so first you need to find the slop between (1,3) and (4,5)
5-3/ 4-1 = 2/ 3= m
using that slope you put it into the slope intercept formula
y=mx+b
use the coordinate (2,-5)
-5= 2/3 (2)+b
-5= 1.33+b subtract 1.33 on both sides
-6.33=b
plug b and m into the slope intercept formula
ANSWER: y=2/3x-6.33
Answe12800 miles
Step-by-step explanation:a year is 12 months, and mile round trip means there and back. so 532x24 for the 24 trips that equals 12768. 12768 rounded to the nearest hundreds is 12800
Answer: 1¹¹/₂₀ litres
Step-by-step explanation:
The fractions need to be added.
Find a common multiple for them.
Common multiple = 20
Divide the multiple by the denominator of the fraction and multiply the numerator by the result you get:
= 1¹¹/₂₀ litres
7 hrs 12 minutes
6 hrs 46 minutes
6 hrs 53 minutes
--------------------------add
19 hrs 111 minutes ......... = (19 * 60) + 111 = 1140 + 111 = 1251 minutes
1251 / 3 = 417 minutes <== her average delivery....or 6 hrs 57 minutes
Answer:
Step-by-step explanation:
A bag contains yellow and blue blocks in the ratio 1:3
Sum of Proportion = 1 + 3 = 4
There are 8 more blue blocks than yellow blocks.
b = y + 8
y = b - 8
(a) How many yellow blocks are there?
For yellow block
= 1/4 × x = ( b - 8)
(b) How many blue blocks are there?
3/4 × x = ( y + 8)
