Solve for k in the equation 12 = 4(k - 6)

Answers

Answer 1

Answer:

12 = 4 (k - 6) (use the distributive property to get rid of the parentheses)

12 = 4k -24 (add 24 to both sides to isolate the k-term)

36 = 4k (divide both sides by 4 to get k all alone)

k = 9 (your answer)

Line q passes through the points (4, 6) and (0, 6). What is the equation for the line which is perpendicular to q and passes through the point (–2, 3)?

Answers

Answer:

        x = -2

Step-by-step explanation:

The slope of q:  

                       [tex]m_q=\dfrac{6-6}{4-6}=0[/tex]

It means the line q is parallel to X-axis. Therefore any line perpendicular to q is parallel to Y-axis.

Any line parallel to Y-axis is:  x = x₀, where x₀ is the x-coordinate of any point the line passing through.

(-2, 3)    ⇒   x₀ = -2

Values in the question are missing ; we could get some input for the missing values and solve the question asked :

Jaclyn is training for a long bike ride. Right now, her longest ride is 36 miles. She plans to add 2 miles each week to her longest ride. Use a linear equation to determine the length of Jaclyn's longest ride after 6 weeks. Do not include units in your answer.

Answer:

48 miles

Step-by-step explanation:

Given that:

Longest ride (initial) = 36 miles

Additional miles per week = 2 miles

y(x) = mx + c

c = initial ride ; m = rate (increase in miles per week) ; x = number of miles per week

Longest ride after 6 weeks will be :

[Longest ride (initial) + additional miles per week * number of weeks]

Longest ride after 6 weeks :

36 miles + (2 * 6)

36 + 12

48 miles after 6 weeks

Sweet = $1.25

Amount left = $8.50 - $1.25 = $7.25

Find amount left after giving to 2 friends:

Answer:

measure of Arc FJ is 80 degrees.

Step-by-step explanation:

Key skills: High School Geometry, One Variable Equations, Angles

1)Let's look at the diagram thoroughly

2) The 2 thing we can get are:

Angle HKG and Angle IKJ are vertical angles (which means they are congruent). Angle HKG + Angle GKF + Angle FKJ = 180 (Since they all form a straight angle - A straight angle is 180 degrees in measure.)

3) First we can use the fact that Angle HKG and Angle IKJ are vertical angles. This makes them congruent (Or equal in size)

We can then solve for x by making the equation: 3x-22=x+10

4) Solve this by moving the x's to one side, and the numbers to the other. You would then get: 3x-x=10+22

3x-x= 2x           10+22=32

2x=32

Divide by 2 on both sides and x=16.

5) We get that x=16. Now to find the measure of Arc FJ, we need to use the fact that Angle HKG + Angle GKF + Angle FKJ =  180

What we want to find is Angle FKJ. The measure of Angle FKJ would be the measure of Arc FJ

6) We can make an equation: x+10+74+Angle FKJ=180

Solve this --> x=16, so substitute it in16 + 10 + 74 + Angle FKJ=180100 + Angle FKJ = 180Angle FKJ = 80 degrees

If Angle FKJ is 80 degrees, then Arc FJ measures 80 degrees.
