Answer:
x^2+17x+91=0
a = 1; b = 17; c = +91;
Δ = b2-4ac
Δ = 172-4·1·91
Δ = -75
Delta is less than zero, so there is no solution for the equation

An electrician charges an hourly rate of $50, but also charges a fixed fee for making house calls regardless of time spend on the job. One day, the electrician earned a total of $250 for a 2 hour job. Write an equation for C,C, in terms of t,t, representing the total cost of the electrician's services if the electrician spends tt hours at the house working.
Answers
Answer:
C=50t+150
Step-by-step explanation:
From the information given, the equation will need to show that the total cost of the electrician services would be equal to 50 that is the hourly rate for the number of hours spent working plus the fixed fee:
Fixed fee=250-(50*2)=250-100=150
According to this, the equation would be:
C=50t+150, where C is the total cost of the electrician's services and t is the number of hours spent working.

math(60)
science (70)
total (200)
History total (150)
Math total (110)
science total (140)
Answers
Answer:35%
Step-by-step explanation:
So I’m not sure this is high school math because i’m still in grade school but...
So what you have to do is make a ratio
so if 70 students out of 200 in college prefer history the ratio should be 70 to 200 or 70:200
Then you want to do 70 * 200 which then you get a answer of .35
then to make .35 into a percent you move the decimal two spaces to the left for a answer of 35%
Hope this helps!
A total of 17.5% of students are college students that prefer history.
What is Percentage?Percentage is defined as the parts of a number per fraction of 100. We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.
So the percentage actually means a part per 100.
Percentage is usually denoted by the symbol '%'.
Total number of students = 400
Number of college students that prefer history = 70
Percentage is the division of the required number with the whole.
Percentage of students who are college students that prefer history is,
= (70 / 400) × 100
= 17.5%
Hence the percentage of students who are college students that prefer history is 17.5%.

A city planner wants to build a road parallel to 2nd Ave . What is the slope of the new road?
Answers
Answer:
0
Step-by-step explanation:
The slopes of parallel lines are equal.
Since the slope of the 2nd Ave. line is horizontal, it has no slope.
This means that the new road should also have no slope.
Hope this helps.
The 2nd-eve line is horizontal then the slope of the line will be zero.
What is a slope?Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line. The slope of the line is defined as the ratio of the rise to the run.
Given that a city planner wants to build a road parallel to 2nd Ave. The 2nd eve has the horizontal line.
The slope of the line will be calculated as,
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Slope = ( 0 - 0 ) / ( -4 + 2 )
Slope = 0
Therefore, the 2nd-eve line is horizontal then the slope of the line will be zero.

Step-by-step explanation:
For number 3 you go rise over run. From the point on the y-axis you rise 3 and then run 4 to the x-axis if that makes any sense
1. please start to pay attention
1. an undefined slope is vertical
2. 90-70/15-3 = 20/12 = 10/6 = 5/3
3. 3/4 (rise over run)
4. slope: -1/5 y-intercept: 12
5. 1
6. y = 1/2x +b
3 = 1/2(1) +b
3 = 1/2+b
subtract 1/2 from both sides
2 1/2 = b
y = 1/2x + 2 1/2
