Answer:
-11 and -10
Step-by-step explanation:
-11² = -121
-(√119)² = -119
-10² = -100
_____
-√119 is between -11 and -10
You can substitute the value of y(5/6 x + 1) from the first equation for y in the second and get

which becomes

and you get
Answer:
The line is y = (1/2)x + 3
Step-by-step explanation:
We can calculate a slope. I'll use the two points (-4,1) and (-1,2.5).
Rise = (2.5-1) = 1.5
Run = (-1-(-4)) = 3
Rise/Run = Slope = (1.5/3.0) = 1/2
Find b, the y-intercept, by using point (-4,1) in the equation y = (1/2)x + b
y = (1/2)x + b
1 = (1/2)*(-4) + b
1 = -2 + b
b=3
The line is y = (1/2)x + 3
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!
