Answer:

y = - 12x - 42

Step-by-step explanation:

Given

y - 6 = - 12(x + 4) ← distribute parenthesis

y - 6 = - 12x - 48 ( add 6 to both sides )

y = - 12x - 42

Kate has a coin collection. She keeps 7 of the coins in a box witch is only 5%of her entire collection. What is the total number

yarga [219]

Answer:

140 coins total

Step-by-step explanation:

Straightforward, this reads "7 is 5% of how many?". Algebraically, the word "is" means an equals sign, and the word "of" means you multiply. Of course, the 5% needs to be in decimal form. Taking the sentence above, algebraically it is: 7 = .05x. Divide by .05 on both sides to get x = 140

For each of the figures, write Absolute Value in the form |x-c|=d, where c and d are some numbers, to satisfy the solution set.

Vadim26 [7]

Answer:

$(a)$ $|0 - 8| = 8$

$(b)$ $|-4 - 6| = 10$

Step-by-step explanation:

Given

Attached number lines

Required

Express as: $|x - c| =d$

The two points on the number line represent x and c (in no particular) respectively.

Solving (a):

Let:

$x = 0$

$c = 8$

So:

$|x - c| =d$

$d =|0 - 8|$

Solve the expression in the absolute bracket

$d =|- 8|$

Remove absolute bracket

$d = 8$

So: the expression is;

$|0 - 8| = 8$

Solving (b):

Let:

$x = -4$

$c = 6$

So:

$|x - c| =d$

$d = |-4-6|$

Solve the expression in the absolute bracket

$d = |-10|$

Remove absolute bracket

$d = 10$

So: the expression is;

$|-4 - 6| = 10$

Hi can someone please answer this question? <br><br> Thank you :)

Archy [21]

Answer:

$\frac{7}{8}$

Step-by-step explanation:

Remember that slope, or in this case pitch, is equal to rise divided by run. In other words:

$m=\frac{rise}{run}$

where m is the slope.

From looking at the image, we can see that the rise 21 feet and the run is 24 feet. By plugging this information into the equation, we get:

$m=\frac{21}{24}=\frac{7}{8}$

So the slope, or pitch, of the roof id 7/8.

I hope you find my answer and explanation to be helpful. Happy studying.

3x - 7y = 11<br> What is y equal to?

lara31 [8.8K]

Answer:

3.666666667

Step-by-step explanation:

Simplifying

3x + -7y = 11

Solving

3x + -7y = 11

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '7y' to each side of the equation.

3x + -7y + 7y = 11 + 7y

Combine like terms: -7y + 7y = 0

3x + 0 = 11 + 7y

3x = 11 + 7y

Divide each side by '3'.

x = 3.666666667 + 2.333333333y
