find x and y
y= -3x=-19
5x+8y=0
Answer:
x= -8; y= 5
Step-by-step explanation:
5x + 8 ( -3x -19) =0
5x -24x -152 =0
5x -24x= 152
-19x = 152
x= -8
y= -3x -19
y= -3(-8) -19
y= 5
5x + 8y = 0
5(-8) + 8(5) =0
-40 + 40 = 0

He had a beginning cash balance of $4,800, $103,000 in total cash sales, $3,500 for utilities, $2,600 in loan payments, and $5,500 for marketing cost.
Total cash inflow = $4,800 + $103,000 = $107,800
Total cash outflow = $3,500 + $2,600 + $5,500 = $11,600

A sequence is defined by the following: an = 4n – 1 What is a1? What is a8?.
Answer:
a^1=1
a^8=16,384
Step-by-step explanation:
The original equation of a^n=4^n-1 uses n as a placeholder variable for whatever value is needed to solve the equation. For the first question, which gives 1=n, substituting 1 into the equation gives you the answer of 1. 1-1=0. You can not have any number to the power of zero however, so due to the multiplicative identity, you end up with a positive 1.
The second one we are given 8=n. 8-1 equal 7. 4 to the power of seven (multiply 4 by itself 7 times) gets you 16, 384.
Given the sequence defined as [tex]a_{n} = 4n - 1[/tex], [tex]a_{1} =3\ and\ a _ {8} = 31[/tex].

- THIS IS A 50 POINT QUESTION
Answer:
40
Step-by-step explanation:
Sum of all angles of triangle = 180°
∠W + ∠X + ∠Y = 180
10x + 17 + 2x - 9 + 3x + 7 = 180
10x + 2x +3x + 17 - 9 + 7 = 180
Combine like terms
15x + 15 = 180
15x = 180- 15
15x = 165
x = 165/15
x = 11
∠Y = 3x +7 = 3*11 + 7 = 33 + 7 = 40
Answer:
X is 11 and after substitution y is 40

Answer:
x = 6
FE = 28
Step-by-step explanation:
The triangles are similar so their side lengths are proportional
we can use that proportional value to find x and FE
(5x-2)/42 = (4x+2)/39 cross multiply expressions
195x - 78 = 168x + 84 get like expressions to the same side of the equation
195x - 168x = 84 + 78
27x = 162 divide both sides by 27
x = 6 now to find FE replace x with 6 in the expression
5x - 2 = 5×6 - 2
FE = 28
Is (0,7) a solution to the equation 2x+y=6
Answer:
No
Step-by-step explanation:
2(0)+7
=0+7
=7
therefore,(0,7) is not a solution to the equation 2x+y=6
0=×
7=y
Answer: no it isn’t
Step-by-step explanation: this is super simple so do solve this you have know your x and y values on coordinate points in this case (0,7) our x here is 0 and our y is 7 (the x will always be the first number and the y will be the last)
Here we are given a equation all we have to do is plug 0 for x and 7 for y.
2(0)+7=6
2 x 0= 0
So: 0+7=7
7 does NOT equal to 6 therefor (0,7) is NOT a solution

Answer:
c = 14.9
Step-by-step explanation:
use the pythagorean thereom:
a² + b² = c²
a² = 11 × 11 = 121
b² = 10 × 10 = 100
c² = 121 + 100 = 221
now find the square root of 221:
√221 = 14.866...
round to the nearest tenth:
the 6 next to the 8 means round up.
so the hypotenuse is 14.9
