Answer:
z=2
Step-by-step explanation:
When you subtract a negative, you are adding the number, so the question simplify into 14= z + 12, which is 2

Answer:
a = 4, b = - 5, c = 5
Step-by-step explanation:
Expand the product of factors on the left side and compare like terms on both sides.
(3x - 1)(ax + b) ← expand using FOIL
= 3ax² + 3bx - ax - b
= 3ax² + (3b - a)x - b
Equating coefficients of like terms with 12x² - 19x + c , then
3a = 12 ( divide both sides by 3 )
a = 4
3b - a = - 19
3b - 4 = - 19 ( add 4 to both sides )
3b = - 15 ( divide both sides by 3 )
b = - 5
c = - b = - ( - 5) = 5

Answer: A.</h2>
Step-by-step explanation:
<em>Victoria's recipe:</em>
<em />
<em>170g of butter = 250 g of flour</em>
<em />
<em>1 g of butter = 250 ÷ 170 = 25/17 g of flour</em>
<em />
<em />
<em>Daughter's recipe:</em>
<em />
<em>340 g of butter = 400 g of flour</em>
<em />
<em>1 g of butter = 400 ÷ 340 = 20/17 of flour</em>
<em />
<em />
<em>Compare:</em>
<em />
<em>20/17 < 25/17 </em>
<em />
<em>⇒ Daughter uses less flour in her cookies</em>
<em />
<em>⇒ the cookies are more dense</em>
<em>So therefor, the correct answer is A. They have too much butter :) </em>
<em>* </em><em>Hopefully this helps:) Mark me the brainliest:)!!!!</em>
y = 1 - 3x goes to slope -3, y-intercept at 1
x - 3 = y goes to slope 1, y-intercept at -3
y = 3x - 1 goes to slope 3, y-intercept at -1
-x + 3 = y goes to slope -1, y-intercept at 3
