Remark
I hope you don't mind if I laughed a little at the graph. The y intercept of the line is at 10 dollars, but the rental car has not moved an inch. I guess they're charging you to look at your driver's license. It's late, and maybe I am a little giddy.
Begin by using a ruler (or some other straight edge) to join all the dots.
a) I'll spend a little time here. It is very important that you know how to read a chart and this question is your first step. The question is how many dollars does it take to go 40 miles? There is a system. Start with the 40 miles on the horizontal axis (x axis if you know that that is).
Use a ruler to go straight up until you hit the line.
When you hit the line, mark the place.Now move straight across until you hit the y axis where you find out the money.You should get 30 dollars.b) This question is a guess.
You can find the 70 dollars easily enough. Go straight up again until you hit the line. Mark the point on the line.Go straight across again.Not so easy. It isn't marked. You have to make a guess. My guess is 45. What do you think?c) This question is the exact reverse of the other two.
This time you start with the amount of moneySo you start at 60 dollars and go straight across until you hit the line.Mark the point.Now take your ruler and go straight down. You should hit 100 miles.solve for 6xsquare-x-2<0
Answer:
-x-2<0-x=2x= -2hope it helps.
Answer:
[tex]\frac{-1}{2} <x<\frac{2}{3}[/tex]
Step-by-step explanation:
6x² - x - 2 < 0
6x² - 4x + 3x - 2 < 0
(6x² - 4x) + (3x - 2) < 0
2x(3x - 2) + (3x - 2) < 0
(3x - 2)(2x + 1) < 0
[tex]\left \{ {{3x - 2<0} \atop {2x + 1>0}} \right.[/tex]
[tex]\left \{ {{3x<2} \atop {2x>-1}} \right.[/tex]
[tex]\left \{ {{x<\frac{2}{3} } \atop {x>\frac{-1}{2} }} \right.[/tex]
Cheddar cheese cost 5.25$ per pound. Which equation best represents y, the total cost of x pounds of cheddar cheese? Best answer gets brainlist
Answer: y = 5.25x
Step-by-step explanation:
The cost of one pound of cheddar cheese is $5.25.
The number of cheese purchased is x.
The total cost of cheese would therefore be the cost of one pound of cheese multiplied by the number of pounds of cheese purchased:
= 5.25 * x
Full expression is therefore:
y = 5.25 * x
y = 5.25x

if u don't want them to have your insta/snap, tell them that you don't like sharing them. I just wouldn't respond after that
If they are bothering you say "Thank you for being nice to me, I am going to say this in the most the nicest way possible, but you're kind of bothering me right now. If you keep messaging me/ bothering me I'm going to have to block you" or you could say "Please stop asking me for my insta/snap if you keep asking me I am going to have to block you. Thank you have a nice day :)"

what is the length of the hypotenuse,c ? 3m 5m
Answer:
square root of 34
Step-by-step explanation:
ok so S is for Squared
Cs= As+Bs
5s+3s= Cs
25+9=34
Cs=34
C= square root of 34
to get C we need to square root Cs
square root of 34
so C is 5.83

The variable g represents the number of guests, and the variable c represents the cost in dollars. If there are 10 guests, how much will Anne's retirement party cost? $
Answer:
Cost (10 guests ) = 50
Step-by-step explanation:
Given : Cost c = 10 + 4g (g refers to guests)
Equation : c = 10 + 4g
Putting no. of guests 'g' = 10
c = 10 + 4 (10) = 10 + 40
c = 50
For each expression, write an equivalent expression that uses only addition: a. 20 - 9 + 8 - 7 b. 4x - 7y - 5z + 6 c. -3x - 8y - 4 - 8/7z
Answer:
a. =11+ 1
b. =4x+ (-7y) + (-5z) +6
c. (-3x) + (-8y) +(-4)+(-8/7z)
Step-by-step explanation:
a. 20 - 9 + 8 -7
=11+ 1 ( this is obtained by solving)
b. 4x - 7y - 5z + 6
=4x+ (-7y) + (-5z) +6
We multiply the negative sign with the positive sign to get a minus so the answer remains the same and the expression is written as an addition sum.
c. -3x - 8y - 4 - 8/7z
-[ 3x+8y+4+8/7z]
or
(-3x) + (-8y) +(-4) +(-8/7z)
The minus sign is taken as common leaving the expression with the plus only.
It can be written in the same manner as above, adding the negative terms so that the expression is written as a sum.
The expressions are a sum after the negative sign is marked with the terms. It shows that the negative terms are being added.

Answer:
The median score will stay at 91.
Step-by-step explanation:
First put the numbers in order from greatest to least:
87, 88, 91, 91, 95, 100
Then find the median (middle) because there are two in the middle that are the same, it's just that number.
Next, add the other numbers.
86, 87, 88, 88, 91, 91, 95, 98, 100, 100
Find the median again, which is still 91.

What is the equation in slope-intercept form of the line that crosses the x-axis at 21 and is perpendicular to the line represented by y = 7/2x-13
Given:
A line is perpendicular to the line [tex]y=\dfrac{7}{2}x-13[/tex].
The line passes through the x-axis at 21.
To find:
The equation of the line in slope intercept form.
Solution:
The slope intercept form of a line is:
[tex]y=mx+b[/tex]
Where, m is the slope and b is the y-intercept.
The given line is:
[tex]y=\dfrac{7}{2}x-13[/tex]
So, the slope of this line is [tex]\dfrac{7}{2}[/tex].
The product of slopes of two perpendicular lines is -1.
Let m be the slope of required line. Then the slope of the required line is:
[tex]m\times \dfrac{7}{2}=-1[/tex]
[tex]m=-\dfrac{2}{7}[/tex]
The line passes through the x-axis at 21. It means the line passes through the point (21,0). So, the equation of the line is:
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-0=-\dfrac{2}{7}(x-21)[/tex]
[tex]y=-\dfrac{2}{7}(x)-\dfrac{2}{7}(-21)[/tex]
[tex]y=-\dfrac{2}{7}x+6[/tex]
Therefore, the equation of the required line is [tex]y=-\dfrac{2}{7}x+6[/tex].
Y=190(1.471)^x determine the percentage of increase or decrease
Given:
The exponential function is:
[tex]y=190(1.471)^x[/tex]
To find:
The percentage of increase or decrease.
Solution:
The general exponential function is:
[tex]y=a(1+r)^x[/tex] ...(i)
Where, a is the initial value,t is the time period, r is the rate of increase if [tex]r>0[/tex] and r is the rate of decrease if [tex]r<0[/tex].
We have,
[tex]y=190(1.471)^x[/tex]
It can be written as:
[tex]y=190(1+0.471)^x[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]r=0.471[/tex]
Since [tex]r>0[/tex], therefore the given function is an increasing function.
[tex]r\%=0.471\times 100[/tex]
[tex]r\%=47.1\%[/tex]
Therefore, the percentage of increase is 47.1%.

Which of the following sets of numbers could not represent the three sides of a right
triangle?
{20, 48,52}
{40, 75, 85}
{14, 47,50}
{13, 84, 85}
Answer:
{14, 47, 50}
Step-by-step explanation:
The three sides of a right triangle must satisfy
a² + b² = c², known as the Pythagorean Theorem. So let's put the pairs into the theorem.
20, 48, 52
a² + b² = c²
20² + 48² = 52²
400 + 2304 = 2704
2704 = 2704
20, 48, and 52 represent the three sides of a right triangle.
40, 75, 85
a² + b² = c²
40² + 75² = 85²
1600 + 5625 = 7225
7225 = 7225
40, 75, and 85 represent the three sides of a right triangle.
14, 47, 50
a² + b² = c²
14² + 47² = 50²
196 + 2209 = 2500
2405 ≠ 2500
14, 47, and 50 do NOT represent the three sides of a right triangle.
13, 84, 85
a² + b² = c²
13² + 84² = 85²
169 + 7056 = 7225
7225 = 7225
13, 84, and 85 represent the sides of a right triangle.
14, 47, and 50 do NOT represent the three sides of a right triangle, therefore making it your answer.
