Answer:
Can't read the picture. Please take a bigger picture of the triangle.
Answer:
x^2 - xy + 1
Step-by-step explanation:
x^2 - xy + 2x/2x
2x/2x = 1
x^2 - xy + 1
This is the furthest we can simplify this expression with the given information.
Answer:
2/5
Step-by-step explanation:
C is at the second tick of 6 segements, so C = 2/6 = 1/3.
If we convert all fractions to /60, you can easily see the answer:
1/3 = 20/60
2/5 = 24/60
1/4 = 15/60
1/5 = 12/60
So we're looking for an answer larger than 20/60, which is only 24/60, a.k.a. 2/5.
Remark
The equation is job1/ time + job2/time = job3/time
Discussion
job one is the time it takes one of the workers to complete the job.
job two is the time it takes the other workers to complete the job
job three is the time it takes to do the job together.
Givens.
Let Marcus's time = m
Let Tony's time be =t
Let their together time = t1
Equation Substitution and solution.
1/m + 1/t = 1/t1
1/6 + 1/4 = 1/t1 The common denominator on the left is 12.
2/12 + 3/12 = 1 / t1
5/12 = 1/t1 Cross multiply.
5*t1 = 12 Divide by 5
t1 = 12/5
t1 = 2 2/5
t1 = 2.4 hours
Cost
1 hour = 43 dollars for labor.
2.4 hours = x dollars for labor.
1*x = 43 * 2.4
x = 103.2 dollars. <<<<< Answer
Answer: y<1x-2
Step-by-step explanation:
Find some coordinates on the line to write a slope intercept form equation for the line and turn it into inequality.
First we need to find the slope and the y-intercept. The y intercept is when x is 0 and as we can see it already indicates that the y intercept is -2 .
(0,-2)
(2,0) Use these points o the find the slope.
0- 2 = -2
-2 -0 = -2
-2/-2 = 1 The slope is one so the equation will be y = 1x - 2 But since this is not an inequality we have to change the equal to sign to an inequality sign.
Looking at the line, it is a dashed line so the inequality sign will be > or <
The painted side of the graph represents the solutions of the graph and that is all underneath the graph so the inequality will be y < 1x-2
