Answer:
2 1/4
Step-by-step explanation:
- 5 1/4 - ( - 7 1/2)
Subtracting a negative is like adding
- 5 1/4 + 7 1/2
Get a common denominator of 4
-5 1/4 + 7 2/4
Subtract
7 2/4 - 5 1/4
2 1/4
The right answer is 2 1/4

Let's solve now
[tex] - \frac{8}{13} \times - \frac{26}{3} \\ = \frac{208}{39} \\ = \frac{16}{3} = 5 \frac{1}{3} [/tex]
what is the point slope form of a line with slope -3 that contains the point (2,-2)
Answer:
y+2 = -3(x-2)
Step-by-step explanation:
Point slope form of an equation is
y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line
y - -2 = -3( x-2)
y+2 = -3(x-2)
Answer:
Y=-3x+4
Step-by-step explanation:
Please graphing and all I did was input the coordinates into the Y=mx+b form, got the b and filled in everything else. Hope this helps!

The radius of the cone is 7 in and y = 25 in. What is the volume of the cone in terms of r?
х
O 392nt in
O 408rt in
0 112r in
O 117rt in
Answer:
Hi there!
The correct answer is: 408r in
Step-by-step explanation:
The formula for the volume of the cone is: V = [tex]\frac{1}{3}[/tex]π[tex]r^{2} h[/tex]
where h stands for height, in this case it's y=25
r stands for radius, in this case it's 7 in
when it says leave in terms of "r" it simply means don't multiply the π in
Answer:
392nt in

Jen wants to buy a new house but needs money for the down payment. Her parents agree to lend her money at an annual rate of 4%, charged as simple interest. They lend her $5000 for 6 years. She makes no payments except the one at the end of that time.
Answer the following questions. If necessary, refer to the list of financial formulas.
(a) How much total interest will Jen have to pay?
$
(b) What will the total repayment amount be (including interest)?
$
If they lend her 5000 for 6 years, and the annual interest is 4%, you would get 24% total interest
A) 1200
For B, you add the 5000 to the interest.
B) 6200
Answer:
6200 i think

A line has an c intercept of 3 and a y intercept of negative 6. What is the slope intercept form of it’s equation
y=2x+3
y=2x-6
y=-2x+3
y=-2x-6
Answer:
y = 2x - 6
Step-by-step explanation:
Slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
The y-intercept is already given and is -6.
By c intercept, I am assuming you meant x-intercept. With an x-intercept of 3, the point is (3,0). With a y-intercept of -6, the point is (0,-6).
Use the two points to find the slope using the following equation.
[tex]m=\frac{y_{2}-y_{1} }{x_{2}- x_{1} }[/tex]
Plug the points into their respective positions and solve.
[tex]m=\frac{-6-0}{0-3}\\ m=\frac{-6}{-3} \\m=2[/tex]
The slope is 2.
Your equation is y = 2x - 6.
Brendan ran a total of 8 miles over the course of 4 track practices.
How many track practices would it take for Brendan to run 10 miles? Solve using unit rates.
Answer:
5 track practices
Step-by-step explanation:
So if he ran 8 miles in 4 track practices, he ran 2 miles in each.
So it would take 5 track practices to do it.

Write the standard equation of a circle with center (-9,-4) and radius 15.
(x + 9)2 + (y + 4)2 = 5
(x + 4)2 + (y + 9)2 = 5
(x - 4)2 + (y- 9)2 = 5
(x - 9)2 + (y - 4)2 = 5
Answer:
Equation of a circle:
radius = the sq. rt of (x - h)^2 + (y - k)^2
Plug in the values for the center of a circle and the radius:
15 = the sq. rt of (x + 9)^2 + (y + 4)^2
(x + 9)^2 + (y + 4)^2 = 225

find the value of p in the equation 2p-1 over 5= p-1 over 3
Answer:
p = -2
Step-by-step explanation:
(2p -1)/5 = (p-1)/3
Using cross products
(2p-1) *3 = (p-1)*5
Distribute
6p-3 = 5p -5
Subtract 5p from each side
6p-5p -3 = 5p-5p -5
p -3 = -5
Add 3 to each side
p-3+3 = -5+3
p =-2
Cell phone Company ABC charges a $12 start-up fee plus $0.08 per minute, x/ Cell phone Company WYZ charges $0.20 per minute, x, with no start-up fee. Which function represents the difference in cost between Company ABC and Company WYZ?
Answer:
difference of cost between two company = 12 - 0.12 x
Step-by-step explanation:
For company ABC
start up fee = $12
cost of one minute call = $0.08
if x minute call are done then cost of x call = 0.08*x = 0.08x
total cost incurred in company ABC= startup fee+ cost of x minute call = 12+0.08X
___________________________________________________
For company WYZ
start up fee = 0
cost of one minute call = $0.20
if x minute call are done then cost of x call = 0.20*x = 0.20x
total cost incurred in company WYZ plan = startup fee+ cost of x minute call = 0+0.20x = 0.20x
______________________________________________
difference of cost between two company = 12+0.08x - 0.20x
difference of cost between two company = 12 - 0.12x (Answer)

d. What is the length of the opposite leg on the side of the roof?
e. What measure is the other base angle?
f. What is the measure of the opposite angles?
Answer:
a. 1. Trapezoid
2. Rectangle
b. Trapezoid
c. Isosceles trapezoid
d. 6 feet
e. 65°
f. 115°
Step-by-step explanation:
a. The observed quadrilaterals are;
1. Trapezoid
2. Rectangle
b. Trapezoid
c. Isosceles trapezoid
d. Whereby we have an isosceles trapezoid, the leg lengths are equal. therefore since one of the leg lengths = 6 feet, the other opposite leg on the side of the roof = 6 feet
e. The base angles of an isosceles triangle are equal, therefore, the other base angle is equal to the labelled base angle or 65°
f. The sum of the opposite angles in an isosceles trapezoid = 180°
∴ 65° + Opposite angle = 180°
Opposite angle = 180° - 65° = 115°.
