The slope is -1/2. I know this because slope intercept of a line is y = mx + b. In the equation, y = -1/2 + 1/4, the slope is -1/2 and the y intercept is 1/4.

m stands for slope
b stands for y intercept

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,

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

The mean if 5 numbers is 19 what is the sum of the number?

Dahasolnce [82]

Answer:

Step-by-step explanation:

Use the mean formula: mean = sum of elements / number of elements

Plug in the mean and number of elements, then solve for the sum of the numbers:

mean = sum of elements / number of elements

19 = sum of elements / 5

95 = sum of elements

So, the sum of the numbers is 95.

(2^8 ⋅ 3^−5 ⋅ 6^0)^−2 ⋅ 3 to the power of negative 2 over 2 to the power of 3, whole to the power of 4 ⋅ 2^28 (5 points) Write y

mihalych1998 [28]

Start by looking at simplifying the smaller problems

anything to the power zero is 1 $6^0 = 1$

next apply the power of a power rule... multiply the powers

$(2^8\times 3^{-5} \times 1 )^{-2} = 2^{8\times -2}\times 3^{-5 \times -2}$

which becomes

$2^{-16}\times 3^{10}$
