Answer:
C
Step-by-step explanation:
To convert from point-slope form to slope-intercept form, we can simplify and isolate the y.
We have the equation:
[tex]\displaystyle y-3=\frac{1}{2}(x-1)[/tex]
Distribute the right-hand side:
[tex]\displaystyle y-3=\frac{1}{2}x-\frac{1}{2}[/tex]
Add 3 to both sides:
[tex]\begin{aligned} \displaystyle y&=\frac{1}{2}x-\frac{1}{2}+3\\\\&=\frac{1}{2}x-\frac{1}{2}+\frac{6}{2}\\\\&=\frac{1}{2}x+\frac{5}{2}\end{aligned}[/tex]
Our answer is C.

Let's solve your equation step-by-step.
5m−2(m+3)+6/2
=3m−4/2
Step 1: Simplify both sides of the equation.
5m−2(m+3)+6/2
=3m−4/2
5m+(−2)(m)+(−2)(3)+6/2
=3m+−2(Distribute)
5m+−2m+−6+3=3m+−2
(5m+−2m)+(−6+3)=3m−2(Combine Like Terms)
3m+−3=3m−2
3m−3=3m−2
Step 2: Subtract 3m from both sides.
3m−3−3m=3m−2−3m
−3=−2
Step 3: Add 3 to both sides.

As a salesperson at Trading Cards Unlimited, Justin receives a monthly base pay plus commission on all that he sells. If he sells $500 worth of merchandise in one month, he is paid $410. If he sells $900 of merchandise in one month, he is paid $498.
Answer:
Justin's salary will be $1048 when he sells $3400 worth of merchandise.
Step-by-step explanation:
If the salesperson receives a monthly base pay and the commission on the sales expression that represents his monthly pay,
y = B + C(x)
Here y = Monthly pay
B = Base pay
C = percentage of commission
x = Amount of sales done
If he sells $500 worth of merchandise in a month, he earns $410,
410 = B + C(500) -----(1)
If he sells $900 worth of merchandise in a month, he earns $498,
498 = B + C(900) ------(2)
By subtracting equation (1) from equation (2),
498 - 410 = 900C - 500C
88 = 400C
C = [tex]\frac{88}{400}[/tex]
C = 0.22
From equation (1),
410 = B + 0.22(500)
B = 410 - 110
B = $300
Therefore, expression for the monthly earning will be,
y = 300 + 0.22(x)
Justin's salary when he sells $3400 worth of merchandise in a month,
y = 300 + 0.22(3400)
y = 300 + 748
y = $1048
Therefore, Justin's salary will be $1048.

13. Find the roots of the quadratic equation by using the quadratic formula and factorization method (i) x 2 – + 10 = 0
Answer:
x = 5 or -2
Step-by-step explanation:
The general quadratic formula is expressed as;
ax²+bx+c = 0
Given
x² - 3x -10 = 0
a = 1, b = -3 and c = -10
x = -(-3)±√(-3)²-4(1)(-10)/2(1)
x = 3±√9+40/2
x = 3±√49/2
x = 3±7/2
x = 3+7/2 or 3-7/2
x = 10/2 or -4/2
x = 5 or -2
By Factorization
x² - 3x -10 = 0
x² - 5x+2x -10 = 0
x(x-5)+2(x-5) = 0
(x-5)(x+2) =0
x - 5 =0 and x+2 = 0
x = 5 or -2
Omar grouped the terms and factored the GCF out of the groups of the polynomial 3x3 – 15x2 – 4x + 20. His work is shown.
Step 1: (3x3 – 15x2) + (–4x + 20)
Step 2: 3x2(x – 5) + 4(–x + 5)
Omar noticed that he does not have a common factor. Which accurately describes what Omar should do next?
Omar should realize that his work shows that the polynomial is prime.
Omar should go back and regroup the terms in Step 1 as (3x3 – 15x2) – (4x + 20).
In Step 2, Omar should factor only out of the first expression.
Omar should factor out a negative from one of the groups so the binomials will be the same.
Answer:
2nd option
Step-by-step explanation:
Given
3x³ - 15x² - 4x + 20
step 1 ( group the first/second and third/fourth terms )
(3x³ - 15x² ) + (- 4x + 20)
step 2 ( factor each group )
3x² (x - 5) - 4(x - 5) ← note factor of - 4 ( not + 4 )
step 3 ( factor out (x - 5) from each term )
(x - 5)(3x² - 4)

What is the formula or equation for this problem I don’t understand
Answer:
B
Step-by-step explanation:
From the property of parallelogram the opposite angels are equal so < DAB = < DCB so < DAB will become 16x.
9x + 5 + 16x(<DAB) = 180 ....... because it is straight line.
25x + 5 = 180
25x = 180 - 5
25x = 175
x = 7 (it's 7 because u divide 175 by 25)
now let's substitute in the angle < DCB( 16x):-16 × 7= 112
To get < ABC lets use the property of parallelogram which says tha adjacent angles are supplementary. which means <ABC + <DCB = 180
<ABC + 112 = 180
< ABC = 180 - 112
< ABC = 68

A recent study asked the same 15 students their favorite subject at three different times: in elementary school, in middle school, and when getting ready to graduate from high school.
What percentage of students said that Math was their favorite subject in elementary school?
What is the percent of change for History being the favorite subject between elementary school and graduating from high school?
Answer:
53 1/3% for the first answer, and 33 1/3% increase for the second answer
Step-by-step explanation:
Ok, lets start up witht eh first question.
We need to find the percentage of studens that find math the be their favorite subject in elementary school.
We know that there are 15 kids in total.
We specificly see that 8 of those kids like math the most.
To find percentage, divide 8 by 15.
Using a calculator you should find 53 1/3% of the students found math to be their favorite subject.
Next we need to find the percentag eof change that history is over elementary school to high school.
This might sound confusing, but this is basically just a change of 3 students to 4 students.
To find percentage, just divide 3 by 4:
This gets you 33 1/3%

Answer:
A. 693
Step-by-step explanation:
The question is asking you to input 7 into both functions and then multiply them together.
First insert 7 into f(x) = 7 + 2x, 7 times 2 is 14, plus 7 = 21
do the same with g(x) = 5x - 2, 5 times 7 is 35, minus 2 = 33
fg(7) is saying to multiply fg together as a variable next to another variable does. leaving the answer as 693.

(-5 , 2) here -5 is x coordinate and 2 is y coordinate since x coordinate is negative and y coordinate is positive it lies in II quadrant.
(2 , -5) here 2 is x coordinate whereas -5 is y coordinate and siince x coordiante is positive and y coordinate is negative it lies in IV quadrant.
(x^3 - 2)(x^2 + 11)
to find the degree of polynomial first u need to factor this out
x^3(x^2 + 11) -2(x^2 + 11)
x^3 * x^2 + x^3 * 11 - 2 * x^2 - 2 * 11
x^3+2 + 11x^3 - 2x^2 - 22
x^5 + 11x^3 - 2x^2 - 22
since the highest degree is 5 the degree of the polynomial is also 5.

Find the value of x to the nearest tenth. A. 26.3 B. 5.7 C. 9 D. 8.6
Answer:
C
Step-by-step explanation:
you have the angle, adjacent and you want to find the hypotenuse
therefore use CAH - (I drew the triangle on the bottom of the attachment )
length of A / cos(angle) = hypotenuse
7 / cos(39)=9.007
Answer:
C: 9 to the nearest tenth
Step-by-step explanation:
You have three choices on your calculator to solve this problem. Only 1 of the three will work.
Sin(39)
Tan(39)
Cos(39)
You want the hypotenuse (x) and you are given the adjacent side. The adjacent side is the other side that makes up the reference angle other than the hypotenuse.
Cos(theta) = adjacent side / hypotenuse. The is the function you use.
Adjacent side = 7
Cos(39) = 7 / x Multiply both sides by x
x * Cos(39) = 7 Divide by Cos(39)
x = 7 / Cos(39)
x = 9 Isn't that neat? It is actually 9.0073. but C is the answer.
