Answer:

A, B, and C

Step-by-step explanation:

a). -6 ÷ 2 x 5 1/3

= -3 x 5 1/3

= -16

b). 24 ÷ (-3) + 1/2

= -8 + 1/2

= -7.5

c). 36 ÷ 4 x (-2)

= 9 x -2

= -18

d). -54 ÷ (-9) x (-3 2/3)

6 x -3 2/3

= -22

Answer: [tex]y = 5^x+2[/tex]

The 2 is not in the exponent.

=====================================================

Explanation:

As x gets smaller and smaller, going off into the negative direction forever, the expression [tex]5^x[/tex] will approach 0. This is because we're computing stuff like 5^(-1) = 1/5 = 0.2 and 5^(-2) = 1/25 = 0.04 and so on. The decimal values are approaching 0 but never actually arrive there. The range of [tex]y = 5^x[/tex] is [tex](0,\infty)[/tex]

Adding on the 2 at the end will shift everything up so that the range is now [tex](2,\infty)[/tex]. Refer to the graph below.

The parenthesis in interval notation mean we do not include that endpoint as part of the set. Saying something like [tex](2,\infty)[/tex] is the same as saying [tex]2 < y <\infty[/tex] when talking about the range.

Answer:

$31.96

Step-by-step explanation:

To find how many gallons you need, divide 320 by 34.

[tex]\frac{320}{34} =9.4 (rounded-to-the-nearest-cent)[/tex]

So now that we know we need 9.4 gallons, we multiply 9.4 times the price per gallon ($3.40)

9.4 x $3.40 = $31.96

Answer:

Zander starts with 7,000; Carly starts with 5,000

Step-by-step explanation:

1 - Visually solving

Looking at the final value (31,000) one could interpret the sums of the numbers tripled and doubled respectively would need to equate to 31,000.

Taking off the additional zeros could also prove beneficial. To get 31, one of the numbers tripled or doubled would need to either be 11 or 21. 11 is a prime number, so that can be cancelled out. 7 multiplied by 3 (triple) produces 21.

12 - 7 = 5. Solving for the leftover 5 which would be doubled, you would get 10.

10 + 21 = 31.

2 - Algebra

x - Zander; y - Carly

To begin with you should need the initial formula.

x + y = 12,000

Your second formula would then take into consideration the changes made to x and y

3x + 2y = 31,000.

Using process of elimination or substitution, (either method works), you will find x = 7,000 and y = 5,000

Answer:

THis is a function.

Step-by-step explanation:

If you draw a straight line vertically, it won't intersect more than one point of the line. This is called the vertical line test, and if the line you drew passes the line on the graph more than once, its not a function.

Answer:

The distance between the points is 7.81 (to the nearest hundreth)

Step-by-step explanation:

The distance formula between two points in the coordinate plane is:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Put,

[tex]J(x_1,y_1)=(-2,-1)\\A(x_2,y_2)=(3,-7)[/tex]

Hence,

[tex]d=\sqrt{(3-(-2))^2+(-7-(-1))^2} \\d=\sqrt{(3+2)^2+(-7+1)^2} \\d=\sqrt{5^2+(-6)^2} \\d=\sqrt{25+36} \\d=\sqrt{61} \\d=7.810[/tex]

Answer:

Step-by-step explanation:

6(1)(-2) -2(1)(-2)^2 - 3(1)(-2) +(-2)^2

-12 -8 +6 +4

=-10

-10 is the value of the given polynomial.

A polynomial is a mathematical equation that solely uses the operations addition, subtraction, multiplication, and non-negative integer exponentiation of variables. Variables are sometimes known as indeterminate in mathematics. Majorly used polynomials are binomial and trinomial.

First, we can simplify the polynomial by combining like terms:

[tex]2x^2y + 4x^2y + 3xy^2 - 5xy^2 - 3xy + y^2\\= (2x^2y + 4x^2y) + (3xy^2 - 5xy^2) + (-3xy + y^2)\\= 6x^2y - 2xy^2 - 3xy + y^2[/tex]

Now, to evaluate for x = 1 and y = -2, we substitute those values into the simplified expression:

[tex]6(1)^2(-2) - 2(1)(-2)^2 - 3(1)(-2) + (-2)^2\\= 6(-2) - 2(4) + 6 + 4\\= -12 - 8 + 6 + 4\\= -10[/tex]

Therefore, the value of the polynomial for x = 1 and y = -2 is -10.
