they will both have to intersect since you have a negative and positive number. Hope it helps.
Step-by-step explanation:
The functions will intersect at y = -2 and y = 1. Option B is correct.
What are functions?Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
The solutions to the equation f(x) = g(x) are -2 and 1.
Solution of the equation state the definition that, when two functions intersect each other, is the solution of the functions. So as mentioned both functions as f(x) = g(x) gives y = -2 and y = 1, implying that The functions will intersect at y = -2 and y = 1.

Which set of ordered pairs does not represent a function?
O {(4,4), (3, -8), (7,-6), (-5, -3)}
o {(-6,6), (8, 2), (8, -1), (3,3)}
o {(-4,-6), (-9, -7), (6, 7), (0, -6)}
o {(9, 5), (-5, -5), (0, 9), (8,3)}
Answer:
The second choices is the answer
{(-6,6), (8, 2), (8, -1), (3,3)} as you can see there's a repeating value of x or the Domain which is the 8.

The sum of a whole number and twice the square of the number is 10. Find the number
Answer:
Hey there !
Solution:
Let the number be x
=> x + 2x² = 10
=> 2x² + x - 10 = 0
Factorising the quadratic equation we get,
=> 2x² + 5x - 4x - 10 = 0
=> x ( 2x + 5 ) -2 ( 2x + 5 ) = 0
=> ( x - 2 ) ( 2x + 5 ) = 0
=> x = 2, -5/2
Since x is a whole number, -5 / 2 wont be applicable.
Hence x = 2.
Hence the number is 2.

Vanessa works 32 hours per week at her job. Her boss offers her a full time job (40 Hours per week) and a 2 dollar per hour raise. She says "this is great now I'll make 200 more per week". What is Vanessa's hourly wage before the raise?
Answer:
$35.75 per hour
Step-by-step explanation:
In order to calculate this, we first need to calculate how much she made with her current hourly wage. We do this by multiplying the hours she worked by her current hourly wage plus her raise.
32 hours * (40+2) = $1,344
Now we subtract $200, since this is how much more she is making with her raise, and then we divide that amount by the 32 hours she is working per week.
(1,344 - 200) / 32 = $35.75 per hour
Finally, we can see that Vanessa's hourly wage before the raise was $35.75 per hour

What is the value of x
HELP!!!!
Answer: 7
Step-by-step explanation: This is an equalateral triangle. You can tell by the marks on each angle, marking that they are equal.
This means that the two sides that aren't the hypotenuse are the same.
Therefore,
[tex]4(x+2) = 36[/tex]
Multiply out the 4
[tex]4x + 8 = 36[/tex]
Subtract 8
[tex]4x = 28[/tex]
Divide by 4
[tex]x = 7[/tex]
for questions 10-11 if l || m, find the values of x and y.
Answer:
10) 9x - 2° = 5x + 54° (corresponding angles are equal)
9x - 5x = 54 + 2
4x = 56
x = 56/4
x = 14°
10y + 6° = 9x - 2° (linear pair)
10y + 6° = 9(14)° - 2°
10y + 6° = 126° - 2°
10y + 6° = 124°
10y = 124° - 6°
10y = 118
y = 118/10

What is the midpoint of the line segment with endpoints (-2,-4) and (4,6)?
A. (-6,10)
B. (-3,5)
C. (1,1)
D. (2.2)
E. (3,5)
Answer:
Answer: C. (1,1)
Step-by-step explanation:
Midpoint
Given a segment defined by points (x1,y1) and (x2,y2), the midpoint (xm,ym) is calculated as follows:
[tex]\displaystyle x_m=\frac{x_1+x_2}{2}[/tex]
[tex]\displaystyle y_m=\frac{y_1+y_2}{2}[/tex]
The endpoints are (-2,-4) and (4,6).
Calculating the midpoint:
[tex]\displaystyle x_m=\frac{-2+4}{2}=\frac{2}{2}=1[/tex]
[tex]\displaystyle y_m=\frac{-4+6}{2}=\frac{2}{2}=1[/tex]
The midpoint is (1,1).
Answer: C. (1,1)

WILL GIVE BRAINLIEST find the value of r (-4,8), (r,12), m=4/3 (show your work pls)
Answer:
r = 13
Step-by-step explanation:
The first step is to find b from y=mx=b using m=4/3 and (-4,8)
[tex]8=\frac{4}{3}(-4)+b[/tex]
After solving the equation, b will equal -16/3 making the final equation be
[tex]y=\frac{4}{3} x-\frac{16}{3}[/tex]
Using the equation, you can solve for r.
[tex]12=\frac{4}{3} x-\frac{16}{3}[/tex]
This will bring the answer being r = 13
Sabrina has 2/4 of a pizza and wants to share it equally between her and kayla.How much of the pizza does each person get?
Answer:
1/4 of the pizza.
Step-by-step explanation:
Since there are 2 people, you would want to divide 2/4 by 2. 2/4*1/2 = 1/4, so your answer is 1/4.
Mrs. Allen a high school teacht is grading quizzes and tests this weekend she has at most 4 hours or 240 minutes to spend grading and she would like to get at least 60 quizzes and tests graded on average it takes her 3 minutes to grade each quiz and 8 minutes to grade each test
Answer:
(55,9)
Step-by-step explanation:
Write one inequality to represent the number of quizzes and tests Mrs. Allen must grade and one inequality to represent the number of minutes it will take her to grade the quizzes and tests.
Mrs. Allen must grade at least 60 quizzes and tests, so the sum of x and y must be greater than or equal to 60.
On average, it takes Mrs. Allen 3 minutes to grade each quiz and 8 minutes to grade each test. So, the total number of minutes it takes her to grade x quizzes is 3x minutes, and the total number of minutes it takes her to grade y tests is 8y minutes. Since she has at most 240 minutes to spend grading, the sum of 3x and 8y must be less than or equal to 240.
The solution set to the system of these linear inequalities represents the numbers of quizzes and tests Mrs. Allen can grade this weekend.
Now, consider each of the coordinate points. In order to be a solution to this system of inequalities, both inequalities must be satisfied by the values of x and y. When x = 55 and y = 9, both inequalities are satisfied. To confirm, substitute these values of x and y into the first inequality.
Now substitute the values into the second inequality.
Therefore, the only point that lies in the solution set is (55,9).
If a 30 foot ladder is positioned so that the bottom of the ladder is 1/4 of its length away from the wall, what angle does the ladder make with the ground
Answer:
[tex]75.52^\circ[/tex]
Step-by-step explanation:
Given that:
The length of the ladder = 30 ft
Distance between bottom of ladder and wall = [tex]\frac{1}{4}^{th}[/tex] of its length
To find:
Angle made between the ladder and ground = ?
Solution:
This situation can be compared with a right angled [tex]\triangle ABC[/tex] as shown in the attached image in the answer area.
Side AC being the hypotenuse has the ladder along it.
AB is the wall.
BC is the distance between the wall and foot of ladder.
Formula for cosine trigonometric ratio:
[tex]cos\theta = \dfrac{Base}{Hypotenuse}[/tex]
In [tex]\triangle ABC[/tex]:
[tex]cosC=\dfrac{BC}{AC}[/tex]
Putting the values:
[tex]BC=\dfrac{AC}{4}[/tex]
[tex]cosC=\dfrac{\frac{AC}4}{AC}\\\Rightarrow cos C = \dfrac{1}{4}\\\Rightarrow \angle C = cos^{-1}(0.25)\\\Rightarrow \angle C =\bold{75.52^\circ}[/tex]
Nathaniel participated in an 18-mile race. He ran 1 2 mile in 1 6 hour. If he ran the entire race at the same pace, how long, in hours, will it take Nathaniel to finish the race?
Answer:
24 hours
Step-by-step explanation:
set up a ratio:
12 miles = 16 hours
------------- ------------
18 miles = x hours
cross multiply
12m * x = 16h * 18 m
solve for x
x=16h * 18m / 12m = 24 hours
