Answer:

2xz⁵/y⁴

Step-by-step explanation:

Given expression:

$\frac{16x^2yz^{13}}{8xy^5z^8}$

Simplify considering like terms:

16/8 = 2
x²/x = x
y/y⁵ = 1/y⁴
z¹³/z⁸ = z⁵

The simplified expression is:

2xz⁵/y⁴

Determine the value of r so that the line through (5, 2) and (7, r) has a slope of m= -1/2

vodka [1.7K]

Y = mx + b
slope(m) = -1/2
(5,2)...x = 5 and y = 2
sub and find b
2 = -1/2(5) + b
2 = -5/2 + b
2 + 5/2 = b
4/2 + 5/2 = b
9/2 = b

so ur equation for this line is : y = -1/2x + 9/2

y = -1/2x + 9/2......(7,r)....when x = 7
y = -1/2(7) + 9/2
y = -7/2 + 9/2
y = 2/2
y = 1

so ur missing variable is 1......ur set of points would then be (7,1) <=

X2 + 8x + 19 = 0 What is the equivilent that results from completing the square?

IrinaVladis [17]

Answer:

$(x+4)^2+3=0$

Step-by-step explanation:

Hey there!

Standard form is what this equation is in

Standard form is this: $ax^2+bx+c$

So order to complete the square, you need to take the $b$ term out of the equation, divide it by two, and then square it

In this case, the $b$ term is 8

We need to divide 8 by 2 ---> 4

Then square 4 ---> 16

So now you should add 16 to both sides

$x^2+8x+16+19=16$

Now you can simplify the LHS

$(x+4)^2 +19=16$

Now you subtract 16 from both sides

$(x+4)^2+3=0$

So this is as far as you can go since you cannot take the square root of a negative number

36-4c-3c=22 I don't understand how to solve for c

LiRa [457]

Subtract 36 from both sides making it: -4c-3c=-14
Now subtract -4c and 3c making it: -7c=-14
Now divide by -7 on both sides making it: c=2
There you go
