Write the equation of the line in slope intercept form that passes through the point (4,7) and is parallel to y = -7x + 8.
Answer:
y= -7x + 35
Step-by-step explanation:
(y - 7) = -7(x - 4)
y-7 = -7x + 28
y = -7x + 35

Answer:
Step-by-step explanation:
Im guessing its telling you to solve using substitution ?
Well your lucky, most of the work is already done :D
you know y=x-7 , so just replace y with (x - 7) in the other equation
4x - 7(x-7) = 10
4x - 7x + 49 = 10
-3x = -39
x = 13
Now just plug X in the original equation to fine Y
y = x - 7
y = 13 - 7
y = 6
so the solution would be
(13,6)

A grab-bag contains 30 packages worth $.65 each, 10 packages $.60 cents each, and 15 packages worth $.30 each. What is the expected value if you have to pay $.50 to pick one package at random?
Answer:
Expected value of package = $0.04 (Approx.)
Step-by-step explanation:
Given:
30 packages at $0.65 each
10 packages at $0.60 each
15 packages at 0.30 each
Pick up price for random one = $0.50
Find:
Expected value of package
Computation:
Total cost of 30 package = 30 x 0.65
Total cost of 30 package = $19.5
Total cost of 10 package = 10 x 0.60
Total cost of 10 package = $6
Total cost of 15 package = 15 x 0.30
Total cost of 15 package = $4.5
Total cost = 19.5 + 6 + 4.5
Total cost = $30
Cost of random package = 30 / [30+10+15]
Cost of random package = $0.54
Expected value of package = 0.54 - 0.50
Expected value of package = $0.04 (Approx.)

At a team meeting, 80% of the tennis team was there. If there were 12
people at the meeting, how many
people are on the team?
Answer:
15 people
Step-by-step explanation:
let x=total # of people on the team
80%=12
80/100=12/x
cross multiply
80x=1200
division property of equality (divide both sides by 80)
x=15
There are 15 people on the team.

Ice cream cones cost $1.10 and sundaes cost $2.35. One day, the receipts for a total of 172 cones and sundaes were $294.20. How many cones were sold.
Answer:88
Step-by-step explanation:
1.10c+2.35s=294.20
C+S=172
1.10c+2.35s=294.20 if you multiply by 100.
110c+235s=29420
-110 (cones + sundaes =172)
-110c-110s=-18920
125s/125=10500/125
S= 84
C+84=172
-84. -84
C= 88
Dog food bad contains 18 cups to fill it up his friend dog eats 1 1/2 each day he says he'll be able to feed his dog for 27 days that true?
Answer:
It's not true because 18 cups will only last 12 days, not 27 days.
Step-by-step explanation:
1 1/2 = 3/2
3/2(27) = 40.5 cups
18 = 3/2c
c = 12
Does (1, 10) make the inequality y < 8x + 2 true?
Answer:
This is false. (1, 10) is not a solution of this inequality
Step-by-step explanation:
Copy down the inequality:
y < 8x + 2
Now substitute 10 for y and 1 for x:
10 < 8(1) + 2 or 10 < 8 + 2
This is false. (1, 10) is not a solution of this inequality
Answer:
False is the answer.

A frog can hop at a maximum speed of about 60 feet every 4 seconds. How far can the frog go in 30 seconds?
Answer:
450 feet
Step-by-step explanation:
60ft = 4 seconds
x ft = 30 seconds
(cross multiply)
60 * 30 = 4x
1800= 4x
(divide both sides by 4)
x= 1800/4= 450
Answer:
ur answer would be 450 feet

Write the equation of the line that passes throught the points (-1, 6) and (5, -4).
Answer:
y = -5/3x + 13/3
Step-by-step explanation:
(-1, 6) and (5, -4).
First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(-4 - 6) / (5 - (-1))
Simplify the parentheses.
= (-10) / (5 + 1)
= (-10) / (6)
Simplify the fraction.
-10/6
= -5/3
This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.
y = -5/3x + b
To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (5, -4). Plug in the x and y values into the x and y of the standard equation.
-4 = -5/3(5) + b
To find b, multiply the slope and the input of x(5).
-4 = -25/3 + b
Now, add 25/3 to both sides to isolate b.
-4 ⇒ -12/3
-12/3 + 25/3 = 13/3
13/3 = b
Plug this into your standard equation.
y = -5/3x + 13/3
This is your equation.
Check this by plugging in the other point you have not checked yet (-1, 6).
y = -5/3x + 13/3
6 = -5/3(-1) + 13/3
6 = 5/3 + 13/3
6 = 18/3
6 = 6
Your equation is correct.
Hope this helps!

i need a bit of help with this bc i’m literally not smart. no work needed, just an answer. i’ll give brainliest.
Answer:
1. y= -2
Step-by-step explanation:
i hope this helps :)
Answer:
option (3)
Step-by-step explanation:
The equation of a vertical line parallel to the y- axis is
x = c
where c is the value of the x- coordinates the line passes through.
The line passes through (- 2, - 5 ) and (- 2, - 4) with x- coordinates - 2 , then
x = - 2 ← equation of line

Ms. Benson can pay $293.22 for her gym membership upfront, or she can pay the amount over a period of six months. How much would Ms. Benson pay each month for the sixth month period?
Answer:
She would have to pay $48.87 a month for six months.
Step-by-step explanation:
293.22 ÷ 6 = 48.87
Answer:
$48.87
Step-by-step explanation:
For example, if it was a backruptcy we would need to get the principal amount using the simple interest formula.
Interest = Principal * interest rate * term
180 = P * 2% * 1
180 / 2% = P
9,000 = Principal
Benson pays an additional interest of 9,000 each year. Monthly payment of 750.
9,000 / 12 months = 750 per month.
But since we are just dividing the answer will be 293.22 ÷ 6 = 48.87
A number x added to a number y is equal to 100. The number y is also equal to 10 more than the number x doubled. Write and solve a linear system to find the value of x and y.
Answer: x + y=100---equation 1
y =10+ 2x-----equation 2
x=30, y=70
Step-by-step explanation:
Given that
x added to a number y is equal to 100 which means that
x + y=100
and also that
y is also equal to 10 more than the number x doubled which is
y =10+ 2x
we have the linear systems to solve the equations as
x + y=100---1
y =10+ 2x-----2
Solving
Putting the value of y =10+ 2x in equation 1
x +10+ 2x =100
10+3x=100
3x=100-10
x=90/3=30
x=30
y=10 +2x = 10+2x30 =70
?/1 A box contains 5 red marbles and 7 green marbles. Find the probability of drawing a green marble and not returning it to the box and then drawing a red marble?
Answer: 35/132
Step-by-step explanation:
probability of drawing green marble: 7/12
since the green marble drawn won't be returned to the box, the new total amount of marbles in the box is 11.
probability of red marble: 5/11
then multiply the 7/12 and 5/11 together:
35/132 which is abut 26.5%
