You can subtract 2y from both sides of the first equation and then plug that (x = 7 -2y) into the second one to get:
14 - 4y + y = 5 -->
14 - 3y = 5 -->
-3y = -11 -->
y = 11/3 -->
x = 2/3
why is x=6 a solution to the proportion 192/36=32/x
Answer:
They're both equal each other!
Step-by-step explanation:
Because 32/6 is 5.33... on the calculator and when you divide 192/36 is 5.33 and so on. X = 6 is the solution because both of these divisors equal each other!!! Hope this helps!

Solve the equation for x.
x2 = 9
= 2x = 9
= x = 9 ÷ 2 ( transposing ×2 from LHS to RHS changes ×2 to ÷2 )
= x = 4.5
Therefore , x = 4.5 .

what is 5 8/9 as a decimal
Answer:
5.88889
Step-by-step explanation:
5 8/9
=53/9
=5.88889
Answer:5.88889
Step-by-step explanation:
you would multiply 5 by the denominator and you would get 45 then add 45 by the numinator and you would get 53 and you would get an improper fraction which is 53/9 and then you divide 53 by 9 and get 5.88889.
Line g has an equation of y = -9x - 9. Perpendicular to line g is line h, which passes
through the point (9,-5). What is the equation of line h?
Write the equation in slope-intercept form. Write the numbers in the equation as proper fractions, improper fractions, or integers.
Answer:
y=1/9x - 6
Step-by-step explanation:
perpendicular lines have slops that are the negative reciprocal of one another. After you find the slope you then plug in the point to find b using the equation: -5=1/9(9) + b .

What is the equation of the line through (-1,-5) and perpendicular to y = = 5x + 5?
Answer:⬇️
Step-by-step explanation:
Reorder 5 5 and 5x 5 x . Using the slope-intercept form, the slope is 5 . The equation of a perpendicular line to y=5x+5 y = 5 x + 5 must have a slope that is the negative reciprocal of the original slope.
IM 18 MY number is 920-896-1733 if want to text ;0
Answer:
Don’t wanna
Step-by-step explanation:
5z-12z-10=18+7z
Im not sure how to do this
Answer:
The answer is z = -2
Step-by-step explanation:
You combine like terms.
Then subtract 7z from both sides.
Add 10 to both sides.
Then divide both sides by -14. (28/-14)
Which then equals to -2

Leslie is buying potatoes at a store. This graph shows the relationship between the number of pounds of potatoes she buys and the total cost.
The picture shows a line graph, titled Cost of Potatoes. The horizontal axis is labeled, Weight of Potatoes in pounds. The values shown on the horizontal axis are zero through five. The vertical axis is labeled Cost in Dollars. The values shown on the vertical axis are zero through five. The line on the graph starts at zero pounds and zero dollars. The line moves in the upward direction. It passes through the point two pounds and one and one-half dollars. It also passes through the point four pounds and three dollars.
Based on the graph, what is the unit cost, in dollars, of the potatoes?

Answer:
(f - g)(x) = -x² + 3x + 7 ⇒ D
Step-by-step explanation:
In the expression x - a, you will subtract a from x
Let us solve the question using this fact
∵ f(x) = 3x + 1
∵ g(x) = x² - 6
→ We need to find (f - g)(x), which means subtract g from x
∵ (f - g)(x) = (3x + 1) - (x² - 6)
→ The negative sign before (x² - 6) will change their signs
∵ - (x² - 6) = -(x²) + -(-6)
→ Remember (-)(+) = - and (-)(-) = (+)
∴ - (x² - 6) = -x² + 6
→ Substitute it in (f - g)(x)
∴ (f - g)(x) = 3x + 1 - x² + 6
→ Add the like terms
∴ (f - g)(x) = 3x - x² + (1 + 6)
∴ (f - g)(x) = 3x - x² + 7
→ Re-arrange the terms from the greatest power of x
∴ (f - g)(x) = -x² + 3x + 7
