Answer:

2 1/2 inches

Step-by-step explanation:

Here, we want to give the measurement of point A that is marked on the ruler

We have this as;

As we can see, we have the whole number of inches before it as 2

Now, the small intervals between each of the whole numbers on the ruler is;

1/8

A is at the 4th point

So we have its measure added to 2 as:

2 + (4 * 1/8)

= 2 1/2 inches

The system of equations above is graphed below. Find the solution to the system.

Option D: $x=3,y=-2$ is the solution to the system of equations.

Explanation:

Given that the equations are $4x+y=10$ and $2x+y=4$

We need to determine the solution of the system of equations.

The solution can be determined by solving the two equations.

Let us solve the system of equations using substitution method.

Consider the equation $4x+y=10$ , the value of y is given by

$y=10-4x$

Substituting the value of $y=10-4x$ in the equation $2x+y=4$ , we get,

$2x+(10-4x)=4$

Simplifying, we get,

$2x+10-4x=4$

$-2x+10=4$

$-2x=-6$

$x=3$

Substituting the value of $x=3$ in $4x+y=10$ , we get,

$4(3)+y=10$

$12+y=10$

$y=-2$

Thus, the solution to the system of equations is $x=3,y=-2$

Hence, Option D is the correct answer.

What is the equation of the line that is parallel to the line y = x + 4 and passes through the point (6, 5)?

Tanzania [10]

The line y=x+4 is given in slope-intercept form (y=mx+b) where m is slope and b is the y-intercept.

Parallel lines have the same slope, so we know the line will have a slope of 1. To find the equation of the new line we can plug the slope and given point into the point-slope equation defined as y-k = m(x-h) given point (h,k).

y-5 = 1(x-6)

Now solve the equation for y.

The answer is: y = x - 1

None of the choices are correct.

Dennis_Churaev [7]

Answer:

1/25

Step-by-step explanation:

The bag has:

2 yellow marbles
3 red marbles
5 blue marbles
10 total marbles

The probability of picking a yellow marble is 2/10=1/5.

So, the answer is (1/5)² = 1/25
