Graphing<br>solve a system of equation by graphing ​
Alex787 [66]

SOLUTION:

Point \ (1,3)

<h2>Explanation:</h2>

Let's use the following System of Linear Equations in Two Variables in order to solve this exercise:

\begin{array}{c}(1)\\(2)\end{array}\left\{ \begin{array}{c}y=2x+1\\y=-4x+7\end{array}\right.

So we can graph these lines using two points.

For eq (1):

y=2x+1 \\ \\ If \ x=0 \ then \ y=2(0)+1 \therefore y=1 \\ \\ If \ y=0 \ then \ 0=2x+1 \therefore x=-\frac{1}{2} \\ \\ \\ Points: \\ \\ (0,1) \\ \\ (-\frac{1}{2},0)

So graph a line that passes through these two points. This is the red line shown below.

For eq (2):

y=-4x+7 \\ \\ If \ x=0 \ then \ y=-4(0)+7 \therefore y=7 \\ \\ If \ y=0 \ then \ 0=-4x+7  \therefore x=\frac{7}{4} \\ \\ \\ Points: \\ \\ (0,7) \\ \\ (\frac{7}{4},0)

So graph a line that passes through these two points. This is the blue line shown below.

<em>The solution of this system of equation is the point of intersection, which is (1,3)</em>

Rezolvati problema prin metoda figurativa:
Anna35 [415]

Ne este dat numărul total de elevi = 30.

Să presupunem că numărul de băieți este egal cu numărul de fete.

Dacă împărțim 30 cu 2, obținem 15.

Deci, numărul de băieți = 15 și numărul de fete = 15 dacă ambele sunt egale.

"Dar numărul de fete este mai mult de 2 băieți."

Astfel putem scădea 1 din 15 și adăugăm 1 din 15.

După adăugarea a 1 din 15, ajungem

15 + 1 = 16.

Și scăzând de la 1 la 15, ajungem acolo

15-1 = 14.

Deci, numărul de băieți este de 14 și numărul de fete este de 16

At the baseball stadium, the price for popcorn is $5.88 for 3 bags. If you want to buy 7 bags of popcorn, how much will it cost?
4vir4ik [10]
The answer will be $13.72 for 7 bags of popcorn.

to find this answer, you first take 5.88 and divide it by 3 to find out how much one bag costs.

the answer to 5.88/3 is 1.96, so you multiply 1.96 by 7 to get the answer of how much 7 bags of popcorn will cost.

hope this helps!
