Answer: h(4) = 7

Step-by-step explanation:

Given h(x)= 2x-1

Find h(4)

Solution:

Substitute x = 4 into the equation

h (4) = 2 (4) - 1

h (4) = 8 - 1

Solve for y x+2y=6. what's the answer

Luda [366]

Solve for y

x+2y=6

Add (-x) to both sides:

x + 2y + (-x) = 6 + (-x)

Simplify:

2y = 6 - x

Divide both sides by 2

2y/2 = (6-x) / 2

2y/2 = 6/2 - x/2

y = 3 - x/2

Given parallelogram ABCD, diagonals AC and BD intersect at point E. AE=2x, BE=y+10, CE=x+2 and DE=4y−8. Find y.

hodyreva [135]

9514 1404 393

Answer:

B. 6

Step-by-step explanation:

The diagonals of a parallelogram intersect at their midpoints, so ...

DE = BE

4y -8 = y +10

3y = 18 . . . . . . . add 8-y

y = 6 . . . . . . . . divide by 3

<em>Additional comment</em>

The value of x is found the same way:

2x = x+2 ⇒ x = 2

Which of the following equations represents the graph shown?

melomori [17]

Answer: Last option.

Step-by-step explanation:

The equation of the line in slope-intercept form is:

$y=mx+b$

Where m is the slope and b the intersection with the y-axis.

You can observe in the graph that the line passes through the origin, then:

$b=0$

Choose two points of the line and calculate the slope with:

$m=\frac{y_2-y_1}{x_2-x_1}$

Points: (2,3) and (-2,-3)

Substitute values, then the slope is:

$m=\frac{-3-3}{-2-2}=\frac{-6}{-4}=\frac{3}{2}$

Substituting "m" and "b" into $y=mx+b$ , you get that the equation is:

$y=\frac{3}{2}x$

This can be written as:

$f(x)=\frac{3}{2}x$
