The y-intercept is (26, 0)

Step-by-step explanation:

The Y intercept is the point at which the line crosses the  y-axis, or when x is equal to zero. Here when x = 0, y = 26. So the y-intercept is (26, 0). They want to trick you into choosing the slope is -1/6, but that is wrong because id you look at the x-axis it is not going by 1's.

What is Multiplication?

Multiplication in mathematics is the method of finding the product of two numbers. It is usually denoted by a × b.

For two numbers a and b, a × b is defined as either 'a' is added repeatedly upto 'b' times or 'b' is added repeatedly upto 'a' times.

Given that,

Number of miles Emily biked = 13 miles

Number of miles Isaiah biked = 4 times as many miles as Emily

                                                 = 4 × 13

                                                 = 52 miles

Number of miles Andrew biked = 4 times as many miles as Isaiah

                                                     = 4 × 52

                                                     = 208 miles

Hence, Andrew biked the farthest which is equal to 208 miles.

explain what the Diameter is and how is the radius related to it.

What can the radius and Diameter help us find?

Answers

Answer:

The diameter is any straight line that passes through the center of the circle, which endpoints can lie on. The radius is half the diameter. They help us find the circumference of a circle

Answer:

The diameter is the length of the line through the center that touches two points on the edge of the circle. It is related to the radius because whatever the diameter is is double what the radius is.  In differential geometry, the diameter is an important global Riemannian invariant.

Write the slope intercept form of the equation of each line

Answers

Answer:

The slope is 1/4 so the slope intercept form is y=1/4+3

Step-by-step explanation:

To find the slope the easiest way from looking at a graph is just to find the rise over run. From looking at the graph we can see that the next point from 0,3 is 4,4. The y here is increased by 1, which means the rise is 1. The x is increased by 4 so the run is 4. From putting rise (1) over run (4) the slope is 1/4. The formula for slope intercept is y=mx+b. m is slope so we substitue that for 1/4 so now we have y=1/4x+b. Then the b is the y intercept, or, at what point the line crosses the y line. Which in this case is 0,3 so the y intercept would be 3 because that is what height it crosses the y line.

Answers

Answer:

4

Step-by-step explanation:

You need to try out all the numbers.

lets start with 4

if there where 4 red marbles then there would be 9 times as many marbles

so 4 x 9 = 36

Now we add and see if the sum is 40

36 + 4 = 40

We got it on the first try

You can use the same method on more problems like these.
