Step-by-step explanation:
the question doesn't make sense and you need to rephrase the question.
-14x + 15y = 15
-14x + 14x + 15y = 14x + 15
15y = 14x + 15
15 15
y = ¹⁴/₁₅x + 1
-21x - 20y = -10
-21x - 20(¹⁴/₁₅x + 1) = -10
-21x - 20(¹⁴/₁₅x) - 20(1) = -10
-21x - 18²/₃x - 20 = -10
-39²/₃x - 20 = -10
+ 20 + 20
-39²/₃x = 10
-39²/₃ -39²/₃
x = ⁻³⁰/₁₁₉
y = ¹⁴/₁₅x + 1
y = ¹⁴/₁₅(⁻³⁰/₁₁₉) + 1
y = ⁻²⁸/₁₁₉ + 1
y = ⁹¹/₁₁₉
(x, y) = (⁻³⁰/₁₁₉, ⁹¹/₁₁₉)
Answer:
$15
Step-by-step explanation:
Set up a proportion where x is the clearance price of the $40 shirt:
= 
Cross multiply and solve for x:
32x = 480
x = 15
So, the clearance price is $15
Answer:
continuous.
Step-by-step explanation:
Given function is
.
and value of a = 7.
Now we need to find if the given function
is continuous or not.
By definition of continuity, we know that a function is continuous at a given point if both left and right hand limits are equal.
Left Hand Limit = LHL

Right Hand Limit = RHL

Since both limits are equal at a=7 so we can say that given function is continuous at a=7
Answer:
I believe the scale factor is 2.
