8.2 because you would multiply 0.5 by 16.4 which equals 8.2

The fabulous footballers scored an incredible 55 points at last nights football game. interestingly, the number of field goals w
MA_775_DIABLO [31]

Answer is option II

Given that there are 7 points earned for each touch down and 3 points for each field goal.

t represents thenumber of touchdowns and f the number of field goals.

Then points scored would be 7(t) +3(f) = 7t+3f

Hence we get 7t+3f =55

Also number of field goals was 1 more than twice the number of touchdowns.

Twice the touchdowns = 2(t)

f = 2t+1

Hence the two equations would be:

f = 2t+1

7t+3f =55

Hence option ii is the right answer.

What is 2x^2+9x-18 in vertex form?
atroni [7]

Complete the square:

2<em>x</em>² + 9<em>x</em> - 18

2(<em>x</em>² + 9/2 <em>x</em>) - 18

2(<em>x</em>² + 9/2 <em>x</em> + 81/16 - 81/16) - 18

2(<em>x</em>² + 2 (9/4) <em>x</em> + (9/4)²) - 81/8 - 18

2(<em>x</em> + 9/4)² - 225/8

If you're not familiar with the method, the idea is to get a quadratic from the standard form

<em>ax</em>² + <em>bx</em> + <em>c</em>

into its vertex form

<em>a</em> (<em>x</em> - <em>h</em>)² + <em>k</em>

where (<em>h</em>, <em>k</em>) is the vertex of the parabola associated with the quadratic.

Expand the vertex form to get

<em>a</em> (<em>x</em>² - 2<em>xh</em> + <em>h</em>²) + <em>k</em>

<em>ax</em>² - 2<em>ahx</em> + <em>ah</em>² + <em>k</em>

For the two forms to be equivalent, we must have

-2<em>ah</em> = <em>b</em>

<em>ah</em>² + <em>k</em> = <em>c</em>

which means

<em>h</em> = -<em>b</em>/(2<em>a</em>)

<em>k</em> = <em>c</em> - <em>ah</em>² = <em>c</em> - <em>b</em>²/(4<em>a</em>)

In this case, <em>a</em> = 2, <em>b</em> = 9, and <em>c</em> = -18, so

<em>h</em> = -9/(2 • 2) = -9/4

<em>k</em> = 18 - 9²/(4 • 2) = -225/8

Use the graph of the function f(x) = 2x + 2 to find the value of y when x = 2.
Tatiana [17]

Answer:

6

Step-by-step explanation:

Note: f(x) = y

f(x) = 2x + 2      x = 2

Step 1: Plug in 2 into x.

f(x) = 2(2) + 2

Step 2: Then multiply 2 times 2.

f(x) = 4 + 2

Step 3: Add.

f(x) = 6

Alex17521 [72]
Nayeli - 4x19= 76 total candies
jayden- 5x15= 75 total candies
so nayeli has 1 more piece of candy than jayden does.
