Ming wrote the table of points below.
x
y
5
10
10
20
15
30
Which explains whether or not Ming has described a proportional relationship, and why?
Ming has described a proportional relationship because the ordered pairs are linear and the line passes through the origin.
Ming has not described a proportional relationship. Although it is a linear relationship, it does not pass through the origin.
Ming has not described a proportional relationship. Although it passes through the origin, it is not a linear relationship.
Ming has described a proportional relationship because the line does not pass through the origin.

Solve by using substitution -5x-y=12 y=-4x-9
Answer:
(-3, 3)
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesAlgebra I
Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define systems
-5x - y = 12
y = -4x - 9
Step 2: Solve for x
Substitution
Substitute in y: -5x - (-4x - 9) = 12Distribute negative: -5x + 4x + 9 = 12Combine like terms: -x + 9 = 12Subtract 9 on both sides: -x = 3Divide -1 on both sides: x = -3Step 3: Solve for y
Define original equation: y = -4x - 9Substitute in x: y = -4(-3) - 9Multiply: y = 12 - 9Subtract: y = 3simplify the expression. -1/4 -(1 1/2)

The second one y<2x-6
Step-by-step explanation:
Based on the shading we can tell that the sign is going to always be shaded on the right side. We see the line is dashed (its kinda hard to see) but a dashed line means none of the points on it can be part of the solution. If it was a solid line it would be ≤ and we see it's not so its <

HELP PLEASE I DONT UNDERSTAND AND NEED TO PASS
Answer:
1: 80 degrees
Step-by-step explanation:
1:
Angle R is 130
Angle S is 60
Quadrilatural's angles add up to 360
360 - 130 - 60 = 170
In my opinion angle U looks like a right angle so 90 degrees.
170 - 90 = 80
so 80 degrees

Factor completely x3 – 3x2 - 9x + 27
Answer:
x³ - 3x² - 9x + 27
= x²(x - 3) - 9(x - 3)
= (x² - 9)(x - 3)
= (x -3)(x + 3)(x - 3)
= (x + 3)(x - 3)²

Answer:y= (3/4)x -7/4
Step-by-step explanation:
[y -(-1)]/[x - 1] = [2 -(-1)]/[5 - 1]
[y + 1]/[x - 1] = 3/4
y + 1 = (3/4)x - 3/4
y = (3/4)x - 7/4.
Jaylen has a pet grooming business. In 2018, he groomed 200 dogs. In 2019, he groomed 450 dogs. What was the percent increase in the number of dogs groomed? Don't forget your % sign.
Answer:
Percentage increase= 125%
Step-by-step explanation:
Giving the following information:
2018= 200 dogs
2019= 450 dogs
To calculate the percentage increase, we need to use the following formula:
Percentage increase= [(2019 - 2018)/2018]*100
Percentage increase= [(450 - 200)/200]*100
Percentage increase= 125%

Write a power that has a value greater than 140 and less than 145.
Answer:
[tex]12^{2}[/tex]
Step-by-step explanation:
To find: a power that has a value greater than 140 and less than 145
Solution:
Take [tex]x=12^{2}[/tex]
Here,
[tex]12^{2}=144[/tex] and [tex]140<144<145[/tex]
That is [tex]140<x<145[/tex]
Therefore,
[tex]12^{2}[/tex] has a value greater than 140 and less than 145.

Lincoln High School's basketball team won the regional playoffs scoring a
total of 60 points, not including free throws. The team made a total of 26
baskets; some were 2-point shots, and the rest were 3-point shots. How
many 2-point shots did the team make?
Answer:
y = 8
x = 18
Step-by-step explanation:
(x + y = 26) x2 -1
2x+3y = 60 -2
2x+2y = 52 -1
2x+3y = 60 -2
Subtracting equation 2 from equation 1
= -y = -8
= y = 8
_____________________________________________________
2x+3y = 60
= 2x+3x8 = 60
= 2x+24 = 60
= 2x = 60-24
= 2x = 36
= x = 36/2
= x = 18
What is the length of DF? Round to the nearest hundredth.
Answer:
7.06
Step-by-step explanation:
This triangle can be solved a couple of ways. In the end, they amount to the same thing.
1) The area is ...
A = 1/2bh = 1/2(8)(15) = 60 . . . using DG as the base
Using GE as the base, the height (DF) is ...
A = (1/2)(17)(DF)
2(60)/17 = DF = 120/17
DF ≈ 7.06
__
2) Using similar triangles, we can find the ratio of the long side to the hypotenuse as ...
(long side)/(hypotenuse) = DE/GE = DF/DG
DF = DG(DE/GE) = 8(15/17) = 120/17
DF ≈ 7.06

Write 0.25x+1y=12 in slope-intercept form.
Answer:
y = -.25x + 12
Step-by-step explanation:
Subtract x on both sides.
y = -.25x + 12
There is your answer. The "1" before the y doesn't need to be written, as a rule in algebra, ones do need to be written and are assumed to be there if there is no number at all.
-.25 is the slope and 12 is the y-intercept.
11. A large pine tree was struck by lightning and fell as
shown by the diagram below. Which equation
could be used to find the length of the fallen part of
the tree?
8 ft
13 ft —
A. 82 +132 - X
B. N82+132 -
C. 132 - 82 = X
D. V132 - 82 - *
It forms a right triangle.
To find X you can use the Pythagorean theorem which would be written as x^2 = a^2 + b^2
This can be rewritten as x = sqrt(a^2 + b^2)
Using the dimensions of the tree the answer would be :
B. x = sqrt(8^2 + 13^2)
The equation to find the length of the fallen part of the tree is
[tex]x=\sqrt{8^2+13^2}[/tex]
Right Triangle.
Right triangles is a triangle with one angle is 90 degree.
The side opposite to 90 degree is the hypotenuse.
Pythagorean Theoremthe sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse .
The length of the fallen part of the tree is the hypotenuse
Hypotenuse is 'x'
Base of the triangle is 13 feet and height is 8 ft
Apply Pythagorean theorem to find out the hypotenuse 'x'
[tex]hypotenuse^2= base^2 + height ^2\\x^2=\sqrt{13^2+8^2} \\x=\sqrt{13^2+8^2}[/tex]
the equation to find the length of the fallen part is
[tex]x=\sqrt{8^2+13^2}[/tex]

3x+2y=5
2x+2y=4
Answer:
(x,y)=(1,1)
Step-by-step explanation:
got it right on a test
Answer:
X=+4
y=-2
Step-by-step explanation:
this is simultaneous equations
hence,
using elimination method
3x+2y=5
2x+2y=4
2y eliminates 2y
3x+2x=5x=5*4
5x=20
X=20/5
X=+4
(2)
to find "y"
take any of the equation above
using equ(2)
2x+2y=4
2(4)+2y=4
+2y=+4-8
+2y=-4
y=-4/2
y=-2

Blank = 2/7
Step-by-step explanation:
how many squares would have to be shaded to that 1/6 of the shape is shaded
Answer:
3 squares
Step-by-step explanation:
Firstly, you have to count the number of squares in the shape. As it can been seen from the diagram, there are a total 18 squares (i.e 6 squares on each row × 3 squares on each column).
Secondly you have to find 1/6 of the total number of the squares in the shape. 1/6 of the total number of the square in the shape = 1/6 × 18 = 3 squares
Therefore 3 squares would have to be shaded so that 1/6 of the shape is shaded
