3.) Find the value of y that makes the equation y= x + 1/4 true, when x = - 1/4.

A.) -4
B.) 0
C.) 1
D.) 4​

Answers

Answer:

1) B

2) D

3) B

Step-by-step explanation:

For question 1:

Assuming that option B is [tex]x^3=1[/tex], it is not a linear function.

Linear functions have equations that do not have exponents.

For question 2:

[tex]y=-(-4)+5\\\\y=4+5\\\\\boxed{y=9}[/tex]

The option is D.

For question 3:

[tex]y=x+\frac{1}{4}\\\\ y=-\frac{1}{4}+\frac{1}{4}\\\\ \boxed{y=0}[/tex]

The option is B.

Hope this helps.

What is the slope of the line passing through the points (-3, 4) and (2, – 1)?

Answers

Answer:

m=-1 or -1/1 (same thing)

Step-by-step explanation:

(y2-y1/x2-x1)

(-1-4)/(2-(-3))=-5/5=-1

Answer:

-1

Step-by-step explanation:

The slope of a line can be written as [tex]\frac{\triangle{y}}{\triangle{x}}[/tex] or [tex]\frac{y_2 - y_1}{x_2-x_1}[/tex]. Plugging in the values gives us [tex]\frac{-1 - 4}{2 - (-3)} = \frac{-5}{5} = \boxed{-1}[/tex]

The speed of an object can be found by taking the distance it travels and dividing it by the time it takes to travel that distance. An object travels 100 feet in 2.5 seconds let the speed, S, be measured in feet per second. True or false: the equation

Answers

Answer:

True the speed S in in Feet/second

Step-by-step explanation:

In this problem we are required to solve for the speed of an object.

given that the expression to solve for the speed is expressed as

speed= distance/time

given data

distance=100 feet

time=2.5 seconds

substituting our given data into the expression we can solve for speed as

speed (S)=100/2.5

S= 40feet/seconds

upon substituting our data the speed S was found to be 40feet/s

True the speed S in in Feet/second

help find the slope of the line

Answers

Answer:

-3/5

Step-by-step explanation:

When finding the slope, think of it as rise/run.

Rise= up/down

run=left or right

So looking at the line, it is pointing towards -inf so the slope is negative

Then we look at 2 points.

i.e. (0,2) and (-5,5) and do the rise over run technique (or just subtract) and you get your answer!

The mean weight of the 28 bears at a zoo is 413 pounds. Fuzzy the bear, whose weight is 434 pounds, and Wuzzy the bear, whose weight is 505 pounds, were added to the zoo. What is the new mean of the weight of the bears at the zoo? Round your answer to the nearest tenth and enter pounds in the units box.

Answers

Answer:

416.8 pounds.

Step-by-step explanation:

The mean weight of the 28 bears at a zoo is 413 pounds.

The Total Weight of the 28 bears = Mean weight × number of bears

= 413 pounds × 28 bears

= 11564 pounds

Fuzzy the bear, whose weight is 434 pounds, and Wuzzy the bear, whose weight is 505 pounds, were added to the zoo.

This means the total number of bears

= 30 bears because two additional bears were added

What is the new mean of the weight of the bears at the zoo?

New Mean = 11564 pounds + 505 pounds + 434 pounds/30 bears

= 12503 pounds /30 bears

= 416.76666667 pounds

Approximately to the nearest tenth = 416.8 pounds.

While shopping at a music store, Rick bought 7 CD’s, all at the same price. The tax was $6.50 and the total was $66.00. What was the price of each CD?

Answers

Answer:

$8.50

Step-by-step explanation:

Subtract the tax from the total price:

66 - 6.50

= 59.5

Then, divide this by 7 to find the cost of each CD:

59.5/7

= 8.5

So, the price of each CD was $8.50

Answer:

8.50

Step-by-step explanation:

66-6.50=59.50

59.50 divided by 7 =8.50
