Draw a vertical y-axis on the left-hand side of your graph and label it. Then draw a horizontal
x-axis at the bottom of your graph. Then label the coordinates of each corner of the sign on your graph. Draw line a on your graph. What is the slope of line a?
Answer:
20
Step-by-step explanation:
The line a is an illustration of a linear function
The slope of line a is 1The equation of the line a is y = x + 2How to determine the slope of the line?From the complete figure, we have the following points on line a
(x,y) = (0,2) and (2,4)
The slope (m) is calculated using:
[tex]m = \frac{y_2 - y_1}{x_2 -x_1}[/tex]
This gives
[tex]m = \frac{4 - 2}{2 - 0}[/tex]
Evaluate
m = 1
Hence, the slope of line a is 1
The equation of line aThis is calculated as
y = m(x - x1) + y1
So, we have:
y = (x - 0) + 2
Evaluate the difference and the product
y = x + 2
Hence, the equation of the line a is y = x + 2
See attachment for the graph of line a

- Select all expressions that are equivalent to -96x + 120.
A. 8(-12x+15)
B. -12(8x-10)
C. -8(12x+15)
Answer:
A and B are equivalent to -96x + 120
Step-by-step explanation:
-96x + 120
A. 8 (-12x + 15)
8 * -12x = -96x
8 * 15 = 120
8 (-12x + 15) = -96x + 120
-96x + 120 = -96x + 120
Equivalent
B. -12 (8x - 10)
-12 * 8x = -96x
-12 * -10 = 120
-12 (8x - 10) = -96x + 120
-96x + 120 = -96x + 120
Equivalent
C. -8 (12x + 15)
-8 * 12x = -96x
-8 * 15 = -120
-8 (12x + 15) = -96x-120
-96x + 120 ≠ -96x - 120

omar tariq has a credit card that uses the unpaid balance method to compute the finance charge. His monthly periodic rate is 2.4% during his billing cycle he charged a total of of 256.28 and made payments totaling $350. If he has a finance charge of 18.28, find his (a) unpaid balance (b) previous balance and (c) his new balance
Answer:
(a) unpaid balance = $667.95
(b) Previous balance = $761.67
(c) his new balance = $683.98
Step-by-step explanation:
In the question, we are given the following:
Monthly periodic rate = 2.4%, or 0.024
Curren charges = $256.28
Total payment made = $350
Finance charge = $18.28
Therefore, we now proceed as follows:
(a) unpaid balance
This can be calculated as follows:
Unpaid balance = Previous balance + Current charges - Total payment made ................. (1)
Note that from part (b), Previous balance is equal to $761.67.
Substituting this and other values from the question into equation (1), we have:
Unpaid balance = $761.67 + $256.28 - $350 = $667.95
(b) Previous balance
This can be calculated as follows:
Previous balance = Finance charges / Monthly periodic rate = $18.28 / 2.4% = $18.28 / 0.024 = $761.67
(c) his new balance
This can be calculated as follows:
New balance = Unpaid balance * (1 + Monthly periodic rate) = $667.95 * (1 + 2.4%) = $667.95 * (1 + 0.024) = $667.95 * 1.024 = $683.98
A radio station tower was built in two sections. From a point that is 70 feet from the base of the tower, the angle of elevation to the top of the section is 28 degrees, and the angle of elevation to the top of the second section is 40 degrees. What is the height of the top section of the tower to the nearest tenth of a foot?
Answer:
21.5 feet
Step-by-step explanation:
d = Distance of the bottom of the tower to the point of observation
x = Height of the top section of the tower
a = Height of bottom section
b = Total height of tower
[tex]\tan28^{\circ}=\dfrac{a}{d}\\\Rightarrow a=d\tan28^{\circ}\\\Rightarrow a=70\tan28^{\circ}[/tex]
[tex]\tan40^{\circ}=\dfrac{b}{d}\\\Rightarrow b=d\tan40^{\circ}\\\Rightarrow b=70\tan40^{\circ}[/tex]
[tex]x=b-a\\\Rightarrow x=70\tan40^{\circ}-70\tan28^{\circ}\\\Rightarrow x=70(\tan40^{\circ}-\tan28^{\circ})\\\Rightarrow x=21.5\ \text{feet}[/tex]
The height of the top section of the tower is 21.5 feet.

Sue, Janice and Maria play basketball. This season Sue shot 80 times and made 24 baskets.
Janice shot 35 times and made 16 baskets. Maria shot 145 times and made 59 baskets.
3. What proportion would help you calculate the combined percentage of baskets made for
all players?
Answer:
To start off those are horrible stats, 24 made out of 80, sooo sad :-(
Anyways for your answer you want to look at how many shot attemps
were made by all 3 players
Sue = 80
Janice = 35
Maria = 145
80 + 35 + 145 = 260
260 represent how many shots were taken altogether, which is very important.
From here calculate how many shots were made then divide total shots made with total shots taken.
Hope this helps :)
find the slope of 12x-3y=6
Answer: 4
Step-by-Step Explanation: When written in slope-intercept form, the equation becomes y = 4x - 2; the basic structure of this formula is y=mx+b, where m is the slope and b is the y-intercept.
Knowing this information, we can also figure out the slope and y-intercept. 4, or m, is the slope of the proposed line.

Answer: n-15
Step-by-step explanation: This is because since he is going 15 miles slower than Micale, your write n-15
Answer:
n-15
Step-by-step explanation:
We don't know how fast Micale is traveling, so we use "n". If Joshua is traveling at 15 mph less than Micale, but we don't know how fast Joshua is going, we use n-15.

move the constant to the right hand side change sign
2x = -12 + 6
calculate the sum
2x= -6
Divide the 2 sides by 2

round to the nearest hundredth 4.231
Answer:
4.23
Step-by-step explanation:
When rounding to the nearest hundredth, the number 4.231 becomes 4.231.
To round 4.231 to the nearest hundredth, we look at the digit in the thousandth place, which is 3.
Now, If the digit to the right is less than 5, you simply drop all the digits to the right and keep the desired decimal place unchanged.
If the digit to the right is 5 or greater, you round up the desired decimal place by increasing it by one. Drop all the digits to the right.
Since 3 is less than 5, we do not need to round up.
Therefore, the number remains the same.
Rounded to the nearest hundredth, 4.231 remains as 4.231.

Find the dimensions of the square or circle.
Complete question is;
Find the dimensions or, the square or circle. Area = 64π in²
Answer:
r = 8 inches
Step-by-step explanation:
We know that formula for area of a circle is; A = πr²
Where r is radius.
We are given Area as 64π in²
Thus;
πr² = 64π
π will cancel out to give;
r² = 64
r = √64
r = 8 inches
