Step-by-step explanation:

Solve the inequality.

−13x+10>17
Which inequality represents the solutions to this inequality?
a) x<7x<7

b) x>−21x>−21

c) x<−21x<−21

d) x>7x>7

Answers

The solution to inequality is less than the negative of 21. Then the correct option is C.

What is inequality?

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

The inequality is given below.

−(1/3)x + 10 > 17

Then the solution to the inequality will be

−(1/3)x + 10 > 17

−(1/3)x > 17− 10

−(1/3)x > 7

When the sign is changed then the equality sign also changed.

(1/3)x < −7

x < − 21

The value of x is less than the negative of 21.

Thus, the correct option is C.

n = 66

Step-by-step explanation:

you can make a proportion 3/99 = 2/x

[tex] \frac{3}{99} = \frac{2}{x} [/tex]

99 * 2= 198

3 * x = 3x

so the equation would be 198 = 3x

than do 198 ÷ 3 on ur calculator

so x (or n in this context) would equal 66

You move left 5 units. You end at (-1, 5). Where did you start?

Answers

Answer:

(4,5)

Step-by-step explanation:

Hello!

If you move 5 units to the left, you change the x-value in (x, y) by -5.

Let the original x-value be x:

x - 5 = -1x = 4

The original x-value is 4. Since you didn't change the y-value (up/down), you can keep the same y-value for the coordinate.

The original point was at (4,5)

Answer:

You started at (4, 5)

Step-by-step explanation:

The first number of coordinate pair is x. you started at the right and THEN moved the the left, as stated in the question. So -1 + 5 is 4.
So you started at (4, 5)

d 0 2 4 6 8 10 12

What is the rate of change of the function?
O 1.7 cm per day
O 8.4 cm per day
O 1.4 cm per day
O 0.7 cm per day

Answers

The rate of change of the function the height of a plant is gotten as; D: 0.7

How to find the rate of change?

To find the rate of change, we will use the formula;

Rate of change = (y2 - y1)/(x2 - x1)

From the given table, we can solve for the rate of change by picking two consecutive points to get;

Rate of change = (9.6 - 8.2)/(2 - 0)

Rate of change = 1.4/2

Rate of change = 0.7

What was his mistake?

Answers

Circle the first line.

His mistake was: He substituted y from 2nd equation in 1st equation incorrectly. There is a minus sign before y and it wasn't taken into the account.

The correct steps are:

2x - y = 18

2x - (4x + 2) = 18

2x - 4x - 2 = 18

-2x - 2 = 18

-2x = 20

x = -10

y = 4x + 2

y = 4(-10) + 2

y = -40 + 2

y = -38

The measure of the angle m1 is 110 degrees

How to determine the measure of angle m1?

The measures of the arcs are given as:

Arc 1 = 130

Arc 2 = 90

The measure of the angle is calculated using:

Angle = 0.5 * (Arc 1 + Arc 2)

So, we have:

Angle = 0.5 * (130 + 90)

Evaluate

Angle = 110

Hence, the measure of angle m1 is 110 degrees

What is a Coordinate Plane?

This refers to the tool that is used to graph points on a two-dimensional plane that intersects two number lines.

Hence, given the information in the given diagram, there is a coordinate plane that shows a circle at the center that has certain values on the y and x-axis.

We can state that the point (1, StartRoot 7 EndRoot) lies on the circle shown because the distance from (–2, 0) to (1, StartRoot 7 EndRoot) is 4 units.
