So all you have to do to solve these problems is substitute the y coordinate and the x coordinate into the equation.

So question 1 would be true because when you substitute the numbers in it equals the y value.

Question 2 is (4, -7)

Question 3 is False

Question 4 is true

Question 5 is true

See if you can do the rest!

6x - 42 = 10x + 40

6x - 82 = 10x

-82 = 4x

-82 / 4 = -20.5

x = -20.5

6(-20.5 - 7) = -165

10(-20.5 + 4) = -165

6x - 82 = 10x

-82 = 4x

-82 / 4 = -20.5

x = -20.5

6(-20.5 - 7) = -165

10(-20.5 + 4) = -165

In this problem we will find out the value of the function composition. There are two ways to do it.

**First way**

**Step-1: compose (f o g)(x) = f(g(x))**

Here g(x) as input into f(x). In other words, first we apply g(x), then apply f(x) to that result:

And we get,

**Step-2: calculate the value of f(g(2))**

After getting f(g(x)) we proceed by calculating the value f (g(2)).

**And we obtain the final result:**

**Second way**

**Step-1: count g(2) initially**

And we get,

**Step-2: calculate the value of f(g(2))**

Here the value of g(2), i.e. -15, as input into f(x).

**And we obtain the final result:**

- Let f(x) = x-3 and g(x ) = x^2 find f(g(4)) brainly.com/question/1052893
- Which expression is equal to f(x) · g(x)? brainly.com/question/9622736

**Answer:**

Given: The transformation g(x) =6f(x) ......[1]

To find the corresponding values of g(x) for the given transformation.

**At x = -7, f(x) = 8**

then,

By substituting the value of f(x) = 8 in [1] we have

Similarly,

**For x= -3 , f(x) = 3, **then

By substituting the value of f(x) = 3 in [1] we have

**For x= 0, f(x) = -1 ,** then

By substituting the value of f(x) = -1 in [1] we have

**For x= 2, f(x) = 7,** then

By substituting the value of f(x) = 7 in [1] we have

**For x= 10, f(x) = 5,** then

By substituting the value of f(x) = 5 in [1] we have

Therefore ; we have the corresponding values of g(x) as shown below;

QUESTION POSTED AT 19/08/2019 - 01:00 AM

**Answer: The answers are given below.**

**Step-by-step explanation: **The calculations are as follows:

**(1). The mid-point of a line segment divides it in the ratio m : n = 1 : 1.**

So, **the co-ordinates of the mid-point of the segment joining the points (a, b) and (j, k) are**

**So, the co-ordinates of the mid-point are**

**Thus, (d) is the correct option.**

**(2). The co-ordinates of the points 'T' and 'J' are (0, 4) and (0, 2) respectively.**

Let,** (a, b) **be the co-ordinates of the point** 'H'.**

**Since 'T' is the mid-point of the line segment JH, so we have**

**So, the co-ordinates of 'H' are (0, 6).**

**Thus, (a) is the correct option.**

**(3). The given point is (-4, 3).**

Since 'x' co-ordinate is **negative** and 'y' co-ordinate is **positive, so the given point lies in Quadrant II.**

Thus, **(b) is the correct option.**

**(4). The given point is (6, 0).**

Here, 'y' co-ordinate is** zero, so the point lies on the X-axis.**

Thus,** (a) is the correct option.**

**(5). The slope-intercept form of a line is**

**y = mx + c, where, 'm' is the slope and 'c' is the y-intercept.**

If slope, m = 0, **then the equation becomes**

y = 0 × m + c

**⇒ y = c, which is the equation of a line parallel to X-axis.**

**Thus, option (a) is correct.**

**(7). The point (a, 3) lies on the graph of the equation 5x + y = 8, so we have**

**Thus, (a) is the correct option.**

**(8). Given that the equation of a circle is**

We know that **the equation of a circle with centre (g, h) and radius 'r' units is given by**

Comparing equation (i) with the above general equation, **we get**

**(g, h) = (-5, 7).**

**So, the centre point is (-5, 7).**

**Thus, option (b) is correct.**

**(9). Given that the equation of a circle is**

We know that **the equation of a circle with centre (g, h) and radius 'r' units is given by**

Comparing equation (ii) with the general equation, we get

r² = 36 ⇒** r = 6 units.**

So, the radius is **6 units.**

Thus, **option (a) is correct**.

**(10). Given that the equation of a circle is**

We know that** the equation of a circle with centre (g, h) and radius 'r' units is given by**

**Comparing equation (iii) with the above general equation, we get**

**(g, h) = (2, 6).**

**So, the centre point is (-5, 7). Hence, the given statement is TRUE.**

All the questions are** ANSWERED.**

The system of equations that has no solution are the equations that has the same slope which means they are parallel and do not intersect with each other at any point. From the choices, the correct answer is option D.

7y = 5x − 10

y = (5/7) - 10/7

**slope = 5/7**

10x − 14y = 8

-14y = -10x + 8

y = (5/7) - 4/7

**slope = 5/7**

7y = 5x − 10

y = (5/7) - 10/7

10x − 14y = 8
