Answer:

The roots of a function are the x-intercepts. By definition, the y-coordinate of points lying on the x-axis is zero. Therefore, to find the roots of a quadratic function, we set f (x) = 0, and solve the equation, ax2 + bx + c = 0.

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Answer:

slope: 1/2

y: intercept: (0;6)

so B

The equation of the line is y = x/2 + 6 which passes through the points (-6, 3) and (2, 7) option (B) is correct.

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

It is given that:

The line that passes through the points (-6, 3) and (2, 7)

The equation of the line:

y - 7 = (7 - 3)/(2 + 6)[x - 2]

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

y = (1/2)x - 1 + 7

y = x/2 + 6

Thus, the equation of the line is y = x/2 + 6 which passes through the points (-6, 3) and (2, 7) option (B) is correct.

Answer:

See below.

Step-by-step explanation:

You don't show what the function is, but I'll explain how to do it.

The average rate of change of function f(x), from x = a to x = b, is given by the fraction:

[tex] \dfrac{f(b) - f(a)}{b - a} [/tex]

Since I don't know what the function is, I cannot evaluate the function at x = a and at x = b, which in your case are x = 2 and x = 3, but you can do it.

Here are the steps you need to do:

1) Evaluate the function at x = 3. Get a value for f(3).

2) Evaluate the function at x = 2. Get a value for f(2).

3) Evaluate the following fraction, after writing the values for f(3) and f(2) that you found in steps 1) and 2) above.

[tex] \dfrac{f(3) - f(2)}{3 - 2} [/tex]

The denominator above is easy. It's just 1.

Try it and see what you get. You can write the function and your answer in the comments if you need more help.

Answer:

x = 5.25

Step-by-step explanation:

If I am understanding the question correctly, you are asking to find x when 4x=21? If this is the case, then all you must do is divide 21 by 4, then you get 5.25.

Answer:

11

Step-by-step explanation:

Do kcf (keep,change,flip)

First, covert 2 3/4 into an improper fraction

Then after you do that you get 11/4

so you do the equation 11/4 ÷ 1/4

when you do kcf it would be 11/4 × 4/1=

11/4×4/1=44/4 simplify divide both by 4 = 11

Answer:

x = 18.7

Step-by-step explanation:

Gerald's answer is almost correct.  

He just needs to switch the 14 and the x.

it should be

24/x = 18/14

solve for x by cross multiplication

18x = (24)(14)

18x = 336

x = 18.7

Answer:

a. $2.12

b. $6.45

c. $38.81

Step-by-step explanation:

a.

I'll convert 30.24 and 7% into fractions.

756/25 * 7/100

Cross cancel 756 and 100 (GCF is 4)

189/25 * 7/25

Convert above into a single fraction

(189 * 7)/(25 * 25)

Multiply 189 by 7, then 25 by 25.

1323/625

Divide, then round to the nearest cent

$2.1168 ≈ $2.12 in sales tax

b.

Like before, I'll convert $32.26 ($30.24 + $2.12) and 20% into fractions.

1613/50 * 1/5

Multiply 50 by 5.

1613/250

Divide, then round to the nearest cent.

$6.452 ≈ $6.45 in tip money

c.

This is probably the simplest part of the 3. Just add $30.24 + $2.12 + $6.45.

$30.24 + $2.12 + $6.45

$32.36 + $6.45

You pay a total of $38.81 for lunch.

Answer:

The different of the tax was 0.09 cents

Step-by-step explanation:

1. Find how much the tax was

Henry = (16/100) (9) = (0.16) (9) = $1.44

Ella = (17/100) (9) = (0.17) (9) = $1.53

2. Subtract the taxes

1.53 - 1.44 = 0.09 cent

Answer:

change in buyer tastes.

Step-by-step explanation:

Buyers now want more donuts than the other goods.

increase in the cost of donuts is more likely to decrease the amount of donuts consumed, as they would be more expensive

consumers expecting something doesn't necessarily change anything, as they haven't yet dropped and therefore it's unlikely they'd increase the demand until they actually were cheaper.

Coffee doesn't necessarily effect donut sales, unless stated in the question.

Answer:

a) 46° b) 66° c) 4 cm

Step-by-step explanation:

a) because it is isosceles triangle, therefore, 2 opposite angles, and angle sum of triangle is 180 so 180-67-67=46

b) because again, isosceles triangle so two opposite sides,

x+x+48=180

2x=132

x=66

c)because it is equilateral, so therefore all angles are 60 degrees and all sides equal.

Answer:

86.14 in.²

Step-by-step explanation:

Area of the composite figure = area of semicircle + area of rectangle + area of triangle

= (½πr²) + (L*W) + (½bh)

Where,

r = ½*6 = 3 in.

L = 8 in.

W = 6 in.

b = 16 - 8 = 8 in.

h = 6 in.

Plug in the values and solve

Area of composite figure = (½*π*3²) + (8*6) + (½*8*6)

= 14.14 + 48 + 24

= 86.14 in.²
