Answer: 64 ................ :)
Step-by-step explanation:
Answer:
1.
8x + 6y = 28
9x + 3y = 39
Set to equal y.
8x + 6y = 28
6y = -8x + 28
y = -8/6x + 28/6
y = -4/3x + 14/3
9x + 3y = 39
3y = -9x + 39
y = -9/3x + 39/3
y = -3x + 13
Set equal to each other.
-4/3x + 14/3 = -3x + 13
Combine like terms.
5/3x = 25/3
Multiply by 3/5
x = 5
Plug x in.
y = -3(5) + 13
y = -15 + 13
y = -2
(5, -2)
2.
-2x - 9y = -3
-7x - 9y= -33
Set equal to y.
-2x - 9y = -3
-9y = 2x - 3
y = -2/9x + 3/9
y = -2/9x + 1/3
-7x - 9y= -33
-9y = 7x - 33
y = -7/9x + 33/9
y = -7/9x + 11/3
Set equal to each other
-2/9x + 1/3 = -2/9x + 1/3
0 = 0
infinitely many solutions
Answer:
degree 5, leading coefficient 1
Step-by-step explanation:
When the sign of the end behavior matches that of x, the leading coefficient is positive, and the degree is odd.
One possibility is ...
degree 5, leading coefficient 1
First of all, 2400=0.6x is the equation
Now, we use cross multiplication
2400/1 = 3/5x
2400*5 = 3x
12,000 = 3x
12000/3= 4000
<u>The total fundraiser goal is $4,000.</u>
