Answer:

No, because it fails the vertical line test ⇒ B

Step-by-step explanation:

To check if the graph represents a function or not, use the vertical line test

Vertical line test: Draw a vertical line to cuts the graph in different positions,

In the given figure

→ Draw vertical line passes through points 2, 6, 7 to cuts the graph

∵ The vertical line at x = 2 cuts the graph at two points

∵ The vertical line at x = 6 cuts the graph at two points

∵ The vertical line at x = 7 cuts the graph at one point

→ That means the vertical line cuts the graph at more than 1 point

   in some positions

∴ The graph does not represent a function because it fails the vertical

   line test

Answer:

It has 2 constants, 1 coefficient, and 1 variable.

The given linear equation 5x + 6 = 26 has 2 constants, 1 coefficient, and 1 variable.

A quantity that may assume any one of a set of values.

A value or number that never changes in expression

A numerical or constant quantity placed before and multiplying the variable in an algebraic expression.

Given equation is 5x + 6 = 26

variables is "x" i.e. 1

constants are 6, 26 i.e. 2

coefficient is 5 i.e. 1

Answer:

Assuming the covered digits are _

The sum is 826.

243 + 1_7 + _26 = 826

The objective is to determine the sum of the two unknown digits

So; we need to think about what number can we add put in 1_7 to determine the covered digit in  _26

From ; 1_7 , we have the choice to pick from 0 - 9

Assuming the covered digit is 0; let's check if we are right

So; 243 + 107  +  _26 = 826

350 +   _26 = 826

_26 = 826 - 350

_26 = 476

So; the covered digit is in the position of 4 , but it doesn't tally together

i.e 426 is not the same as 476, which makes our assumption to be wrong.

Let consider the covered digit to be 5 for example.

So; 243 + 157  +  _26 = 826

400 +   _26 = 826

_26 = 826 - 400

_26 =  426

The covered digit is in the position of 4

SO;

426 = 426

Here , our assumption is right.

As such , the covered digits are 5 and 4

The sum of the two  covered digits are = 5 + 4 = 9

Answer:

x = 3

y = 4

Step-by-step explanation:

3x -4y = -7

4x + 3y = 24

write the first equation in terms of y

3x - 4y = -7

3x + 7 = 4y

3x/4 + 7/4 = y

now substitute that into the second equation

4x + 3y = 24

4x + 3(3x/4 + 7/4) = 24

4x + 2.25x + 5.25 = 24

6.25x + 5.25 = 24

6.25x = 24 - 5.25

6.25x = 18.75

x = 18.75/6.25

x = 3

last step, substitute x for 3 in the equation.

y = 3x/4 + 7/4

y = 3*3/4 + 7/4

y = 9/4 + 7/4

y = 4

Using graph, the value of g(x) = 8 and the y- intercept at the point (0,-1).

A graph is a "mathematical representation of a network and it describes relationship between lines and points".

According to the question,

f(x) = [tex]10^x[/tex]

g(x) = -4f(x) +12

g(x) = -4 (10ˣ) +12

The graph intersect at y-axis then x-coordinate should be zero.

Let take any two points on y-axis (0, 1) and substitute g(0) = -4 (10⁰) + 12

= 8

Hence, the value of g(x) = 8 and the y- intercept at the point (0,-1).
