write an equation of the line in a slope intercept form of a line that passes through (5,7) and (4,4)
Answer:
y = 3x - 8
Step-by-step explanation:
passes through (5, 7) and (4, 4)
Find slope:
(7 - 4) / (5 - 4)
= 3/1
= 3
This is your slope.
Now plug in a set of coordinates.
y = 3x + b
7 = 3(5) + b
7 = 15 + b
b = -8
Your equation is: y = 3x - 8
Check your work by plugging in the second coordinate pair.
y = 3x - 8
4 = 3(4) - 8
4 = 12 - 8
4 = 4
Your solution is correct.

Answer:
30
Step-by-step explanation:
Just answer the question if you actually answer it you get brainliest and 50 points.
Step-by-step explanation:
f(x) = a * b^x
We have the following information:
f(0) = a * b^(0) = 15. => a * 1 = 15, a = 15.
f(1) = a * b^(1) = 9. => a * b = 9, (15) * b = 9, b = 0.6.
Hence f(x) = 15 * 0.6^x.
Does the system have no solution?
Answer:
[tex]\mathrm{A)\:}-6[/tex]
Step-by-step explanation:
Notice that in the second equation, the coefficient of [tex]y[/tex] is [tex]2[/tex] times greater than in the first. Therefore, by making the coefficient of [tex]x[/tex] in the second equation [tex]2[/tex] times greater than in the first, it's impossible to only isolate one variable.
Therefore, when [tex]a=-3\cdot 2=\fbox{-6}[/tex], there are no solutions to this system.

Answer:
About 527.79
Step-by-step explanation:
formula is A=2πrh+2πr^2
Answer:
[tex]527.52\:\mathrm{in^2}[/tex]
Step-by-step explanation:
The surface area of this cylinder consist of two circles and a 3D outer edge with respect to the circumference. The area of a circle is given as [tex]r^2\pi[/tex]. Using [tex]\pi=3.14[/tex] as requested in the problem, the area of both these circles is:
[tex]2\cdot6^2\cdot 3.14=226.08\:\mathrm{in^2}[/tex].
The area of the outer edge is the circumference of the circle multiplied by the height. The circumference of a circle is given by [tex]2r\pi[/tex].
Therefore, the circumference's 3D outer edge is:
[tex]8\cdot2\cdot6\cdot 3.14 = 301.44\:\mathrm{in^2}[/tex].
Adding these up, the total surface area is:
[tex]226.08+301.44=\fbox{$527.52\:\mathrm{in^2}$}[/tex].

Composition of functions~
Answer:
option D
Step-by-step explanation:
First you must find g(n) given that n is -3n:
g(-3n) = -3n - 1
Then plug that in f(n) as the new n:
f(n) 3( -3n - 1) + 5
= -9n -3 + 5
= -9n + 2
So option D

Answer:
The value of x = 12.
Step-by-step explanation:
We know that two angles are termed as supplementary when the sum of the measure of their angles is 180°.
We also know that a straight line angle measures 180°.
It is clear that the angles 72° and 9x° line on a straight line. Thus, the sum of the measure of their angles is 180°.
Therefore,
9x° + 72° = 180°
9x° = 180° - 72°
9x° = 108
divide both sides by 9
9x/9 = 108/9
x = 12
Therefore, the value of x = 12.
Tyler says he invented a number puzzle.
He asks Clare to pick a number, and then asks her to do the following:
Triple the number
Subtract 7
Double the result
Subtract 22
Divide by 6
Clare says her final answer is -3. Tyler says her original number she thought must have been 3.
How did Tyler know that? Explain or show your reasoning.
A rectangular prism measures 7 & 1/2 cm by 12 cm by 15 & 1/2 cm. Calculate the number of cubes with edge length 1/2 cm that fit in this prism.
Answer: 8 cubes
Step-by-step explanation:
Volume of a rectangular prism is length × height × width
Length=7 1/2
Width= 15 1/2
Height=12
Volume of the prism is therefore:
7 1/2×12×15 1/2= 1395cm3
No of cubes with edge length 1/2 to fit into the prism will be:
Volume of cube is L*W*H
1/2*1/2*1/2= 1/8cm3
Therefore the no of cubes to fit into the Prism will be:
1395/(1/8)= 11160 cubes.
If one was stuck,the number of 1/2 edge length
cube to fit into 1cm will be:
1/(1/8)= 8 cubes
Domingo is replacing the baseboards in his home and calculates that he will need 637.5 feet of wood. When he travels to the hardware store, he discovers that baseboards are sold in 7.5-foot lengths. How many boards will Domingo need to purchase?
Answer:
Number of boards= 85
Step-by-step explanation:
Giving the following information:
Total wood required= 637.5 feet of wood
The baseboards are sold in 7.5-foot lengths.
To calculate the number of boards, we need to use the following formula:
Number of boards= total wood required / foot per board
Number of boards= 637.5 / 7.5
Number of boards= 85

Meryl needs to cut down 10.5 trees for every 5 cabins she builds.
Complete the table using equivalent ratios.
Number of trees Number of cabins
10.5 5
__ 3
__ 7
Answer:
for seven cabins it should be 14.7 trees, im not sure about 3 cabins, sorry :(
Answer:
3) 6.3
7) 14.7
Step-by-step explanation:
Use ratios to solve the table
10.5/5 = x/3
cross multiply
31.5 = 5x
x = 6.3
10.5/5 = x/7
73.5 = 5x
x = 14.7

Answer:
p = 6
Step-by-step explanation:
The slope equation is:
[tex]m = \frac{y \frac{}{2} - y \frac{}{1} }{x \frac{}{2} - x \frac{}{1} } [/tex]
then to know the value of "p":
[tex] - \frac{1}{3} = \frac{7 - p}{p - 9} \\ - 1(p - 9) = 3(7 - p) \\ - p + 9 = 21 - 3p \\ 3p - p = 21 - 9 \\ 2p = 12 \\ p = \frac{12}{2} \\ p = 6[/tex]
