Write an equation that is perpendicular to x-3y=2 and contains the point (2,4)

Mathematics

Kisachek [45]3 years ago

perp to x-3y=2 thru (2,4)

For perpendicular we swap the coefficients on x and y, negating one

3x + y = some constant

We get the constant in the obvious way from the point

3x + y = 3(2) + 4 = 6 + 4 = 10

Answer: 3x + y = 10

Which equation has the least steep graph?
gizmo_the_mogwai [7]

9514 1404 393

Answer:

   C.  y = 1/2x +2

Step-by-step explanation:

The magnitude of the slope is the measure of "steepness." The slope is the coefficient of x in these equations. Here those values are ...

  4, 3/4, 1/2, 10

Of these, 1/2 is the smallest (least steep). 1/2 is the slope in the equation ...

  y = 1/2x +2

The area of a triangle is 2/5 square feet. What is the base of the triangle if the height is 6/5 feet?
olga nikolaevna [1]

Answer:

2/3 feet.

Step-by-step explanation:

The formula for finding the area of a triangle is  A = (B x H)/2. Or, area is equal to base times height, all divided by two. In your case, we don't know the base. If we substitute in values, we get 2/5 = (B x 6/5)/2.

Next, we have to multiply both sides by two, to cancel the "/2." That results in 4/5 = B x 6/5. Then, to isolate the variable, we have to divide both sides by 6/5. 4/5 ÷ 6/5 is 4/5 x 5/6. The fives cancel out, and we are left with 4/6.

Finally, we simplify! 4/6 simplifies to 2/3.

Given the equation f(x) = 4x - 3, what is the value of f(-3)?<br> f(-3) =
nalin [4]

Answer: f (3)=5

Step-by-step explanation:How you start the equation is by plugging

3

into both of the

x

's in the problem to make it:

f

(

3

)

=

3

(

3

)

−

4

Next, you multiply the

3

(

3

)

to get

9

and subtract

4

. So in the end, you leave the

f

(

3

)

and

9

−

4 is

5

, so the

y

in the equation is

5

.
