Answer:
<h2>4x - y = 7</h2>
Step-by-step explanation:
Put the values of x = 1 and y = -3 to the equations of a line and check the equality:
1. 4x - y = 7
4(1) - (-3) = 4 + 3 = 7 CORRECT
2. 2x + 5y = 4
2(1) + 5(-3) = 2 - 15 = -13 ≠ 7
3. 7x - y = 15
7(1) - (-3) = 7 + 3 = 10 ≠ 15
4. x + 5y = 21
1 + 5(-3) = 1 - 15 = -14 ≠ 21
Answer:
23
Step-by-step explanation:
if you have $16.10, he could buy 23 bluebarry muffins. Because if yo do
16.10 / 0.70 you woould get 23, and if you put that in the equasion you would
get this, P=$0.70(23) . 23 * 0.70 = 16.1
Answer:
13 1/8 units³
Step-by-step explanation:
(see attached for reference)
Volume = Length x Width x Height
= 1 1/2 x 3 1/2 x 2 1/2 (convert to improper fractions)
= 3/2 x 7/2 x 5/2
= (3 x 7 x 5) / (2 x 2 x 2 )
= 105/8
= 13 1/8 units³
A square root is a number times itself .
for example 2x2 is a square root .
so, any number times itself is a square root
