how do i solve -3x + 2y = -4

Answers

Answer 1

Answer:

y= 3/2 x -2

Step-by-step explanation:

I guess you want to find the y=mx+b form

So you do +3x on both sides which will gave you: 2y= 3x-4

Then, you will divide by two on both sides to find the y value: 2y/2 = (3x-4)/ 2

So 3/2 is the fraction like the answer above and -4/2 = -2

Hope that helps :)

Answer:

3[tex]\sqrt{3}[/tex] and [tex]\sqrt{7}[/tex]

Step-by-step explanation:

Simplifying surds is similar to collecting like terms in algebra.

If the surds have the same value then collect them by adding/ subtracting their coefficients.

(a)

[tex]\sqrt{3}[/tex] (7 - 2 + 1 - 3)

= [tex]\sqrt{3}[/tex] (3)

= 3[tex]\sqrt{3}[/tex]

(b)

[tex]\sqrt{7}[/tex] (5 + 4 - 8)

= [tex]\sqrt{7}[/tex] (1)

= [tex]\sqrt{7}[/tex]

The scale factor from a small triangle ABC to a large
triangle XYZ is 4. How many times larger will the
perimeter of triangle XYZ be than the perimeter of
triangle ABC?

Answers

9514 1404 393

Answer:

  c  4 times

Step-by-step explanation:

If the side lengths of the original triangle are AB, BC, and CA, then those of the dilated triangle are 4AB, 4BC, 4CA.

The sums of these are the perimeters.

  P = AB +BC +CA

  perimeter of XYZ = 4AB +4BC +4CA = 4(AB +BC +CA) = 4P

The perimeter of XYZ is 4 times the perimeter of ABC.

152=8(3a-2) justify each step

Answers

Step-by-step explanation:

152 = 8(3a - 2)

152 = 8 × 3a - 8 × 2

152 = 24a - 16

152 + 16 = 24a

168 = 24a

a = 168/24

a = 7

Answer:

-7

Step-by-step explanation:

152=8(3a-2)

8(3a-2)=152

8(3a-2)/8=(152){8)

3a-2=19

3a-2+2=19+2

3a=21

3a/3=21/3

a=-7

Convert:4 gal= qt what is it

Answers

Answer:

XY zand ABC are similar. If angle X is 32 degrees and angle Y is 84

Answers

Answer:

B

Step-by-step explanation:

A triangle always has a degree total of 180. x+y=116 180-116=64 therefore the last angle, angle c, must be 64 degrees.

Answer: B. 64 degrees

Step-by-step explanation:

∠C = 180° - (∠X + ∠Y)

∠C = 180° - (32° + 84°) = 180° - 116° = 64°

The Nguyen family is traveling cross-country, driving 300 miles each day. Let 2 represent the number of days in the trip and let y represent the total number
of miles driven.
Write an equation to model their trip.
Enter the correct equation in the box.

Answers

Step-by-step explanation:

y = Total number of miles driven

= Number of days * Number of miles per day

= (x) * (300).

Therefore the equation is y = 300x.

When x = 2, y = 300(2) = 600.

The Nguyen family drove 600 miles during the 2 days.
