Solve the system of linear equations by graphing. Round the solution to the nearest tenth.
jeyben [28]

Answer:

The approximate solution to the system is (1.2, 4.4)

x = 1.2 and y = 4.4

Step-by-step explanation:

The solution of the system of linear equations equation y = –0.25x + 4.7 and y = 4.9x – 1.64 is shown in the attached graph. The red line represents the equation y = –0.25x + 4.7 and the blue line represents the equation  = 4.9x – 1.64.

The solution of the system of equations is their point of intersection shown on the graph.

The point of intersection is (1.231, 4.392). To the nearest tenth, it is (1.2, 4,4). So x = 1.2 and y = 4.4.

So the approximate solution to the system is (1.2, 4.4)

Solve equation 3x-5y=7 5x-2y=-1 by elimination
kakasveta [241]

Answer:

x = -1, y = -2.

Step-by-step explanation:

Using the elimination method,

multiply the first eqn by 2 and the 2nd eqn by 5.

6x - 10y = 14

25x - 10y = -5

Subtract one of the new equations from the other

-19x = 19

x = -1

Sub x=-1 into the 2nd eqn

-5 - 2y = -1

y = -2

Hence x = -1, y = -2.

3+2/3(3-x)<-7 please help I am stuck
asambeis [7]
Solve the problem then state if it's true or false- this is an order of operation problem. 3+2/3(3-X) this is the problem. Now distribute, 3+ 2/3(3)- 2/3(x)= 3+2- 2/3x so the final expression would be 5-2/3x I don't know about the <-7 part but that's the solution to the first one

What is another way to write the equation 7/8x3/4=-6
prohojiy [21]

Another way to write the equation is 7x + 54 = 0

<h3>How to rewrite the equation</h3>

Given the equation;

\frac{7}{8}x + \frac{3}{4}  = -6

Find the LCM on the left side, which is 8

\frac{7x + 6}{8}  = -6

Cross multiply

7x + 6 = -6 × 8

7x + 6 = -48

Collect like terms

7x = -48 - 6

7x = -54

Take all to one side

7x + 54 = 0

Thus, another way to write the equation is 7x + 54 = 0
