Determine which point is the solution to the given system.
KatRina [158]

Answer:

D

Step-by-step explanation:

We equate both the y's and solve for x algebraically:

-\frac{4}{7}x+16=-\frac{2}{7}x+12\\16-12=-\frac{2}{7}x+\frac{4}{7}x\\4=\frac{2}{7}x\\x=\frac{4}{\frac{2}{7}}\\x=14

Now taking the value x= 14 and putting it in the 1st equation would give us y:

y=-\frac{4}{7}x+16\\y=-\frac{4}{7}(14)+16\\y=8

Hence the solution is (14,8), answer is D

What is the answer to 3x{5x[10+5(500-100)+399]}
scZoUnD [109]
500-100=400
5(400)=2000
399+10=409
2000+409+2409
5(2409)=12045
3(12045)-36135
so in total it's equal to 36135

Answer:

  No, the clay will not pour out easily. I know this because the angle of the truck bed is less than 50°, which is the minimum angle for easy pouring.

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that ...

  Sin = Opposite/Hypotenuse

If α represents the angle of the truck bed, this means ...

  sin(α) = 9/15

We can find α using the inverse sine function:

  α = arcsin(9/15) ≈ 36.87°

We note this angle is less than 50° so we expect the clay will not pour out easily.
