Answer:

The slope of the graph of the equation of the line as 5x - 2y = 20 will be [m] = 5/2

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

The equation of a straight line can be also written as -

Ax + By + C = 0

By = - Ax - C

y = (- A/B)x - (C/A)

Given is the equation of the line as 5x - 2y = 20.

We have the equation of the line as -

5x - 2y = 20

2y = 5x - 20

y = (5/2)x - 10

[m] = 5/2

Therefore, the slope of the graph of the equation of the line as 5x - 2y = 20 will be [m] = 5/2

The growth in Nora's salary illustrates a geometric progression

The total amount earned over the 21 years is $1147059

The given parameters are:

Initial salary, a = 40000

Rate, r = 1 + 3% = 1.03

Number of years = 21

The sum of n terms of a geometric progression is represented as:

Sn = a((r^n) - 1)/(r - 1)

So, we have:

S21 = 40000 * ((1.03^21) - 1)/(1.03 - 1)

Evaluate

S21 = 1147059

Hence, the total amount earned is $1147059

Step-by-step explanation:

89*6.5

Answer:

x = 13

Step-by-step explanation:

Supplementary means 180 degrees.

Since we are finding the supplement, we are going to add both angles together and solve for x.

3x + 11 + 17x - 91 = 180

~Combine like terms

20x - 80 = 180

~Add 80 to both sides

20x = 260

~Divide 20 to both sides

x = 13

Best of Luck!

Answer:

Since the measure of both angles are supplementary, its easy to form the equation.

3x+11+17x-91 = 180

20x-80 = 180

20x = 100

x = 5

m<a = 3x+11

= 3(5)+11

= 15+11

= 26

m<b = 17x-91

= 17(5)-91

= 85-91

Option B

Answer:

B(x=4,x=5)

Step-by-step explanation:

Here,

[tex]x^{2} -9x+20=0[/tex]

We can find the value of x by various methods.

Method 1

By using formula

x=-b±√b²-4ac/2a

For ax²+bx+c=0

Here,

a=1, b=9, c=20

Putting the values.

x=-b±√b²-4ac/2a

x=-(-9)±√9²-4×1×20/2×1

Taking positive one.

[tex]x=\frac{-(-9)+ \sqrt{81-80} }{2} \\\\x=\frac{9+1}{2} \\\\x=5[/tex]

Taking negative one.

[tex]x=\frac{-(-9)- \sqrt{81-80} }{2} \\\\x=\frac{9-1}{2} \\\\x=4[/tex]

x=5,x=4

Method 2

[tex]\hookrightarrow x^{2} -9x+20=0\\\\\hookrightarrow x^{2}-4x-5x+20=0\\\\\hookrightarrow x(x-4)-5(x-4)=0\\\\\hookrightarrow (x-5)(x-4)=0[/tex]

x-5=0....I

x-4=0.....II

Solving equation I

x-5=0

x=5

Solving equation II

The gas mileage of the trucks is the number of miles traveled per gallon of gas

The truck that has the best gas mileage is (b) Truck A, because for every gallon the truck goes 19 miles.

As stated above, gas mileage measures the miles traveled by one gallon of gas.

This means that options (a) and (c) cannot be true, because these options measure the number of gallons used per mile

From the complete question, truck A uses 1 gallon for 19 miles, while truck B uses 1 gallon for 18 miles.

19 miles per gallon is greater than 19 miles per gallon

This means that truck A has the greater mileage

Hence, option (B) is true

Lewis has to pay $260 more to have his electricity and cable turned on because of his bankruptcy.

Bankruptcy is a legal proceeding involving a person or business that is unable to repay its outstanding debts.

Had Lewis not filed bankruptcy, he would have paid = 90+50+65+75

He would have paid (let us say amount A)= $280

After filing for bankruptcy he has to pay = 205+75+150+110

He has to pay (let us say amount B)= $540

Difference between amount A and amount B = $540-$280

Difference between amount A and amount B = $260

Therefore, Lewis has to pay $260 more to have his electricity and cable turned on because of his bankruptcy.

A number line is a representation of a graded straight line. The value that is farthest from 2 is √2.1.

A number line is a representation of a graded straight line that serves as an abstraction for real numbers, which are indicated by the symbol 'R'. A real number is considered to correspond to every point on a number line, and a point to every real number.

On the number line, positive numbers are on the right side of the number line while negative numbers are on the left side of the number line. Now, the value of all the given options can be written as,

[tex]\sqrt{2.1}=1.45 \\\\\sqrt{2.4}=1.55\\\\\sqrt{2.5}=1.58\\\\\sqrt{2.9}=1.7[/tex]
