This much, I understand from that $\bf \begin{cases}
y_1=11x-3\\
y_2=4x+19\\
-----------\\
\textit{now, whatever }y_1\ is\ y_2\ \textit{is 6 more than that}\\
y_2=y_1+6\\
4x+19=(11x-3)+6\impliedby \textit{solve for "x"}
\end{cases}$

Can anyone help me with 49 and 50 thank you

Answer:

see explanation

Step-by-step explanation:

Using the rule of exponents

$a^{m}$ × $a^{n}$ ⇔ $a^{(m+n)}$

3b × 4b³ = (3 × 4) × $b^{(1+3)}$ = 12 $b^{4}$

5x² × 8x × 5x³

= (5 × 8 × 5) × $x^{(2+1+3)}$ = 200 $x^{6}$

Given a graph for the transformation of f(x) in the format g(x) = f(x) + k, determine the k value.

enyata [817]

Answer:

k=6

Step-by-step explanation:

The parabola that opens up and passes through (-3,-3) will have equation,

$f(x) = {x}^{2} - 12$

The parabola the opens up a d passes through (-3,3) will have equation:

$g(x) = {x}^{2} - 6$

We want to determine the value of k, for which,

$g(x) = f(x) + k$

We rewrite g(x) in terms of f(x) to get:

${x}^{2} - 6 = {x}^{2} - 12 + 6$

$g(x) \to({x}^{2} - 6 )= f(x) \to ({x}^{2} - 12 )+k \to6$

Therefore;

$g(x) = f(x) + 6$

Hence k=6

Please help me find BD

Tanzania [10]

9514 1404 393

Answer:

14 units

Step-by-step explanation:

The angle bisector divides the sides proportionally, so you have ...

(x+4)/8 = (2x+1)/12

3(x +4) = 2(2x +1) . . . . . . multiply by 24

3x +12 = 4x +2 . . . . . . . . eliminate parentheses

10 = x . . . . . . . . . . . subtract (3x+2)

Then BD = x+4 = 10 +4.

The length of BD is 14 units.

<em>Additional comment</em>

The "triangle" cannot exist, as the side lengths are shown as 8, 12, and 35. The long side is too long. Nice math; bad geometry.
