What solution do you obtain for the systems of equations by graphing? What is the exact solution?

Pani-rosa [81]

Answer:

(1.63,4.18)

Step-by-step explanation:

1) look at the graph below: they intersect at about (1.5,4)

lets solve the systems by substitution:

since both equations are equal to y lets substitute the second equation into the first:

-6x+14=5x-4

-6x-5x=-14-4

-11x=-18

x=1.63

lets substitute x in the first equation:

5(1.63)-4=4.18

Hope this helps!

jonathan goes to th store and purchases 3 pencils for 0 .28 each, and x number of erasers for 0.38each write an expression that

Anestetic [448]

Keywords

linear equation, variables

Step 1

Define the variables

Let

x-----> number of erasers

y-----> total cost

we know that

$y=3(0.28)+(0.38)x$

$y=0.84+(0.38)x$ ------> this is the linear equation that represent the situation

therefore

the answer is

$y=0.84+(0.38)x$

Venn diagram is the representation of set in a graphical form

See attachment for the set of multiples of 2, 13, 3 and 6

Given

$Numbers = \{8,9,10,11,12,13\}$

Let

$A \to$ Multiples of 2

$B \to$ Multiples of 8

$C \to$ Multiples of 6

$D \to$ Multiples of 13

First, we split the numbers in set of the given multiples

$A: \{8, 10, 12\}$

$B = \{8\}$

$C =\{12\}$

$D = \{13\}$

Digit 9 does not belong to any of these set

Set B and set C are proper subsets of set A.

This means that sets B and C will be inside set A in the Venn diagram

So, we have:

$A = \{B,10,C\}$

Since 9 does not belong to any of the sets, it will not be inside any of sets A, B, C or D
