Answer: y= 2x+10

Step-by-step explanation:
Slope Intercept form: y=mx+b
You want to find the equation in terms of y. So, therefore, isolate 2y
2y=20+4x
Divide both sides by 2
y=10+2x

Regarding the Canadian coins, 1 toonies will be equal to 8 quarters.

From the information given, it was stated that 16 Canadian coins, 16 quarters is equal in value to 2 toonies.

Therefore, it's important to find the constant of proportionality. This will be:

y = kx

where y = quarter

k = constant

x = toonies

16 = 2k

k = 16/2

k = 8

The value next to 1 quarter will be:

y = kx

y = 1 × 8

y = 8

Therefore, the toonies will be equal to right quarters.

The tail length of an alligator whose body length is 4.2 feet will be 3 feet.

Direct proportion or direct variation is the relation between two quantities where the ratio of the two is equal to a constant value. Mathematically, direct proportionality is represented by a straight line and it equation is of the form -

y = kx

k = y/x

where [k] is the constant

Given is an alligator's tail length [T] varies directly as its body length [B]. An alligator with a body length of 2.8 feet has a tail length of 2 feet.

We can write as -

tail length [T]  [tex]\alpha[/tex]  body length [B].

Therefore -

T/B = K    [Constant]

We can write -

T₁/B₁ = T₂/B₂

2/2.8 = T₂/4.2

T₂ = (2 x 4.2)/2.8

T₂ = 3 ft

Therefore, the tail length of an alligator whose body length is 4.2 feet will be 3 feet.

Answer: It is not possible for f(x) = 5(2^x) to equal to 200.

Step-by-step explanation: I put it in a calculator. When x = 5.321, the output is approximately 199.871380105. But when x = 5.322, the output is about 200.009968414. This means that the output of exactly 200 is impossible.

The unit rate of the given parts are :

1)  37.037 index cards

2) 25.64 index cards

An item's unit rate is its price for one of it. This is expressed as a ratio with a one as the denominator. For instance, if you covered 70 yards in 10 seconds, you covered 7 yards on average every second. Seven yards in one second and 70 yards in ten seconds are both ratios, but only one of them is a unit rate.

The denominator of a unit rate is always 1. Therefore, divide the denominator by the numerator so that the denominator equals one in order to determine the unit rate. The unit rate is 50km/5.5 hours = 9.09 km/hour, for instance, if 50km are traveled in 5.5 hours.

1 ) $4.05 for 150 index cards

Thus for $1 we will get = 37.037 index cards

2) $1.17 for 30 index cards

Thus for $1 we will get = 25.64 index cards

By isolating the variable y in the left side of the linear equation, we will get:

y = 4x - 10

Here we have a linear equation and we want to solve this for y, to do this, we need to isolate the variable y in one of the sides of the equation.

The linear equation is:

5y + 10 - x = 4y + 3x

Moving all the terms with y to the left side and the others to the right side, we get:

5y - 4y = 3x - 10 + x

If we simplify this we get:

y = 4x - 10

This is the linear equation solved for y.

[tex]y=\boxed{-14.380}\;x^2+\boxed{299.970}\;x+\boxed{-950.851}[/tex]

$39

Step-by-step explanation:

Create 5 additional columns on the given table for x², x³, x⁴, xy, and x²y.

Calculate the values and add the sum of each column.

(See attachment 1).

Use the matrix equation for determining the parabolic curve, entering the sums from attachment 1:

[tex]\displaystyle a \sum x{_i}^4+b \sum x{_i}^3+c \sum x{_i}^2=\sum x{_i}^2y_i[/tex]

[tex]\implies 74446.015625a+6046.90625b+520.25c=248662.875[/tex]

[tex]\displaystyle a \sum x{_i}^3+b \sum x{_i}^2+c \sum x{_i}=\sum x{_i}y_i[/tex]

[tex]\implies 6046.90625a+520.25b+48.5c=22987.5[/tex]

[tex]\displaystyle a \sum x{_i}^2+b \sum x{_i}+c n_i=\sum y_i[/tex]

[tex]\implies 520.25a+48.5b+5c=2313[/tex]

Solve for a, b and c using a calculator:

Insert these values (rounding to 3 decimal places) into the quadratic formula [tex]y=ax^2+bx+c[/tex] :

[tex]\large\boxed{y=-14.380x^2+299.970x-950.851}[/tex]

To find the profit (y) for a selling price of 16.75, substitute x = 16.75 into the found quadratic equation:

[tex]\implies y=-14.380(16.75)^2+299.970(16.75)-950.851[/tex]

[tex]\implies y=39.157...[/tex]

Therefore, the profit is $39 to the nearest dollar.

Note: Attachment 2 is the two-variable regression analysis as calculated by an online graphing calculator, proving that the y-value is 39 (nearest whole number) when x=16.75.

The lower and upper bounds of w is 3 and 4.16

What is Upper bound and Lower bound?

An element of K that is bigger than or equal to every element of S is referred to as an upper bound or majorant of S in mathematics, specifically in order theory. In contrast, a lower bound or minorant of S is defined as an element of K that is smaller than or equal to every element of S. A set that has an upper (or lower) bound is said to be majorized[1] (or minorized, respectively) from above (or below) by that constraint.

Given that,

w =(x + y)/z

x = 2.5 ± 0.5,

y = 1.5 ± 0.5

and, z = 1.1 ± 0.1

Substituting the values in the equation to find upper bound

x = 3.0

y = 2.0

z = 1.2

Then,

w = (3 + 2)/1.2

w = 5/1.2

w = 4.16

Substituting the values in the equation to find lower bound

x = 2.0

y = 1.0

z = 1.0

Then,

w = (2 + 1)/1

w = 3/1

w = 3

Hence, The upper bound of w is 4.16

The lower bound of w is 3

Given that, twice a​ number, increased by ​three, is between negative one and nine.

The relation between two expressions that are not equal, employing a sign such as ≠ ‘not equal to’, > ‘greater than’, or < ‘less than’.

Let the unknown number be x.

Now, twice a​ number, increased by ​three = 2x+3

The given expression is between negative one and nine

-1 < 2x+3 < 9
