which function is represented by the values in the table below?
Some systems of inequalities can have no solution.
Answer:
Yes, that is true.
Step-by-step explanation:
The bounded regions of the two inequalities do not overlap, so there is no solution set. However, the existence of parallel lines does not necessarily indicate that there is no solution, it just means that there is the possibility of no solutions.

rewrite using a single positive exponent
Answer:
9³
Step-by-step explanation:
We need to find the value of [tex]\dfrac{9^5}{9^2}[/tex].
We know that,
[tex]\dfrac{x^a}{x^b}=x^{a-b}[/tex]
Here, a = 5 and b = 2.
So,
[tex]\dfrac{9^5}{9^2}=9^{5-2}\\\\=9^3[/tex]
So, the answer to the given expression is 9³.

1) A straight line is perpendicular to y=2x+5 and passes through (0,3).
What is the equation of the line??
2) A straight line is perpendicular to y=0.5x+3 and passes through (3,5).
What is the equation of the line??
3) A straight line is perpendicular to y=4-5x and passes through (20,5).
What is the equation of the line??
Answer:
See explanations below
Step-by-step explanation:
We are going to be using the point slope form of equation of a line for all the question, This is expressed as;
y-y0 = m(x-x0)
1) For a straight line is perpendicular to y=2x+5 and passes through (0,3).
Slope of the line m = 2
Slope of the line perpendicular M = -1/m
M = -1/2
Substituting M = -1/2 and the point (0,3) into the equation
y-y0 = m(x-x0)
y - 3 = -1/2(x-0)
y-3 = -x/2
2(y-3) = -x
2y-6 = -x
-x-2y = -6
x+2y = 6
The required equation is x+2y = 6
2) For a straight line is perpendicular to y=0.5x+3 and passes through (3,5).
Slope of the line m = 0.5
Slope of the line perpendicular M = -1/m
M = -1/0.5
M = -2
Substituting M = -2 and the point (3,5) into the equation
y-y0 = m(x-x0)
y - 5 = -2(x-3)
y-5 = -2x+6
y+2x = 6 + 5
y+2x = 11
The required equation is y+2x = 11
3) A straight line is perpendicular to y=4-5x and passes through (20,5).
Slope of the line m = -5
Slope of the line perpendicular M = -1/m
M = -1/-5
M = 1/5
Substituting M = -2 and the point (20,5) into the equation
y-y0 = m(x-x0)
y - 5 = 1/5(x-20)
5(y-5) = x-20
5y-25 = x-20
5y-x = -20+25
5y-x = 5
The required equation is 5y-x = 5

please help due soon
Answer:
x = -4
y = -25
Step-by-step explanation:
Since one of the equations is already set with one variable as the subject ( y = 7x + 3) substitute that into the one below it:
9x - 2y = 14
9x - 2(7x + 3) = 14
9x - 14x - 6 = 14
-5x = 20
x = -4
Substitute this into one of the equations and solve for the other variable:
y = 7x + 3
y = 7(-4) + 3)
y = -28 + 3
y = -25
hope this helps!
Answer:
(- 4, - 25 )
Step-by-step explanation:
Given the 2 equations
y = 7x + 3 → (1)
9x - 2y = 14 → (2)
Substitute y = 7x + 3 into (2)
9x - 2(7x + 3) = 14 ← distribute and simplify left side
9x - 14x - 6 = 14
- 5x - 6 = 14 ( add 6 to both sides )
- 5x = 20 ( divide both sides by - 5 )
x = - 4
Substitute x = - 4 into (1) for corresponding value of y
y = 7(- 4) + 3 = - 28 + 3 = - 25
solution is (- 4, - 25 )

find the measure of angle 8
Answer: 18
Step-by-step explanation:
First we need to solve for x to find the measure of the adjacent angle.
-6x+64 = 8x + 162
subtract 162 to leave x by itself
-6x- 98 = 8x
add 6x to both sides
-98 = 14x
now divide by 14
x = -7
Now solve one of the given equations to find the measure of the adjacent angle.
8(-7)+162
-56 + 162 = 106
Meaning the measure of angle 8 is 18
because they'll add up to 180(The measure of the line)
Answer:
measure of angle 8 is 16 6/7
Step-by-step explanation:
-6x+64=8x+62 because there is a transversal.
2=14x
x=2/14
so, now you have to find 8x+162. 163 1/7 degrees. (Plug in variables)
measure of the angle we just found + measure of angle 8 is 180 degrees.
(straight line definition) so 180-163 1/7= 16 6/7
measure of angle 8 is 16 6/7
does this represent a function?

Find the number of square inches in one square foot.
144
12
24
think of this as finding the area of a box. if each side of the box is one foot long, or 12 inches long, you need to multiply length times width to find the square inches. in this case it would look like:
A= 12in x 12in
12in x 12in = 144in^2
A = 144 in^2
therefore there are 144 square inches in one square foot.
Answer:
it is 144

Which expression is equal to
Answer:
D
Step-by-step explanation:
Rosa loves to run. She set a goal to run greater than 490 miles this year. To date, she has run 145 miles. If she begins to run 15 miles per week, how long will it take Rosa to reach her goal?
Write an inequality, using x as the variable, that represents this situation.
Answer:
Step-by-step explanation:
145+15x>490. subtract 145 from both sides
15x>345, divide both sides by 15
x>23
So she will need to run for more than 23 weeks to reach her goal.
