Answer:
After 20 days, they will have the same number of cards
Step-by-step explanation:
Given;
number of cards with Anthony, = 260 cards
rate of his sale = 5 cards/day
number of cards with Ben, = 100 cards
rate of his purchase, = 3 cards/day
let the number of days when they will have the same number of card = n
set up the linear equation, consider sale as subtraction from the initial value and also consider purchase as an addition to the initial value.
260 - 5n = 100 + 3n
260 -100 = 3n + 5n
160 = 8n
n = 160 / 8
n = 20 days
Therefore, after 20 days, they will have the same number of cards

The perimeter of a triangle is 30 units. If it is dilated with respect to origin by a scale factor of 0.5, what is the perimeter of the resulting triangle?
A. 30 units
B. 20 units
C. 15 units
D. 7.5 units
Answer:
15 unites
Step-by-step explanation:
Given:
perimeter = 30 units
scale factor = 0.5
30 units * 0.50 = 15 units
The perimeter of the resulting triangle is 15 units.
The perimeter of the dilated triangle will be, 15 units.
What is dilation?Dilation means changing the size of an object without changing its shape.
Given that, The perimeter of a triangle is 30 units. If it is dilated with respect to origin by a scale factor of 0.5, we need to find the perimeter of the resulting triangle,
Since, the triangle is with respect to origin by a scale factor of 0.5,
Therefore, the perimeter of the original triangle will be reduced by 0.5 units,
The perimeter of dilated triangle = 30 x 0.5 = 15
Hence, the perimeter of the dilated triangle will be, 15 units.

Evaluate for(+7)-(-3)
Answer:
10
Step-by-step explanation:
When we subtract a negative number, it's basically a double negative, kind of like how we don't use those in English. We want to turn that into a positive, and double negatives are positive.
So, instead of 7-(-3), we get 7+3, or 10
Answer:
10
Step-by-step explanation:
[remember: (+)(+) is (+) itself , (+)(-) is (-) , (-)(-) is (+) ]
(+7)-(-3)
⇒ +7+3
⇒ 10

Step-by-step explanation:
Add six to both sides
x/4=1
Multiply by 4 on both sides
x=4
Regroup.
x/4 - 6 = -5
Add 6 to both sides
x/4 = -5 + 6
Simplify
x/4 = 1
Solve for x
x = 1×4

Can someone help me with this??
Answer:
y= -2x-2
Step-by-step explanation:
All parallel lines have the same slope. So, the line we create must have a slope of -2. If we multiply the x value by -2, we can find b through an equation.
-4 would be x in this case because it's a point we pass.
So, our equation would be
y= -2(-4)+b
y=8+b
Now, we know that y is 8+b. We can find b by plugging in y=6, because those are the coordinates of P.
6=8+b
b=-2
Now we know that b is -2. We put this into the equation for the parallel line and get:
y=-2x-2

Tangela earns the same amount each week by babysitting. When she started this job, she had $200 in her savings account. The table shows Tangela's savings account balance for her first month of work. Week 0 1 2 3 4 Balance $200 $350 $500 $650 $800 Let x represent the number of weeks Tangela has been working and let y represent Tangela's account balance. Which equation, expressed in Slope-Intercept form, represents the amount of money in Tangela's bank account over time?
y=150x+200
y=200x−150
y=150x−200
y=200x+150
Answer:
y=150x+200
Step-by-step explanation:
Given that:
Week : ____ 0___ 1 ___ 2 ____3 _____4
Balance : __200_350 _ 500 _ 650 ___800
Amount had in savings account = $200 before starting the job
x = number of weeks spent working
y = account balance
Slope intercept formula :
y = mx + c
C = intercept ; value of y when x = 0 = 200
m = slope or gradient = change in salary per month (350 - 200 = 500 - 350 = 650 - 500 = 800 - 650 = 150
Hence,
y = 150x + 200
how many solutions does x+2y=8 have?
Answer:
21
Step-by-step explanation:
The given equation is linear with two variables that will have zero solutions.
What is a system of equations?A system of equations, also known as an equation system or a set of simultaneous equations, is a finite set of equations for which common solutions are sought.
Given equation is x + 2y = 8. The equation is a linear equation with two variables. If the equation will have another equation then the solution will have two values for two variables.
If there is only one equation with two variables we will not get any solution we need one more same equation. The equation will have zero solution.

Penguins can swim at a speed of up to 33 ft./s use dimensional analysis to convert the speed to miles per hour 1 mile equals 5280 feet
Answer:
v = 22.5 miles/hour
Step-by-step explanation:
It is given that,
The speed of Penguins is 33 ft/s.
We need to convert the speed to miles per hour.
We know that, 1 mile = 5280 feet
Speed,
[tex]v=33\ \dfrac{ft}{s}\\\\=33\times \dfrac{\dfrac{1}{5280}\ \text{miles}}{\dfrac{1}{3600}\ \text{hour}}\\\\=22.5\ \text{miles/hour}[/tex]
So, the speed of the Penguins is 22.5 miles/hour.

1) Determine Domain of graph below in interval notation
A.D=[-5,5] B.D=[-5,5) C.D=(-5,5) D.D=(-5,5]
2) Determine Range of graph below in set builder notation
Answer: 1) D 2) B, A 3) A
Step-by-step explanation:
Domain is the x-values
Range is the y-values
Graph is a function if no x-values are duplicated
1) option D
(3, 7), (1, 0), (8, 1), (-4, -3), (2, 7)
↓ ↓ ↓ ↓ ↓
Domain: x = {1, 1, 8, -4, 2} → No duplicates so it is a function.
(3, 7), (1, 0), (8, 1), (-4, -3), (2, 7)
↓ ↓ ↓ ↓ ↓
Range: y = {7, 0, 1, -3} 7 is a duplicate so only needs to be listed once
2) Domain = option B, Range = option A
x-values are between -5 (included = bracket) and +5 (not included = parentheses)
y-values are between -5 (included = bracket) and +5 (included = bracket)
3) option A
Domain: x = {1, 4, 5, 7, 9} → 4 matches to both 5 and 7 so is NOT a function
Range: y = {3, 5, 7, 8}
