Answer:
x = ![-\frac{41}{19}](https://tex.z-dn.net/?f=-%5Cfrac%7B41%7D%7B19%7D)
y = ![\frac{7}{19}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B19%7D)
Step-by-step explanation:
2x = 10y - 8
3x + 4y + 5 = 0
2x = 10y - 8
x = 5y - 4
3x + 4y + 5 = 0
3 ( 5y - 4 ) + 4y + 5 = 0
19y - 7 = 0
19y = 7
y = ![\frac{7}{19}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B19%7D)
x = 5y - 4
x = 5 (
) - 4
x = ![-\frac{41}{19}](https://tex.z-dn.net/?f=-%5Cfrac%7B41%7D%7B19%7D)
(4xy - 3z)²
(4xy - 3z)(4xy - 3z)
4xy(4xy - 3z) - 3z(4xy - 3z)
16x²y² - 12xyz -12xyz + 9z²
16x²y² - 24xyz + 9z², a perfect square trinomial.
1/4 because it's only one four and u have 25% of chosen a four
Answer:
The answer is 2.
Step-by-step explanation:
Given: - 6 - (-6) + 7 + ( - 4) + ( - 1)
= - 6 + 6 + 7 - 4 - 1
= 6 + 7 - 6 - 4 - 1
= (6 + 7) - (6 + 4 + 1)
= 13 - 11
= 2
Hence, the answer.
Answer:
angle one is 62 degrees
Step-by-step explanation:
3x+2+5x+18=180
x=20
5*20+18=118
180-118=62
