Answer:

See the attached figure

Given:

-3x + 2y = 8

5x + 2y = -8

To graph the given equation, make a table between x and y for each equation

Assume x then find the value of y

as an example:

for the equation -3x + 2y = 8

Let x = 0 so, y = 8/2 = 4 and so on

Then graph the pair (x,y), connect the points to graph the line

The attached figure represents the graph of the both line and the table for each line required to graph it.

Also, the intersection between the lines.

Find all the points on the curve y = 4x^4 − 8x^2 + 16x + 7 such that the tangent line to the curve is parallel to the line 16x −

IrinaVladis [17]

Hello :
the tangent has same slope of the line 16x -y +5 = 0 because parallel.
y = 16x + 5
the slope is : 16
but : f'(x) = 16
f'(x) = 16x^3 - 16x +16
solve : 16x^3 - 16x +16 = 16
x^3 - x +1 =1
x^3 - x = 0
x(x² - 1 ) =0
x(x -1 )(x +1) =0
x=0 or x-1 =0 or x +1= 0
x=0 or x = 1 or x = -1
if : x = 0 : y = 4(0)^4 -8(0)^2+16(0) +7 =7
if : x =1 : y = 4(1)^4 -8(1)^2+16(1) +7 = 19
if : x = -1 : y = 4(-1)^4 -8(-1)^2+16(-1) +7 = -13
the points : A(0,7) , B(1 , 19) , c ( -1 , -13)

Solve for x. 5(x – 10) = 30 – 15x

klio [65]

You can start by distributing the 5 to everything in the parenthesis.
5x-50=30-15x

Then get rid of your x values from one side, I chose to subtract 5x

-50 = 30 - 20x

Then subtract 30

-80=-20x
/-20
4=x

You can check by plugging your x into the equation to make sure it's right!
