Mathematics
1 answer:
Darya [45]3 years ago
7 0

Answer:

(1 \frac{1}{3}, 2 \frac{1}{3} )

Step-by-step explanation:

Given the 2 equations

7x - y = 7 → (1)

x + 2y = 6 → (2)

Multiplying (1) by 2 and adding to (2) will eliminate the y- term

14x - 2y = 14 → (3)

Add (2) and (3) term by term to eliminate y

15x = 20 ( divide both sides by 15 )

x = \frac{20}{15} = \frac{4}{3} = 1 \frac{1}{3}

Substitute this value of x into either of the 2 equations and solve for y

Substituting in (2)

\frac{4}{3} + 2y = 6

2y = 6 - \frac{4}{3} = \frac{14}{3} ( divide both sides by 2 )

y = \frac{7}{3} = 2 \frac{1}{3}

Solve: 2 ( X + 5 ) = 3X + 1 Show your work
Korvikt [17]

Answer:

x = 9

Step-by-step explanation:

Given

2(x + 5) = 3x + 1 ← distribute left side

2x + 10 = 3x + 1 ( subtract 2x from both sides )

10 = x + 1 ( subtract 1 from both sides )

9 = x

How do you graph y=7/2x-2
RoseWind [281]
You can either make a table using any numbers you would like (I would suggest -5 to 5) and then graphing the rule

ex. (7/2)(-5)-2 = -19.5 (I multiplied (7/2) by -5 and then subtracted 2) 


Or you can put the rule in a graphing calculator and check the points from there
