Answer:
- 5i and 5i
Step-by-step explanation:
The Fundamental theorem of Algebra states that a polynomial of degree 3 has 3 roots, real and/ or complex.
Complex roots occur in conjugate pairs.
Given 2 real roots x = 5, x = - 5
There cannot be complex roots as they occur in pairs which would result in the polynomial having 4 roots instead of 3.

What is the measure of ZJKL?
(Not drawn to scale)
1370
Marke this and return
Answer:
JKL = 117
Step-by-step explanation:
63 and JKL form a straight line and their sum is 180
63+ KJL = 180
Subtract 63 from each side
63+ KJL - 63 = 180-63
JKL = 117

Please help! Correct answer only, please! I need to finish this assignment this week. Determine the value of the following: A. B. C. D.
Answer:
B
Step-by-step explanation:
Given

solve each equation by graphing (work shown appreciated)
Answer:
Option A
Step-by-step explanation:
I used a graphing tool to graph the equations given. When graphed, the lines intercept at (-2,3). Therefore, it is the solution to the system of equations. See the picture attached for the graph.
Option A should be the correct answer.
Olivia is working two summer jobs, making $7 per hour walking dogs and making $15 per hour tutoring. In a given week, she can work a maximum of 18 total hours and must earn no less than $180. If x represents the number of hours walking dogs and y represents the number of hours tutoring, write and solve a system of inequalities graphically and determine one possible solution.
Answer:
x= 11.25 y=6.75
Step-by-step explanation:
we will present all of that to equations so we have
7x+15y=180
and x+y=18
by solving those 2 equations together we get the solution
The concession stand at the high school football stadium sells hot dogs and sodas. Jack bought 3 hotdogs and 2 sodas for a total of $12. Angie bought 1 hotdog and 4 sodas for $9. Solve a system of equations to determine the cost of 1 hotdog and 1 soda.
Answer: each soda costs $1.5 and each hotdog costs $3.
Step-by-step explanation:
If H is the price for one hotdog and S is the price for one soda, we have the equations:
for Jack.
3*H + 2*S = $12
For Angie.
1*H + 4*S = $9
Now we can isolate one of the variables in one of the equations and then replace it in the other equation, let's isolate H in the second equation:
H = $9 - 4*S
now we replace it in the first eq
3*H + 2*S = $12
3*($9 - 4*S) + 2*S = $12
$27 - 12*S + 2*S = $12
-10*S = $12 - $27 = -$15
S = $15/10 = $1.5
Now we can replace it in the equation for H and get:
H = $9 - 4*$1.5 = $3
So each soda costs $1.5 and each hotdog costs $3.
Answer: One hotdog cost $3 and One soda costs $1.5
Step-by-step explanation:
Let hotdogs be denoted by h
Let sodas be denoted as s
Jack bought 3 hotdogs and 2 sodas for a total of $12. This can be written as:
3h + 2s = 12
Angie bought 1 hotdog and 4 sodas for $9. This can be written as:
h + 4s = 9
3h + 2s = 12
h + 4s = 9
1 × (3h + 2s = 12)
3 × (h + 4s = 9)
3h + 2s = 12
3h + 12s = 27
Subtract the equation
-10s = -15
s = -15/-10
s = 1.5
One soda cost $1.5
Since h + 4s = 9
h + 4(1.5) = 9
h = 9 - 6
h = 3
One hotdog costs $3

Answer:
B. 45°
Step-by-step explanation:
The angles of a triangle have to add up to 180°.
In this triangle C is given as 90°. That leaves 90° for the sum of the two others. Since the triangle is symmetrical, you can divide 90° by 2 to get to equal angles of 45°.
Angle bisectors. I need help on how to solve.
Answer:
identify if the angle is a right angle, if it is bisected it means both sides are the same, set both equations equal to each other or add them up and set them equal to 90 or 180
Step-by-step explanation:
that is the explanation.

Please answer correctly !!!! Will mark brianliest !!!!!!!!!!!!!!
Answer:
x - 5
Step-by-step explanation:
Again, we can just write the width as (x² - 25) / (x + 5) which will be x - 5.
Answer:
area = length x width
x² - 25 = x + 5 · width
(x - 5)(x + 5) = (x + 5)w
(x - 5)(x + 5) / (x + 5) = (x + 5)w / (x + 5)
x - 5 = w
Step-by-step explanation:
1. write down the formula of area.
2. since the area is a difference of squares, factor them into two binomials, and replace the length by its measure. you can use w for width
3. to get width, divide the one of the binomials with the length that matches together to get w.

Which inequality has an open circle when it is graphed on a number line?
Answer:
See below
Step-by-step explanation:
If you consider an open circle, it would exclude the value with which we have circled when writing the inequality. Hence the only possible signs with in such an example can be a greater than sign ( > ) or less than sign ( < );
Let us take a look at an example to help. We are given a graph with an open circle on the number say 3. An arrow extends to the right of this number 3;
[tex]Inequality Sign - <,\\Inequality - x > 3,\\[/tex]

use long division to find the quotient below (5x^5+90x^2-135x)(x+3)
Answer:
quotient: 5x^4 -15x^3 +45x^2
Step-by-step explanation:
The division is performed in the attachment. At each stage, the quotient is the ratio of the highest-degree terms in dividend and divisor.
To find the dividend for the next step, subtract the product of quotient term and divisor from the current dividend. This is essentially the same way you do long division using integers.
