Answer:
[tex]y = mx + c \\ 3 = - 2(0) + c \\ c = 3 \\ y = - 3x + 3[/tex]
Answer:
y =-2x+3
Step-by-step explanation:
The y intercept is 3 ( the y intercept is when x =0)and the slope is -2
The slope intercept form is y = mx+b where m is the slope and b is the y intercept
y =-2x+3

If a, b, and c are solutions to the
equation 3x3 – 25x2 - 50x = 0 and
a < b < c, evaluate 10c – 6a.
Answer:
[tex]\displaystyle 10c - 6a = 110[/tex]
Step-by-step explanation:
We are given the equation:
[tex]\displaystyle 3x^3 - 25x^2 -50x = 0[/tex]
Where a, b, and c are solutions to the equation and where a < b < c, we want to determine the value of 10c - 6a.
To find the solutions of the equation, we can factor:
[tex]\displaystyle \begin{aligned} 3x^3 - 25x^2 -50x & = 0 \\ \\ x(3x^2 - 25x -50) & = 0 \\ \\ x(3x+5)(x-10) & = 0 \end{aligned}[/tex]
From the Zero Product Property:
[tex]\displaystyle x = 0 \text{ or } 3x + 5 = 0 \text{ or } x - 10 = 0[/tex]
Solve for each case:
[tex]\displaystyle x = 0 \text{ or } x = -\frac{5}{3} \text{ or } x = 10[/tex]
We can see that -5/3 < 0 < 10. Thus, a = -5/3, b = 0, and c = 10.
Therefore:
[tex]\displaystyle \begin{aligned} 10c - 6a & = 10(10) - 6\left(-\frac{5}{3}\right) \\ \\ &= 100 + 10 \\ \\ & = 110 \end{aligned}[/tex]
Janet worked 3 hours more than David and 7 hours less than Kate. David earned $7.50 per hour, Janet earned $6 per hour, and Kate earned $9 per hour. If Kate earned $27 more than David and Janet combined, how much did each person earn?
We want to write and solve a system of equations to see how much each person earns.
What each one earned is:
Janet = $78Kate = $180David = $75Let's define:
J = number of hours that Janet worked.D = number of hours that David worked.K = number of hours that Kate worked.The information is:
"Janet worked 3 hours more than David and 7 hours less than Kate"
From this we can write:
J = D + 3
J = K - 7
We know that:
David earned $7.50 per hour.Janet earned $6 per hour.Kate earned $9 per hour.Finally, we know that Kate earned $27 more than David an Janet combined, then we can write:
$9*K = $27 + ($7.50)*D + $6*J
Then we have a system of equations:
J = D + 3
J = K - 7
$9*K = $27 + ($7.50)*D + $6*J
We can rewrite the first and second equations to get:
D = J - 3
K = J + 7
Now we can replace these two in the other equation to get:
$9*(J + 7) = $27 + ($7.50)*(J - 3)+ $6*J
Now we can solve this for J:
$9*J + $63 = $27 + $7.50*J - $22.50 + $6*J
$9*J - $7.50*J - $6*J = $27 - $63 - $22.50
-$4.50*J = -$58.60
J = (-$58.60)/(-$4.50) = 13
This means that Janet worked for 13 hours.
And with:
K = J + 7 = 13 + 7 = 20
D = J - 3 = 13 - 3 = 10
We can see that Kate worked for 20 hours and David for 10 hours.
Then each one of them earned:
Janet = 13*$6 = $78
Kate = 20*$9 = $180
David = 10*$7.50 = $75

Billy has 1 gallon of paint he’s going to pour it into a paint tray that measures 10 inches wide 14 inches long and 4 cm deep which of the following scenarios would happen
Answer:
Lets see if the gallon fill the paint tray or not.
For that purpose we need to find out the volume of the paint tray and compare it with the volume of the gallon.
Given:
Length = 14 inches
Width = 10 inches
Depth = 4 cm = 1.57 inches
Volume = length x width x depth
Volume = 14 x 10 x 1.57
= 220.47 inches cube
Volume of Gallon = 231 inches cube
Comparing the two volumes:
231 inches cube - 220.47 inches cube = 10.52 inches cube
Hence,
The paint will not fill the tray by 10.53 in3.

Answer:
Parallel line, [tex]y=\frac{3x}{2} -\frac{5}{2}[/tex]
Perpendicular line, [tex]y=4-\frac{2x}{3}[/tex]
Step-by-step explanation:
For the parallel line, In the equation y=mx+c, we are trying to find c.
We know that m=[tex]\frac{3}{2}[/tex], so
we have the equation y=[tex]\frac{3x}{2} +c[/tex]
So we substitute the points we are given (3,2) into
[tex]2=\frac{3}{2}*3+c\\Thus, c= \frac{-5}{2}[/tex]
The final equation we get is
[tex]y=\frac{3x}{2} -\frac{5}{2}[/tex]
For the perpendicular line, we need to find the inverse of the slope.
The inverse of the slope [tex]\frac{3}{2} = -\frac{2}{3}[/tex]
So, we use this in our formula and also plug in the same coordinates we were given.
Therefore, we get:
[tex]2= -\frac{2}{3}*3+a\\a=4\\\\y=4-\frac{2x}{3}[/tex]

b)
Solve the equation.
Answer:
x = 6
Step-by-step explanation:
let the number be x , then
3x + 4 = 22 ( subtract 4 from both sides )
3x = 18 ( divide both sides by 3 )
x = 6
The unknown number is 6
Answer:
a). x3 + 4 = 22

Answer:
∠ 1,3,5,7 = 32°
∠2,4,6,8,= 148°
Step-by-step explanation:
From the figure attached,
AB and CD are two parallel lines and another transverse line is intersecting these line at two distinct points.
Since, m∠1 = 32°,
∠1 and ∠4 are supplementary angles [Linear pair of angles]
m∠1 + m∠4 = 180°
32° + m∠4 = 180°
m∠4 = 180° - 32°
m∠4 = 148°
therefore,
m∠1,3,5,7 = 32°
m∠2,4,6,8,= 148°

find the unknown angle
Answer:
x = 35 degrees
y = 70 degrees
z = 75 degrees
Step-by-step explanation:
X will equal 35 degrees because that angle is vertical to the 35 degree angle, which means they are equal.
To find the measure of angle z, subtract the outside angle from 180:
180 - 105 = 75
To find the measure of angle y, add the two other known angles of the triangle and subtract that from 180:
35 + 75 = 110
180 - 110 = 70
Answer:
x = 35, y=75, z=70
Step-by-step explanation:
I dont know which angle you wanted exactly. However x is equal to 35 (I'm sorry, I forgot the name of the rule that makes that way, I assume it's in your notes if this is for a class). Z is equal to 75 because a straight line(the one on the bottom) is equal to 180 degrees. Since you have an angle on that line already (105), just subtract 180-105 to get 75.
Lastly, since we have x and z now, we can add them and subtract from 180(the degree in a triangle. So 35+75 = 110 and 180-110 = 70.

Write a system of equations to describe the situation below, solve using elimination, and fill in the blanks.
The box office at a theater is selling tickets for a series of rock concerts. So far, they have sold 98 balcony tickets and 26 general admission floor tickets for Friday's show, for a total of $4,524 in receipts. For Saturday's show, 74 balcony tickets and 96 general admission floor tickets have been sold, equaling $5,478 in receipts. How much does each ticket cost?
The box office sold 360 tickets to a concert at
the college. The total receipts were $4,170. General
admission tickets cost $15 and student tickets cost $10.
How many of each kind of ticket was sold?
Answer: 114 general admission tickets and 246 student tickets were sold.
Step-by-step explanation:
Let x represent the number of general admission tickets that were sold.
Let y represent the number of student tickets that were sold.
The box office sold 360 tickets to a concert at the college. It means that
x + y = 360
General admission tickets cost $15 and student tickets cost $10. The total receipts were $4170. It means that
15x + 10y = 4170- - - - - - - - -1
