Answer:
Step-by-step explanation:
x/4-y/2=8, x-2y=32, x=32+2y
x/2+3y/4=-5, 2x+3y=-20, x=(-20-3y)/2
32+2y=(-20-3y)/2
64+4y=-20-3y
7y=-84
y=-12, since x=32+2y
x=32+2(-12), x=32-24=8
So the solution is the point (8, -12)
Answer:
its (8, -12)

If a/b=b/c,then what is b²?
Given:
The equation is
[tex]\dfrac{a}{b}=\dfrac{b}{c}[/tex]
To find:
The value of [tex]b^2[/tex].
Solution:
We have,
[tex]\dfrac{a}{b}=\dfrac{b}{c}[/tex]
On cross multiplication, we get
[tex]a\times c=b\times b[/tex]
[tex]ac=b^2[/tex]
[tex]b^2=ac[/tex]
Therefore, the value of [tex]b^2[/tex] is [tex]ac[/tex].

Marilyn collects old dolls. She purchases a doll for $450. Research shows this doll's value will increase by 2.5% each year. Write an equation that determines the value, V, of the doll t after purchase.
Answer:
V = 450 + 0.025t
Step-by-step explanation:
What we know is that Marilyn purchases a doll for $450 dollars, and the value will increase by 2.5% each year. Now that we know this, this means we need an addition equation. We know 450 is being add to the 2.5% increase so the equation is V = 450 + 0.025t. (I put 2.5% as a decimal (0.025))
The equation that determines the value, V, of the doll (t) after purchase is [tex]V = 450 ({1.025}{} )^{t}[/tex]
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
What is compound interest?Compound interest is an interest accumulated on the principal and interest together over a given time period. The compound interest is calculated, after calculating the total amount over a period of time, based on the rate of interest, and the initial principal.
Formula of Compound Interest
[tex]A = P (1+\frac{r}{100} )^{n}[/tex]
Where,
A = Final amount
P = Initial principal
r = Rate per annum
n = Time in years
According to the question
Marilyn purchases a doll for = $450
i.e, Initial Principal (P) = $450
Doll's value will increase each year by = 2.5%
i.e, Rate per annum = 2.5%
Value (V) of the doll after purchase = Final amount (A)
(t) = Time in years (n)
Now, Formula of compound interest
[tex]A = P (1+\frac{r}{100} )^{n}[/tex]
Substituting the values in formula
[tex]V = 450 (1+\frac{2.5}{100} )^{t}[/tex]
[tex]V = 450 (1+{0.025}{} )^{t}[/tex]
[tex]V = 450 ({1.025}{} )^{t}[/tex].
Hence, equation that determines the value, V, of the doll (t) after purchase is [tex]V = 450 ({1.025}{} )^{t}[/tex]
