One winter day, the outside temperature, y, never dropped below −1°. The inside of a car was always warmer than the temperature outside by at least 4°. Which graph of a system of inequalities represents this scenario?

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.

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.

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).

Step-by-step explanation:

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 .

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.

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.

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

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

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)

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.
