Below are two different functions, f(x) and g(x). What can be determined about their y-intercepts? graph going through negative

miv72 [106K]

Answer:

The function g(x) has a higher y-intercept.

Step-by-step explanation:

First function f(x):

Slope = (-1, - (-1) / -4 - -1) = 0

So its equation is y = -1.

The y-intercept is (0, -1).

Second function g(x):

Slope = (13-9)/ (6-4) = 2.

y - y1 = m(x - x1) where m = slope and (x1, y1) is a point on the line, so we have:

y - 9 = 2(x - 4)

y = 2x - 8 + 9

y = 2x + 1.

So the y-intercept is (0, 1).

Kiran has a toy car collection. He keeps some in a display case and the rest on the wall. 195 of his toy cars are on the wall, a

morpeh [17]

35% are in display cases which means 65% are on the wall.

this means 195 cars is 65% of the collection.

to get total number of cars in the collection divide 195 by 65%

195/0.65 = 300

For the upcoming holiday season, Dorothy wants to mold 20 bars of chocolate into tiny pyramids. Each bar of chocolate contains 6

abruzzese [7]

Answer:

The largest number of pyramids she can make from 20 bars of chocolate is:

A. 180

Step-by-step explanation:

Firstly, you must find the volume of the 20 bars of chocolate, remember that each bar contains 6 cubic inches of chocolate (6 in^3), so:

Volume of the bars = 6 in^3 * 20
Volume of the bars = 120 in^3

Now, you must find the volume of each pyramid, using the next formula:

Volume of a pyramid = 1/3 B * h

Where:

B = area of the square base.

h = height of the pyramid.

How these values are given in the problem, we only replace the values in the formula:

Area of a pyramid = 1/3 (1 in^2) * 2 in
Area of a pyramid = 2/3 in^3

Finally, we divide the volume of the bars in the volume of each pyramid:

Total number of pyramids = 120 in^3 / 2/3 in^3
Total number of pyramids = 180

xz_007 [3.2K]

Answer:

The range of given data set is 90.

Step-by-step explanation:

We are given the following data:

20.9, 33.1, 21.8, 58.5, 23.5, 110.9, 30.4, 24.9, 74.1, 60.3, 40.4, 45.4

When this data is arranged in ascending order, we get:

20.9 , 21.8 , 23.5 , 24.9 , 30.4 , 33.1 , 40.4 , 45.4 , 58.5 , 60.3 , 74.1 , 110.9

Range is a measure of dispersion and can be easily calculated.

Formula:

$Range = \text{Maximum values - minimum value}$

$Range = 110.9 - 20.9 = 90$

Thus, the range of given data set is 90.

What is the value of x

mihalych1998 [28]

Answer:

Step-by-step explanation:

x+15+x+115+90=380 degree(sum of interior angles of four angles is 360 degree)

2x+220=360

2x=360-220

x=140/2

x=70 degree
