Quadratic Equation to Standard Form

Answer:i think D but i would see what others say first

Step-by-step explanation:

Answer:

B) 1p - 0.4p

Step-by-step explanation:

40% to a decimal is 0.4, so that immediately marks "A" and "C" wrong.

Now what you're trying to find is the expression itself, so you want to first look for keywords, 'cause sometimes they can just give away the answer.

"A" says you're multiplying (a variable beside a number means to multiply)

"B" says you're subtracting 1p (1 x p) and 0.4p (0.4 x p)

"D" says you're adding 1p (1 x p) and 0.4p (0.4 x p)

So, now you look over the question.

Really you can mark "A" wrong. Now it's just between "B" and "D."

When you use percentages and an item, you're taking it OFF the price. So, the answer is B.

Answer:

No, they are not inverses.

Step-by-step explanation:

To find out if this are inverses we will have to switch the x and y in one of the equations. Let's do it with the second equation:

(Remember that f(x)/g(x) and y are virtually the same)

y = -4x + 2

Switch x and y

x = -4y + 2

Now solve for y

x - 2 = -4y

[tex]-\frac{x}{4} + \frac{2}{4} = y\\-\frac{x}{4} + \frac{1}{2} = y[/tex]

Therefore, the 2 functions in the question are not inverses of each other because the actual inverse has a negative in front of the -x/4.

Answer:

A. 3 bags of popcorn

F. $12.25

G. 6 bags of popcorn

Heya, I hope this helped you! If you divide 3.5 by 2, it is $1.75 for each bag of popcorn. I hope this helped! <3

Answer: A. Murderer bought three bags

F. $21.00

G. 6 bags

Step-by-step explanation:

divide 3.50 by 2 gives you 1.75 and 1.75+3.50= 5.25 which is the total spent.

1.75 x 6 is equal to 10.50 and 12.82-2.32= 10.50

Answer:

(2,1) because if you plug in 2 for for X you get 4 if you plug in 1 for y you get 6, 4 + 6 is equal to 10

Step-by-step explanation:

Answer: it's definitely not A(4,7) because you would get -1/4x+6=y

Answer:

[tex](f+g)(x)=x^2-4x-21[/tex]

Step-by-step explanation:

We are given:

[tex]f(x)=x^2-5x-14\text{ and } g(x)=x-7[/tex]

And we want to find:

[tex](f+g)(x)[/tex]

This is equivalent to:

[tex]=f(x)+g(x)[/tex]

Therefore, by substitution:

[tex]=(x^2-5x-14)+(x-7)[/tex]

Rearranging gives:

[tex]=(x^2)+(-5x+x)+(-14-7)[/tex]

Combine like terms:

[tex]=x^2-4x-21[/tex]

Answer:

-212

Step-by-step explanation:

This question seems to be incrementing by steps of -4, starting at -8.  To get the 52'nd term, we can simply start at the first term and add that -4 51 more times.

Assuming that negative eight is the first term then, we get:

-8 - 4 * 51

= -8 - 204

= -212

The 52nd term of the sequence will be -212.

A sequence of events or things is a number of events or things that come one after another in a particular order.

Given a sequence, -8, -12, -16,...

nth term of a sequence is given by

an = a + (n-1)*d

a(-212) = -8 + (52-1)*-4

a(-212) = -8-204

a(-212) = -212

Hence, The 52nd term of the sequence will be -212.

Answer:

The simple interest is $58.5

Step-by-step explanation:

Mathematically;

Simple interest = PRT/100

where p is principal = $300

R is rate = 6.5%

T is time = 3 years

Substituting these values in the simple interest equation, we have that;

S.I = (300 * 6.5 * 3)/100 = $58.5

5) The height of a rocket after it is launched

For this case, what you should do is remember the kinematics expressions where we have:

a

v = a * t + vo

y = a * t ^ 2 + vo * t + i

Where,

a: acceleration

v: speed

y: vertical position

t: time

vo: initial speed

yo: initial position

We observe that the expression for the given position is given by a quadratic expression.

Answer:

AB = 4

[tex]m\angle E=30^\circ[/tex]

Step-by-step explanation:

Similar shapes

Two figures are similar if the ratios of the lengths of their corresponding sides are equal. The corresponding angles are also congruent.

Being ABCD and EFGH similar, the ratio of the lengths of AB and EF is equal to the ratio of the lengths of AD and EH, thus:

[tex]\displaystyle \frac{AB}{EF}=\frac{AD}{EH}[/tex]

Solving for AB:

[tex]\displaystyle AB=\frac{AD}{EH}\cdot EF[/tex]

Since AD=6, EH=1.5, and EF=1:

[tex]\displaystyle AB=\frac{6}{1.5}\cdot 1[/tex]

AB = 4

Since angle A is congruent to angle E:

[tex]m\angle E=m\angle A[/tex]

[tex]\mathbf{m\angle E=30^\circ}[/tex]

Answer:

Given:

Student ticket price = $7

A group of 4 students and 3 adults paid $64  in all for movie tickets.

To find:

Each of the adult ticket cost.

Solution:

Let x be the cost of each adult ticket.

Then, cost of 3 adult tickets = 3x.

Cost of 1 student ticket = $7

Cost of 4 student ticket = $7(4)

According to the question,

[tex]7(4)+3x=64[/tex]

[tex]28+3x=64[/tex]

[tex]3x=64-28[/tex]

[tex]3x=36[/tex]

Divide both sides by 3.

[tex]x=12[/tex]

Therefore, the cost of each adult ticket is $12.
