Answers

Answer:

D = 90°

E = 147°

F = 33°

Step-by-step explanation:

E is 147°, because it is vertical to the angle 147°

F is 33°, because 147* is its supplementary angle, or angles that add up to 180°

D is worth 90°, because its supplement is worth 90°

Marlo uses 252 lb of gravel to cover a garden plot of 36 ft2. How many pounds of gravel does it take to cover one square foot? How large an area could be covered with 315 lb of gravel?

Answers

The area and the amount of gravel are illustrations of proportions.

7 lb will cover an area of 1 square foot, while 315 lb will cover an area of 45 square feet.

The given parameters are:

[tex]252\ lb= 36ft^2[/tex]

The number of pound for an area of 1 square foot is calculated as follows:

[tex]x = 1ft^2[/tex]

So, we have:

[tex]x = 1ft^2[/tex]

[tex]252\ lb= 36ft^2[/tex]

Cross multiply

[tex]x \times 36 = 252 \times 1[/tex]

Divide both sides by 36

[tex]x = 7lb[/tex]

The area to be covered with 315lb gravel is calculated as follows:

[tex]315lb = y[/tex]

So, we have:

[tex]315lb = y[/tex]

[tex]252\ lb= 36ft^2[/tex]

Cross multiply

[tex]y \times 252 = 36 \times 315[/tex]

[tex]y \times 252 = 11340[/tex]

Divide both sides by 252

[tex]y = 45[/tex]

Hence, 7 lb will cover an area of 1 square foot, while 315 lb will cover an area of 45 square feet.

Substitution would be the best method for solving which system?
O x = 6
2x - 3y = 8
3x - 2y = 18
4x + 5y = 60
O x + y = 7
x - 4y = 12
O y = 2x
x + y = 28

Answers

Answer:

The last one

Step-by-step explanation:

Because it tells you what y is

Answer:

Assuming its asking which is the easiest one to use substitution its the last one: y= 2x : x + y = 28

Step-by-step explanation:

Because y and x are already one opposite sides you can substitute y in the 2nd equation with 2x. So you'll get 3x = 28 so x = 9.333333334. Then you plug your answer for x in the original equation to get y = 18.666666667

Answer:

A. f(x) = x^2 -3x -10

Step-by-step explanation:

You can easily determine the correct equation by looking at a couple of table values.

The y-value for x=0 is -10, which is the constant in the quadratic formula. (eliminates choices B and C)

The y-value for x=1 is -12, which is the sum of coefficients in the quadratic formula. For choice A, the sum of coefficients is 1 -3 -10 = -12. For choice D, the sum of coefficients is 1 +3 -10 = -6. The value for choice D does not match the table, but the value for choice A does.

The function that represents the table is ...

f(x) = x^2 -3x -10

_____

Additional comments

If you don't have equations to test, and you want to write your own equation, there are a couple of ways to do that. One is to look at the differences of y-values, and the differences of those.

The sequence of y-values shown is ...

30, 18, 8, 0, -6, -10, -12

The sequence of differences of these numbers, starting with 18-30 = -12 is ...

-12, -10, -8, -6, -4, -2

The sequence of differences of these numbers is ...

2, 2, 2, 2, 2

The fact that they are constant tells you a quadratic (degree = 2) will describe the table.

We can find the coefficients a, b, c in the quadratic formula f(x) = ax^2 +bx +c as follows. First, we define d1 as the first of the sequence of differences (-12), and d2 as the value of the second differences (2). And we'll let x0 and y0 be defined as the first of the x-values (-5) and y-values (30).

The formulas for the coefficients (a, b, c) can be found from ...

a = (d2)/2 = 2/2 = 1

b = (d1) -a(2·(x0) +1) = -12 -1(2·(-5) +1) = -12 +9 = -3

c = y0 -x0(a·x0 +b) = 30 -(-5)(1·(-5) +(-3) = 30 -40 = -10

As we noted above, the y-value corresponding to x=0 is also this c value. When the table includes x=0 and x=1, those can be used to simplify the finding of the formula coefficients.

These computations tell us f(x) = x^2 -3x -10, as above.

If you have to do this again, it might be useful to make a note of the expressions for 'a', 'b', and 'c' that we showed here, along with the definitions of the variables we used in them.

Another way to find the formula for f(x) is to make use of a calculator or spreadsheet capable of quadratic regression. Give it three (x, y) pairs from the table, and it can tell you the formula coefficients. This is illustrated by the attachment.
