F(x)=-2x+3 how do you find x if f(x) = 11

Answers

Answer 1
Answer: since we know f(x)=11 all we need to do is substitute and solve. so
11=-2x+3 subtract 3 from both sides
8=-2x divide both sides by -2
-4=x
sub back in to check

-2(-4)+3=8+3=11 looks good

Answers

it would be less steep.. 

remember this general form y =mx + c 

where m is the slope and c is the y-axis intercept.. 

here u have changed only the slope.. the line is sloping 4 times less..

Answer:

Less steep

Write a system of equations with a solution (4,–3)

Answers

1.       So we have the system of equation. (4, -3)
let’s create another system of equation.
Let a = 4
and Let b = -3
First equation
=> Let’s pick any numbers to be used. Let’s have number 5
=> 5a + 5b
=> 5 (4) + 5 (-3)
=> 20 + (-15)
negative and positive is equals to negative
=> 20 – 15
=> 5 (this the first value of our equation, let this be the value of X)

Second
=> Pick another number, Let’s have 6
=> 6a + 6b
=> 6 (4) + 6 (-3)
=> 24 + (-18)
=> 24 – 18
=> 6 (this is the value of our second equation, let this value be Y)

Now, we have (A, B) = (4, -3) and (X, Y) = (5,6)




Answer:

A linear equation can be written in several forms. "Standard Form" is #ax+by=c# where #a#, #b# and #c# are constants (numbers).

We want to make two equations that

(i) have this form,

(ii) do not have all the same solutions (the equations are not equivalent), and

(iii) #(4, -3)# is a solution to both.

#ax+by=c#. We want #a#, #b# and #c# so that

#a(4)+b(-3)=c# (This will make (i) and (iii) true.)

Answers

Answer:

x=-4

Step-by-step explanation:

brainliest please

Answer:

x=-4, Give brainliest please

Step-by-step explanation:

Step 1: Add 8.4x to both sides.

2.1x+45.2 =  -8.4x +3.2

       +8.4x    +8.4x

10.5x+45.2=3.2

Step 2: Subtract 45.2 from both sides.

10.5x + 45.2 = 3.2

         -45.2    -45.2

10.5x=−42

Step 3: Divide both sides by 10.5.

(10.5x)/(10\n)=(-42)/(10)

x=−4

Help pls! Will give brainliest!

To determine which line among AB, BC, and CA is parallel to the line 2y - 3x = 6, we need to find the slopes of these lines and compare them to the slope of the given line.

The slope-intercept form of a line is y = mx + b, where m is the slope.

Given line: 2y - 3x = 6
To convert it into slope-intercept form, isolate y:
2y = 3x + 6
y = (3/2)x + 3

The slope of the given line is (3/2).

Now, let's find the slopes of the lines AB, BC, and CA:

1. Line AB:
Coordinates of A(-5, -12) and B(11, -4)

Slope (m) of AB = (change in y) / (change in x) = (-4 - (-12)) / (11 - (-5)) = 8 / 16 = 1/2

2. Line BC:
Coordinates of B(11, -4) and C(7, 6)

Slope (m) of BC = (change in y) / (change in x) = (6 - (-4)) / (7 - 11) = 10 / (-4) = -5/2

3. Line CA:
Coordinates of C(7, 6) and A(-5, -12)

Slope (m) of CA = (change in y) / (change in x) = (-12 - 6) / (-5 - 7) = -18 / (-12) = 3/2

Now, let's compare the slopes:

- Slope of the given line: 3/2
- Slope of AB: 1/2
- Slope of BC: -5/2
- Slope of CA: 3/2

The line that is parallel to the given line 2y - 3x = 6 is Line CA, as it has the same slope of 3/2.

Answer:

CA.

Step-by-step explanation:

To find the gradient (slope) of the line 2y - 3x = 6, we need to rewrite the equation in slope-intercept form (y = mx + b), where "m" represents the gradient. Here's how:

2y - 3x = 6

First, isolate "y" on one side of the equation:

2y = 3x + 6

Next, divide both sides by 2 to solve for "y":

y = (3/2)x + 3

Now we can see that the gradient (slope) of the line is (3/2).

Now, let's analyze the three lines AB, BC, and CA, formed by the points A(-5, -12), B(11, -4), and C(7, 6).

The gradient (slope) of the line AB can be calculated using the coordinates of points A and B:

Gradient of AB = (Change in y) / (Change in x) = (-4 - (-12)) / (11 - (-5)) = 8 / 16 = 1/2

The gradient (slope) of the line BC can be calculated using the coordinates of points B and C:

Gradient of BC = (Change in y) / (Change in x) = (6 - (-4)) / (7 - 11) = 10 / (-4) = -5/2

The gradient (slope) of the line CA can be calculated using the coordinates of points C and A:

Gradient of CA = (Change in y) / (Change in x) = (-12 - 6) / (-5 - 7) = -18 / (-12) = 3/2

Now, we compare the gradients of the lines AB, BC, and CA to the gradient of the line 2y - 3x = 6 (which is 3/2). We see that the line CA has the same gradient (3/2) as the line 2y - 3x = 6.

So, the line CA is parallel to the line 2y - 3x = 6.
