Hi there! The answer is 50% (or 0.5).

There are 10 students in either the first or the third row. In total we have 20 students. Therefore the probability can be determined by dividing 10 (amount of correct answers) by 20 (total amount of outcomes).

\frac{10}{20}  = 0.5 = 50\%

What is the slope of the line l described by the equation below? y=-2x+4
Masteriza [31]

Answer:

The slope of the line would be -2.

Step-by-step explanation:

Because the equation is a line, the slope is the same throughout the entire graph on the equation.

Lets let f(x)=y=-2x+4.

f(0) = -2(0) + 4 = 4

f(0)=4

f(1) = -2(1) + 4 = 2

f(1)=2

Use the equation to find slope.

m(slope) = \frac{2-4}{1-0} = \frac{-2}{1} = -2

<em>The slope would be -2.</em>

<em />

Or:

Use the equation y = mx + b where m=slope.

In the equation y=-2x+4, m=-2.

<em>The slope is -2.</em>

Can someone give me the answer
Tasya [4]

Take the 4cm side and the 6cm side.

If you hook them together at one end, then there's no way they can reach the ends of the 11cm side.  The farthest they can reach is 10cm.

That's what choice-B says.

John’s teacher gave him the following system of equations and asked him to find the point of intersection. 3x + 2 = y 2x – 3= y
Galina-37 [17]

1) to this case you must match both equations

3x+2 = 2x-3 ⇒3x-2x = -3-2⇒x= -5

now the value of x  substitute it in the any of two equations, y = 3(-5)+2 = -13

and the other equation is the same value

y = 2(-5)-3 = -13

the point is ( -5,-13)
