Answer:
No
Step-by-step explanation:
The table shows two differnt outputs for the number 7 which isn't how a function works so the answer is no
0.3. Add 1.9 and 0.1 which equals 2r. Then divide two by both sides and you get 0.3.
D = sqrt (x2 - x1)^2 + (y2 - y1)^2
d = sqrt (-8-7)^2 + (-9-(-1)^2
d = sqrt (-15^2)^2 + (-8^2)^2
I am getting : (-15^2) + (-8^2)
Answer:
1/ab
Step-by-step explanation:
Complete question
Find the slope of the line containing the points whose coordinates are(a,1/b) and (b,1/a)
Slope is expressed as;
m = y2-y1/x2-x1
Substitute the coordinate values
m = (1/a - 1/b)/b -a
m = (b-a)/ab ÷ b-a
m = (b-a)/ab × 1/b-a
m = b-1/b-a × 1/ab
m = 1 × 1/ab
m = 1/ab
Hence the slope is 1/ab
You need to make a proportion. Cross multiply and divide.
eggs 2 x
cookies 4 10
(2)(10) = 4x
20 = 4x
x = 5
You will need 5 eggs to make 10 dozen cookies
