Answer:
x = 1
Step-by-step explanation:
-4v+5x=17 give that (x,-3) is the solution
so x coordinate is = x (unknown)
y coordinate is = -3
substitute the value of y in -4y+5x=17
therefore
-4(-3)+5x=17
12+5x=17
5x=17-12
5x=5
x=5/5
x=1

Answer:
Pythagorean Theorem and Sine
Step-by-step explanation:
you could use pythagorean theorem to find the 3rd side, then use inverse sine of c.
Using the equation a2 + b2 = c2
Subtract 13squared from 5squared
169-25
then take the square root of the answer- which is 12
then do the inverse of sine
that should give you the missing angle
Answer:
b. 63 units
Step-by-step explanation:
The breakeven point occurs when the revenue is equal to the expenses. It means that the profit is 0. So, for the Basic model, the revenue is the sell less the costs: $41 - $15 = $26.For the Deluxe model, the revenue per unit is 0 ($45 - $45).
So, calling x the Basic model units, ad y the Deluxe model units, the total revenue will be: 26x, which must be equal to the expenses = $1,310.40:
26x = 1310.40
x = 50.4 units
y = x/4, because for 1 Deluxe model four Basic models are selled.
y = 50.4/4 = 12.6 units
The total units for breakeven point is 50.4 + 12.6 = 63 units.
Both x and y equal 2.
2•2=4 + 2•2=4
4+4=8
2+2=4
