Answer: {(0, 1), (1, 5), (2, 9)}
Step-by-step explanation:
Given linear equation: y-1=4x which can be rewritten as
y=4x+1
To find the set which represents possible inputs and outputs of the function. Let's check all the options
A. {(1, 4), (2, 8), (3, 12)}
at x=1
y=4(1)+1
⇒y=5≠4
Thus this set is not the required set.
B. {(4, 1), (8, 2), (12, 3)}
at x=4
y=4(4)+1
⇒y=16+1=17≠1
Thus this set is not the required set.
C.{(0, 1), (1, 5), (2, 9)}
at x=0
y=4(0)+1
⇒y=1
Thus this set is the required set represents possible inputs and outputs of the function.
D. {(1, 0), (5, 1), (9, 2)}
at x=1
y=5≠0
Thus this set is not the required set.
Use the coordinates J(7, 8), K(1, 2) and L(5, 2) for △JKL.
The centroid for △JKL is at point M. What is JM rounded to the nearest tenth?
prolly D

The distance between the point JM will be 4.81 units.
What is the centroid of the triangle?In science and math, the centroid of a planar figure or firm figure, also known as the point of intersection or center of the figure, is the mean absolute position of all of the other points on the subject's surface.
The centroid of the triangle is given as,
(x, y) = [(x₁ + x₂ + x₃) / 3, (y₁ + y₂ + y₃) / 3]
Use the coordinates J(7, 8), K(1, 2) and L(5, 2) for △JKL. Then the centroid for △JKL is at point M is given as,
(x, y) = [(7 + 1 + 5) / 3, (8 + 2 + 2) / 3]
(x, y) = (13/3, 12/3)
(x, y) = (13/3, 4)
Then the distance between the point JM is calculated as,
D² = (13/3 - 7)² + (4 - 8)²
D² = 7.1111 + 16
D² = 23.11
D = √23.11
D = 4.81 units
The distance between the point JM will be 4.81 units.
More about the centroid of the triangle link is given below.

-6x-2y=42
x-y=-15
Multiply x-y=-15 by 6 ( eliminate the x first)
6(x-y)=6(-15)
(6)(x)=6x
(6)(-y)=-6y
6(-15)=-90
-6x-2y=42
6x-6y=-90
eliminate x the systems of equations by subtracting
-6x+6x-2y+-6y=42-90
-2y-6y=42-90
-8y=-48
divide both sides by -8 to get y by itself
-8y/-8=-48/8
y=6
Find x by substitution method
use y=6 into one of the system of equations
x-y=-15
x-6=-15
move -6 to the other side
sign changes from -6 to +6
x-6+6=-15+6
x=-15+6

Find the gradients of lines A and B. NEED ASAP
Step-by-step explanation:
The line A, the slope is +2
And line B the slope is n-1
Answer:
For A;
x1 = -2, y1 = -3, x2 = 3, y2 = 7
Gradient = (y2 - y1)/(x2 - x1)
= (7 - (-3))/(3 - (-2))
= 10/5 = 2.
For B;
x1 = 7, y1 = -2, x2 = -2, y2 = 7
Gradient = (y2 - y1)/(x2 - x1)
= (7 - (-2))/(-2 - 7)
= 9/-9 = -1.

Find the volume of a pyramid with a square base, where the side length of the base is
14.4 m and the height of the pyramid is 15.3 m. Round your answer to the nearest
tenth of a cubic meter.
Answer:
Volume of pyramid with square base is 1057.54 m³
Step-by-step explanation:
We are given:
Length of base of pyramid = 14.4 m
Height of pyramid = 15.3 m
We need to find:
Volume of pyramid with square base
The formula used is: [tex]Volume=\frac{1}{3}\times a^2 \times h[/tex]
Where a = base of pyramid and h is height
Putting values and finding volume
[tex]Volume=\frac{1}{3}\times a^2 \times h\\Volume=\frac{1}{3}\times (14.4)^2 \times (15.3)\\Volume=\frac{1}{3}\times 207.36 \times 15.3\\Volume=1057.54 \ m^3[/tex]
So, Volume of pyramid with square base is 1057.54 m³

identify the slope and write the equation of the line .
Answer:
y=-2x+5; slope is -2
Step-by-step explanation:
slope is rise/run. we can see it rises 2 and goes left one which would give us rise/run=2/-1=-2. that is our slope.
using y=mx+b to write the equation, m is slope and b is the y-int.. we can see that the y-int. is (0,5). we can plug 5 into b.
plugging b and m in we can get the equation: y=-2x+5

ΔMAT has MA = MT
=> ΔMAT is a isosceles triangle at M
=> ∠A = ∠T = (180° - ∠M)/2
=> x + 20 = (180 - 3x)/2
⇔ 2x + 40 = 180 - 3x
⇔ 5x = 140
⇔ x = 140/5
⇔ x = 28
=> ∠A = ∠T = 28 + 20 = 48°
