Answer:

  C:  2x+2y=-2

Step-by-step explanation:

The equation that makes the system have infinitely many solutions is one that is dependent on the given equation. The easiest way to make a dependent equation is to multiply the given equation by some constant.

Here, choice C has the original equation multiplied by 2, so it is dependent on the given equation.

  x + y = -1   ⇒   2(x + y) = 2(-1)   ⇒   2x + 2y = -2 . . . . matches choice C

(f+g)(x) is equivalent to f(x) + g(x)
So, you would do (-x^2 +6x-1) + (3x^2 -4x-1)
This is equal to 2x^2 +2x -2

Final answer:
A. (f+g)(x) = 2x^2 +2x -2

How can you use partial quotients to find 684 divided by 57?
shusha [124]

Answer: 684 divided by 57=12

Step-by-step explanation:(with reference to the figure)

To find  684 divided by 57 by partial quotients .

Here dividend= 684 and divisor =57

Step 1: Write easy factors of divisor that is nearest to the dividend as follows

57×2=114

57×3=171

57×5=285

57×10=570(nearest easy factor)

Step 2: Now subtract 570 from 684 ,we get 114 then subtract 114=57×2 from it we get 0.

Step 3: Adding the factors we have used in step 1 and 2 ,it will give required quotient=10+2=12

i.e. 684=57(10)+57(2)

Answer:

The volume is 356 in^3 , which agrees with the second answer option listed.

Step-by-step explanation:

Recall that the volume of a pyramid is the product of the area of its base(B)  times the pyramid's height (h), divided by three:

V=B*\frac{h}{3}

For our case, the area of the base "B" is the area of a square of side = 8 inches. That is the area B is:

B=(8 \,in)^2=64\,in^2

Now we can include this value and the value of the pyramid's height (h=12 in) in the formula for the volume to give the answer:

V=B*\frac{h}{3}=64\,in^2\,\frac{12\,in}{3} =256\,in^3

Vedmedyk [2.9K]

Answer:

The total cost of purchase of Matt and Natalie are $29.41

Step-by-step explanation:

We are given the following in the question:

Cost of clothing without tax = $27.75

Tax percentage = 6%

Amount of tax on clothing =

=6\%\times 27.75\\\\=\dfrac{6}{100}\times 27.75 \\\\=1.665\approx \$1.66

Total cost of purchase =

=Total bill without  tax + Amount of tax

=27.75+1.66\\=\$29.41

Thus, the total cost of purchase of Matt and Natalie are $29.41
