Answer 2

Answer:

Step-by-step explanation:

Please, include the instructions.

I'm assuming you want to solve this system of linear equations for z and w, assuming that k is an unknown constant.

Use the method of elimination by addition and subtraction.  To eiiminate w, multiply all four terms of the first equation by 10, obtaining:

10 z + 10w - 30 = 10k

6z   - 10 w        = 80

Then 16z - 30 - 80 = 10k, or

16z  -110 = 10k,  Simplifying this, we get:

     

      10(k + 11)  

z = ---------------

            16

Substituting this expression for z into the first equation, we get:

(10/16)(k + 11) + w - 3 = k.  We must solve this for w:

-(10/16)(k + 11) + w - 3 = k), or

-(10/16)(k + 11) - w + 3 = -k

Then -(10/16)(k + 11) + 3 + k = w

and so the solution, in terms of the unknown constant k, is

      10(k + 11)  

(     --------------,  -(10/16)(k + 11) + 3 + k   )

            16

Given the formula y = mx + b, what is the slope of a line, m, if x = 5, y = 7, and b =10?
A. The slope 3/5 ·
B. The slope 5/3 ·
C. The slope - 3/5 ·
D. The slope - 5/3 ·

Answers

The answer is:
C. The slope -3/5
Because -3/5 times 5 is -3 and when you combine -3 and 10 the answer is 7 and 7=7 (the y)

If the area of a trapezoid is 28 m with a height of 14 m in with one of the base being 1 m to find the length of the second face

Answers

The area of a trapezoid is basically the average width times the altitude, or as a formula:
Area = h ·

b 1 + b 2
2


where
b1, b2 are the lengths of each base
h is the altitude (height)
Recall that the bases are the two parallel sides of the trapezoid. The altitude (or height) of a trapezoid is the perpendicular distance between the two bases.

In the applet above, click on "freeze dimensions". As you drag any vertex, you will see that the trapezoid redraws itself keeping the height and bases constant. Notice how the area does not change in the displayed formula. The area depends only on the height and base lengths, so as you can see, there are many trapezoids with a given set of dimensions which all have the same area.

Describe the slope of the line.

Answers

the slope of the line is positive.
the slope is 4/3.

it’s positive because the line is rising/going up
the slope is 4/3 because it rises 4 units and goes to the left 3 units.

The slope of line from the given graph is 4/3.

The coordinates of line from the given graph are (4, 3) and (1, -1).

What is slope of a line?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

Now, put (x1, y1) = (4, 3) and (x2, y2) = (1, -1) is slope formula, we get

Slope = (y2-y1)(x2-x1)

= (-1-3)/(1-4)

= 4/3

Therefore, the slope of line from the given graph is 4/3.

Find the slope of the line y=1/6x+3/2

Answers

y = mx + b

The coefficient of x is the slope.

So the slope is 1/6. m = 1/6

The slope of the given line is  [tex]\frac{1}{6}[/tex].

The slope of a line is the ratio of the amount that y increases as x increases some amount. Slope tells you how steep a line is, or how much y increases as x increases.

When a linear equation is written in slope intercept form, the slope of the line can easily be identified. The slope is "m" or the coefficient of x in the equation.

According to the question ;

The given line is

[tex]y = \frac{1}{6} x + \frac{3}{2}[/tex]

By comparing with the standard equation of the line .

y = mx + c

[tex]m = \frac{1}{6} \\ c = 6 \\[/tex]

Now ; slope of the line = m =   [tex]\frac{1}{6}[/tex]

The slope of the line is  [tex]\frac{1}{6}[/tex] .

Your brother received two job offers. One offers a regular wage, and the other offers hourly pay. Both are 40-hour-per-week jobs. The wage job includes two weeks of paid vacation, but the hourly job offers only unpaid vacation. The annual salary for the wage job is $35,000. The hourly job pays $17 per hour. Which job pays more?

Answers

Answer:

The job with the fixed wage is better and pays more.  

Step-by-step explanation:

The annual salary for the fixed wage job is $35,000 and the hourly job is $35,360 because 17x40(no of hours needed to work in a week) x52(no of weeks in a year)

The salary of 2 weeks on the hourly job is $1360 and the paid job offers paid vacation for 2 weeks so $35,360 - $1360 is $34,000 and that is $1000 less than the wage job.

Answer:

9 and 8 are linear and 10 is non linear

Step-by-step explanation:

an = dn - c

The an stands for the nth term of the pattern. So a1 is the first term and a2 is the second term of the pattern. The d is the difference between each of the terms. The n stands for the term you're calculating. If you're calculating the third term, then n is 3. And c is a constant that you'll need to calculate.

For example, the linear number pattern of 1, 3, 5, 7, 9, … has an equation of:
