Where the two lines intersect is ur solution. So ur system of equations has exactly 1 solution

Simple...

you have: 3x+2y=6 and -4x+5y=15

re-write the equations-->>>

3x+2y=6 into-->>y= $-\frac{3}{2} x+3$

and

-4x+5y=15 into-->> $y= \frac{4}{5} x+3$

Set them equal to each other to solve for x-->>

$- \frac{3}{2} x+3= \frac{4}{5} x+3$

x=0

Now plug in x...to solve for y...

$- \frac{3}{2} (0)+3= \frac{4}{5} (0)+3

$

3=3

(0,3)

Thus, your answer, A.

Answer:

$-\frac{3\sqrt[3]{t} }{2}$

Step-by-step explanation:

1: Write g(t) as y, resulting in $y=-\frac{8}{27}t^3$

2: Interchange the variables y and t, resulting in $t=-\frac{8}{27}y^3$

3: Multiply both sides by 27, resulting in $27t=-8y^3$

4: Divide both sides by -8, resulting in $-\frac{27t}{8}=y^3$

5: Find the cube root of both sides, resulting in $\sqrt[3]{-\frac{27t}{8} }=y$

6: Apply a radical rule, resulting in $-\sqrt[3]{\frac{27t}{8} } =y$

7: Apply another radical rule, resulting in $-\frac{\sqrt[3]{27t} }{\sqrt[3]{8} } =y$

8: Simplify the denominator, resulting in $-\frac{\sqrt[3]{27t} }{2} =y$

9: Apply yet another radical rule, resulting in $-\frac{\sqrt[3]{27}\sqrt[3]{t} }{2} =y$

10: Simplify $\sqrt[3]{27}$ , resulting in $-\frac{3\sqrt[3]{t} }{2} =y$

If I have a floor that is 100 3/4 feet by 75 1/2 what is the area

Vlad [161]

The area, assuming is a rectangular floor, is their product.

so simply convert the mixed to improper and get their product.

$\bf \stackrel{mixed}{100\frac{3}{4}}\implies \cfrac{100\cdot 4+3}{4}\implies \stackrel{improper}{\cfrac{403}{4}}
\\\\\\
\stackrel{mixed}{75\frac{1}{2}}\implies \cfrac{75\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{151}{2}}\\\\
-------------------------------\\\\
\cfrac{403}{4}\cdot \cfrac{151}{2}\implies \cfrac{403\cdot 151}{4\cdot 2}\implies \cfrac{60853}{8}\implies 7606\frac{5}{8}~ft^2$
