3s + h = $47
7s + 2h= $107
3s + h =$47
3s - 3s + h = $47 -3s
h = $47 - 3s
7s + 2($47 - 3s) = $107
7s + 94 -6s = 107
s + 94 = 107
s +94 -94 = 107- 94
s = 13
3(13) + h = $47
39 + h =$47
39 -39 + h= $47-39
h = 8
Check
7s + 2h= $107
7(13) + 2(8)= $107
91 + 16= 107
107 = 107
She earns $13 per suit sold and $8 per pair of shoes sold.
Answer:
x=0.27
Step-by-step explanation:
The given expression is
To solve this equation, we graph the functions:
and
From the graph, the two curves intersects at x=-0.24 and x=0.27.
But the domain of the logarithmic function is x>0
Therefore x=0.27

Answer:
well it uses the compound interest formula
F(x) = P_{0}(1 + \frac{r}{100})^x
so in your question
x = time in years for the initial formula
P_{0} = 293,.... r = 6% ...and...
then you need to substitute x = 4
simplify the brackets and you should get the answer.
Answer:
no it isn't linear equation
A linear equation is any equation that can be written in the form. ax+b=0. where a and b are real numbers and x is a variable. This form is sometimes called the standard form of a linear equation.
