Answer:
Go with the 2nd choice.
Step-by-step explanation:
When using proportions to solve for unknown quantities, you need to keep the same units on the same side. This means keep "ft" on the top side and "mi" on the bottom side.
Answer:
y = -7
Step-by-step explanation:
y2 - y1 / x2 - x1
-7 - (-7) / -2 - (-3)
0/1
= 0
y = 0x + b
-7 = 0(-2) + b
-7 = 0 + b
-7 = b
Domain is another word for the x value. so, this question just asking us to solve for y when x = 7
first, substitute in x
y = 3(7) -4
and then solve for y
y = 21 - 4
y = 17
so, the range is 17 when the domain is 7
The factorisation of the given expressions is as follows;
- a) p²y²– 2py + 1 = (py -1)²
- b) a²y² -2aby +b² = (ay - b)²
<h3>Factorization using identities</h3>
The given identity is;
From the given identity, we can conclude that;
In the expression (a);
- py represents a in the identity and 1 represents b in the identity.
In the expression (b);
- ay represents a in the identity and b represents b in the identity.
Hence, the factorised expressions are as represented above.
