The equations x minus 2 y = 1, 3 x minus y = negative 1, x + 2 y = negative 1, and 3 x + y = 1 are shown on the graph below. On

a coordinate plane, there are 4 lines. Green line goes through (0, negative 1) and (1, negative 1). Orange line goes through (negative 1, negative 1) and (0, 1). Pink line goes through (0, 1), and (2.5, negative 1). Blue line goes through (0, 1) and (negative 2.5, negative 1). Which system of equations has a solution of approximately (0.6, –0.8)? x + 2 y = negative 1 and 3 x + y = 1 x minus 2 y = 1 and 3 x + y = 1 x minus 2 y = 1 and 3 x minus y = negative 1 x + 2 y = negative 1 and 3 x minus y = negative 1

What are the steps to solving this?
Archy [21]

Answer:

64 cubic metres

Step-by-step explanation:

The triangular pyramid volume formula resembles the volume formula for any other pyramid or cone:

V = A * H / 3

where:

A is the area of the pyramid's base

H is the height from the base to the point

In other words: the volume of a triangular pyramid is one-third of the product of the base area and the pyramid's height.

8 x 6 / 2 to find area of base = 24

x 8 = 192

192 / 3 = 64

Hope this makes sense. If you would like, I can l1nk to a very useful website, or I can explain it further.

If a function is defined by the formula y equals 2x + 1 + that domain is given by the set 3, 5, 7, 9 then which set represents t
Mariulka [41]

Answer:

{7, 11, 15, 19}

Step-by-step explanation:

The function is defined by the formula y = 2x + 1 ........ (1)

Now, domain of the function are given to be {3, 5, 7, 9}

Hence, from equation (1), at x= 3, y = 2 × 3 + 1 = 7

Now, at x = 5, y = 2 × 5 + 1 = 11

Again, at x = 7, y = 2 × 7 + 1 = 15

Finally, at x = 9, y = 2 × 9 + 1 = 19

Therefore, the range of the corresponding domain of this function is given to be {7, 11, 15, 19}. (Answer)

For what values of a are the following expressions true?/a+5/=-5-a
katovenus [111]

Explanation:

The expression is given below as

|a+5|=-5-a

Concept:

We will apply the bsolute rule below

\begin{gathered} if|u|=a,a>0 \\ then,u=a,u=-a \end{gathered}

By applying the concept, we will have

\begin{gathered} \lvert a+5\rvert=-5-a \\ a+5=-5-a,a+5=5+a \\ a+a=-5-5,a-a=5-5 \\ 2a=-10,0=0 \\ \frac{2a}{2}=\frac{-10}{2},0=0 \\ a=-5,0=0 \end{gathered}

Hence,

The final answer is

a\leq-5

Marilyn uses a credit card with a 19.9% APR compounded monthly to pay for car repairs totaling $991.38. She can pay $410 per mon
Leokris [45]
Marilyn's finance charge at the end of the first month will be
  $991.38 × 0.199/12 = $16.44
The balance subject to the next month's finance charge will be
  $991.38 +16.44 -410.00 = $597.82

The finance charge at the end of the second month will be
  $597.82 × 0.199/12 = $9.91
The balance remaining after the second payment will be
  $597.82 +9.91 -410.00 = $197.73

The finance charge applied at the end of the third month is
  $197.73 × .199/12 = $3.28
so Marilyn can make one final payment of
  $197.73 +3.28 = $201.01
to pay off the balance.

In all, Marilyn has paid 2×$410.00 +201.01 = 
  $1021.01 . . . . . . . . corresponds to the first choice

_____
In real life, Marilyn's credit card may not accrue any finance charge until after the first statement on which the charge appears. Thus the total cost of the purchase may be only $1004.02. The attached spreadsheet shows the beginning balance and the finance charges for each month for the two different scenarios.
