A= -2.1
So, (-3.7) - (-1.6) = -2.1)
I hope this helped!

Hi there!

All you need to do to solve for a is add 1.6 to both sides of the equation.

It will look like this:
a - 1.6 + 1.6 = -3.7 + 1.6

After this you will see that a = -2.1.

Hope this helps!
When in doubt just replace a with -2.1 and see if you still get -3.7. :)

Answer:

The coordinates of point P are (1, -1)

Step-by-step explanation:

If the point (x, y) reflected about the x-axis, then its image is (x, -y)

To find the image of a point reflected about the x-axis change the sign of its y-coordinate

The rule is R x-axis → (x, -y)

If the point (x, y) reflected about the y-axis, then its image is (-x, y)

To find the image of a point reflected about the y-axis change the sign of its x-coordinate

The rule is R y-axis → (-x, y)

→ Assume that the coordinates of point P are (x, y)

∵ The coordinates of point P are (x, y)

∵ The rule of the reflection is R y-axis (P)

∴ Its image = (-x, y)

∵ The image = (-1, -1)

→ Equate the two images

∴ (-x, y) = (-1, -1)

∴ -x = -1

→ Divide both sides by -1

∴ x = 1

∵ y = -1

∴ The coordinates of point P are (1, -1)

In class, Julie was asked to create a scenario for the linear function shown. She came up with the following: .Joe planned a hik

Law Incorporation [45]

Answer:

1. Julie’s scenario doesn't match the linear function graphed, because the graphed function is f(x)=-3x+12 and must be f(x)=-5x+12

2. She has counted the slope of the line incorrect.

3. She can write f(x)=-5x+12 and draw the line with the x-intercept will be at (2.4,0) and y-intercpt ar (0,12).

Step-by-step explanation:

If Joe parked 12 miles away from the cabin and after one hour, he was still 7 miles from the cabin, then he had walked 12 - 7 = 5 miles per hour.

The initial positon of Joe is at point (0,12) (after 0 hours passed, Joe was 12 miles from the cabin). The line must pas through the point (1,7) ( after one hour, he was still 7 miles from the cabin ).

Find the slope:

$\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{7-12}{1-0}=-5$

So, the slope of the linear function should be -5 (not -3).

Then the equation of the function is

$f(x)=-5x+12$

1. Julie’s scenario doesn't match the linear function graphed, because the graphed function is f(x)=-3x+12 and must be f(x)=-5x+12

2. She has counted the slope of the line incorrect.

3. She can write f(x)=-5x+12 and draw the line with the x-intercept will be at (2.4,0) and y-intercpt ar (0,12).

The sum of 4 times a number and -3 added to 9 times the number

Phoenix [80]

Answer:

The sum of 4 times a number and -3 added to 9 times the number is:

4x + (-3 + 9x)

Step-by-step explanation:

Determine what each of the words means

"the sum of" - you are going to be adding the following two numbers.

"4 times a number" - Let x be the number, so, 4x is the first number.

"and -3 added to" - again, it's going to be addition of this number and the following number.

"9 times the number" - let x be the number, so, 9x is the second number in the second addition.

Now that we know what it all means, put it together:

4x + (-3 + 9x)

I really hope this helps you =)
