Answer:

Plot and connect (5,4), (3,0) and (7,0).

Step-by-step explanation:

This is in factored form and can be graphed directly from the equation. The equation shows the x-intercepts.

The x-intercepts are found by solving for x using the zero product rule.

(x-3)=0 so x = 3

(x-7) = 0 so x = 7

The intercepts are (3,0) and (7,0). Plot the points. The vertex will occur halfway between these points. 7-3 / 2 = 4/2 = 2. This means the axis of symmetry is at x = 5 and this is the x-coordinate of the vertex too.

Substitute x = 5 into the equation and solve for y.

-(5-3)(5-7) = -(2)(-2) = 4

The vertex is (5,4). Plot it and connect the points.

The value of the expression 16 -3/4 is ______.

Korvikt [17]

16-3/4=15 1/4

You can convert to fractions first, and then convert back to a mixed number like:

16/1-3/4 and when you add/subtract fractions you need a common denominator

64/4-3/4

61/4

15 1/4

Or you can convert your fraction to a decimal to get:

16-0.75

15.25

7v=2v-20 what is the answer

Ierofanga [76]

7v = 2v - 20

First, subtract 2v from both sides. / Your problem should look like: 7v - 2v = -20
Second, simplify 7v - 2v to 5v. / Your problem should look like: 5v = -20
Third, divide both sides by 5. / Your problem should look like: v = $- \frac{20}{5}$
Fourth, simplify $\frac{20}{5}$ to 4. / Your problem should look like: v = -4

Answer: v = -4
