Answer:
y=1x+1
Step-by-step explanation:
We already know the Y intercept is 1 from the first set of points given
The change in x is 2 and the change in Y is also 2 so when you make the slope equation y/x you get 1
Pluggin in the numbers you get: y=1x+1

A is the midpoint of BC. C is the midpoint of AD. E is the midpoint of CD. If CE =
3ft, how long is BD?
Answer:
18ft
Step-by-step explanation:
AC = CD = BA
CD = 2CE
BD = BA + AC + CD = 2CE + 2CE + 2CE
= 6CE
CE = 3
6 × 3 = 18
a $260 suit price is marked down 10 % find the sale price
Answer:
260*0.90=sales price=234
Step-by-step explanation:
Step-by-step explanation: We first need to find the discount.
The formula for discount is shown below.
Original Price × Rate of Discount = Discount
So here, the original price is $260 and the
rate of discount is 10% off which we can write as .10.
So we multiply 260 by .20
260 x .10 gives us 26.
So the discount is $26.
Now let's find the sale price.
The formula for sale price is shown below.
Original Price - Discount = Sale Price
Since the original price is $260 ad the discount is $26,
we have 260 - 26 which gives us 234.
So the sale price of the suit is $234.

Find the slope of the line through the points (13, 15) and (13, 19). Then find the slope of the line parallel and the line perpendicular.
We must find the slope of the original line using slope formula*.
[tex]m = \frac{19 - 15}{13 - 13} = \frac{5}{0} = 0[/tex]
Because the given points have the same x-coordinate, the slope is 0.
Given that the original line doesn't have slope, the other two lines won't have one either.

Here is parallelogram ABCD:
Prove segment is AM congruent to segment CM.
Plz help me it’s due today
The proof of AM being congruent to CM is as follows:
Given that,
ABCD is the ║gm
Diagonals AC and BD with M as the intersection point.
To prove:
AM ≅ CM
Proof:
In ΔAMD and ΔBMC,
∠M = ∠M (∵ Common)
AD = BC (∵ opposite sides of ║gm are equal)
∠ADM = ∠CBM (∵ Alternate angle)
∵ ΔAMD ≅ ΔBMC
Thus, AM ≅ CM (using AAS property).

2 after a long morning of sledding, Mrs.Fieldhouse made a batch of hot cocoa for her daughter and neighborhood friends. She divided it among 8 mugs. Each mug has more than 9 fluid ounces of hot cocoa. Write an inequality to describe the situation
Answer:
[tex]\frac{x}{8}>9[/tex]
Step-by-step explanation:
step one:
given
we can say that the total amount of cocoa made by Mrs.Fieldhouse is
x ounces
Step two:
Since the total batch which is x ounces was divided into 8 mugs
then the expression is x/8
The inequality for the situation is
[tex]\frac{x}{8}>9[/tex]
Ryan is choosing between two exercise routines. In Routine #1, he burns 22 calories walking. He then runs at a rate that burns 10.5 calories per minute. In Routine #2, he burns 39 calories walking. He then runs at a rate that burns 6.25 calories per minute.
Complete question :
Ryan is choosing between two exercise routines. In Routine #1, he burns 22 calories walking. He then runs at a rate that burns 10.5 calories per minute. In Routine #2, he burns 39 calories walking. He then runs at a rate that burns 6.25 calories per minute. For what amounts of time spent running will Routine #1 burn at most as many calories as Routine #2?
Answer:
4 minutes
Step-by-step explanation:
Given the following exercise routines :
Routine #1,
Walking : burns 22 calories walking. He then running : burns 10.5 calories per minute.
Routine #2,
Walking : burns 39 calories walking. He then running : burns 6.25 calories per minute.
Let number of tone spent running = t
Hence,
Routine 1 ; calories burned
22 + 10.5t
Routine 2 ; calories burned
39 + 6.25t
Equating the two equations :
22 + 10.5t = 39 + 6.25t
10.5t - 6.25t = 39 - 22
4.25t = 17
t = 17/4.25
t = 4

Rachel saved money to buy art supplies. She used 13 of her savings to buy brushes. She used 35 of her savings to buy paint. What fraction of her savings does she have remaining?
Given:
Rachel used [tex]\dfrac{1}{3}[/tex] of her savings to buy brushes.
She used [tex]\dfrac{3}{5}[/tex] of her savings to buy paint.
To find:
The fraction for remaining savings.
Solution:
Fraction that Rachel used of her savings to buy brushes and paint is
[tex]\text{Fraction for used amount}=\dfrac{1}{3}+\dfrac{3}{5}[/tex]
[tex]=\dfrac{5+9}{15}[/tex]
[tex]=\dfrac{14}{15}[/tex]
Now,
[tex]\text{Fraction for remaining savings}=1-\text{Fraction for used amount}[/tex]
[tex]\text{Fraction for remaining savings}=1-\dfrac{14}{15}[/tex]
[tex]\text{Fraction for remaining savings}=\dfrac{1}{15}[/tex]
Therefore, [tex]\dfrac{1}{15}[/tex] of her savings is remaining.

What is 3.5=12s-55
Answer:
4.875 = s
Step-by-step explanation:
3.5=12s-55
Add 55 to each side
3.5+55=12s-55+55
58.5 = 12s
Divide each side by 12
58.5/12 = 12s/12
4.875 = s
Answer:
s = 4.875
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
3.5 = 12s - 55
Step 2: Solve for s
Add 55 to both sides: 58.5 = 12sDivide 12 on both sides: 4.875 = sRewrite: s = 4.875Step 3: Check
Plug in s into the original equation to verify it's a solution.
Substitute in s: 3.5 = 12(4.875) - 55Multiply: 3.5 = 58.5 - 55Subtract: 3.5 = 3.5Here we see that 3.5 does indeed equal 3.5.
∴ s = 4.875 is a solution of the equation.
Calvin Butterball earns $400 working at the supermarket to help pay his share of a vacation trip with Phoebe Small's family. To supplement his earnings, Calvin's mother will give him an additional 20% of what he earns and his father will give him an additional 30% of what he earns. a. How much will he get from each parent?
Answer:
Mother = $80
Father = $120
