Answer:5x
Step-by-step explanation:
Answer: 5x
Step-by-step explanation:
We would need to know what X is first. For example, is X is 7; 5 times x (7)
Would equal 35
5x7=35
but we don't know what X is so we leave it as 5x
1) h(x) = -3x + 5; Find h(-1-2)
Answer:
h(-1) = 8
h(-2) = 11
h(-12) = 41
Step-by-step explanation:
h(x) = -3x + 5
h(-1) = -3(-1) + 5 = 3 + 5 = 8
h(-2) = -3(-2) + 5 = 6 + 5 = 11
h(-12) = -3(-12) + 5 = 36 + 5 = 41
FIND THE QUADRATIC FUNCTION DETERMINED BY EACH TABLE
X -2 -1 0 1 2 3
Y 4 0 -2 -2 0 4
Answer:
x² - x - 2 = 0
Step-by-step explanation:
plotting the graph of x and y,we have that the root of the equation is -1 or 2
x = -1 or 2
the eqn therefore is;
x² - (sum of the root)x + (product of the root) =. 0
x² - (-1+2)x + (-1*2) = 0
x² - x - 2 = 0
Applying the Factor Theorem, it is found that the quadratic function is:
[tex]p(x) = x^2 - x - 2[/tex]
------------------------
The Factor Theorem states that if a polynomial [tex]p(x)[/tex] has roots [tex]x_1, x_2, ..., x_n[/tex], it is described by the following equation:
[tex]p(x) = a(x - x_1)(x - x_2)...(x - x_n)[/tex]
In which a is the leading coefficient.
For this quadratic function, the roots are [tex]x_1 = -1, x_2 = 2[/tex], as [tex]y(-1) = y(2) = 0[/tex], thus:[tex]p(x) = a(x - (-1))(x - 2)[/tex]
[tex]p(x) = a(x + 1)(x - 2)[/tex]
[tex]p(x) = a(x^2 - x - 2)[/tex]
When x = 0, p(x) = -2, and we use this to find a.
[tex]p(x) = a(x^2 - x - 2)[/tex]
[tex]-2 = a(0^2 - 0 - 2)[/tex]
[tex]2a = 2[/tex]
[tex]a = \frac{2}{2}[/tex]
[tex]a = 1[/tex]
Thus, the quadratic function is:
[tex]p(x) = x^2 - x - 2[/tex]

Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define systems
5x - 2y = 9
3x + 4y = -5
Step 2: Rewrite systems
10x - 4y = 18
3x + 4y = -5
Step 3: Solve for x
Add to equations together: 13x = 13Divide 13 on both sides: x = 1Step 4: Solve for y
Define: 3x + 4y = -5Substitute in x: 3(1) + 4y = -5Multiply: 3 + 4y = -5Isolate y term: 4y = -8Isolate y: y = -2And we have our final answer!

C personalities are organized and controlled. They take their time completing tasks accurately, like to research things thoroughly, and are always prepared. Because they put so much time and effort into everything they do, they hate to be criticized. They are perfectionists at heart and take even the smallest complaint personally. This makes them extremely difficult to confront. The best way to approach it is to focus on parts of the problem largely out of the C personality’s control or aspects of the problem they might not have considered. Make it clear that you appreciate all of their efforts and that you’re bringing something to their attention because it’s a variable that they need to have in the equation in the future. No matter what, don’t frame the conflict as a personal attack. If you do, the C personality will likely become resentful and go out of their way to avoid future interactions with you.%%%%%%%%%%%%%%%
A scientist discovered a new type of bacteria that will grow at a rate of 3 cells every 2 seconds. If the scientist starts with one bacteria cell in a petri dish, what equation could predict the amount of cells in the dish after x seconds? Please help me
Answer:
1.5 x cells
Step-by-step explanation:
3 cells every 2 second
1.5 cells per second

geometry, is this right if not whats the answer ?
==============================================
Explanation:
Because S and T are midpoints of segments PQ and QR, we know that ST is a midsegment of triangle PQR. Consequently, this means ST is parallel to PR.
From the same side interior angle theorem, the angles (11x-3) and (5x-9) are supplementary angles. This is only true because of the parallel lines.
So we can say the following:
(angle P) + (angle S) = 180
(5x-9) + (11x-3) = 180
(5x+11x) + (-9-3) = 180
16x - 12 = 180
16x = 180+12
16x = 192
x = 192/16
x = 12
--------------------------
Use this to find angle PST
angle PST = 11x-3
angle PST = 11*12-3
angle PST = 132-3
angle PST = 129 degrees
--------------------------
Optionally we can find angle QPR
angle QPR = 5x-9
angle QPR = 5*12-9
angle QPR = 60-9
angle QPR = 51 degrees
As a check, adding the two angles we found should get us 180
(angle PST)+(angle QPR) = 129+51 = 180
The answer checks out.

Annabelle is ordering a taxi from an online taxi service. The taxi charges $2 just for the pickup and then an additional $1.50 per mile driven. How much would a taxi ride cost if Annabelle is riding for 6 miles? How much would a taxi ride cost that is mm miles long?
Answer:
$11Step-by-step explanation:
Step one:
given
Taxi charges =$2
Additional charges =$1.50 per mile driven
Step two:
Required
The cost of the ride for a 6miles long drive
let the number of miles be x
and the total charges be y
The cost function is expressed as
[tex]y=1.5x+2[/tex]------------1
hence for x=6
y=1.5(6)+2
y=9+2
y=11
Therefore the cost of a 6miles drive will be $11

How do you find the angle of a right triangle with 3 sides?
Step-by-step explanation:
Step 1 The two sides we know are Adjacent (6,750) and Hypotenuse (8,100).
Step 2 SOHCAHTOA tells us we must use Cosine.
Step 3 Calculate Adjacent / Hypotenuse = 6,750/8,100 = 0.8333.

C(represent a concrete thing)
D(compare two different things)
Answer:
B(represent an abstract idea)
Step-by-step explanation:
A symbol is a stylistic figure whose essence is to use a word or phrase to refer to another, usually abstract term, to which it refers.
What symbolism means in every sphere is precisely the reference by one term to another term that symbolizes.
A symbol consists of a concrete material designation which refers to some abstract concept.

Answer:
Because scientific notation has to be in between 1 and 10, you would need this to be 5.2. Count the spaces and since its getting smaller your exponent is negative.
