Answer:
function
A set of ordered pairs where each first element is paired with one and only one second element and no element in either pair is without a partner.
Step-by-step explanation:
Question 1: Calculate the slope, x-intercept and y-intercept of a linear equation, f(x) = 5x + 4 ?
Solution:
Given,
f(x) = 5x + 4
The general form of a linear equation is,
f(x) = mx + c
So,
Slope = m = 5
Substitute f(x) = 0,
0 = 5x + 4
5x = -4
x = −45
The x-intercept is (−45, 0)
Substitute x = 0,
f(x) = 5(0) + 4
f(x) = 0 + 4
f(x) = 4
The y-intercept is (0,4)

Step-by-step explanation:
The correct answer is:
2 pieces, with 1/12 m left over.
Explanation:
To find the number of 1/3 meter pieces she can cut from a 3/4 meter ribbon, we divide:
3/4÷1/3
To divide fractions, flip the second one and multiply:
3/4×3/1
To multiply fractions, multiply straight across:
(3*3)/(4*1) = 9/4
4 will go into 9 two times with 1 left over, so this simplifies to 2 1/4; this means she can cut 2 pieces this length.
2 pieces that are 1/3 meter long is a total of 2(1/3) = 2/3 m. To find out how much is left, subtract:
3/4 - 2/3
Common denominator is 12:
3/4 = 9/12 and 2/3 = 8/12
9/12 - 8/12 = 1/12
There is 1/12 of a meter left.
Answer:
She can make maximum 2 pieces
Amount left = m
Explanation:
1- getting the maximum number of pieces:
We know that the total length is m and that each piece would measure
To get the number of pieces, we would simply divide the total length by the length of each piece as follows:
number of pieces = pieces
We will need to round down to get the maximum number of pieces.
This means that the maximum number of pieces that she can cut is 2 pieces
2- getting the leftover:
We calculated that she can make two pieces each of length m
This means that:
total length of two pieces = m
We know that the total length is m
This means that:
leftover = m
Hope this helps :)
The answer is:
To solve the problem, remember to set your calculator in "degree mode"
So, we are given that the angle A is equal to 68°
So, we have that:
Hence, we have that:
Have a nice day!
