Use the linear combination method to solve this system of equations. What is the value of 3x+7y=3 X-7y=1

Jacob and Joe are selling cheesecakes for a school fundraiser customers can buy New York style cheesecake and strawberry cheesec

Viefleur [7K]

Step-by-step explanation:

Given data

Let the cheese be x

And strawberry be y

So

6x+6y=96-------1

x+4y=52----------2

Solving 1 and 2 simultaneously

Let us multiply equation 2 by 6 we have

6x+6y=96

6x+24y=312

-0-18y=-216

18y=216

y=216/18

y=12

Put y=12 in equation 2

x+4*2=52----------2

x+8=52

x=52-8

x=44

cheese =44

strawberry =12

The following scatter plot shows the data for NCAA quarterbacks comparing their attempted passes to completed passes.

Elanso [62]

The line of the best fit is shown in the picture which is approximate near the dots.

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

The slope and y-intercept can be found using the formula below:

$\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2} \\\\\rm c = \dfrac{\sum y -m \sum x}{n}$

We have a given a scatter plot shows the data for NCAA quarterbacks comparing their attempted passes to completed passes.

We can draw a line of best fit y = mx + c

Thus, the line of the best fit is shown in the picture which is approximate near the dots.

The volume of prism A is 60 cubic units, and the volume of prism B is half the volume of prism A. What is the value of a?

Alexxx [7]

Answer:

a=3.91

Step-by-step explanation:

V=a^3

since volume of B is Half of A then : V of A = 2 volume of B

a^3=2a^3

a^3 for A=60

or ∛a = ∛60= 3.91

volume of B =1/2 A =30

Diano4ka-milaya [45]

Answer:

its either B,C, OR D, because if you add the numbers inside the parenthesis and times it by the number in front of the : ( ), then you get 180 and that's what the number is that you should get. From Jacob in middle school in Florida.

Step-by-step explanation:

Where (because) is, to the end of the whole sentence is the explanation. thank you for understanding if you do

just got it wrong and the answers turn out to be B,and D.
