Step-by-step explanation:
Which equation represents the linear relationship between x and y that is shown in the
table below?
Answer:
y= 5-x
Step-by-step explanation:
We notice that when we put 5 for x we get 0 which means that we must be subtracting the given x value by constant
y= 5-x makes sense, try plugging in any x value given in table and you will get its y counterpart back.
For eg, when x= -1
y= 5- (-1) = 6 (negatives add)

What is the distance between two points(0,0)(-3,5)
Step-by-step explanation:
Think of it like a right triangle. Do you have a graph handy?
Ok, graph both of the points. Now connect the points. That's our hypotenuse and the side length we want to find.
Now, bring down a line from (-3,5) to the x axis. Do you see a right triangle?
All we have to do is find the hypotenuse of this right triangle we just drew. We already have the leg lengths which are 3 and 5. Using this, do the pythagorean theorem.
9+25=34
√34 is our hypotenuse & distance between the points

2n^2+3n=-54
a) {4,-9}
b) {6,-2}
c) {9,-3}
d) {-4 1/2, 6}
Answer:
Step-by-step explanation:
Rewrite this quadratic equation in standard form: 2n^2 + 3n + 54 = 0. Identify the coefficients of the n terms: they are 2, 3, 54.
Find the discriminant b^2 - 4ac: It is 3^2 - 4(2)(54), or -423. The negative sign tells us that this quadratic has two unequal, complex roots, which are:
-(3) ± i√423 -3 ± i√423
n = ------------------- = ------------------

4) A zoologist was checking the weights of three gorillas. Gorilla A weighed 559 pounds, gorilla B weighed 827 pounds and gorilla C weighed 130 pounds. What is the combined weight of all three gorillas?
Answer:
1,516 pounds
Step-by-step explanation:
Gorilla A weighed = 559 pounds Gorilla B weighed = 827 pounds Gorilla C weighed = 130 pounds
Total weight of the gorillas = gorilla A + gorilla B + gorilla C
= 559 pounds + 827 pounds + 130 pounds
= 1,516 pounds
Total weight of the gorillas = 1,516 pounds

Plot c so its distance from the origin is 1. Plot poin e 4/5 closer to the origin than c. What is its cooridinate?
Answer:
[tex]C = (1,0)[/tex]
[tex]E = (0.8,0)[/tex]
See attachment for C and E
Step-by-step explanation:
Given
[tex]O= (0,0)[/tex] --- Origin
[tex]CO = 1[/tex] --- distance of C to O
Solving (a): Plot point C
Calculate the coordinates of C using distance formula:
[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 -y_1)^2}[/tex]
Where:
[tex]O= (0,0)[/tex] ---[tex](x_1,y_1)[/tex]
[tex]C = (x,y)[/tex] -- [tex](x_2,y_2)[/tex]
[tex]d = CO = 1[/tex]
So, we have:
[tex]1 = \sqrt{(x - 0)^2 + (y -0)^2}[/tex]
[tex]1 = \sqrt{x^2 + y^2}[/tex]
Square both sides
[tex]1^2 = x^2 + y^2[/tex]
[tex]x^2 + y^2 =1[/tex]
For this solution, we assume y = 0
[tex]x^2 + 0^2 =1[/tex]
[tex]x^2=1[/tex]
Solve for x
[tex]x = 1[/tex]
So, the coordinates of C is: (1,0)
[tex]C = (1,0)[/tex]
Solving (b): Plot point E
We have that E is 4/5 closer to the origin.
This implies that, the ratio is:
[tex]m : n = 4/5:1/5[/tex]
Multiply by 5
[tex]m : n = 4:1[/tex]
So, E is at 4:1 between O and C
Calculate the coordinates of E using:
[tex]E = (\frac{mx_2 + nx_1}{m + n},\frac{my_2 + ny_1}{m + n})[/tex]
Where
[tex]O= (0,0)[/tex] ---[tex](x_1,y_1)[/tex]
[tex]C = (1,0)[/tex] --- [tex](x_2,y_2)[/tex]
[tex]m : n = 4:1[/tex]
[tex]E = (\frac{4*1 + 1 * 0}{4 + 1},\frac{4*0 + 1*0}{4 + 1})[/tex]
[tex]E = (\frac{4}{5},\frac{0}{5})[/tex]
[tex]E = (0.8,0)[/tex]

Compare and contrast the Division Property of Equality and the Division Property of Inequality
O A The two properties are exactly the same.
B. The two properties are exactly the same when dividing by a positive number. For the Division Property of Inequality, dividing by a negative
number causes the relation symbol to change. Dividing both sides of an equation by a negative number does not have an effect on the equal
sign
OC. The two properties are exactly the same when dividing by a negative number. For the Division Property of Inequality dividing by a positive
number causes the relation symbol to change. Dividing both sides of an equation by a positive number does not have an effect on the equal
sign
D. The two properties are exactly the same when dividing by a positive number for the Division Property of Equality, dividing by a negative

Thenks and mark me brainliest :))
Answer:
The probability that the third student will draw a green is 19%.
Step-by-step explanation:
Definition of Probability Probability means possibility of occurrence. It is a branch of mathematics which deals with the occurrence of particular event out of some random events.Given marbles 10 red, 10 blue, 8 green, 8 purple, and 8 yellow marbles .
Therefore total marbles will be 44.
Since the first student in the room draws a yellow, and the second draws a blue ,thus remaining marbles will be 42.
So, the probability that the third student will draw a green is [tex]\frac{8}{42}[/tex]×[tex]100\\[/tex] = 19%
