Solve this in distributing -(5.3x-7y)-9.6

algol13

Answer:

$-\left(5.3x-7y\right)\left(-9.6\right)=\:50.88x-67.2y$

Step-by-step explanation:

Given the expression

$-\left(5.3x-7y\right)\times \left(-9.6\right)$

$=-\left(-9.6\right)\left(5.3x-7y\right)$

Apply distributive law

$a\left(b-c\right)=ab-ac$

$a=-\left(-9.6\right),\:b=5.3x,\:c=7y$

so the expression becomes

$=-\left(-9.6\right)\times \:5.3x-\left(-\left(-9.6\right)\right)\times \:7y$

$=-\left(-9.6\right)\times \:5.3x+7\left(-9.6\right)y$ ∵ $-\left(-a\right)=a$

$\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a,\:-\left(-a\right)=a$

$=9.6\times \:5.3x-7\times \:9.6y$

$=50.88x-7\times \:9.6y$

$=50.88x-67.2y$

Therefore,

$-\left(5.3x-7y\right)\left(-9.6\right)=\:50.88x-67.2y$

If the base price of a concert ticket ticket is $30 and the handling the change is 15% is added to the brace what is the total c

mel-nik [20]

Answer: $34.50

Step-by-step explanation:

Based on the information given in the question, since the base price of a concert ticket ticket is $30 and the handling the change is 15% is added to the brace, then the total cost of the ticket will be calculated thus:

= $30 + (15% × $30)

= $30 + (0.15 × $30)

= $30 + $4.5

= $34.5

Therefore, the total cost of the ticket is $34.50

Find the slope of the line through the pair of points. A(2, –3), P(2, 9)

Flauer [41]

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

$A(2;-3)\to x_1=2;\ y_1=-3\\P(2;\ 9)\to x_2=2;\ y_2=9\\\\subtitute:\\\\m=\dfrac{9-(-3)}{2-2}=\dfrac{12}{0}!!!$

<span>The denominator can not be <span>zero!

Conclusion: The slope is undenfined.
