what is 2+2? plz help meh

Answer:

add 2x to both sides

Step-by-step explanation:

-x+2y=-10

2y=x-10

y=1/2x-5

Answer:

No because whenever you plug in 2 into the x spots your answer is going to come out as positive one not -8.

Answer:

there is a solution but x will equal 0

Step-by-step explanation:

-6x-30=6x-30

combine -6x and 6x

-12x -30=-30

add 30 and -30

-12x=0

since -12 don't equal 0 then x will equal 0

so the final answer is x=0

Answer: 11

Step-by-step explanation:

i got 100 on the quiz

Xavier's organizer is 11 inches wide.

In addition, items are combined and counted as a single large group. The process of adding two or more numbers together is known as addition in mathematics. The terms "addends" and "sum" refer to the numbers that are added and the result of the operation, respectively.

Given, he wants 4 compartments which are each 2 inches wide and 1 compartment which is 3 inches wide.

4 compartments have 2 inches wide,

that means,

2 x 4= 8 inches wide.

And one compartment has 3 inches wide.

That means, the total width is

= adding all the widths

= 8+ 3

= 11 inches.

Therefore, the organizer's width is 11 inches.

The Dx for this system of equation can be found by the determinant of option (C) matrix  [tex]\left[\begin{array}{ccc}17&-3\\8&4\end{array}\right][/tex] is the correct answer.

A matrix is an arrangement of numbers, expressions or symbols arranged in rows and columns as a rectangular array. These rows and columns define the size or dimension of a matrix.

For the given situation,

The system of equations are

2x − 3y = 17

5x + 4y = 8

This system of equations can be write in matrix form as

[tex]\left[\begin{array}{ccc}2&-3\\5&4\end{array}\right] =\left[\begin{array}{c}17&8\end{array}\right][/tex]

The Dx for this system of equation can be found by augmenting these matrices.

The augmentation is of the form,

[tex]\left[\begin{array}{ccc}17&-3\\8&4\end{array}\right][/tex]

We need to substitute the output value in place of x value in the matrix. The determination of this matrix gives the value of Dx.

Hence we can conclude that the Dx for this system of equation can be found by the determinant of option (C) matrix  [tex]\left[\begin{array}{ccc}17&-3\\8&4\end{array}\right][/tex] is the correct answer.

Step-by-step explanation:

Set the x value to be -2, -1, 0, 1, and 2.

If x is -2, y is -5.

2 (-2) - 1 = -5

The coordinate pair would be (-2, -5).

If x is -1, y is -3.

2 (-1) - 1 = -3

The coordinate pair would be (-1, -3).

If x is 0, y is -1.

2 (0) - 1 = -1

The coordinate pair would be (0, -1).

If x is 1, y is 1.

2 (1) - 1 = -1

The coordinate pair would be (1, 1).

If x is 2, y is 3.

2 (2) - 1 = 3

The coordinate pair would be (2, 3).

Five ordered pairs could be (-2,-5), (-1,-3), (0,-1), (1,1), and (2,3).

Put any value of x to the equation of the function and calculate y.

y = 2x - 1

for x = -2 → y = 2(-2) - 1 = -4 - 1 = -5 → (-2, -5)

for x = -1 → y = 2(-1) - 1 = -2 - 1 = -3 → (-1, -3)

for x = 0 → y = 2(0) - 1 = 0 - 1 = -1 → (0, -1)

for x = 1 → y = 2(1) - 1 = 2 - 1 = 1 → (1, 1)

for x = 2 → y = 2(2) - 1 = 4 - 1 = 3 → (2, 3)

Answer: (-2,-5); (-1,-3); (0,-1); (1, 1); (2; 3)

Research by The national sleep foundation requires Americans to sleep at least 7.1 hours per day.

There two types of sleep deprivation or sleep deficit: partial sleep deprivation and total sleep deprivation. In Partial sleep deprivation, the person may not get enough sleep per day example not up to 7.1 hours per day. Total sleep deprivation means that the affected person does not sleep for up 24 hours ie a full day.

Answer:

John will get 16 3/4 pounds-units of dog food.

Step-by-step explanation:

The total amount of portions of dog food is obtained by dividing the total amount of dog food, measured in pounds, by the amount of dog food per portion, measured in pounds per unit:

[tex]n = \frac{12\,pd}{0.75\,\frac{pd}{unit} }[/tex]

[tex]n = 16\,units[/tex]

John will get 16 3/4 pounds-units of dog food.

The term U describes the incenter of the given triangle.

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

STR is a given triangle.

Let us understand the differences between Orthocenter, Incenter, Centroid and Circumcenter.

Circumcenter is the point of which is equidistant from all the vertices of the triangle.

Incenter is the point of which is equidistant from the sides of the triangle.

Orthocenter is the point at which all the altitudes of the triangle intersect.

centroid is the point of intersection of the medians of the triangle.

By observing this we can tell that U is the incenter of the triangle RST.

Hence, the term U describes the incenter of the given triangle.

Step-by-step explanation:

For the first step, we need to divide 128 by 4 to get the amount of pennies she gave to each friend: 128/4 = 32

For the second step, we need to subtract 128 from 442 to find out how many pennies she has left: 442-128 = 314

Step-by-step explanation:

The sum of angles of a triangle equals the straight angle (180°), therefore:

3x + 12x + 1 + 16x - 7 = 180

31x-6=180

31x = 180 + 6

31x = 186

x = 186/31

x = 6

Then, the angles are:

3(6) = 18°

16*6 - 7 = 89°

12(6) +1 = 73°
