Answer: y = 1/2 x 7
Step-by-step explanation:
Get the apparent line that generally passes through the mean values of the values represented in the scatter plot. Find the Slope.
The easiest way is to the difference between the highest and lowest y-values (or the average of two of the highest and lowest) So around about 17.5 - 8.5 = 9 Divide by the difference in x-values 18- 1 = 17 9/17 ≈ .53 Round to .5 ≈1/2
Of the choices given, only the last one has the correct slope. If you were to graph this line, passing through the apparent mean of the values (about half the points above and half below the line) it would intersect the y-axis at about y=7
Answer:
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
1. You have that she substituted 
into the simplified expression and the result was -4.
2. Therefore, if you substitute into all the expressions shown in the options, you will see that the result of the expression is -4, as you can see below:
Answer:
2y is a coefficient.
9 is a constant.
6x and 5x are like terms.\
2y is term
these are the ones right
Step-by-step explanation:
You can say : 15% ⇒ ? if 100% ⇒ 32.50 $
so next you can say : 15/100 = ?/32.50 ⇒ ? = (15/100) × 32.50 = 15 × 32.50 ÷ 100 = 4.875 ⇒ so the answer is 4.785 $ ;D i hope this will be helpful :))
It's b. Group all the pounds together and all the volumes together. Small packages weigh 30 lbs (30x), lg pkgs weight 65 lbs (65y) and together they weigh at most 3800 lbs. So 30x + 65y <= 3800 (they divided each of those terms by 5 to get 6x + 13y <= 760). Next take the volumes: small pkgs have a volume of 4 ft^3 (4x) and lg pkgs have a volume of 9 ft^3 (9y) and together they are no more than 400 ft^3. So 4x + 9y <= 400. It's b.
