Y = (15-2x)^2(x+3) Can you guys help me with this one? All I know is the I can use the zero product Property on the x-intercepts

1 answer:

$\bf y = x(2x+5)(2x-7)\impliedby \textit{setting y = 0}
\\\\\\
0=x(2x+5)(2x-7)\implies 
\begin{cases}
0=x\\
----------\\
0=2x+5\\
-5=2x\\
\cfrac{-5}{2}=x\\
----------\\
0=2x-7\\
7=2x\\
\cfrac{7}{2}=x
\end{cases}$

2^2/5+ 3^1/10 HELP ASAP

gizmo_the_mogwai [7]

Answer:

$\sqrt[5]{4}$ + $\sqrt[10]{3}$

Step-by-step explanation:

We sure can write 2^2/5+ 3^1/10 as $2^{\frac{2}{5} } + 3^{\frac{1}{10} }$

// use the $a^{\frac{m}{n} } =\sqrt[n]{a^{m} }$ to transform the expression

Convert $2^{\frac{2}{5} }$ to $\sqrt[5]{2^{2} }$ = $\sqrt[5]{4}$ (here a = 2, n = 5, m = 2)

Then convert $3^{\frac{1}{10} }$ to $\sqrt[10]{3^{1} }$ = $\sqrt[10]{3}$ (here a = 3, n = 10, m = 1)

Now we get $2^{\frac{2}{5} } + 3^{\frac{1}{10} }$ = $\sqrt[5]{4}$ + $\sqrt[10]{3}$ . This is the simplified form, which is the answer.

Consider the following sets.

Andrews [41]

A = {x ≥ 3}, B = {x ≤ 1}

So A∪B = {x ≥ 3 or x ≤ 1}

So for x ⊆(1,3), A∪B = ∅

Apparently, (1,3) covers the first option, a will be the answer

CAN YOU PLS HELP MEEEE

laiz [17]

Answer:

10x - 2y

Step-by-step explanation:

simplify the expression.

8x–2y + x + x

combine numbers that have the same variables

8x + x + x

*those x have 1 coefficient each.

it will be 8x+1x+1x = 10x then –2y

10x–2y.

Hope it helps :)
