<span>The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 39 are 1, 3, 13, and 39. A GCF, or greatest common factor, is the largest (greatest) number that divides two numbers. From the lists, we see that this is 3. If we factor out the 3 from both 12 and 39 essentially undoing the distributive property, we are left with the product 3 * ( 4 + 13 ).</span>
Answer:
1, -5, -14
Step-by-step explanation:
Domain is the x-axis, and range is the y axis.
So plug in the x values (domain values) to the equation.
Answer:
B
Step-by-step explanation:
A'C'
We are given the cost of the product along with the markup percentage. The markup is how the store makes a profit. To figure out the markup price, simply multiply the "cost to store" by 100% plus the markup percent.
So the markup prices per store is:
A = 162 * 1.4 = $226.80
B = 155 * 1.3 = $201.50
C = 160 * 1.25 = $200.00
Clearly, the best deal is store C. So in order to choose store A, we want to pay less than the price of Store C, $200. So if Store A cost $199.99, then we would purchase there instead of Store C.
Therefore, $226.80 - $199.99 = $26.81
If Store A offered a discount of $26.81, we would purchase from Store A.
$26.81/$226.80 = 0.1182
So we would need a discount of 11.82% from Store A.
X+y=4
2x+y=6
make first equation negative
-x-y=-4
add to first equation
2x-x+y-y=6-4
x=2
subsitute
x+y=4
2+y=4
y=2
or
x+y=4
subtract x from both sdies
y=4-x
subsitute 4-x for y in second equation
2x+4-x=6
x+4=6
x=2
