Multiply all terms by the same value to eliminate fraction denominators
Answer:
x= -88
Step-by-step explanation:
We move all terms to the left:
x/4+9- (-13)=0
Then we add all the numbers together, and all the variables:
x/4+22=0
We multiply all the terms by the denominator:
x+22*4=0
We all all the numbers together, and all the variables:
x+88=0
We move all the terms containing x to the left, all other terms to the right:
x= -88

If
f (x) = x^2 - 4
what is the average rate of change from x = 3 to x = 5?
Answers
Answer:
The average rate of change is 8
Step-by-step explanation:
Mathematically, we have the average rate of change over a given interval as;
f(b) - f(a)/b-a
Where the interval is [a,b]
With respect to this question, a = 3 and b = 5
f(a) = f(3) = 3^2 - 4 = 9-4 = 5
f(b) = f(5) = 5^2 - 4 = 25-4 = 21
Thus, the average rate of change over the intervals will be;
(21-5)/(5-3) = 16/2 = 8

Using the Pythagorean theorem:
14^2 = 8^2 + x^2
196 = 64 + x^2
Subtract 64 from both sides:
132 = x^2
Take the square root of both sides:
X = 11.49
Rounded to nearest tenth = 11.5
Answer:
missing side = 11.5
Step-by-step explanation:
[tex]a^{2} = c^{2} - b^{2}[/tex]
[tex]a^{2} = 14^{2} - 8^{2}[/tex]
[tex]a^{2} = 196 - 64[/tex]
[tex]a^{2} = 132[/tex]
[tex]\sqrt{a^{2} } - \sqrt{132}[/tex]
a = 11.489
round to the nearest tenth:
11.489 = 11.5

If m\angle VXW=28\degreem∠VXW=28°, what is the measure of arc VW?
Answers
Answer:
m(arc VW) = 56°
Step-by-step explanation:
m∠VXW = 28°
By inscribed angle theorem,
"Length of intercepted arc measures the double of the inscribed angle"
m(arc VW) = 2m(∠VXW)
m(arc VW) = 2(28°)
m(arc VW) = 56°
Therefore, measure of arc VW is 56°.
