4) The line shown represents the amount of money
left on a gift card, y, after Mina buys lattes. After
buying 2 lattes, she has $2 left. What is an
equation of the line in point-slope form?
Answer:
[tex] y - 2 = -3(x - 2) [/tex]
Step-by-step explanation:
The equation of the line in point-slope form is given by the formula, [tex] y - b = m(x - a) [/tex], where,
(a, b) = coordinates of a point on the line.
[tex] m = slope = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Given that after buying 2 lattes, she has $2 left, this represents a point on the line which is (a, b) = (2, 2). That is, when x = 2 lattes, y = $2.
Let's find the slope using the point (2, 2) and any other point on the line, say at x = 1, when y = 5, that's (1, 5).
[tex] m = slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{5 - 2}{1 - 2} [/tex]
[tex] = \frac{3}{-1} [/tex]
[tex] m = slope = -3 [/tex]
Plug m = -3, a = 2, and b = 2 into point-slope form.
[tex] y - b = m(x - a) [/tex]
[tex] y - 2 = -3(x - 2) [/tex]

Multiply a negative and a positive equals a negative:(-)x(+)=(-)
-(18×3)x
Multiply the numbers

now we do the same thing only different way ok
-54x>x
Move variable to the left hand side and change its sign
-54x-x>0
the same way only different way ok
-54x>x
Move variable to the left by adding its opposite to both sides
-54x-x>x-x
the sum of two opposites equals 0
-54x-x>0
Collect like terms
-55x>0
the same way only different way ok
-54x-x
If a negative term doesn't have a coefficient, it is considered that the coefficient is -1
-54x-1x
Collect like terms by calculating the sum or difference of their coefficients
(-54-1)x
Calculate the difference
-55x
now we do the same thing only different way ok
-54x-y>0
Collect like terms
-55x>0
Divide both sides of the inequality by -55 and flip the inequality sign
x<0
Now we do the same thing only different way ok
-55x>0
Divide both sides of the inequality by-55 and flip the inequality sign
-55x÷(-55)<0÷(-55)
any expression Divided by itself equals 1
x<0÷(-55)

I can add fractions with unlike denominators. 2/5 + 3/10 =
Answer:
7/10
Step-by-step explanation:
2/5 multiply the denominator by 2 which will make it 10. Then multiply the numerator by 2 which will make it 4. So it will be 4/10. Then add 4/10 to 3/0 which makes 7/10.
What is 2/5 of a book to 1/2 of an hour as a unit rate?
Answer: 4/5 book per hour
Step-by-step explanation: in this question, we are to rewrite (2/5)/(1/2) as unit rate.
To write this as a unit rate, what we need to do is to divide 2/5 by 1/2.
That means 2/5 divided by 1/2
Removing the division and replacing with multiplication will give 2/5 * 2/1 = 4/5 books/hour

Solve the system below by substitution.
6x - y = - 23
2x + 5y = -13
Answer:
x= -4 y= -1
Step-by-step explanation:
6x - y = - 23
-y=-23-6x
y=6x+23, use this to plug in for y in the second equation.
2x + 5y = -13
2x + 5(6x+23) = -13
2x+30x+115=-13
x= -4, use this to plug in for x in the first equation.
6x - y = - 23
6(-4)-y=-23
-24-y=-23
-y=-23+24
-y=1
y= -1
The values after solving the equations by substitution is that the value of x is -4 and the value of y is -1.
What is an arithmetic operation?The four fundamental operations of arithmetic are addition, subtract, multiply, and division of two or more numbers. Included in them is the study of integers, especially the order of operations, which is important for all other aspects of mathematics, notably algebra, information management, and geometry.
As per the provided data in the question,
6x - y = -23 (i)
2x + 5y = -13 (ii)
Multiply equation (ii) by 3
6x + 15y = -39 (iii)
Solve equation (i) and (iii)
-16y = 16
y = -1
Substitute y = -1 in equation (i)
6x = -23 - 1
x = -4.

1) The Boateng family has a sickening house whose layout is shown
above. They would like to renovate just bedrooms #2 and 3. Because you
are a contractor, you receive 20% off from Home Depot whenever you
make any purchases. If Home Depot sells your client's ideal wool carpet
for $8.99 per square foot, how much will it cost to carpet both
bedrooms? (Keep in mind that 10'8" would be written as a decimal
approximation of 10.67 ft. Think about why this is.)
a) How many total square feet of carpeting will you need?
Answer:
The cost will be $1662.136
The total square ft of carpeting will be 231.1122ft^2
Step-by-step explanation:
For the bedrooms, the dimension from the image is shown as(see attahced)
Bedroom #2= 10"8' x10"4'
Bedroom #3= 10"8' x11"4'
let us convert all dimension to feet and solve for the area of the bedrooms
Bedroom #2= 10"8' x10"4'
Bedroom #2=10.67x10.33feet
Area of Bedroom #2= 110.2211ft^2
Bedroom #3 = 10"8' x11"4'
Bedroom #3 =10.67x11.33feet
Area of Bedroom #3= 120.8911ft^2
The total area of both rooms is
Total area=110.2211+120.8911
Total area=231.1122ft^2
now the cost of one square floor s $8.99
hence the cost of 231.1122ft^2 will be
Cost of carpet = 231.1122*8.99
Cost of carpet = $2,077.67
Given that, because you are a contractor, you will receive 20% off
therefore it will cost
= (20/100)*2,077.67
=0.2*2,077.67
=$415.534
The cost will now be $2,077.67-$415.534
= $1662.136
Explain whether the points (-13,4), (-7,3), (-1,2), (5,1). (11,0), (17, -1) represent the set of all the solutions for the

No, because the point (17, -1) is not on the line that represents the equation y = a +
O Yes, because all of the points that are listed are on the line y = - +

Give each rate in miles per hour. Round to the nearest tenth.
Dhruv jogs 8 feet per second.
I don’t know the answer please help.
The question requires changing feet per second into miles per hour
The unit rate in miles per hour is 5.5 miles per hour
8 feet = 0.00151515 miles
1 second = 0.000277778 hour
unit rate in miles per hour = number of miles / number of hours
= 0.00151515 mile / 0.000277778 hour
= 5.4545356363714 miles per hour
Approximately, 5.5 miles per hour to the nearest tenth

calculate E, the amount of euros that has the same value as D U.S. dollars, using the equation E=17/20D=
The given equation is: E=17/20 D , where E=amount of Euros and D= amount of U.S dollar.
Now for 1 U.S dollar, we need to plug D=1 into the above equation. So, we will get.........
E=17/20(1)
E=1/20=0.85
0.85 Euros have the same amount as 1 U.S dollar.
