3x +
9y = -27
x + y = -1
Answer:
(x, y) = (3, -4)
Step-by-step explanation:
A graphical solution is often quick and easy.
(x, y) = (3, -4)
_____
These equations can be solved algebraically by dividing the first by 3, then subtracting the second.
(3x +9y)/3 -(x +y) = (-27)/3 -(-1)
x +3y -x -y = -9 +1
2y = -8
y = -4
x = -1 -y = -1 -(-4) = 3 . . . from the second equation
The solution is (x, y) = (3, -4).

(2x + 3) (2 - 8) = 0,
Step-by-step explanation:
(2x + 3) (2-8)=0
2x( 2-8)+3(2-8)= 0

Answer:
$55.25
Step-by-step explanation:
15% of $65: [tex]\frac{65}{1}[/tex] × [tex]\frac{15}{100} = \frac{975}{100}[/tex] $975/100 = $9.75$65 - $9.75 = $55.25I hope this helps!
$55.25 is the cost of the coat after the sale.
Step-by-step explanation:
Given:
Price of the coat = $65
Percentage of discount = 15%
To find:
The cost price of coat after the sale
Solution:
Cost price of coat = $65
Percentage of discount = 15%
The amount of discount will be 15% of the price of the coat.
Amount of discount :
[tex]=\frac{15}{100}\times \$65 \\=\$9.75[/tex]
The cost price of the coat:
[tex]=\$65-\$9.75=\$ 55.25[/tex]

I need HELLLPPPPP. A student bought concert tickets online. The total cost, c, in dollars, of t tickets can be
found using the function below.
c(t) = 87.50t + 12.50
If the student spent a total of $800 on tickets, how many tickets did she buy?
+/-
Answer:
The answer is 9.
Step-by-step explanation: Things to know: c is total cost and t tickets. 800 is the total cost so plug it in to c. You want to get t (tickets) alone.
original: c(t)=87.50t+12.50
Now with the 800: 800=87.50t+12.50
Subtract 12.50 to both sides: 787.5=87.50t
Divide 87.50 to both sides: 9=t

Considering only functions that have a rate of change less than that represented in the graph, which function has the greatest rate of change?
A. y = 7/6x + 2/3
B. y = 7/5x + 7/5
C. y = 6/5x + 11/5
D. y = 5/4x + 15/4
=======================================================
Explanation:
Slope is the same as the rate of change for any linear function. We ignore the y intercepts.
The slopes of the four equations, A through D, are: 7/6, 7/5, 6/5, and 5/4
This is because each equation is in y = mx+b form with m as the slope.
Convert each fractional slope into decimal form
7/6 = 1.167 approximately7/5 = 1.4006/5 = 1.2005/4 = 1.250We see that 7/5 produces the largest decimal, so 7/5 is the largest fraction of the four slopes.
Therefore equation y = (7/5)x+7/5 has the greatest rate of change.
