Answer:
y=4x-23
Step-by-step explanation:
(7, 1) and (1,8)
slope = (8 - 1)/(1-7) = -7/6
so
y - 1 = -7/6(x - 7)
y - 1 = -7/6 x + 49/6
y = -7/6 x + 55/6
answer
A. first one
y = -7/6 x + 55/6
Answer:
164 and 287
Step-by-step explanation:
Their difference is 7-4 = 3 ratio units, so each ratio unit must stand for 123/3 = 41.
Then the numbers are 4·41 and 7·41, or 164 and 287.

Answer:
Step-by-step explanation:
<em>Step 1: Determine quantity per liquid</em>
liquid 1=7/8 cup
liquid 2=9/10 cup
<em>Step 2: Derive expression to calculate total amount of mixture</em>
The expression below can be derived;
T=a+b
where;
T=total amount of mixture
a=total amount of liquid 1
b=total amount of liquid 2
In our case;
a=7/8 cup
b=9/10 cup
replacing;
T=(7/8)+(9/10)=1 31/40 cups
The total amount of mixture=1 31/40 cups
