Step-by-step explanation:

7/10k=21

x7         x7 Multiply seven from each side of the equation.

10k=21

/10    /10 Divide ten from each side of the equation. 21/10=2.1

I need help this question?
Masja [62]

Answer:

Correct answer:  F. graph F or x ∈  |-5 ; 5| (including endpoints)

Step-by-step explanation:

Let us first define the absolute value:

| x |  = 1. { x with condition x ≥ 0 }

    or 2. { - x with condition x < 0 }

This is a linear inequality

1.  x ≤ 5  ∧  x ≥ 0   ⇒   0 ≤ x ≤ 5  or interval x ∈  |0 ; 5| (including endpoints)

2. - x ≤ 5  when we multiply both sides of the equation by -1 we get:

x ≥ -5 ∧ x < 0  ⇒  -5  ≤ x < 0 or interval x ∈  |-5 ; 0) (including -5)

The solution to this linear inequality is the union of these two intervals:

x ∈  |-5 ; 0) ∪ |0 ; 5|  ⇒ x ∈ |-5 ; 5| (including endpoints)

x ∈ |-5 ; 5| (including endpoints)

God is with you!!!

Write the equation of a line that passes through (-3/2, -5) and perpendicular to a line that contains (-1, -2) and (-2, -8).
liraira [26]

Answer:

find gradient/slope

-8-(-5) / -2-(-1) = -3/-1

= 3

y=3x+c

perpendicular line formula

m1(m2)= -1

(sub in the gradient before)

3(m2)= -1

m2= -1/3 ( perpendicular line gradient)

y=-1/3x+c

(sub in the coordinate)

-5=-1/3(-3/2)+c

-5=1/2+c

-11/2=c (y intercept)

answer: y= -1/3x - 11/2

2(5x-7)=2x+10 what Is the distributive property
jek_recluse [69]

Answer:x = 3

Step-by-step explanation:

2(5x-7)=2x+10

distribute 2(5x-7)

=2*5x - 2*7

  ∨       ∨

  10x - 14

10x - 14 = 2x + 10

add 14 to both sides

10x-14=2x+10

    +14      +14

simplify

10x=2x+24

subtract 2x to both sides

10x=2x+24

-2x -2x

simplify

8x=24

divide both sides by 8

 8x=24

÷8x ÷ 8x

x = 3
