1A, 2B, 3C
Step-by-step explanation:
The bars in the middle are the medium 50%. The line in the middle is the medium. The line on the outside is the range.
Divide 654 by 218
The number is 3
ANSWER and EXPLANATION
We want to plot the line represented by the equation:
where slope = 1/3
y intercept = 2
The quickest way to plot this graph is to get at least two coordinate points from the equation and then join them.
The first coordinate point we can use is the y intercept.
The y intercept is the value of y when x is 0. This means that the coordinate point of the y intercept is (0, 2)
Now, that we have one point, we can get another by using the slope.
Slope is defined as the vertical rise divided by the horizontal run, which means that from any point on the graph, if we add the rise to the y coordinate and the run to the x coordinate, we will get another point on the graph.
The slope is:
So: rise = 1; run = 3
Therefore, adding that to the y intercept, we have:
(0 + 3, 2 + 1) => (3, 3)
Now, we have two points (0, 2) and (3, 3)
Let us plot the graph:
That is the graph of the line.
Answer:
( 2x +3 ) (x-4 )
Step-by-step explanation:
2x²-5x-12
Factor
( 2x ) (x )
We need to look at the factors of -12
-1 *12 -2 *6 -3*4 -4*3 -6*2 -12*1
What multiplies 2 * 1st factor + the other factor to equal -5
2* -4 +3 = -8+3 =5
so the -4 goes on the outside and the 3 goes on the inside
( 2x +3 ) (x-4 )
Answer:
D. y = 2x + 3
Step-by-step explanation:
Use the table to answer the question.
x:-2 -1 0 1 2
y: -1 1 3 5 7
Which equation represents the relationship between x and y shown in the table.
Solution:
The table shows a linear relationship between x and y.
A linear equation is in the form y = mx + b, where y is a dependent variable, x is an independent variable, m is the rate of change (slope) and b is the value of y when x = 0.
The table (x, y) has the points (-2, -1) and (0, 3). The equation is given by:
