Given: 5x + 3 > 4x + 7. Choose the graph of the solution set.

Answers

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

5x+3 > 4x+7

solve for x

Group terms that contain the same variable, and move the constant to the opposite side of the inequality

5x-4x > 7-3

x> 4

The solution is the interval-------> (4,∞)

All real numbers greater than 4

The solution is the shaded area to the right of the vertical dashed line

see the attached figure

Let's solve your inequality step-by-step.

5x+3>4x+7

Step 1: Subtract 4x from both sides.

5x+3−4x>4x+7−4x

x+3>7

Step 2: Subtract 3 from both sides.

x+3−3>7−3

x>4

Answer:

x>4

Simplify completely quantity x squared plus 4 x minus 5 over quantity 5 x squared minus 8 x plus 3 times quantity 20 x minus 12 over x squared minus 6 x minus 55 how do I simplify this?

Answers

x2+4x−55x2−8x+3×20x−12x2−6x−55 start by doing some factoring (x+5)(x−1)(x−1)(5x−3)×4(5x−3)(x−11)(x+5)

cancel common factors and then see whats left...

So you cancel (x+5) and 4(5x-3)?

Your CORRECT answer is:

a. quantity x minus 5 over quantity x plus 1, x ≠ −1, x ≠ −9

THIS IS 100% CORRECT!!!

By looking at linear equations we can tell how they will interact in the coordinate plane. What are possible if two linear equations are graphed?. . a.They could be parallel to each other..
b.They could intersect at two points..
c.They could be perpendicular to each other..
d.They could be skew lines..
e.They could be the same line.

Answers

The correct answers are options:

a. They could be parallel to each other.

c. They could be perpendicular to each other

e. They could be the same line.

Explanation:

Two lines are parallel if they do no intersect each other any point. Such lines have same slopes and the cross the y axis at different points.

Two lines can intersect either at one point or they intersect at infinite number of points. Second case occurs when both equations represent the same line so we say that the two equations have infinite number of solutions as each point will satisfy both the equations.

Two line can be perpendicular if they are at right angle to each other. This means a right angle is formed at their point of intersection. The slope of such lines is negative reciprocal of each other.

Skew lines can occur only in 3D. Two lines are skew lines if they are neither parallel nor they intersect each other at any point. Such condition can not be achieved when two linear equations are graphed on the coordinate axis.

Two equations can represent the same line when one equation is obtained by multiplying the second equation by a constant number. In this case the two equations have infinite number of solutions.

Answer:
A ) they could be parallel to each other
C ) they could be perpendicular to each other
E ) they could be the same line.
Two lines could intersect at one point and skew lines are not in the same plane.

The lengths of two sides of a triangle are 12 inches and 4 inches. Which of the following dimensions is the third side of this triangle?9 inches
8 inches
7 inches
6 inches

Answers

According to the rule that any 2 shorter sides have to be longer (not equal) to the other side, the answer is 9 inches.

4 + x > 12
x > 8

The answer is 9 inches, as x>8 doesn't include 8 in its domain.

What should be done to both sides of the equation in order to solve N/4 = -12.4

Step-by-step explanation:

Mike and Kate plan to save money for their wedding over a 20 month period. They will need to save $8,000 to help pay for the wedding. They set aside the same amount each month. After a year they saved $4,000. Mike and Kate know they must adjust their plan in order to meet their goal, so they came up with the following options:Option A: Stay with saving the same amount they've been saving each month but postpone the wedding 2 months.
Option B: Increase the amount of money they save each month by $80 from what they've been saving.
Which of the following is a true statement?
a.
Only option A will allow them to meet their goal.
b.
Only option B will allow them to meet their goal.
c.
Both options A and B will allow them to meet their goal.
d.
Neither option A nor option B will allow them to meet their goal.



Please select the best answer from the choices provided


A
B
C
D

Answers

D is the correct answer. Mike and Kate require $8000 for their wedding and have saved $4000 already, so they need a further $4000. They have saved the money over 12 months, which means they have been saving $333.33 every month (4000/12). In Option A they have 10 months to save money - the original 8 months, plus the 2 months the wedding is postponed. This will give them the chance to save $3333.33 (333.33 x 10). In Option B, they can increase their monthly savings by $80, giving them total monthly savings of $413.33 (333.33 + 80). In the remaining 8 months before the wedding, they will be able to save $3306.66 (413.33 x 8). However, neither of these options give them the $4000 required to make their $8000 budget.

d
