Answer:

4(11y +22)

Step-by-step explanation:

5(9y+19.8) =45y+99

9(5y+11)=45y+99

2(22.5y+49.5)=45y+99

4(11y+22)=44y+88

you must expand the numbers to get the total

for example you multiply 5×9y and 5×19.8 in a

U-3/4=4 please help me ty

Ne4ueva [31]

To solve the equation:

$\frac{u - 3}{4} = 4 \\ \frac{u - 3}{4} \times 4 = 4 \times 4\\ u - 3 = 4 \times 4 \\ u - 3 + 3 = 16 + 3 \\ u = 16 + 3 \\ u = 19$

Therefore, the answer is u=19.

Hope it helps!

Please help me with this question

Setler [38]

Step-by-step explanation:

${ ({y}^{2} )}^{4} . \: {( {y}^{3}) }^{2}$

Since,

${ ({a}^{x} )}^{y} = {a}^{xy}$

Hence,

${y}^{2 \times 4} . {y}^{3 \times 2}$

$= {y}^{8} . {y}^{6}$

Since,

${a}^{x} . {a}^{y} = {a}^{x + y}$

Hence,

$= {y}^{8 + 6}$

$= {y}^{14} (ans)$

Choose the correct slope of the line that passes through the points (1, -3) and (3, -5).

KATRIN_1 [288]

The slope: $m=\dfrac{y_2-y_1}{x_2-x_1}$

$(1;-3)\to x_1=1;\ y_1=-3\\(3;-5)\to x_2=3;\ y_2=-5\\\\subtitute:\\\\m=\dfrac{-5-(-3)}{3-1}=\dfrac{-5+3}{2}=\dfrac{-2}{2}=-1$

Answer: m = -1
