Answer:8
Step-by-step explanation:
X+56=x^2
X^2-x-56=0
X^2-8x+7x-56=0
X(x-8)+7(x-8)=0
(X+7)(x-8)=0
X+7=0 or x-8=0
X=-7 or x=8
The value of m must be 4 and the value of b must NOT be -3.
No matter what numbers they involve, two equations with the SAME slope (m) and a DIFFERENT y-intercept (b) have no solution. This is because they form parallel lines, never crossing and therefore never giving a solution.
The correct answer for the question that is being presented above is this one: "b. $2.78." Andrew owns stock in Hyren Airlines and as a result gets paid dividends worth $539.70 every year. If Andrew owns 105 shares of Hyren Airlines, the dividend of each share yields <span>b. $2.78</span>
Answer:
8%
Step-by-step explanation:
Let's say the tax percent was x%. Then, we can write the equation:
4.75 + x% * 4.75 = 5.13
Notice that both terms on the left have 4.75 so factor that out:
4.75 * (1 + x%) = 5.13
Divide both sides by 4.75:
1 + x% = 5.13/4.75 = 1.08
Subtract 1 from both sides:
x% = 0.08
Remember that % simply means "out of 100", so x% = x/100:
x/100 = 0.08
Multiply both sides by 100:
x = 8
Thus, the tax rate is 8%.
Hope this helps!
