Answer 1

Answer:

f(2) = 12

f(x) = 7, x = -3, 1

Step-by-step explanation:

a)

plug in x as 2

f(x) = 2^2 + 2(2) + 4

f(x) = 4 + 4 + 4

f(x) = 12

b)

replace f(x) with 7

7 = x^2 + 2x + 4

x^2 + 2x - 3 (move 7 to other side)

Factor

ac: -3x^2

b: 2x

split b into 3x, -x

(x^2 -x) + (3x - 3)

    ↓             ↓

  x(x-1)  +  3(x-1)

Factor: (x-1)(x+3) = 0

Solve using Zero Product Property:

x - 1 = 0, x + 3 = 0

x = 1, x = -3

Cheddar cheese cost 5.25$ per pound. Which equation best represents y, the total cost of x pounds of cheddar cheese? Best answer gets brainlist

Answers

Answer: y = 5.25x

Step-by-step explanation:

The cost of one pound of cheddar cheese is $5.25.

The number of cheese purchased is x.

The total cost of cheese would therefore be the cost of one pound of cheese multiplied by the number of pounds of cheese purchased:

= 5.25 * x

Full expression is therefore:

y = 5.25 * x

y = 5.25x

The image provided below, I find very helpful when trying to solve difficult problems such as this one.

We use the same relationship, the only difference is we are given expressions and numbers for the segments

If the product of the segments in one chord equal the product of the segments in the other chord then,

x * 6 = 8 * ( x - 1 )

Or 6x = 8 ( x - 1 )

Now we solve for

Step 1 distribute the 8

8 * x = 8x

8 * -1 = -8

We now have 6x = 8x - 8

step 2 subtract 8x from each side

6x - 8x = -2x

8x - 8x cancels out

we now have -2x = -8

step 3 divide each side by -2

-2x / -2 = x

-8 / - 2 = -4

we're left with x = 4

If the measure of angle 0 is 7/6. The equivalent measurement in degrees is
|blank| °

Answers

Answer:

the angle in degree is 30°

If the measure of the angle in radian form is 7π/6 then it is 210° in degrees form.

What is angle?

An angle is basically an inclination of surface towards a object. It is measured in degrees as well as in radian.

How to convert angle into degrees?

We have been that the angle is 7π/6 and we have to convert this angle into degrees.

We have to just put π=180 to convert the radian form into degrees.

Angle=7*180/6

=7*30

=210°

Hence if the measure of the angle in radian form is 7π/6 then it is 210° in degrees form.

They argue that it interrupts classes in many ways. Students may forget to do their homework as they concentrate on the Spirit Week themes. A few students skip classes and some go to a different lunch period. Students spend extra time in the bathrooms combing their hair and adjusting their outfits. Some students goof around in class and find it hard to settle down. If Spirit Week isnt canceled, teachers warn that school will no longer be a good place to learn.We, the students, feel that Spirit Week encourages us to be better students. Spirit Week is a way for us to show our creativity. For example, last year we had a 70s theme. Students learned how a person dressed during this decade, and they tried to imitate those fashions. Such a theme teaches us about culture and history. Spirit week also gives us feelings of pride. At the end of the week, we wear our school colors and support our basketball team against our rivals, the Wildcats. Finally, we feel that Spirit Week teaches us how to work in groups and how to pan and organize an event. Everyone loves Spirit Week. We ask the Harrison School Board to consider our plea and save Spirit Week
