Answer:
100
Step-by-step explanation:
sum the parts of the ratio, 4 + 5 + 1 = 10 parts
Fiona gets 40 sweets which is 4 parts of the ratio
Divide Fiona's share by 4 to find the value of one part of the ratio
40 ÷ 4 = 10 ← 1 part of the ratio
The total number of sweets is 10 parts , thus
number of sweets in total = 10 × 10 = 100
Put common terms in evidence and simplify:
If u add it to a grapghing calcauter
u will get as your points
(-1.2) (6.994)
y2 - y1
---------
x2 - x1
3 - 1 2 1
------- = -------- = --------
4 - 0 4 2
Find the y-intercept:
1 = 1/2(0) + b
1 = 0 + b
-0 -0
1 = b
The slope-intercept equation is:
y = 1/2x + 1
so its D
