3 + j / 11 = 2
11* (3+j/11) = 2*11
3 + j = 22
3 + j - 3 = 22 - 3
j = 19

A picture has a height that is 2 times it’s width . It is to be enlarged to an area of 128 in 2
morpeh [17]

9514 1404 393

Answer:

  8 in by 16 in

Step-by-step explanation:

In your equation, we presume that x represents the width. Solving for x, we have ...

  2x² = 128 . . . . . . given equation

  x² = 64 . . . . . . . . divide by 2

  x = √64 = 8 . . . . square root

The enlargement will be 8 inches by 16 inches.

The slope intercept form for a line is y = mx + b.
                                                                 ↑      <span>↑

m is the slope of the line or how steep it is. b is where the line runs into the y axis at one point. x and y are the values you plug in when you have a specific point you want to use (x, y).

For the first picture, you can see that the line "intercepts" or collides with the y axis at 1. Thus we know the b value.

To find the slope, you just pick 2 points on the line and plug them into a little equation (try to memorize this equation, it helps to find slope):

m = (y</span>₂ - y₁)/(x₂ - x₁)

The two points we'll use are (1, 0) and (0, 1) since x goes through both of
those points.                          ↑  ↑           ↑  ↑
                                              x₁ y₁        x₂ y<span>₂

m = (1 - 0)/(0 - 1)

m = 1 / -1

m = -1

This makes sense - since the slope is going downward, the slope is negative.

So the equation is:

y = -x + 1

____________________________________________________________

For the second problem, We  can see the line intercepts the y-axis at -5. That is our b value.

The the slope of this line is 0 since it is not going up or down, so that is our m value:

y = 0(x) - 5 = -5

The equation of the line is y = -5</span>

Use the given information and a calculator to find to the nearest tenth of a degree
Schach [20]

Answer:

111.4 degrees

Step-by-step explanation:

Let's write cos x = -0.3646.  Or, look up the symbols chart at the bottom of your page and click on Ф to obtain this character:  cos Ф = -0.3646.

If Ф is in Quadrant III, then the adjacent side is negative and the hypotenuse is positive.  

                                                         -1

Type this into your calculator:  cos     -0.3646.  Result:  1.934 (radians)

This converts to degrees as follows:

1.934 rad      180 degr

--------------- * --------------- = 111.4 degrees.  Note that this angle is in QIII.

        1              π rad
