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

Answer:
$15.95
Step-by-step explanation:
cost of 1 gram of sweet = $2.10 / 50 = 0.042
Cost of 380 g = 380 x 0.042 = $15.96
to the nearest 5 cent = 15.95

Step-by-step explanation:
Casey polled 50 seventh grade students. He asked who they planned to vote for as class president. Thirty students said they would vote for Lynne. Twenty said they would vote for Marcus.
Use this probability to predict how many seventh graders in their class of 450 students will vote for Lynne
Answer:
270 students
Step-by-step explanation:
First, you need to do a ratio.
30 x
------- = --------
50 450
In order to solve this, you need to multiply 450 times 30 and that equals 13500. 13500 divided by 50 is 270. That means that about 270 students will vote for Lynn.
There is a bag of tiles where 8 are red, 5 are blue, 4 are orange, and 3 are green. If one is picked at random, replaced, and another marble is picked, what is the probability that they are both orange? in a percent or fraction
Answer:
There would be 1/25 chance (4%).
Step-by-step explanation:
So there's 4 orange marbles and there's 20 total marbles since:
8 Red + 5 Blue + 4 Orange + 3 Green
With this, the chance of drawing an orange marble is 4/20, or 1/5. Because the marble is replaced back after being picked, the same chance would occur for the second picking.
To combine these chances, multiply them together for the answer.
1/5 * 1/5 = 1/25 (4%)

Find the 8th term 50,20,8
Answer:
0
Step-by-step explanation:
Answer:
0.08192
Step-by-step explanation:
Given 50, 20, 8, ...
The sequence is geometric in nature
The nth term of the geometric sequence is exoressed as;
Tn = ar^{n-1}
a is the first term = 50
r is the common ratio = 20/50 = 8/20 = 2/5
n is the number of term = 8 (since we need the 8th term)
Substitute
T8 = 50(2/5)^{8-1}
T8 = 50(2/5)^7
T8 = 50(128/78,125)
T8 = 0.08192
Hence the 8th term is 0.08192.

A coordinate plane with a straight line passing through (negative 4, 2), (0, 0), and (4, negative 2).
Which word describes the slope of the line?
positive
negative
zero
undefined
Zeros can be observed graphically or solved for algebraically. A linear function can have none, one, or infinitely many zeros. If the function is a horizontal line ( slope = [latex]0[/latex]), it will have no zeros unless its equation is [latex]y=0[/latex], in which case it will have infinitely many.

Solve for x.
2x + 24
3x - 26
x = [?]
Answer:
set them equal to eachother, i gotta look at my notes tho
Step-by-step explanation:
I think it's like this
3x-26=2x+24
We simpilfy the equation to the form which is simple to understand.
3x-26=2x+24
We move allterms containing X to the left and all others terms to the right
+3x-2x=+24+26
We simplfiy left and right sideof the eqution.
+1x=+50
We divide both sides of the equation by 1 to get x.
x=50

Answer:
The height of the square pyramid is 24 unit.Step-by-step explanation:
Given that:
Edge of the square pyramid = 14 unit Slant height of the square pyramid = 25 unitTo Find:
The height of the square pyramid.We know that:
In pythagoras theorem.
H² = P² + B²Where,
H = Hypotenuse = 25 unitP = Height = Let xB = Base = 14/2 = 7 unitFinding the height of the square pyramid:
⇒ H² = P² + B²
⇒ (25)² = x² + (7)²
⇒ 625 = x² + 49
⇒ x² = 625 - 49
⇒ x² = 576
⇒ x = √576
⇒ x = 24
Hence,
The height of the square pyramid = 24 unitWhat is the rate of change or slope of 2y + 3x = 1
