Answer:

7. x = 4

8. x = 10

Step-by-step explanation:

7. The angles are equal to each other so you can do

40 = 12x - 8

48 = 12x

4 = x

8. The angles add up to be 180 degrees so you can combine them and set them equal to 180

6x + 12x = 180

18x = 180

x = 10

Answer:

Step-by-step explanation:

For angle C,

cos(∠C) = \frac{\text{Adjacent side}}{\text{Hypotenuse}} = 0.97

sin(∠C) = \frac{\text{Opposite side}}{\text{Hypotenuse}} = 0.26

tan(∠C) = \frac{\text{Adjacent side}}{\text{Adjacent side}} = 0.27

Therefore, from the triangle ABC,

cos(∠A) = cos(90° - ∠C)

             = sin(∠C)

             = 0.26

sin(∠A) = sin(90 - ∠A)

            = cos(∠A)

            = 0.97

tan(∠A) = \frac{\text{sinA}}{\text{cosA}}=\frac{0.97}{0.26}

            = 3.73

Angle        \frac{\text{Adjacent side}}{\text{Hypotenuse}}                 \frac{\text{Opposite side}}{\text{Hypotenuse}}                    \frac{\text{Opposite side}}{\text{Adjacent side}}

  A                    0.26                       0.97                             3.73

How to graph y=2^x+3
Mashcka [7]

Answer:

  see below

Step-by-step explanation:

It is usually convenient to choose small exponents when graphing an exponential function. You can get a reasonable idea of the shape of the curve using x-values with a magnitude of 3 or less.

The exponential term 2^x has a horizontal asymptote of y=0 for large negative values of x. Adding 3 to that term shifts the horizontal asymptote up to y=3. Of course, everything else is shifted up the same amount.

You know that ...

  2^-1 = 1/2

  2^0 = 1

  2^1 = 2

  2^2 = 4

Adding 3 to these values will give you points on the graph for x=-1 to 2.

The difference between two integers is at least 14. The smaller integer
egoroff_w [7]

The difference between two integers is at least 14. The smaller integer  is 2. What is the larger integer?

<h3><u>Answer:</u></h3>

The largest integer is 16

<h3><u>Solution:</u></h3>

Given that difference between two integers is at least 14

The smaller integer  is 2

To find: largest integer

Let the smallest integer be "y" and largest integer be "x"

smallest integer = x = 2

difference between two integers is at least 14

So, y - 2 \geq 14

y \geq 14 + 2

y \geq 16

Thus the largest integer is 16

Yes, because if you find the common denominator and rewrite these fractions it would come out as 14/30 (7/15), and 15/30 (1/2)
