Answer 2

Answer:

m∡B = 37°

Step-by-step explanation:

since this is a right triangle you can use the trigonometric ratios of

sin, cos, or tan

in this problem, we know opp/adj so can use tangent

tan(∠B) = 3/4

tan^-1(3/4) = 36.8°

Answers

Answer:

infinite solutions

Step-by-step explanation:

At first, we try to isolate the x, but adding 4 to -4 on both sides. Both sides have a -4 so it cancels out on both sides of the equation. Similarly, both sides also have a positve 6x, so when we subtract 6x from 6x we get 0. After simplification, we get x = x; x can be any number [ex. 1=1, 2=2, 3=3,etc.], therefore any number can fit into this equation

6x - 4 = -4 + 6x

6x - 4 + 4 = -4 + 4 +6x

6x = 6x

x = x

Answers

Answer:

The true statements are;

A. The point (0, -3) is on the line

C. The point (-6, -6) is a point on the line

Step-by-step explanation:

The question relates to the finding of the equation of a straight line graph

The x-intercept of the graph is (6, 0) and the graph passes through the point (2, -2)

Therefore, the slope of the graph is m = (-2 - 0)/(2 - 6) = 0.5

The equation of the graph in point and slope form is given as follows;

y - 0 = 0.5 × (x - 6)

∴ y = 0.5·x - 3

Therefore, the equation of the graph in slope and intercept form, y = m·x + c is also y = 0.5·x - 3

A. The y-intercept of the graph is (0, -3), therefore, the point (0, -3) is on the line

B. The equation of the graph, y = 0.5·x - 3, can be written as follows;

8·y = 8 ×0.5·x - 8 × 3 = 4·x - 24

∴ 8·y - 4·x = -24

C. When y = -6, 'x' is given as follows;

y = 0.5·x - 3

-6 = 0.5·x - 3

0.5·x = -6 + 3 = -3

x = -3/0.5 = -6

x = -6

Therefore, when y = -6, x = -6, and (-6, -6) is a point on the line

D. When x = 0, 'y', is given as follows;

y = 0.5·x - 3

When x = 0, y = 0.5 × (0) - 3 = -3

Therefore the point (0, -3) is on the line and the point (0, -4) is not on the line

E. The point (-6, 0) represent an x-intercept of a line graph, however the x-intercept on the given line is (6, 0) and when y = 0 on the line, x = 6

Therefore, the point (-6, 0) is not on the line

F. The equation of the graph is 8·y - 4·x = -24, therefore, - 4·x + 8·y = 24 does not represent the equation of the graph

Answers

The equation y = x2 – 4 + y + 2 = 0 can be solved by completing the square.

What is equation?

An equation is a mathematical statement that to express our equal. Is consist of two expression separated by an equal sign and can contain numbers, variables and operators. Equation get be used to solve problems make prediction and describe relationship between different quantities. Equation can be can also be used to represent physical laws and other phenomena.

First, subtract y from both sides of the equation to get x2 - 4 + 2 = y. Then, subtract 2 from both sides of the equation to get x2 - 6 = y. Finally, add 9/4 to both sides of the equation to get (x - 3/2)2 = 9/4 + y.

This equation can be solved by taking the square root of both sides to get x - 3/2 = ±√(9/4 + y). Finally, add 3/2 to both sides of the equation to get x = 3/2 ±√(9/4 + y).

Which function represents exponential growth?

b. f(x) = x3
c. f(x) = x + 3
d. f(x) = 3x
FIRST PERSON TO ANSWER IS THE BRAINLIEST!!!!
PLEASE GIVE EXPLANATION OF HOW!!

Answers

Answer:

Either A or D, but the answer is [tex]f(x) = 3^x[/tex].

Step-by-step explanation:

We can check for exponential growth by checking for an [tex]x[/tex] in the exponent of a constant value in the function, which is this case for [tex]f(x) = 3^x[/tex].

f(x) = x + 3 function represents exponential growth. So the correct option is option is c.

An exponential function is a arithmetic function in the form f (x) = ax, where “x” is a variable and “a” is a constant which is know the base of the function and it will be greater than 0.

An exponential function is explain by the formula f(x) = ax, where the input variable x take place as an exponent.

The exponential curve turn on the exponential function and it depends on the value of the x.

The exponential function is an main arithmetic function which is of the form

f(x) = ax

Exponential Growth

In Exponential Growth, the quantity grow very slowly at first, and then quickly. The rate of change growth over time. The rate of growth becomes faster as time passes. The quick growth is meant to be an “exponential increase”. The formula to explain the exponential growth is:

y = a ( 1+ r )x

Where r is the growth percentage.

Therefore, f(x) = x + 3 is a function represents exponential growth.
