Find the x- intercept and y- intercept of a straight line 6x+5y=30

EleoNora [17]

Answer:

x-intercept = 30/6 = 5

y-intercept = 30/5 = 6/1 = 6.00000

Step-by-step explanation:

calculate the Y-intercept:

Notice that when x = 0 the value of y is 6/1 so this line "cuts" the y axis at y=6.00000

y-intercept = 30/5 = 6/1 = 6.00000

Calculate the X-Intercept :

When y = 0 the value of x is 5/1 Our line therefore "cuts" the x axis at x= 5.00000

x-intercept = 30/6 = 5

Given f(x) = x^3 + kx + 2, and x + 1 is a factor of f(x), then what is the value of k?

Aleks [24]

Answer:

k = 1

Step-by-step explanation:

Given that,

$f(x) = x^3 +kx + 2$

If (x+1) is a factor of (x), we need to find the value of k.

Using remainder theorem to find it.

Put (x+1) = 0

x = -1

Put x = -1 in equation below.

$x^3 + kx + 2=0\\\\(-1)^3+k(-1)+2=0\\\\-1-k+2=0\\\\1-k=0\\\\k=1$

So, the value of k is 1.

Which equation of a line contains the points (-10,15) and (8, -3) and is parallel to y +4= -(x - 1)?

JulijaS [17]

Answer:

y= -x+5

Step-by-step explanation:

The slope of the two parallel lines is equal

so, the slope of

y=-x-3 is -1

slope=y2-y1/x2-x1=-3-15/8--10=-1

the equation of the line is

y-15= -1(x--10)

y= -x-10+15

y= -x+5
