Answer:

Slope for the first would be 3 and the y intercept is 1. For the second the slope is -4 and the y intercept is 140.

Step-by-step explanation:

For the first one the difference between the first second point is up 6 and over 2 so 6/2= 3 or slope and the y intercept is just where the line intersects the y axis.

For the second question the difference between the points is down 20 units and over 5 so -20/5= slope of -4, and the line intersects the y axis at 140 so that is the y intercept.

If the x value is zero then the y value is the y intercept.

What's the product of 42⁄3 and 111⁄4 ?

svet-max [94.6K]

Answer:

(D) $52\frac{1}{2}$

Step-by-step explanation:

The given fractions are:

$4\frac{2}{3}and 11\frac{1}{4}$ .

We have to find the product of the given fractions, that is:

= $4\frac{2}{3}{\times}11\frac{1}{4}$

Simplifying the mixed fractions, we get

= $\frac{14}{3}{\times}\frac{45}{4}$

= $\frac{105}{2}$

Converting the answer into mixed fraction, we get

= $52\frac{1}{2}$

which is the required answer.

When working with scatterplots and the dots line up on a graph, but more in a curvy line, this would be an example of which mode

Karo-lina-s [1.5K]

The best answer to this question is quadratic. The model that can be seen in a scatterplot wherein the dots line up on a graph in a curvy manner would be the quadratic model.

Additional info: If the dots are forming a straight lne, it's linear. If it shoots up, then it's an exponential one.

Suppose Kaitlin places $ 4000 in an account that pays 18% interest compounded each year.

Ratling [72]

Answer:

a) $4720

b) $5569.60

Step-by-step explanation:

Initial amount = $4000

Interest rate = 18% PA compounded

Amount after 1 year

$4000*1.18 = $4720

Amount after 2 years

$4720*1.18 = $5569.60
