i need help with this slope problem
Answer:
It is the first one and the second one. If it is the same, then the slope will be constant.
Step-by-step explanation:
Answer:
I think it's the second one ( Any two points on the line will produce the same slope)
Step-by-step explanation:
Any two points on a line will ALWAYS have the same slope. There's no way that it won't be that way. That's why you are able to choose any two points on a graph to find a slope.
For the first one, i think it's wrong because although the slope is 1/2, Jennifer used the slope 2/4 while Marshall used 1/2. Even though it's the same, Jennifer didn't technically use 1/2...
And the third option is wrong. The slope isn't 2.
Hopefully this wasn't confusing... :)

Jordan throws a ball from a cliff 12 feet above the ground with an initial velocity of 32 feet per second. In the following functions, h(t) represents the height of the ball above the ground, in feet, with respect to time, t, in seconds, after the ball was thrown. Which of the following functions models the amount of time the ball is in the air?
h(t)= -4(t-1)^2 +3
h(t)= -16(t-1)^2 -4
h(t)= -16(t-1)^2 +12
h(t)= -16(t-1)^2 +28
Answer:
Your answer will be the third function
Step-by-step explanation:
The base function you need to know is h(t)= 1/2at^2
Your acceleration in this problem is going to be gravity which they give to you, 32 feet per second squared. Since the ball is falling, it means it will have negative acceleration. Now you have the equation h(t)= -16t^2. The final step is to add the initial height from which the ball was dropped giving you: h(t)= -16t^2 +12
A shopper bought 6 shirts and 8 hats for $700. A week later, at the same prices, he bought 9 shirts and 6 hats for $660. What was the cost of one shirt?
Answer:
Cost of one shirt = $ 30
Step-by-step explanation:
Let cost of 1 shirt = s
Cost of 1 hat = h
A shopper bought 6 shirts and 8 hats for $700.
6s + 8h = 700 -------------------(I)
A shopper bought 9 shirts and 6 hats for $660
9s + 6h = 660 -----------------(II)
Multiply equation (I) with 9 and multiply equation (II) with (-6) and then add. SO, now 's' will be eliminated and we can find the value of 'h'
(I) * 9 54s + 72h = 6300
(II)*(-6) -54s - 36h = - 3960 {Now add}
36h = 2340
h = 2340/36
h = 65
Cost of one hat = $ 65
Substitute h = 65 in equation (I)
6s + 8 * 65 = 700
6s + 520 = 700
6s = 700 - 520
6s = 180
s = 180/6
s = 30
Cost of one shirt = $ 30
Answer: One shirt is $30

Caroline's family took a road trip to the Grand Canyon. Caroline fell asleep 58% of the way through the trip. If Caroline fell asleep after they had travelled 348 miles, what was the total length of the trip?
Answer:600 miles
Step-by-step explanation:
Hello!
So you know that 348 miles is equal to 58% so you want to figure out what 1% of the total trip is
348 / 58 = 6
You know that 1% of the trip is 6 miles so now to figure out what the total trip is you multiply 6 by 100
6 * 100 = 600
So you know that the total length of the trip is 600 miles long.
Is a repeating decimal a rational number
A. Yes because it can be written as a/b and a and b are integers and b =0
B. Yes because it can be written in the form a•b where a and b are integers
Answer:
Option A
Step-by-step explanation:
The answer to this question is option A or "Yes because it can be written as a/b and a and b are integers and b =0." Any number that can be written as a fraction is a rational number. In this case repeating decimals can be written as a fraction using different types of algebraic methods making it a rational number.

x=
Answer:
[tex]x=3.5[/tex]
Step-by-step explanation:
Notice that CD bisects Angle C.
Then by the Angle Bisector Theorem, we can write the following proportion:
[tex]\frac{6}{4.2}=\frac{5}{x}[/tex]
Now, we can solve for x. Cross multiply:
[tex]5(4.2)=6(x)[/tex]
Multiply:
[tex]21=6x[/tex]
Divide both sides by 6:
[tex]x=21/6=7/2=3.5[/tex]
Hence, the vale of x is 3.5.

A rectangular carpet measures 12 m by 5 m.
Part of the carpet is covered by a square rug of length 2 m.
What fraction of the carpet is covered by the rug? Give your answer in its simplest form.
I'm pretty sure the answer is 1/15 or 4/60 because the whole carpet measures 60m and the covered part's area is 4m and that would be 4/60 but simplified 1/15. Sorry if this is wrong!
To find the fraction of the carpet covered by the rug, we need to determine the area of the rug and divide it by the total area of the carpet.
The area of the square rug can be calculated by squaring its side length: 2m x 2m = 4m². The total area of the rectangular carpet can be found by multiplying its length and width: [tex]12m x 5m = 60m²[/tex]. To find the fraction, divide the area of the rug by the area of the carpet: 4m² / 60m².
To simplify the fraction, we can find the greatest common divisor (GCD) of 4 and 60, which is 4. Dividing both the numerator and denominator by the GCD, we get: [tex]4m² ÷ 4 / 60m² ÷ 4 = 1m² / 15m²[/tex] . Therefore, the fraction of the carpet covered by the rug is 1/15, which means that 1/15th of the carpet is covered by the rug.

What would the exponential equation be ?
Answer:
The equation of the exponential function will be:
[tex]f\:\left(x\right)\:=\:ab^x[/tex]
[tex]=\:\frac{3}{2}\left(2\right)^x[/tex]
Step-by-step explanation:
Given the table
Day Bacteria
1 3
2 6
3 12
4 24
5 48
as
the x values have the same increment i.e. +1and
the y values have common ratio i.e. 6/3 = 2, 12/6=2, 24/12=2so it is indeed an exponential function
As we know that the exponential function is of the form
[tex]f\:\left(x\right)\:=\:ab^x[/tex]
As we know that the y-intercept of [tex]f\:\left(x\right)\:=\:ab^x[/tex] is (0, a).
so
[tex]\frac{3}{a}=2[/tex] ∵ common ratio = successor y-value ÷ previos y-value
[tex]a=\frac{3}{2}[/tex]
so the value of a will be: 3/2
We also know that the common factor i.e. multiplier is 2 in this table, we know the value for b is 2.
Therefore, the equation of the exponential function will be:
[tex]f\:\left(x\right)\:=\:ab^x[/tex]
[tex]=\:\frac{3}{2}\left(2\right)^x[/tex]

The slope of the line is 3
The difference between the consecutive term of the sequence is (1, 3)
To get the slope of the graph, we will use the coordinate points (2, 10) and (3, 13)
Slope = 13-10/3-2
Slope = 3/1
Slope = 3
Hence the slope of the line is 3
The difference in the term for the x-coordinate is given as:
x = 3 - 2 = 4 - 3 = 5 -4 = 1The difference in the term for the y-coordinate is given as:
x = 13 - 10 = 16 - 13 = 19 -16 = 3Hence the difference between the consecutive term of the sequence is (1, 3)

c-y+3=-4(x+6)
d-Y-6=-4(x+3)
Answer:
1+1=magelan
2plus2 lapulapu
Answer:
b and d
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
m is the slope and (a, b) a point on the line
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 3, 6) and (x₂, y₂ ) = (- 2, 2) ← 2 points on the line
m = [tex]\frac{2-6}{-2+3}[/tex] = - 4
Using (a, b ) = (- 3, 6 ), then
y - 6 = - 4(x - (- 3)), that is
y - 6 = - 4(x + 3) → d
Using (a, b ) = (- 2, 2 ), then
y - 2 = - 4(x - (- 2)) , that is
y - 2 = - 4(x + 2) →b
