Answer:
x=5, y=-2. (5, -2).
Step-by-step explanation:
2x+3y=4
3x+4y=7
----------------
3(2x+3y)=3(4)
-2(3x+4y)=-2(7)
----------------------
6x+9y=12
-6x-8y=-14
-----------------
y=-2
2x+3(-2)=4
2x-6=4
2x=4+6
2x=10
x=10/2
x=5
Answer:34.56
Step-by-step explanat 103.68 divded by 3 = 34.56
Answer:
x>-2
Step-by-step explanation:
Hi there!
We are given the inequality 7+7(x+4)>21, and we want to solve it
Solving an inequality is a lot like solving an equation; we want to isolate x on one side by itself.
So to start, we'll preform the distributive property on 7(x+4) (multiply x by 7, then multiply 4 by 7 and add those two together).
7+7x+28>21
Now combine like terms.
7x+35>21
Subtract 35 from both sides
7x>-14
Divide both sides by 7
x>-2
Hope this helps!
60 / 5 = 12 miles per gallon
36 miles = 12 miles / gal * x gallons
divide by 12
36/12 =x gallons
3 =x
He needs 3 gallons
The equation of the line will be y = 4x. Then the correct option is A.
<h3>What is the equation of line?</h3>
The equation of line is given as
y = mx + c
Where m is the slope and c is the y-intercept.
Writing an Equation from a Table
A 2-column table with 6 rows. Column 1 is labeled x with entries 8, 12, 16, 20, 24, 28. Column 2 is labeled y with entries 2, 3, 4, 5, 6, 7.
Then at (2, 8) and (3, 12), we have
y – 8 = [(12 – 8) / (3 – 2)] (x – 2)
y – 8 = 4x – 8
y = 4x
Then the correct option is A.
