Answer:
how many boxes is the line on
Y=-3/4x+5 because you get the y by itself
Answer:
The labels for cost line will be at 5.5$, 11$ , 16.5 $ for 1,2 and 3 pounds of cherries respectively.
Step-by-step explanation:
Given:
A double line shows 4 pounds of cherries 22 dollars .
To Find:
Cost for 1 pound ,2 pounds and 3 pounds of cherries.
Solution:
A double number line represents the two different quantities values and their relationship.
<em>(Refer the attachment)</em>
So 4 pounds corresponds to 22 dollars.
the proportion is,
4:22
=1:22/4
i.e 1 pound corresponds to 22/4 dollars
1 pound =22/4
1 pound of cherry=5.5 dollars
Similar for 2 pounds
2pounds = 2*(22/4)
=2*5.5
=11 dollars
Now for 3 pounds
3 pounds =3*(22/4)
=3*5.5
=16.5 dollars.
The second number line will be allocated the points for 1,2 and 3 pounds of cherries as 5.5,11,16.5 respectively.
Answer:
-2. 46
- 9.54
Step-by-step explanation:
- 2x²+12x-7=0
- 2x²+12x+18= 25
- 2*(x²+6x+9)=25
- 2*(x+6)²= 5²
- x+6= 5√2/2 ⇒ x= 5√2/2 -6 ≈ -2. 46
- x+6= -5√2/2 ⇒ x= -5√2/2 -6 ≈ - 9.54
