Answer:

<h2><u><em>8 in</em></u></h2>

Step-by-step explanation:

we can solve with an equation

15 : 20 = 6 : x

x = 20 * 6 : 15

x = 120 : 15

x = 8

the total weight w in pounds of a tractor trailer capable of carrying 8 cars depends on the number of cars c on the trailer.
aliya0001 [1]
Given that t<span>he total weight w in pounds of a tractor trailer capable of carrying 8 cars depends on the number of cars c on the trailer and that the situation is represented by the function rule w = 37,000 + 4,200c

To graph the function, we draw the coordinate axis with the number of cars in the horizontal (x) axis and the weight of the truck (in thousands) in the vertical (y) axis.

The horizontal axis is calibrated starting from 0 with increment of 1 and the vertical axis is calibrated starting from 0 with the increment of 5.

From the given function rule, when c = 0 (i.e. when the truck is carrying no car) the weight of the truck is given by w = 37,000 + 4,200(0) = 37,000

Thus, the graph will start at point (0, 37).

Also when the truck is carrying 8 cars, the weight of the truck is given by w = 37,000 + 4,200(8) = 70,600

Thus, the graph will end at point (8, 70.6).

If a bank represents deposits with positive numbers and withdrawals as negative numbers, what could 10 + (-60) represent?
sineoko [7]

Answer:

A $10 deposit followed by a $60 withdrawal

Step-by-step explanation:

The 10 is positive, so it would represent a deposit, and the 60 is negative, so it would represent a withdrawal.

Consider a circle whose equation is x2 + y2 + 4x – 6y – 36 = 0. Which statements are true? Check all that apply. To begin conver
umka21 [38]

Answer:

1) False, to begin converting the equation to standard form, each side must be added by 36. 2) True, to complete the square for the x terms, add 4 to both sides, 3) True, the center of the circle is at (-2, 3), 4) False, the center of the circle is at (-2, 3), 5) False, the radius of the circle is 7 units, 6) False, the radius of the circle is 7 units.

Step-by-step explanation:

Let prove the validity of each choice:

1) To begin converting the equation to standard form, subtract 36 from both sides:

Let consider the following formula and perform the following algebraic operations:

(i) x^{2} + y^{2} + 4\cdot x - 6\cdot y  - 36 = 0 Given

(ii) x^{2} + 4\cdot x + y^{2} - 6\cdot y - 36 = 0 Commutative Property

(iii) (x^{2} + 4\cdot x + 4) - 4 + (y^{2} - 6\cdot y + 9) - 9 -36 = 0 Modulative/Associative Property/Additive Inverse Existence

(iv) (x+ 2)^{2} - 4 + (y - 3)^{2} - 9 - 36 = 0  Perfect Trinomial Square

(v) (x+2)^{2} +(y-3)^{2} = 4 + 9 + 36 Commutative Property/Compatibility with Addition/Additive Inverse Existence/Modulative Property

(vi) (x+2)^{2} + (y-3)^{2} = 49 Definition of Addition/Result

False, to begin converting the equation to standard form, each side must be added by 36.

2) True, step (iii) on exercise 1) indicates that both side must be added by 4.

3) The general equation for a circle centered at (h, k) is of the form:

(x-h)^{2}+ (y-k)^{2} = r^{2}

Where r is the radius of the circle.

By direct comparison, it is evident that circle is centered at (-2,3).

True, step (vi) on exercise 1) indicates that center of the circle is at (-2, 3).

4) False, step (vi) on exercise 1) indicates that the center of the circle is at (-2, 3), not in (4, -6).

5) After comparing both formulas, it is evident that radius of the circle is 7 units.

False, the radius of the circle is 7 units.

6) After comparing both formulas, it is evident that radius of the circle is 7 units.

False, the radius of the circle is 7 units.
