Answer:

Dan bought 3 pencils and each pencil cost 5 cents.You know logically that it took 15 cents. He would need one nickle for each pencil he bought, or 3 nickles.

Step-by-step explanation:

Problem One (left panel)

Question A

The y intercept happens when x = 0
That being said, the y intercept is 50. It was moving when the timing began.

Question B

The rate of change = (56 - 52)/(3 - 1) = 4/2 = 2 miles / hour^2 (you have a slight acceleration.

Question C

60 = a + (n-1)d
60 = 50 + (n - 1)*2
10/2 = (n - 1)*2/2
5 = n - 1
6 = n

The way I have done it the domain is n from 1 to 6

Question 2 (Right Panel)

Question A

The equation for the table is f(x) = 3x - 3 which was derived simply by putting all three points into y = ax + b and solving.

f(0) = ax + b
-3 = a*0) + b
b = - 3
So far what you have is
f(x) = ax - 3
f(-1) = a*(-1) - 3 but we know (f(-1)) = -6
- 6 = a(-1) - 3 add 3 to both sides
-6 +3 = a(-1) -3 + 3
-3 = a*(-1) Divide by - 1
a = 3
f(x) = 3x - 3 Answer for f(x)
The slope of f(x) = the coefficient in front of the x
f(x) has a slope of 3
g(x) has a slope of 4

Part B

f(x) has a y intercept of - 3
g(x) has a y intercept of -5
f(x) has the greater y intercept.
-3 > - 5

Joelle is working on a school report in a word processor. She wants to place a figure which is 13.09 cm wide so it apperars cent

Hello Croary

We would first need to subtract 13.09cm from 21.59cm which will be 8.5cm, with the left over space, divide in half

8.5/2 = 4.25cm

[2,4,6]

Step-by-step explanation:

GIVEN EQUATION : 2X+3≥7

i.e, 2x≥7-3

i.e, 2x≥4

i.e, x≥4/2

i.e, x≥2

it's represent number should be greater than or equal to 2

The only number which follows the inequality from the set is 2,4&6

What is the slope of the line with the equation of y=-2/3x that passes through the point (2,1)

kow [346]

Answer:

$-\frac{2}{3} = m$

Step-by-step explanation:

In the Slope-Intercept Formula, $y = mx + b$ , b represents the y-intercept, and the rate of change [slope] is represented by m, so the slope is −⅔.

I am joyous to assist you anytime.
