Answer:
1/2
Step-by-step explanation:
3/8 + 2/8 is 5/8, 1/2 is equal to 4/8, so 5/8 is only 1/8 away from 1/2 while 5/8 is also 3/8 away from 1 or 8/8 therefore, it is closer to 1/2
Answer:
2) x times the seventh root of x cubed
Step-by-step explanation:
![\displaystyle\sqrt[7]{x^5}\cdot\sqrt[7]{x^5}=\sqrt[7]{x^{5+5}}\\\\=\sqrt[7]{x^{7+3}}=\sqrt[7]{x^7}\cdot\sqrt[7]{x^3}\\\\=x\sqrt[7]{x^3}](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Csqrt%5B7%5D%7Bx%5E5%7D%5Ccdot%5Csqrt%5B7%5D%7Bx%5E5%7D%3D%5Csqrt%5B7%5D%7Bx%5E%7B5%2B5%7D%7D%5C%5C%5C%5C%3D%5Csqrt%5B7%5D%7Bx%5E%7B7%2B3%7D%7D%3D%5Csqrt%5B7%5D%7Bx%5E7%7D%5Ccdot%5Csqrt%5B7%5D%7Bx%5E3%7D%5C%5C%5C%5C%3Dx%5Csqrt%5B7%5D%7Bx%5E3%7D)
To factor quadratic equations of the form ax^2+bx+c=y, you must find two values, j and k, which satisfy two conditions.
jk=ac and j+k=b
The you replace the single linear term bx with jx and kx. Finally then you factor the first pair of terms and the second pair of terms. In this problem...
2k^2-5k-18=0
2k^2+4k-9k-18=0
2k(k+2)-9(k+2)=0
(2k-9)(k+2)=0
so k=-2 and 9/2
k=(-2, 4.5)
Answer:
option A
Step-by-step explanation:
We can find the standard form by expanding the equation:
y = 3(x-4)^2 - 22
y = 3(x^2 - 8x + 16) - 22
y = 3x^2 - 24x + 48 - 22
y= 3x^2 - 24x + 26
So the correct option is option A
Answer:
x(1.25)
Step-by-step explanation:
x is the yards.
so for example if you need 2 yards of fabric replace x with 2.
