What is the equation for a line that has a slope of 3 and passes through (-1, 9)

Answer:

Distribute, then combine like terms, subtract 10 from both sides of the equation, simplify, divide both sides of the equation by the same term, and simplify to get your solution.

Step-by-step explanation:

1.) Distribute

6−2(4−5)=40

6−8+10=40

2.) Combine like terms

6a-8a+10=40

-2a+10=40

3.) Subtract 10 from both sides of the equation

-2a+10=40

-2a+10-10=40-10

4.) Simplify

subtract the numbers

-2a+10-10=40-10

-2a=40-10

subtract the numbers

-2a=40-10

-2a=30

-2a=30

5.) Divide both sides of the equation by the same term

-2a=30

[tex]\frac{-2a}{-2} =\frac{30}{-2}[/tex]

6.) Simplify

cancel terms that are in both the numerator or denominator

[tex]\frac{-2a}{-2} =\frac{30}{-2}[/tex]

a=[tex]\frac{30}{-2}[/tex]

Divide the numbers

a=[tex]\frac{30}{-2}[/tex]

a=-15

a=-15

7.) Solution

a=-15

The point which represents the cost of 4 pints is:

                     (4,8)        

Step-by-step explanation:

We are given that:

A market sells strawberries for $2.00 per pint.

Then, cost of 4 pints= $ 4×2.00

                                = $8.00

The point on the x coordinate represents number of pints

and the point on the y coordinate represents the cost in dollars

Hence, the point which represents the cost of 4 pints is:

                     (4,8)

Answer:

-9

Step-by-step explanation:

5x-3x=-10-8

2x= -18

x=-18/2

= -9

Solution of the expression is,

⇒ x = - 9

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

Equation is,

⇒ 5x + 8 - 3x = -10

Now, We can simplify as;

⇒ 5x + 8 - 3x = -10

⇒ 2x = - 10 - 8

⇒ 2x = - 18

⇒ x = - 18/2

⇒ x = - 9

Thus, Solution of the expression is,

⇒ x = - 9

Step-by-step explanation:

Simple Interest is defined as the interest that would be accumulated on a particular sum of money, loan, or investment kept or obtained from a financial institution.

The simple interest is $11.24

The formula for simple interest is given as:

I = P x R x T

Where

I = Simple Interest

P = Principal = $800

R = Interest rate = 1.71% = 0.0171

T = Time in years = 300 days

365 days = 1 year

300 days = ?

Cross Multiply

300 days x 1 year / 365 days

= 0.822 year

I = $800 x 0.0171 x 0.822

I = $11.24

Therefore, the simple interest is $11.24

Answer:

A-560

B-5600

Step-by-step explanation:

to find the answer for A we need to divide 3360 by 6 which gives us 560.

check: 560 x 6 = 3360

To find the answer for B we need to multiply the answer for A (560) by 10 which gives us 5600

Answer:

A- the question asks the speed and  the speed formula is speed=distance÷time. So 3360÷6=560 mph

B- At this rate means at this constant speed which is 560 mph, how many miles can it travel in 10 hours. We will rearrange the speed formula to find the distance. distance=speed×time. So 560×10=5600 miles.

Step-by-step explanation:

Figure is missing, so i have attached it.

Answer:

it will clear the arch because the height of the archway of the bridge 5 feet from the center is approximately 12.76 ft

Step-by-step explanation:

The standard form of equation of an ellipse is;

x²/a² + y²/b² = 1

From the figure in the image attached, we can see that the radius is; a = 52/2 = 26 ft

While the value of b = 13 ft

Thus;

x²/26² + y²/13² = 1

x²/676 + y²/169 = 1

We want to find the height of the archway of the bridge 5 feet from the center.

Thus, we will plug in 5 for x to get;

5²/676 + y²/169 = 1

(25/676) + (y²/169) = 1

Multiply through by 676 to get;

25 + 4y² = 676

4y² = 676 - 25

y² = 651/4

y² = 162.75

y = 12.76 ft

Thus height of the truck is 12 ft and so it will clear the arch because the height of the archway of the bridge 5 feet from the center is approximately 12.76 ft

Height of the archway 5 feet from the center is required.

The height of the archway 5 feet away from the center is 12.757 feet.

Semi-major axis = [tex]a=\dfrac{52}{2}=26\ \text{feet}[/tex]

Semi-minor axis = [tex]b=13\ \text{feet}[/tex]

The formula for ellipse is

[tex]\dfrac{x^2}{a^2}+\dfrac{y^2}{b^2}=1\\\Rightarrow \dfrac{x^2}{26^2}+\dfrac{y^2}{13^2}=1[/tex]

At 10 feet is the width of the truck.

The truck is passing through the center so the [tex]x=\dfrac{10}{2}=5[/tex]

[tex]\dfrac{5^2}{26^2}+\dfrac{y^2}{13^2}=1\\\Rightarrow y=\sqrt{(1-\dfrac{5^2}{26^2})\times 13^2}\\\Rightarrow y=12.757\ \text{feet}[/tex]

Now [tex]y=12.757\ \text{feet}>12\ \text{feet}[/tex]

So, the height of the archway 5 feet away from the center is 12.757 feet.
