<span>r and s are parallel lines
so the angle 2 and 6 are called, corresponding angles
2 and 3 are opposite angle
but 3 and 7 are also interior corresponding angles so 7 and 3 are congruent, and so are 7 and 2 .
the </span><span> angles must be congruent to 2 are 3, 6 , 7</span>
Answer:
400 people english, 240 spanish, 120 vietnamese and 40 other
Step-by-step explanation:
50% is half of 800.
half of 800 is 400. 400 use english
to find 10 percent, you divide by 10. to find 30, you multiply that by 3.
80 times 3 is 240. 240 use spanish.
15 percent is 10 percent, which is 80, +40 because of the 5 percent
80+40 is 120. 120 use vietnamese.
5 percent is half of ten percent.
half of 80 is 40.
and it all adds up to 800
your welcome!:)
Answer:y² = 4 -
Explanation:The given expression is:
4x² + 25y² = 100
We need to isolate the y².
This can be done as follows:
4x² + 25y² - 4x² = 100 - 4x²
25y² = 100 - 4x²
![\frac{25y^2}{25} = \frac{100-4x^2}{25}](https://tex.z-dn.net/?f=%20%5Cfrac%7B25y%5E2%7D%7B25%7D%20%20%3D%20%20%5Cfrac%7B100-4x%5E2%7D%7B25%7D%20)
y² =
![\frac{x100-4x^2}{25}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx100-4x%5E2%7D%7B25%7D%20)
y² =
![\frac{100}{25} - \frac{4x^2}{25}](https://tex.z-dn.net/?f=%20%5Cfrac%7B100%7D%7B25%7D%20-%20%5Cfrac%7B4x%5E2%7D%7B25%7D%20)
y² = 4 -
![\frac{4x^2}{25}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4x%5E2%7D%7B25%7D%20)
Hope this helps :)
The product of 4 times 'm' . . . . . 4m
2 more than that . . . . . . . . . . . . 4m + 2
Your answer would be F(0)=f(-1)
