For what value of x does f(x) = g(x) when f(x) = 4x - 10 and g(x) = 0.5x + 7.5

Answer:x=5

Step-by-step explanation:

4x - 10 = 0.5x + 7.5

-0.5x       -0.5x

3.5x - 10 = 7.5

       +10    +10

3.5x = 17.5

divide both sides by 3.5 and you get x=5

Which equation represents the line that is perpendicular to and passes through (-12,6)?.
Evgesh-ka [11]

The equation that represents the line that is perpendicular is

3y + 5x = -42

The standard equation of a line in point-slope form is expressed as:

y-y_1=m(x-x_1)

  • m is the slope of the lne
  • (x1, y1) is any point on the line.

  • Given the equation y = 3/2x + 1, the slope of the line is 3/5

  • The s<u>lope of the line perpendicular</u> is -5/3

Substitute the point (-12, 6) and the slope m = -5/3 into the equation above to have:

y-6=-5/3(x-(-12))\\3(y-6)=-5(x+12)\\3y-18=-5x-60\\3y = -5x - 60 + 18\\3y + 5x = -42\\

Hence the equation that represents the line that is perpendicular is

3y + 5x = -42

Given the functions f(x) = x² – 8 and g(x) = 4-x, determine the equation for the combined function
ElenaW [278]

Answer:

y=x^2+x-12

Step-by-step explanation:

f(x) = x² – 8 and g(x) = 4-x

y=f(x) - g(x)

y=(x² – 8) - (4-x)

y=x^2-8-4+x\\y=x^2+x-12

Select from the drop-down menus to correctly complete each statement. 17.2 is 17.2 units to the ____ of zero on a number line. T
Fudgin [204]
Hello!

The number line progresses from negative infinity (extreme left) to positive infinity (extreme right). Beginning at zero, the numbers increase in value as they move to the right and decrease in value as they move to the left.

With this knowledge, we can look at the number 17.2 (a positive number) and conclude that it is placed 17.2 units to the right of zero on the number line.

The opposite of 17.2 would be (-17.2). Again, looking at this number (a negative number), we can conclude that it is placed 17.2 units to the left of zero on the number line.

I hope this helps!
