how do I do this :( I tried but I can’t figure out how to

Answer:

f(-2) = 21

Step-by-step explanation:

Step 1: Define

f(x) = 3x² - 4x + 1

f(-2) is x = -2

Step 2: Substitute and Evaluate

f(-2) = 3(-2)² - 4(-2) + 1

f(-2) = 3(4) + 8 + 1

f(-2) = 12 + 9

f(-2) = 21

Answer:

y = 1.68x

Step-by-step explanation:

The markup rate of a product or service refers to how higher the selling price is than the total production cost. In this case, this company doesn't produce the bikes, instead it purchases them from a wholesaler, distributor or even the factory, and then resells them in order to make a profit.

E.g. Beach Bicycles purchases two-seater bikes at $200 each, and then it will resell them to their customers at 1.68 x $200 = $336. The total markup in this example is $136, which represents $136/$200 = 68% of the purchase price.

Answer:

y=6-3x

Step-by-step explanation:

factor out common terms 2(3x+y)=12divide both sides by 2

3x+y=[tex]\frac{12}{2}[/tex] simplify 3x+y=6 subtract 3 from both sides

y=6-3x

Answer:

900 grams of flour 150x6=900

3 eggs 450/150=3

Answer:

x = 17

Step-by-step explanation:

The two indicated angles are corresponding and congruent, thus

11x - 31 = 8x + 20 ( subtract 8x from both sides )

3x - 31 = 20 ( add 31 to both sides )

3x = 51 ( divide both sides by 3 )

x = 17

Step-by-step explanation:

Given:

Coordinates of point C are (-3,6).

Point B(0,5.5) is the midpoint of AC.

To find:

The coordinates of A.

Solution:

Let the coordinates of point A are (a,b).

Formula for midpoint:

[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

Using the above formula, the midpoint of A(a,b) and C(-3,6) is

[tex]B=\left(\dfrac{a+(-3)}{2},\dfrac{b+6}{2}\right)[/tex]

[tex](0,5.5)=\left(\dfrac{a-3}{2},\dfrac{b+6}{2}\right)[/tex]

On comparing both sides, we get

[tex]\dfrac{a-3}{2}=0[/tex]

[tex]a-3=0[/tex]

[tex]a=3[/tex]

and,

[tex]\dfrac{b+6}{2}=5.5[/tex]

[tex]b+6=11[/tex]

[tex]b=11-6[/tex]

[tex]b=5[/tex]

Therefore, the coordinates of point A are (3,5).

Step-by-step explanation:

p = -4

3p² - 18(-2 - p)

plug in p

3(-4)² - 18(-2 - (-4))

solve the exponent

3(16) - 18(-2 - (-4))

solve within the parentheses

3(16) - 18(-2 + 4)

3(16) - 18(2)

multiply each expression

48 - 36

subtract

Answer:

Step-by-step explanation:

This is an arithmetic sequence, in which a set number is added to the previous term to get the next term. The number added is figured out by subtracting the 1st term from the 2nd term and the 2nd term from the 3rd term.

Now that we know the number is 3, we can complete the sequence:

4, 7, 10, 13, 16, 19, 22

We will add all the terms up to get 91.

Answer:

[tex]\sqrt{2}/2[/tex]

Step-by-step explanation:

Making a unit circle will be very helpful if you don't already have one. You will use it for years to come.

Step-by-step explanation:

Let x equal the width of the box and x + 15 equal the length of the box.  Subtract 6 (the amount cut out) from both of the these to get the following terms: (x+9) and (x-6).  These are the length and width of the box respectively.  We also know that the height of the box is 3.  Plugging these into the formula for the volume of a box gives you:

3(x+9)(x-6)=1092

Expanding this out gives:

3x^2+9x-162=1092

Subtract 1092 from both sides to make the quadratic equation equal zero.  Plug the a, b and c coefficients into the quadratic formula (or factor) to find x.

3x^2 +9x-1254 = 0

a = 3       b = 9        c = -1254

I hope this helps :)

Answer: 40 chocolates

Step-by-step explanation:

Answer:

A) ∠ABD is a right angle.

E) m∠ABD = 90°

Step-by-step explanation:

just took the test

∠ABD is a right angle and ∠ABD = 90° will be correct for the given angles.

An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.

The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.

The angle is the measurement of the angular distance for example for linear motion we have a meter inch but for angular rotation, we don't have the measurement so the angle is useful to measure the angular rotation.

Given that,

Angle A B D is a right angle.

The right angle is a 90-degree angle.

So,

m∠ABD = 90°

Hence "∠ABD is a right angle and ∠ABD = 90° will be correct for the given angles".

Answer:

42

Step-by-step explanation:

The product of the prime factors of 1764 is

1764 = 2² × 3² × 7² , thus

[tex]\sqrt{1764}[/tex]

= [tex]\sqrt{2^{2}(3^{2} )(7^{2} ) }[/tex]

= [tex]\sqrt{2^{2} }[/tex] × [tex]\sqrt{3^{2} }[/tex] × [tex]\sqrt{7^{2} }[/tex]

= 2 × 3 × 7

= 42

Answer:

no as the answer would be a decimal

Step-by-step explanation:

an easier way to know is to add up all the digits

3 + 9+0 +5+2= 19 and if that number is a multiple of 3 then it will be divisible by 3

this works for any number that should be divided by 3

example

is 2345 divisible by 3

2+3+4+5 =14 so no it is not divisible by 3

example

is 12345 divisible by 3

1+2+3+4+5 =15 so yes it is divisible by 3
