Answer:

Step-by-step explanation:

x= -10

(if you are solving for the x value):

-4x+2=42

subtract two to both sides to cancel the two from the side with -4x

-4x+2-2=42-2

-4x=40

then divide both sides by -4 to get the x by its self

-4x/-4=40/-4

so..

x= -10

Answer:

x = -10

Step-by-step explanation:

move all the constants (numbers without variables) to one side to get

-4x = 42 - 2

-4x = 40

multiply by -1

4x = -40

divide by 4

x = -10

What are the coordinates of the vertices of the rose garden after a translation two yards east and four yards south? Use the ter
melisa1 [442]

Answer:

The coordinates of the vertices of the original rose garden are A(3, 6), B(3, 3), C(4, 3), and D(4, 6).

Because the rose garden is translated 2 yards east (2 units in the positive x-direction) and 4 yards south (4 yards in the negative y-direction), add 2 units to the x-coordinates and -4 units to the y-coordinates of all the original vertices.

A(3, 6) will become A'[(3 + 2), (6 + (-4))], or A′(5, 2).

B(3, 3) will become B'[(3 + 2), (3 + (-4))], or B′(5, -1).

C(4, 3) will become C'[(4 + 2), (3 + (-4))], or C′(6, -1).

D(4, 6) will become D'[(4 + 2), (6 + (-4))], or D′(6, 2).

Rob notices that 55 percent of the people leaving the supermarket chhose plastic bags instead of paper bags. out of 600 people,
Temka [501]
To solve this answer, you are trying to find 55% of 600, because that is the number of people who chose plastic bag.

55% can be re-written as 55/100 OR 0.55 since percentages are always out of 100.

So, we do 0.55*600, which gives us 330. 330 people carry plastic bags.
