Answer:
y= -3/2X + 2
Step-by-step explanation:
we get the gradient by picking any two points from the graph( it a linear graph)
using the point:
(x,y)= (-2,5) , (4,-4)
using M= (y2-y1)/x2-x1)
we get our gradient to be -9/6 which is
-3/2
using the equation of a straight line graph which is
y-y1=m(x-x1) and the point (4,-4)
we get
y-(-4)=-3/2(x-4)
----> y+4= -3/2x + 6
make y subject of the formula to take the form
y=mx+c
we get :
y=-3/2x + 2

Answers
Answer:
maybe 6 1/2
Step-by-step explanation:
5 square inches is the area of triangle PQR in square inches.
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
Given a triangle PQR.
We need to find the measurement is closest to the area of triangle PQR in square inches.
The PR is 2.6 inches in height and RQ is 4.1 inches.
We know that area of triangle is 1/2 times base and height.
By using ruler we calculated the height of triangle is 2.6 inches and base is 4.1 inches
The formula for area is
Area=1/2(Base×Height)
Plug in the values of base and height
=1/2(4.1×2.6)
=1/2(10.66)
=5.33
=5 square inches
Hence, 5 square inches is the area of triangle PQR in square inches.

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

We simplfiy left and right sideof the eqution.
+1x=+50
We divide both sides of the equation by 1 to get x.

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%

Find the 8th term 50,20,8
Answers
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.

What is the distance between two points(0,0)(-3,5)
Answers
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.
