Answer:
Step-by-step explanation:
y = 4x+2
slope of the line is 4
slope of any parallel to the line is also 4
point-slope equation for line of slope 4 that passes through (8,4):
y-4 = 4(x-8)
rearrange to slope-intercept form:
y = 4x - 28
Answer:
8r^4
Step-by-step explanation:
√(64r^8) = √((8r^4)^2) = 8r^4

You can make use of either or both of these rules of exponents:
(a^b)^c = a^(b·c) . . . . . used above
![\sqrt[n]{a}=a^{\frac{1}{n}}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%7D%3Da%5E%7B%5Cfrac%7B1%7D%7Bn%7D%7D)
Using the second rule, you can write the expression as ...
Answer:
3
Step-by-step explanation:
let n be the number, then
= 1 ← multiply both sides by 7 + n
10 = 7 + n ( subtract 7 from both sides )
3 = n
Step-by-step explanation:
4x2+8x−3=0
For this equation: a=4, b=8, c=-3
4x2+8x+−3=0
Step 1: Use quadratic formula with a=4, b=8, c=-3.
x=
−b±√b2−4ac
2a
x= −(8)±√(8)2−4(4)(−3)
2(4)
x= −8±√112
8 x=−1+
1 2 √7 or x=−1+
−1 2 √7
Answer: x=−1+
1 2√7 or x=−1+
−1 2 √7
A percent mean per 100 so 500% is 500/100
which is 5, and I guess you could use 500/100 and then just divide each by 100 to get the fraction 5/1.
so 5.0 as a decimal
5/1 as a fraction
