How are zeros identified in a rational expression? Please explain thoroughly.
Answer:
To find the zeroes of a rational function, set the numerator equal to zero and solve for the \begin{align*}x\end{align*} values. When a hole and a zero occur at the same point, the hole wins and there is no zero at that point.

How many solutions does the equation −3x−17=−17−3x have?
Answer:
an infinite number of solutions
Step-by-step explanation:
−3x −17 = −17 −3x
left side = right side TRUE because -3x-17 is the same as -17-3x
we can rearrange the the equation
−3x −17 +17 = −17 +17−3x, add 17 on both sides of the equations
-3x = -3x, divide both sides by (-3)
x = x
Since this equation is always true ( for any number ) we have an infinite number of solutions (since there are is an infinity of numbers.)

Jim provides photos for two online sites: site A and site B.
Site A pays $0.85 for every photo Jim provides.
The amount in dollars (y) site B pays as a function of the number of photos provided (x) is represented by the equation y = 0.40x.
How much more was Jim paid at site A than at site B, if he provided five photos for each site? (1 point)
A. $1.15
B. $1.35
C. $2.15
D. $2.25
Answer:
Step-by-step explanation:
We can use the same equation to figure out with only substituting the amount he was paid per photo.
Site A y = $0.85x = $0.85(5) = $4.25
Site B y = $0.40x = $0.40(5) = $2.00
We can see that Jim was paid $2.25 more at site A than Site B.
Answer:
D. 2.25
Step-by-step explanation:
y=0.85x, y=0.4x
0.85-0.4=0.45
0.45*5=2.25

Answer:
X and y answer is 45 degrees
Answer:
x = 20, y = 70 degrees.
Step-by-step explanation:
x + y = 90 degrees ( As the large triangle is right-angled).
Now x is the base angle of an isosceles triangle so the small angle that is part of the right angle = x. Call this angle z.
Consider the small triangle which includes 40 degrees:
y + 40 + 90 - z = 180 But as z = x:
y + 130 - x = 180
y - x = 50
Adding the equation to the highlighted equation above we have:
2y = 90 + 50
2y = 140
y = 70 degrees.
So x + 70 = 90
giving x = 20 degrees.
Rida and Elisa are each paid by the hour. Rida worked 5 1/2 hours and earned 77. Elisa worked 3 3/4 hours and earned 60. Whose hourly rate is greater?
Answer:
The answer is Elisa's Hourly rate
Step-by-step explanation:
Rida and Elisa are each paid by the hour.
Rida worked 5 1/2 hours and earned 77.
5 1/2 = 11/2 = 5.5 Hours
Rida earned 77 in 5.5 hours
Elisa worked 3 3/4 hours and earned 60.
3 3/4 = 15/4 = 3.75 Hours
Elisa earned 60 in 3.75 hours
Elisa earns more than in less time as compared to Rida
so Elisa's hourly rate is greater than Rida
Thus, The answer is Elisa's Hourly rate
-TheUnknownScientist 72
Step-by-step explanation:
we find out by checking how much they got for 1 hour.
so, 77 earned in 5 1/2 hours. how much in only 1 hour ?
77 / (5 1/2) = 77 / 11/2 = 77 × 2/11 = 7×2 = 14
and 60 earned in 3 3/4 hours. how much in 1 hour ?
60 / (3 3/4) = 60 / 15/4 = 60 × 4/15 = 4×4 = 16
so Elisa's hourly rate is greater.
