The graph of a system of inequalities that represents this scenario will be A. On a coordinate plane, 2 straight lines are shown. The first solid line is horizontal to the y-axis at y = negative 1. Everything above the line is shaded. The second dashed line has a positive slope and goes through (0, negative 4) and (2, negative 2). Everything below and to the right of the line is shaded.
What is a inequality?In Algebra, an inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions.
On one day, x, the outside temperature never fell below 1°. A automobile was always at least 4 degrees warmer inside than it was outdoors.
y -1 is the inequality for the first line.
Y > x + 4 is the inequality that represents the second line.
The darkened area is therefore above the first line, which is a solid horizontal line.
The shaded area lies above and to the left of the second line, which has a broken line and a positive slope.
Therefore, the correct option is A.

Find all real and imaginary solutions to the equation.
x^3-2x^2+16x-32=0
Answer:
The solution of [tex]x^3-2x^2+16x-32=0[/tex] is [tex]\mathbf{x=2,x=4i,x=-4i}[/tex]
So, the real solutions is: x = 2
Imaginary solutions are : x = 4i, x = -4i
Step-by-step explanation:
We need to find real and imaginary solutions to the equations [tex]x^3-2x^2+16x-32=0[/tex]
First of all we will make groups
[tex](x^3-2x^2)(+16x-32)=0[/tex]
Finding common terms from the groups
[tex]x^2(x-2)+16(x-2)=0\\(x-2)(x^2+16)=0[/tex]
Now we know that if ab=0 then a=0 , b=0
[tex]x-2=0, x^2+16=0\\Simplifying:\\x=2, x^2=-16\\Taking\: square\: root\\x=2,\sqrt{x^2}=\sqrt{-16}\\x=2, x=\pm\sqrt{-16}\\x=2,x=\m\sqrt{-1}\sqrt{16} \\We\:know\:\sqrt{-1}=i \:and \sqrt{x} \:\sqrt{16}=4 \\x=2,x=\pm4i\\x=2,x=4i,x=-4i[/tex]
The solution of [tex]x^3-2x^2+16x-32=0[/tex] is [tex]\mathbf{x=2,x=4i,x=-4i}[/tex]
So, the real solutions is: x = 2
Imaginary solutions are : x = 4i, x = -4i

Solve the equation 2 (x - 1/2)=3(5 - 2x) Show the steps in your solution.
Answer:
x = 2
Step-by-step explanation:
2(x - 1/2) = 3(5 - 2x) (distribute 2 and 3)
2x - 1 = 15 - 6x (add 6x on both sides)
8x - 1 = 15 (add 1 on both sides)
8x = 16 (divide both sides by 8)
x = 2
CHECK
2(2 - 1/2) = 3(5 - 2(2)) (solve what's in parenthesis)
2(1.5) = 3(1) (distribute)
3 = 3

What is the value of x?
Answer:
x=32
Step-by-step explanation:
1. Find the angle next to the 122
Since it is a 180 degree total angle, you subtract 180-122 to get 58 degrees
2. You know two out of the 3 angles now because the square indicates a 90 degree angle. So you add 90 + 58 = 148
3. Since the total amount of degrees in a triangle is 180, you subtract 180-148 to get 32 degrees
Hope this helps! Please give me brainliest!

D. 7 cm, 25 cm, 26 cm
Please Help me !!!!!!!
Answer:
b and d I think are both right but if you can only pick one go with B
The measure that could be the side lengths of a right triangle is 30 cm, 72 cm, 78 cm, the correct option is B.
What is the right triangle?A right-angle triangle is a triangle that has a side opposite to the right angle the largest side and is referred to as the hypotenuse. The angle of a right angle is always 90 degrees.
We are given that;
The right triangle
Now,
We can use this equation to test each option by plugging in the values and checking if they satisfy the equation.
A. 7 cm, 21 cm, 25 cm
7^2 + 21^2 = 25^2
49 + 441 = 625
490 = 625
False
This option does not satisfy the Pythagorean theorem, so it cannot be the side lengths of a right triangle.
B. 30 cm, 72 cm, 78 cm
30^2 + 72^2 = 78^2
900 + 5184 = 6084
6084 = 6084
True
Therefore, by right angle triangle the answer will be 30 cm, 72 cm, 78 cm.

The value of x as evident in the task content is; 14 and hence, the measure of angles m<DEC and m< CEF are; 142° and 38° respectively.
What are the justification s for the statements as indicated in the task content?It follows from the task content that the justifications of the statements are to be indicated.
On this note, the justifications are as follows;
m<DEF = 180°; The measure of angle on a line is 180°.m<DEC + m<CEF = 180; The algebraic sum of angles on a straight line is; 180°.(11x -12) + (2x +10) = 180; Substitute the given expressions for the angles DEC and CEF respectively.13x - 2 = 180; Collect like terms.13x = 182; Add 2 to both sides of the equation.x = 14; Divide both sides of the equation by 13.Hence, the measure of angle; m<DEC = 11x -12.
= 11(14) - 12
= 142°.
Ultimately, the measure of angle m<CEF is;
m<CEF = 180 -142
m<CEF = 38°.

Lorena's bank will loan money to customers if they overdraw their accounts by less than 100$. (To overdraw an account means to have the account balance fall below zero.) Lorena started out with a balance of $13.00 and made a withdrawal from her account of $81.50.
Answer:
a. POSITIVE NUMBER mean availability of money
NEGATIVE NUMBER mean Overdrawn
ZERO mean unavailability of money
b. YES
Step-by-step explanation:
a. Based on the information given the POSITIVE NUMBER mean the AVAILABILITY of some amount of money
A NEGATIVE NUMBER on the other hand mean OVERDRAWN which means that the customer account balance fall below Zero amount
ZERO mean UNAVAILABILITY OF MONEY
b. YES. Based on the information given if Lorena's final account balance has the amount of -$68.50 the bank will loan her reason been that we were told that the bank will give loan to their customers if they overdraw their accounts by less than the amount of $100 in which case Lorena's final account balance has the amount of -$68.50 which is less than $100. Hence the bank will loan her .

1. (2, -22)
2. (2, 48)
3. (-2, 2)
4. (-2, -20)
Answer:
1
Step-by-step explanation:
A system of equation is a set of a number of equation used for finding their solution. The solution of the given system of equations is (2,-22). The correct answer is option 1.
What is a system of equations?A system of linear equation can be defined as a number of equations needed to find the solution. On the basis of the number of solutions a set of equations can be called either consistent or inconsistent.
The given equations are
y = -6x -10 and y = -1/2x -21
They can be rewritten as,
y + 6x = -10 ------------------- (1)
2y + x = -42 ------------------- (2)
To get the value of x ,
(2y + x) - 2(y + 6x) = -42 - 2×(-10)
=> -11x = -22
=> x = 2
Substitute x = 8 in equation (1) to get y,
y = -10 - 12
y = -22
Hence, the solution for the given system of equation is (2,-22).

Fill in the table using this function rule y = 4 + 5x
Step-by-step explanation:
bruh ,come on this was so easy
The value of y using this function rule y = 4 + 5x is 19,29,34 and 49.
We are given that;
The function y=4+5x
Now,
To fill in the table using the function rule y = 4 + 5x,
we need to substitute each value of x into the rule and calculate, the corresponding value of y. For example, when x = 3, we get:
y = 4 + 5x
y = 4 + 5(3)
y = 4 + 15
y = 19
We can repeat this process for the other values of x and fill in the table as follows:
| x | y |
| 3 | 19|
| 5 | 29|
| 6 | 34|
| 9 | 49|
Therefore, by the function answer will be 19,29,34 and 49.
