Which equation represents a like that passes through (4,1/3) and has a slope of 3/4?

1 answer:

7 0

The slope intercept form is y = mx + b
you need to find the equation that has a slope of 3/4 and passes through (4,1/3)

Plug in the given into the equation
y = 3/4x + b
to solve for the y-intercept, plug in the given coordinate that the line passes through

1/3 = 3/4(4) + b
1/3 = 3 + b
subtract 3 from both sides
-8/3 = b

now back to the slope intercept equation
y = mx + b
plug in the slope and y-intercept
y = 3/4x - 2 2/3
or
y = 3/4x - 8/3

Hope this helps :)

If the endpoints of segment AB are A(-4,5) and B(2,-5),<br><br>please help!

Answer:

$d = \sqrt[2]{34}$

Step-by-step explanation:

We are solving for the segment of AB. Note that it is a line segment, so there will be end points, those being A(-4, 5) & B(2, -5).

Use the following distance formula:

<em /> $distance$ <em> </em> $(d) =$ $\sqrt{(x_{2} - x_{1})^{2} + (y_{2} - x_{2})^2 }$

Let:

Point B(2 , -5) = (x₁ , y₁)

Point A(-4 , 5) = (x₂ , y₂)

Plug in the corresponding numbers to the corresponding variables.

$d =$ $\sqrt{(-4 - 2)^{2} + (5 - (-5))^{2} }$

Simplify. Remember to follow PEMDAS. First, solve the parenthesis, then the powers, then add, and then finally square root.

$d = \sqrt{(-6)^{2} + (5 + 5)^{2} } \\d = \sqrt{(-6 * -6) + (10)^2} \\d = \sqrt{(36) + (10 * 10)} \\d = \sqrt{36 + (100)} \\d = \sqrt{136}$

Simplify:

$d = \sqrt{136} = \sqrt{2 * 2 * 2 * 17} = \sqrt[2]{17 * 2} = \sqrt[2]{34}$

$d = \sqrt[2]{34}$ is your answer.

Calculate the first difference between 7, and where 7,-688. 2

Nataly_w [17]

The difference between the numbers given is 6.882.

<h3>How to illustrate the information?</h3>

Based on the information given, it should be noted that difference means subtraction.

The difference between the numbers given will be:

= 7 - (7 - 6.882)

= 7 - 0.118

= 6.882

The sphere shown has a diameter of 24 inches. Which choice is closest to its surface area? Use 3.14 to approximate pi.

tamaranim1 [39]

I don't know what your choices are, but I did the questions for you.
R=D/2, R=12, R=radius,
SA= 4 times 3.14 12 times 12, so,
SA=1809.557368, if you round it to two decimal places, it'll be,
1809.56, so the answer is 1809.56in. squared.
