PLS HELP CAN SOMEONE ANSWER B AND C!!! I NEED THE GRAPHS!!! 2. The restaurant bill you and your friend received was not itemized. You ordered 2 drink refills and the egg
breakfast, for a total of $8.40. Your friend ordered 3 refills and the egg breakfast for $9.35.
(a) Write a system of equations for the situation User for the amount charged for a refill and b for the
amount charged for the egg breakfast.
(b) Graph the equations in the system
(c) Use your graph to estimate how much each item cost.
Answer:
Answer:
(a) The system of equations is:
2r + b = 8.40
3r + b = 9.35
(b) The graph is attached down
(c) By using the graph
The cost of the refill is $0.95
The cost of the egg breakfast is $6.5
Step-by-step explanation:
Let r is the amount charged for a refill and b for the amount charged for the egg breakfast
∵ r is the amount charged for a refill
∵ b is the amount charged for the egg breakfast
∵ You ordered 2 drink refills and the egg breakfast, for a total of $8.40
∴ 2r + b = 8.40 ⇒ (1)
∵ Your friend ordered 3 refills and the egg breakfast for $9.35
∴ 3r + b = 9.35 ⇒ (2)
(a) The system of equations is:
2r + b = 8.40
3r + b = 9.35
(b) The graph is attached down
From the graph
The red line represents equation (1)
The blue line represents equation (2)
The two lines intersected at point (0.95, 6.5)
(c) By using the graph
The cost of the refill is $0.95
The cost of the egg breakfast is $6.5

6. Given: angle 1 and angle 2 are supplementary
Prove: p Il a
Answer:
Look at the picture. M angle1= M angle 3 might be wrong
Angle 1 and angle 2 are supplementary, so p and a are parallel by transversal properties and angle congruence.
as it is already stated that Angle 1 and angle 2 are supplementary.
from the angle 2 and 3 are supplementary according to linear pair postulate
Supplementary angles add up to 180 degrees, so we have:
angle 1 + angle 2 = 180
Using the characteristics of parallel lines and transversals, we can determine that if angles 1 and p are complementary and angles 1 and 2 are congruent, then angles p and 2 are also complementary.
according to transitive property of equality
angle1 +angle 2= angle 3+ angle 4
consecutive interior angle theorem
angle 1 = angle 3

A triangle with vertices J(3, 0), K(4, 3), and L(6, 0) is rotated clockwise 90° about the origin. What are the new coordinates for J' K' and L' ?
Answer:
The new coordinates of the triangle J'K'L' are J'(0, -3), K'(3, -4), and J'(6, 0)
Step-by-step explanation:
The given coordinates of the triangle JKL are;
J(3, 0), K(4, 3), L(6, 0)
The rotation of the point of a preimage (x, y) by 90° clockwise gives the point of the image after rotation as (y, -x)
Therefore;
The rotation of point J(3, 0) by 90° clockwise gives J'(0, -3)
The rotation of point K(4, 3) by 90° clockwise gives K'(3, -4)
The rotation of point L(6, 0) by 90° clockwise gives J'(6, 0)
The new coordinates of the triangle J'K'L' are J'(0, -3), K'(3, -4), and J'(6, 0)

Write the formula for the volume of a cone V = 13π r2 h in terms of h.
Find the height h of a cone with volume V = 32π cm3 and radius r = 4 cm.
Formula:
Height:
Answer:
The answer is D, h=3Vπr2. The height of the cone is 6 cm
Step-by-step explanation:
The Height of the Cone is 6 cm.
What is Volume of Cone?The shape's volume is equal to the product of its area and height. = Height x Base Area = Volume.
The formula for the volume of a cone is V=1/3hπr².
Given:
Volume of Cone= 1/3 πr²h
where r is the radius and h is the height.
Now, if V= 32π cm³ and r= 4 cm
Then, Volume of Cone = 1/3 πr²h
32π = 1/3 π(4)²h
32 = 1/3 (4)²h
32= 1/3 (16)h
h/3 = 2
h= 6cm
Hence, the height is 6 cm.

Step-by-step explanation:
i multiplied the S values by the scale factor to get the S dash
The coordinates of the point S' after dilation is S' ( 4 , 2 )
What is Dilation?Resizing an item uses a transition called Dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. Dilation transformations ensure that the shape will stay the same and that corresponding angles will be congruent
Given data ,
Let the triangle be represented as ΔSTU
Now , the coordinates of the triangle are
S ( 2 , 1 ) , T ( 4 , 5 ) and U ( 4 , 1 )
Now , the dilation scale factor is k = 2
So , the coordinates of the triangle after the dilation is
S' ( 4 , 2 ) , T' ( 8 , 10 ) and U' ( 8 , 2 )
Hence , the coordinate of S' is S' ( 4 , 2 )

what is the slope of a line perpendicular to the line whose equation is 2x-y=-6
Answer:
m⊥ = –½
Step-by-step explanation:
First, put the given equation in slope-intercept form:
2x – y = –6
–y = –2x – 6
y = 2x + 6
The slope of the line perpendicular to the line given will be the negative reciprocal of the given line's slope, so:
If m = 2, then m⊥ = its negative reciprocal:
m · –1
2 · –1
–2 → –½
So, the negative reciprocal of 2 is –½.
A ticket to see your favorite baseball team cost $43.32. The price decreases by $0.25 for every game loss during the regular season. What equation could you use to find the cost C of a ticket after L losses? Represent the total change in the cost of a ticket after the team loses 24 games. What is the price of a ticket after the team loses 24 games?
Answer:
$37.82Step-by-step explanation:
Given that the cost of the ticket is
$43.32
and the price decrease is by $0.25
let the cost be C
and let the number of losses be L
the expression for the cost we be
C=43.32-0.25L
for the number of losses which is 22 we have
C=43.32-0.25(22)
C=43.32-5.5
C=37.82
Therefore the price after 22 losses is $37.82

Please help! A line has a slope of -2 and a y-intercept of -3. Graph the line using the slope and y-intercept. Which of the following points lie on this same line? Check all that apply.
Answer:
2. -1.5, 0
3. -6, 9
5. 3, -9
Step-by-step explanation:
Given parameters:
Slope = -2
y - intercept = -3
Unknown:
The point that lies on the line = ?
Solution:
To do the equation of the line,
y = mx + c
y and x are the coordinates
m is the slope
c is the y -intercept
Input the parameters:
y= -2x -3
The points that lie on the line will conform with the equation:
y + 2x = -3
1. -2, 0
y = 0 and x = -2
0 + (-2)2 = -4
2. -1.5, 0
y = 0 and x = -1.5
0 + 2(-1.5) = -3
3. -6, 9
y = 9, x = -6
9 + 2(-6) = 9 - 12 = -3
4. 2, -3
y = -3 and x = 2
-3 + 2(2) = -3 + 4 = 1
5. 3, -9
y = -9, x = 3
-9 + 2(3) = -9 + 6 = -3
6. -4, 4
y = 4 , x - 4
4 + 2(-4) = 4 - 8 = -4
The boldened coordinates line on the same line.
