Find the equation of the linear function represented by the table below in slope-intercept form. x y 1 -9 2 -13 3 -17 4 -21
Answer:
3
Step-by-step explanation:
The linear function or equation in the slope-intercept form will be y = -4x - 5.
What is a linear function?A straight line on the coordinate plane is represented by a linear function.
A linear function always has the same and constant slope.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
The linear function is given as,
y = mx + c
Here, m is the slope while c is the y-intercept.
Slope m = (-13 + 9)/(2 - 1)
m = -4
Put m = -4, (1,-9)
-9 = -4(1) + c
c = -5
y = -4x - 5
Hence "The linear function or equation in the slope-intercept form will be y = -4x - 5".

Answer:
The answer on the right bottom
Step-by-step explanation:
3/4 × 1/2 = 3/8
None of them have 3 shaded but the right bottom
Therefore that'd be your answer
Answer:
bottom right
Step-by-step explanation:
In order to know the answer, you have to find the product of [tex]\frac{3}{4}[/tex] x [tex]\frac{1}{2}[/tex].
Multiply both numerators and denominators in order to get the answer.
[tex]\frac{3}{4}[/tex] x [tex]\frac{1}{2}[/tex] = [tex]\frac{3}{8}[/tex] (this is the lowest term already)
If you check among the choices, it is only the bottom right choice that shows correct shading of the fraction. The diagram divides the right side into 4 equal parts. If you divide the left side into 4 equal parts like this, you'll surely get 8 equal parts of the total diagram. This represents the denominator, 8. The shaded portion represents the numerator, 3.

Write an equation in point-slope form for the line with a slope of 1/4 that passes through the point (-1, -8)
Answer:
y = 1/4 x - 31/4
Step-by-step explanation:
Slope (m) = 1/4
Point A (-1, -8)
y = mx + b
-8 = 1/4 (-1) + b
-8 + 1/4 = b
b = -32/4 + 1/4
b = -31/4
y = mx + b <-- this is a linear equation, continuing line, so there are infinite values for x and y. Therefore we don't have to plug the values of x and y in
y = 1/4 x + - 31/4
y = 1/4 x - 31/4

You plant a spruce tree that grows 4 inches per year and a hemlock tree that grows _____ inches per year. The initial heights are shown. Write a system of linear equations that represents this situation.
Complete Question:
You plant an 8-inch spruce tree that grows 4 inches per year and a 14-inch hemlock tree that grows 6 inches per year.
The initial heights are shown.
Write a system of linear equations that represents this situation.
Answer:
[tex]s(x) = 8 + 4x[/tex]
[tex]h(x) = 14 + 6x[/tex]
Step-by-step explanation:
Given
Spruce Tree (s):
[tex]Initial\ Height = 8[/tex]
[tex]Growth = 4[/tex] (yearly)
Hemlock Tree (h):
[tex]Initial\ Height = 14[/tex]
[tex]Growth = 6[/tex] (yearly)
Required
Represent as system of linear equations
Let the number of years be x.
In both cases, the equation can be formed using:
[tex]Equation = Initial\ Height + Growth * x[/tex]
For Spruce Tree (s):
[tex]s(x) = 8 + 4 * x[/tex]
[tex]s(x) = 8 + 4x[/tex]
For Hemlock Tree (h):
[tex]h(x) = 14 + 6 * x[/tex]
[tex]h(x) = 14 + 6x[/tex]
Hence, the equations are [tex]s(x) = 8 + 4x[/tex] and [tex]h(x) = 14 + 6x[/tex]

Answer:
3- False, 4- TrueStep-by-step explanation:
Garden ARectangle with sides
Width ⇒ 2x - 3 feetLength ⇒ 5(2x - 3) = 10x - 15Perimeter is
2(w + l) = 2( 2x - 3 + 10x - 15) = 24x - 36Garden BTriangle with sides
5x + 5, 4x + 2, 8x - 8Perimeter is
5x + 5 + 4x + 2 + 8x - 8 = 17x - 1Statement 3The difference in perimeters is the difference is fencing:
24x - 36 - (17x - 1) = 24x - 17x - 36 + 1 = 7x - 35Since it is different from 7x - 37 the statement is FALSE
Statement 4Garden A is surrounded by a path of 2.5 ft wide
It will have the perimeter added by 2.5*2*4 = 20 ft as each side is extended by 2*2.5 ft = 5ft
So the perimeter is going to be:
24x - 36 + 20 = 24x - 16This statement is TRUE

Answer:
A function is a relation that is either
one-to-one, meaning each output only has one inputmany-to-one meaning some outputs can have more that one input, but all inputs only have one outputSo, That pic is cramped, don't even know what functions are being referenced but
from the a, b, c, d relation
It is not a function because some inputs have more that one output, which fails our man-to-one ruleFrom the equations
-3x = 15 is not a function, because it only has one input but more than one output breaking rule 12y=10 is a function because every input x has only one output y, it is many-to-one3x-0.25y=3 is a function, it is one to oneFrom the graph
the line is a function, since it is many-to-oneFrom the points
the x coordinate is the input, not points (2,6) and (2,3) have the same input for two outputs, breaking rule 2, that each input should have only one output. So the points are not a functionWhich of the tables represents a function? Table AInput Output 4 3 3 2 3 1 Table BInput Output 1 3 3 5 5 7 Table CInput Output 0 0 1 4 1 5 Table DInput Output 4 1 4 2 4 3 Table A Table B Table C Table D

Elle placed a bucket under a leaky roof. The bucket was 3/10 full after 2/5 of an hour. How much water is leaking per hour?
Answer:
The amount of water leaking per hour is 3/4 of the bucket volume
Step-by-step explanation:
The given parameters are;
The volume of water in the bucket = 3/10 of the bucket volume
The time duration of the leak = 2/5 hour
Therefore;
The leak rate = Volume/Time
The amount of water leaking per hour = (3/10 of the bucket volume)/(2/5 hour)
The leak rate = The amount of water leaking per hour = 3/4 of the bucket volume/hour.
The amount of water leaking per hour is [tex]\frac{3}{4}[/tex] of the bucket volume.
Given ;
The volume of water in the bucket = [tex]\frac{3}{10}[/tex] of the bucket volume
The time duration of the leak = [tex]\frac{2}{5}[/tex] hour
Therefore;
The leak rate = [tex]\frac{volume }{time}[/tex]
The amount of water leaking per hour = ( [tex]\frac{3}{10}[/tex] 0f the bucket volume)/([tex]\frac{2}{5}[/tex] hour)
= ( [tex]\frac{3}{10} . \frac{5}{2}[/tex] ) volume per hour
The leak rate = The amount of water leaking per hour = 3/4 of the bucket volume per hour.

How do you divide mixed fractions
Answer:
See my explanation below.
Step-by-step explanation:
Let's start with two random mixed numbers.
[tex]4\frac{3}{5}[/tex] ÷ [tex]5\frac{1}{4}[/tex]
The first step is starting with [tex]4\frac{3}{5}[/tex]. Think about going from the denominator to the number on the left. After you remember that rule multiply 4 by 5. You should get 20. After that, you add by the numerator. 20 + 3=23
This is how it would be written.
[tex]\frac{23}{5}[/tex]
Do the same for the next mixed number. 5 x 4 = 20 and add by the numerator 21.
[tex]\frac{21}{4}[/tex]
After this is done. You will multiply by those fractions. [tex]\frac{23}{5}[/tex] x [tex]\frac{21}{4}[/tex] = [tex]\frac{483}{20}[/tex] we would write it as [tex]24\frac{3}{20}[/tex] as a mixed fraction.
