For the given equation, either 3x + 7 = 0 or x + 7 = 0

Now,

  • 3x + 7 = 0

  • 3x = -7

  • x = -7/3

or

  • x + 7 = 0

  • x = -7

So, possible values of x is : -7 and -7/3

(3x + 7)(x + 7) = 0 \\  \\  \\3x + 7 = 0 \\  \\ 3x =  - 7 \\  \\ x =  \frac{ - 7}{3} . \\  \\  \\ x + 7 = 0 \\  \\ x =  - 7.

The table below shows selected points from a function.
FrozenT [24]

Answer:

<em>True </em>

Step-by-step explanation:

<em>Rate Of Change Of Functions </em>

Given a function y=f(x), the rate of change of f can be computed as the slope of the tangent line in a specific point (by using derivatives), or an approximation by computing the slope of a secant line between two points (a,b) (c,d) that belong to the function. The slope can be calculated with the formula

\displaystyle m=\frac{d-b}{c-a}

If this value is calculated with any pair of points and it always results in the same, then the function is linear. If they are different, the function is non-linear.

Let's take the first two points from the table (1,1)(2,4)

\displaystyle m=\frac{4-1}{2-1}=3

Now, we use the second and the third point (2,4) (3,9)

\displaystyle m=\frac{9-4}{3-2}=5

This difference in values of the slope is enough to state the function is non-linear

Answer:

  B. Draw a diagram.

Step-by-step explanation:

Most construction starts with a diagram.

_____

<em>Additional comment</em>

You may actually start by finding a pattern you like, then figuring the material required to construct the pattern, then working backward to determine the dimensions you need to use to stay within your material budget. You will probably draw a diagram at many points in the planning process.

Two numbers A and B are such that the sum of 5% of A and 4% of B is two-third of the sum of 6% of A and 8% of B. Find the ratio
adoni [48]

Answer:

a : b = 4 : 3

Step-by-step explanation:

(mark as brainlist answer)

According to the given condition is the question :

Two numbers a and b are such that the sum of 5% of a and 4% of b is two-third of the sum of 6% of a and 8% of b

⇒ (5% of a) + (4% of b) = (2/3) × [(6% of a) + (8% of b)

⇒ 0.05a + 0.04b = 2/3 × (0.06a + 0.08b)

⇒ 0.15a + 0.12b = 0.12a + 0.16b

⇒ 0.03a = 0.04b

⇒ a/b = 4/3

⇒ a : b = 4 : 3
