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.

Step-by-step explanation:

Answer:

14 yards of string.

Step-by-step explanation:

Since each kite needs 4 2/3 yards of string and there are 3 kites, we have to multiply 4 2/3 by 3.

So, 4 2/3 × 3 = 14.

Answer:

£11.22

Step-by-step explanation:

100% = £13.20

50% = £6.60

10% = £1.32

5% = £0.66

so you would add 10% and 5% together which gives you 15% and 15% is £1.98

and then you could to £13.20 - £1.98 which equals to £11.22  

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.

Answer:

x > - 8

Step-by-step explanation:

Given

48 > - 6x

Divide both sides by - 6, reversing the symbol as a result of dividing by a negative quantity.

- 8 < x , thus

x > - 8

Answer:

x >-8

48>−6x

Step 1: Flip the equation.

−6x<48

Step 2: Divide both sides by -6.

[tex]\frac{-6x}{-6}[/tex]< [tex]\frac{48}{-6}[/tex]

x>−8

Answer:

2 + (3/4)

Step-by-step explanation:

4 + (2/4) - (1 + (3/4))

3 + (2/4) - (3/4)

3 - (1/4)

2 + (3/4)

Answer:

2 and 3/4

Step-by-step explanation:

well start with 4 2/4 and turn it into 18/4 then take 1 3/4 and turn it into 7/4

18/4-7/4=11/4

11/4 is equal to 2 3/4

Answer:

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.

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.

Step-by-step explanation:

Answer:

13.5

Step-by-step explanation:

Answer:

5.38 units

Step-by-step explanation:

Because of the base angle theorem converse, This triangle is an isosceles triangle.

Because this is an isosceles triangle, because the leg of the triangle is 5.38 units, that means the other leg has to be 5.38 units

You may be asking, how do I know it's the other leg that's congruent.

Well, the angle opposite to the 90° angle is the hypotenuse, and we want the line segment opposite of the 45° angle. And both the legs are opposite to the 45° angles.

Answer:

Andrew biked 208 miles.

Andrew biked 208 miles.

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.
