Answer:
y = 12x + 8
Step-by-step explanation:
1. 3x - 1/4y = -2
Subtract 3x from both sides
2. -1/4y = -2 - 3x
The equation is in standard form.
3. -1/4y = -3x - 3
Multiply both sides by -4
4. Check photo for step 4
Divide by -1/4 = -0.25 undoes the multiplication -1/4 = -0.25
5. y = (-3x-2) / (-1/4)
Divide -2 - 3x by -1/4 = -0.25 by multiplying -2 - 3x by the reciprocal of -1/4 = -0.25
y = 12x + 8
Divide 60 and 40 by muliples to get a perfect anwser
Answer:
x = 3
TU = 35
UV = 35
TV = 70
Step-by-step explanation:
As U is the midpoint of TV:
⇒ TU = UV
⇒ 8x + 11 = 12x - 1
⇒ 8x + 11 - 11 = 12x - 1 - 11
⇒ 8x = 12x - 12
⇒ 8x - 12x = 12x - 12 - 12x
⇒ -4x = -12
⇒ -4x ÷ -4 = -12 ÷ -4
⇒ x = 3
Substitute the found value of x into the expression for TU:
⇒ TU = 8x + 11
⇒ TU = 8(3) + 11
⇒ TU = 24 + 11
⇒ TU = 35
Using the <u>transitive property of equality</u>:
As UV = TU and TU = 15 then UV = 35
Using the <u>segment addition postulate</u>:
⇒ TV = TU + UV
⇒ TV = 35 + 35
⇒ TV = 70
