(6 - 2)
-7/4
8. (-5, 1) and (-1, 9)
x1,x2 (-5, 1) y1,y2 (-1, 9)
(9 - 1)/(-1 - (-5))
8/4
2
Second Point on Line:
9. We know: slope = 1/2, and (2, 1) is on the line; So:
y = 1/2x + b where we have to still find b
so b = y1 - m * x1
b = 1 - 1/2 * 2
b = 1 - 1
b = (0,0)
If you plug this in to the slope formula, it comes out to 1/2
10. We know: slope = -4, and (-3, 7) is on the line; So
y = -4x + b where we have to still find b
so b = y1 - m * x1
b = 7 - (-4) * -3
b = 7 - 12
b = (0,-5)
If you plug this in to the slope formula, it comes out to -4
Samir is a self-employed marketing consultant. He had no income from January through March 2020. His April through December 2020 income subject to SE tax is $55,000.
Samir's SE tax for 2020 is $7,771 [$55,000 x 0.9235 x 0.153 = $7,771]. Samir may reduce his estimated tax payments by how much?
Answer:
Step-by-step explanation:
Since he is his own boss, he is basically a self employed taxpayer and should be to deduct the employer portion of self employment taxes that he/she pays during the year.
In a case like this, the total self employment taxes are $7,771 x 50% = $7,771 * 0.5 = $3,885.50. This money also now, is corresponding to employer taxes (the other 50% are not deductible since they correspond to employee taxes).
Self employment taxes composes but not limited to Medicare and Social Security taxes (FICA taxes basically).

9. SHOW FULL STEPS. Solve for f(-4) and f(7) of the function below
f(x)=7-2x-3x²
Answer:
f(-4) = 33
f(7) = -154
Step-by-step explanation:
In this question, you will solve the function by plugging in the given value.
Solve:
f(-4) = 7 - 2(-4) -3(-4)²
= 7 - 2(-4) - 48
= 7 + 8 - 48
= 7 - 40
f(-4) = 33
----------------------------------
f(7) = 7 - 2(7) -3(7)²
= 7 - 2(7) - 147
= 7 - 14 - 147
= 7 - 161
f(7) = -154
5 < k -2 < 11 ?
-4 > y + 2 > -10 ?
5 -m < 4 or 7m > 35 ?
3 < 2p -3 < 12 ?
Answer:
[tex]7 < k < 13[/tex]
[tex]-6>y>-12[/tex]
[tex]m > 5[/tex]
[tex]3 < p < \frac{15}{2}[/tex]
Step-by-step explanation:
Given
[tex]5 < k -2 < 11[/tex]
[tex]-4 > y + 2 > -10[/tex]
[tex]5 -m < 4\ or\ 7m > 35[/tex]
[tex]3 < 2p -3 < 12[/tex]
Required
Solve
Solving (1):
[tex]5 < k -2 < 11[/tex]
The above can be represented as:
[tex]5<k -2[/tex] and [tex]k -2<11[/tex]
Solving [tex]5<k -2[/tex]
[tex]5 + 2 <k[/tex]
[tex]7<k[/tex]
Solving [tex]k -2<11[/tex]
[tex]k < 2 + 11[/tex]
[tex]k < 13[/tex]
So, we have:
[tex]7<k[/tex] and [tex]k < 13[/tex]
This can be combined as:
[tex]7 < k < 13[/tex]
Solving (2):
[tex]-4 > y + 2 > -10[/tex]
Split as:
[tex]-4 > y + 2[/tex] and [tex]y + 2 > -10[/tex]
Solving [tex]-4 > y + 2[/tex]
[tex]-4 - 2 > y[/tex]
[tex]-6 > y[/tex]
Solving [tex]y + 2 > -10[/tex]
[tex]y > -10 - 2[/tex]
[tex]y > -12[/tex]
So, we have:
[tex]-6 > y[/tex] and [tex]y > -12[/tex]
This gives
[tex]-6>y>-12[/tex]
Solving (3):
[tex]5 -m < 4\ or\ 7m > 35[/tex]
Solve for m in both cases:
[tex]5 - m < 4[/tex]
[tex]-m<4 - 5[/tex]
[tex]-m<- 1[/tex]
[tex]m > 1[/tex]
[tex]7m > 35[/tex]
Divide both sides by 5
[tex]m > 5[/tex]
So, we have:
[tex]m > 1[/tex] or [tex]m > 5[/tex]
The solution is [tex]m > 5[/tex] because [tex]5> 1[/tex]
Solving (4):
[tex]3 < 2p -3 < 12[/tex]
The above can be represented as:
[tex]3 < 2p - 3[/tex] and [tex]2p - 3<12[/tex]
Solving [tex]3 < 2p - 3[/tex]
Add 3 to both sides
[tex]3 + 3 < 2p - 3 + 3[/tex]
[tex]6 < 2p[/tex]
Divide both sids by 2
[tex]3 < p[/tex]
[tex]2p - 3<12[/tex]
Add 3 to both sides
[tex]2p - 3 + 3 < 12 + 3[/tex]
[tex]2p < 12 + 3[/tex]
[tex]2p < 15[/tex]
Solve for p
[tex]p < \frac{15}{2}[/tex]
So, we have:
[tex]3 < p[/tex] and [tex]p < \frac{15}{2}[/tex]
Combined as:
[tex]3 < p < \frac{15}{2}[/tex]

Step-by-step explanation:
Answer:
2
Step-by-step explanation:
8x - 5x + 4 - x = Ax + 8 ------- start by combining the on the left
(8x - 5x - x) + 4 = Ax + 8 ------- solve
2x + 4 = Ax + 8 ------ A has to be the same # as the variable on th left side
2x + 4 = 2x + 8 ------- now subtract 2x from both sides
4 = 8
Which is the correct answer when solving the equation using
elimination?
1. -4x - 2y = -12
4x + 8y = -24
A. (6,-6) because I was able to eliminate my y terms first
B.(-6,6) because I was able to eliminate my y terms first
C.(6,-6) because I was able to eliminate my x terms first
D.(-6.6) because I was able to eliminate my x terms first
Answer:
We conclude that the correct option is 'A'.
As I was able to get (6, -6) because I was able to eliminate my y terms first.
Step-by-step explanation:
Given the system of equations
[tex]\begin{bmatrix}-4x-2y=-12\\ 4x+8y=-24\end{bmatrix}[/tex]
solving using the elimination method
[tex]4x+8y=-24[/tex]
[tex]+[/tex]
[tex]\underline{-4x-2y=-12}[/tex]
[tex]6y=-36[/tex]
so
[tex]\begin{bmatrix}-4x-2y=-12\\ 6y=-36\end{bmatrix}[/tex]
solve for y
[tex]6y=-36[/tex]
Divide both sides by 6
[tex]\frac{6y}{6}=\frac{-36}{6}[/tex]
[tex]y=-6[/tex]
[tex]\mathrm{For\:}-4x-2y=-12\mathrm{\:plug\:in\:}y=-6[/tex]
[tex]-4x-2\left(-6\right)=-12[/tex]
[tex]-4x+12=-12[/tex]
[tex]-4x=-24[/tex]
Divide both sides by -4
[tex]\frac{-4x}{-4}=\frac{-24}{-4}[/tex]
[tex]x=6[/tex]
Thus, the solutions are:
[tex]x=6,\:y=-6[/tex]
Therefore, we conclude that the correct option is 'A'.
As I was able to get (6, -6) because I was able to eliminate my y terms first.
Question
A fence is in the shape of an isosceles triangle with a base of 61 feet. The perimeter of the fence is 190 feet. How long is
each of the equal sides of the fence?
Provide your answer below:
feet
Answer:
x = 64.5 feet
Step-by-step explanation:
Equations
An isosceles triangle has two sides of the same length and one of different length.
The fence has the shape of an isosceles triangle with a base of 61 feet. The base is the side with a different length.
Call x to the length of each of the equal sides. Since the perimeter is the sum of all three sides, and the perimeter is given as 190 feet, then:
x + x + 61 = 190
Simplifying:
2x + 61 = 190
Subtracting 61:
2x = 190 - 61 = 129
Dividing by 2:
x = 129/2
x = 64.5 feet
Which of the following expressions is in simplified form?
-9+ 2.7x + 0.8
03 w+ 1.3w
62 - 4
02t - 5 - t
Answer:
None of these expressions are in simplified form.
Step-by-step explanation: So basically simplified form is that an equation/expression is till you cant combine any like terms. Liked terms are like 4 and 5 or 2x and 3x.
Number 1_ 2.7x-8.2.
Number 2_ 4.3w. Is the 03 a 3 or 0.3?
Number 3_ 58.
Number 4_ t-5. Is the 02t a 2t or 0.2t?
I hope this helps and please let me know about the questions on Number 2 and 4 that I asked about in the explanation below in the comments. Thanks!

Calculate the average rate of change for the function f(x) = x4 + 3x3 − 5x2 + 2x − 2, from x = −1 to x = 1. A −1 B 1 C −5 D 5
Answer:
D. 5
Step-by-step explanation:
From the information given:
The derivatives of functions and functions have a different average rate. The average rate expanded over an interval of two distinct point (a f(a)) and (b f(b)) is represented by the equation:
[tex]\dfrac{f(b)-f(a)}{b-a}[/tex]
where; the two points are:
(-1 , f( -1) ) & ( 1, f(1) )
For f(1); we have:
f(1) = 1 +3(1)³ - 5(1)² + 2(1) - 2
f(1) = 1 + 3 - 5 + 2 -2
f(1) = - 1
For f( -1); we have:
(-1)⁴ + 3(-1)³ - 5(-1)²+2(-1)-2
= 1 - 3 - 5 -2 - 2
= -11
∴
[tex]=\dfrac{-1-(-11)}{1 - (-1)}[/tex]
[tex]=\dfrac{-1+11}{1 +1}[/tex]
[tex]=\dfrac{10}{2}[/tex]
= 5
