Answer:

The answer is 16.

Step-by-step explanation:

Negatives can be tricky, but once you get the hang of it, it will be much easier! The rule to remember here is:

"Anything 'minus a negative' just means plus, because the negatives cancel each other out."

a. For example, 4 -(-1) is the same thing as 4+1, which equals 5.

b. In this problem, 12-(-4) is the same thing as 12+4, which equals 16.

I hope this helps! Feel free to give me Brainliest if you feel this helped. :)

Draw the image of ABC under the translation (x, y) + (x,y+3).

denis-greek [22]

Answer:

The draw of the image A'B'C' in the attached figure

Step-by-step explanation:

we know that

The rule of the translation is

(x,y) -----> (x,y+3)

That means ----> The translation is 3 units up

we have the coordinates of triangle ABC

Looking at the graph

$A(-4,-3),B(0,0),C(-6,2)$

Applying the rule of translation at triangle ABC

A(-4,-3) -----> A'(-4,-3+3)

A(-4,-3) -----> A'(-4,0)

B(0,0) -----> B'(0,0+3)

B(0,0) -----> B'(0,3)

C(-6,2) -----> C'(-6,2+3)

C(-6,2) -----> C'(-6,5)

What is the equation of the line that is perpendicular to the given line and passes through the point (5, 3) ?

Lisa [10]

For this case we have that by definition, the equation of the line in the slope-intersection form is given by:

$y = mx + b$

Where:

m: It's the slope

b: It is the cut-off point with the y axis

According to the figure, the line goes through the following points:

$(x_ {1}, y_ {1}) :( 8, -10)\\(x_ {2}, y_ {2}): (- 8,10)$

We found the slope:

$m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {10 - (- 10)} {- 8-8} = \frac {10 + 10 } {- 16} = \frac {20} {- 16} = - \frac {5} {4}$

By definition, if two lines are perpendicular then the product of their slopes is -1:

$m * - \frac {5} {4} = - 1\\m = \frac {-1} {- \frac {5} {4}}\\m = \frac {4} {5}$

Thus, the equation is of the form:

$y = \frac {4} {5} x + b$

If the line goes through $(x, y) :( 5,3)$ we have:

$3 = \frac {4} {5} (5) + b\\3 = 4 + b\\3-4 = b\\-1 = b$

Finally, the equation is:

$y = \frac {4} {5} x-1$

Algebraically manipulating we have:

$y + 1 = \frac {4} {5} x\\5y + 5 = 4x\\4x-5y = 5$

Option A

Step-by-step explanation:

The multiplier of value for the first year was (1 +38%) = 1.38.

The multiplier of value for the second year was (1 -12%) = 0.88.

Then the multiplier of value for the two years was ...

1.38×0.88 = 1.2144

The value of the stock after 2 years was ...

1.2144xx

(C) Victoria has six sevenths of a pizza. She ate one fourth of it for dinner. How much pizza did Victoria eat for dinner?

Step-by-step explanation:

One clue is "of" in the story and which matches "times" in the equation sentence. The question is is about multiplication.

Words such as "more" "and" & "total" are usually clues that the question is about addition. "Give" "take" "difference" & "have/are left" are clues that there is subtraction in the process. (Please give brainliest!!)
