Answer: 500 chicken feed and 200 careful calculators
Step-by-step explanation:
2x+3y=1,600
40x+50y=30,000
those are your first two equations
your first matrix equation for A is 2, 3,40,50 and B is 1,600 and 30,000 when you enter those in your calculator and 500 and 200 should be your result.
Answer:
Step-by-step explanation:
altitude = sqrt(6*8) = 4*sqrt(3)
Use the Pythagorean Theorem to derive x
altitude^2 + 18^2 = x^2
48 + 18^2 = x^2
x^2 = 342
x = 3*sqrt(38)
x = 18.49
Answer:
best approximate is 78 F. to find x, count number of hours between 5 am and 2 pm (which is 9). Substitute 9 into the equation and solve. hope this helps!
Step-by-step explanation:
Answer:
the answer is 2
Step-by-step explanation:
x=-3
y=4
w=-6
xy/w
= -3×4/-6
= -12/-6
= 2/1
= 2
Factors are (y - 7)(5y - 43)
Step-by-step explanation:
- Step 1: Given, 5x² + 12x + 4 = (x + 2)(5x + 2)
Now, to factor 5(y - 9)² + 12(y - 9) + 4. Here, y - 9 can be equated to x if both equations are compared.
- Step 2: To factorize, substitute y - 9 for x in the factors (x + 2)(5x + 2)
⇒ Factors = (y - 9 + 2)[5(y - 9) + 2]
= (y - 7)(5y - 45 + 2)
= (y - 7)(5y - 43)
