Mathematics

garri49 [273]4 years ago

8 0

Step-by-step explanation:

When dividing by a negative number, you "flip" the inequalities sign so you would divide -20 by -2 which would leave you with 10. X is left where it is and you flip the inequalities sign to a ≥ sign.

final answer =

x ≥ 10

Write an equation and then solve for x

Nata [24]

Answer:

(5x-11)+(11x-63)+(2x+20)

Step-by-step explanation:

If you have to solve for it then just add all your like terms into a simplified equation. 18x-54 would be the simplified version

A line passes through (10,2) and (14,-22). Write the equation of the line in standard form.

jarptica [38.1K]

Answer:

The equation of the line in standard form is:

$6x + y = 62$

Step-by-step explanation:

Given the points

(10,2)

(14,-22)

Determining the slope between (10, 2) and (14, -22)

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(10,\:2\right),\:\left(x_2,\:y_2\right)=\left(14,\:-22\right)$

$m=\frac{-22-2}{14-10}$

$m=-6$

The point-slope form of the line equation is

$y-y_1=m\left(x-x_1\right)$

where

m is the slope of the line

(x₁, y₁) is the point

substituting the values m = -6 and the point (10, 2) in the point-slope form of the line equation

$y-y_1=m\left(x-x_1\right)$

$y - 2 = -6(x - 10)$

$y - 2 = -6x +60$

adding 2 to both sides

$y-2+2 = -6x + 60 + 2$

$y = -6x + 62$

We can write the equation in the standard form such as

Ax + By = C

Thus,

$y = -6x + 62$

adding -6x to both sides

$6x + y = -6x + 62 + -6x$

$6x + y = 62$

Therefore, the equation of the line in standard form is:

$6x + y = 62$

1. We can use division to solve real life problems, such as:

iren2701 [21]

Well, let's look at the answer choices.
A) If you want to fond the total cost of two sweaters you would add, not divide. So this isn't it.
B) To find out how much older someone is you would subtract. So this isn't it either.
C) To find out how many desks are needed you would multiply, since you know you need 3 rows of desks with 7 students each (3 x 7). Again, not it.
D) To find out how many pencils each student would get, you'd divide. You would divide 56 by 9. So your answer is D.
