Answer:
-2x-16
Step-by-step explanation:
so what you are going to do for this is use the distributive property. 2x will be multiplied by x and -4. then you will take 4 and multiply x and -4. then you combine your alike terms. 2x-8x+4x-16 you should get -2x-16
The equivalent expression after multiplying is 2(x² - 2x - 8).
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
(2x + 4) (x - 4)
Remove the parenthesis.
2x² - 8x + 4x - 16
Add like terms.
2x² - 4x - 16
Taking out the common factor.
2 (x² - 2x - 8)
Thus,
The final expression is 2(x² - 2x - 8).

What is the image of (3, 6) when it is translated along the horizontal vector -2,0?
Answer: (1,6)
The vector <-2,0> means we shift the input point two units to the left.
This is the same as writing the rule [tex](x,y) \to (x-2,y)[/tex]
Subtract 2 from the x coordinate. The y coordinate stays the same.
After the translation the point becomes P'(1, 6).
What is the difference between upward, downward, leftwards and rightwards translation?Upward translation : [k] units = When the upward translation take's place then, each point will have its y - coordinate shifted upwards by +k units.Downward translation : [k] units = When the downward translation will take place then, each point will have its y - coordinate shifted downwards by -k units.Leftward Translation : [k] units = When the leftward translation will take place then, each point will have its x - coordinate shifted by -k units to the left.Rightward Translation : [k] units = When the rightward translation will take place then, each point will have its x - coordinate shifted by +k units to the rightGiven is a coordinate point (3, 6).
The horizontal vector is given by -
A = - 2i + 0j + 0k
A = - 2j
When the point is translated along the vector, then, we can write -
P(3, 6) → P'(3 - 2, 6) → P'(1, 6)
P'(1, 6)
Therefore, after the translation the point becomes P'(1, 6).

A gene is composed of two alleles. An allele can be either dominant or recessive. suppose that a husband and a wife who are both carriers of the sickle-cell anemia allele but do not have the disease, decide to have a child. because both parents are carriers of the disease, each one has a dominant normal cell allele (S), and one recessive sickle-cell allele (s). Therefore the genotype of each parent is Ss. Each parent contributes one allele to his or her offspring with each allele being equally likely.
a.List the possible genotypes of their offspring.
b. what is the probability that the offspring will have sickle cell- genotype ss?
c. what is the probability that the offspring will not have sickle cell but still be a carrier (one normal cell allele and one sickle cell allele)
Answer:
a) SS, Ss, ss
b) 1/4
c) 1/2
Step-by-step explanation:
According to this question, a gene coding for possession or not of sickle cell has two alleles. Allele "S" codes for normal cell while allele "s" codes for sickle cell. A heterozygous individual or carrier will have a "Ss" genotype.
If two carriers of the sickle cell condition decide to have a child and mate i.e. Ss × Ss, the following gametes will be produced by each parent: S and s.
a) Using these gametes (S, s) in a punnet square (see attached image), the four possible offsprings with the following genotypes will be produced: SS, Ss and ss in a GENOTYPIC RATIO 1:2:1.
b) Since offsprings with the genotype "ss" will possess the sickle cell condition/phenotype, the probability of offsprings that will have sickle cell is 1/4 i.e. 1 out of 4 possible offsprings
c) Also,carrier genotype will be "Ss", therefore, the probability that the offspring will not have sickle cell but still be a carrier (one normal cell allele and one sickle cell allele) will be 2/4 or 1/2 i.e. 1 out of 2 possible offsprings.

Planet Earth has a mass of 5.9726 × 10 24 kilograms. And although 70% of the Earth's surface is made of water, the water's mass is only 5 × 10 -4 percent of the Earth's total mass. Use scientific notation to estimate the mass of the planet's water. In your final answer, include all of your estimates and calculations.
Answer:
i don't it is correct or not........
Step-by-step explanation:
The Mass of Earth = 5.9742 × 1024 kilograms == == The Earth is (As of May 2000) is thought to be approximately 5.972 sextillion (5,972,000,000,000,000,000,000) metric tons.
A metric ton is a thousand kilograms, or 2,204.62 pounds.
Approximately 6,000,000,000,000,000,000,000,000 (6x1024) kilograms.
Answer:
Mass on water on earth is 29.5×10^20 kg approximately.
Step-by-step explanation:
Mass of earth= 5.9726 × 10^ 24 kg
water's mass is only 5 × 10 -4 percent of the Earth's total mass.
so mass of water = 5.9726×10^24 kg×5×10^-4=29.8603×10^20kg approximately

The graph of the reciprocal parent function f(x)=1/x, is shifted 6 units down and 1 unit to the right to create the graph of g(x). What function is g(x)?
A. g(x)=1/x+6-1
B. g(x)=1/x-1-6
C. g(x)=1/x-6-1
D. g(x)=1/x+1-6
Transformations are used to move a function from one position to another. The new function g(x) is [tex]g(x) = \frac{1}{x-1} - 6[/tex]
Given that
[tex]f(x) = \frac 1x[/tex]
When shifted 6 units down. the rule of transformation is:
[tex](x,f(x)) \to (x,f(x) - 6)[/tex]
So, we have:
[tex]f'(x) = f(x) - 6[/tex]
[tex]f'(x) = \frac 1x - 6[/tex]
When shifted 1 unit left. the rule of transformation is:
[tex](x,g(x)) \to (x -1,f'(x))[/tex]
So, we have:
[tex]g(x) = f'(x - 1)[/tex]
[tex]g(x) = \frac{1}{x-1} - 6[/tex]
Hence, the new function g(x) is [tex]g(x) = \frac{1}{x-1} - 6[/tex]

What is the probability that 5 boys and 2 girls get the movie tickets?
Answer:
0.3
Step-by-step explanation:
The number of ways to choose 5 boys from 6 is ₆C₅.
The number of ways to choose 2 girls from 4 is ₄C₂.
The number of ways to choose 7 people from 10 is ₁₀C₇.
P = ₆C₅ ₄C₂ / ₁₀C₇
P = 6 × 6 / 120

2x + 7 = 5x - 8 (x - 4)
Answer:
x=5
Step-by-step explanation:
2x + 7 = 5x - 8 (x - 4)
Distribute
2x+7 = 5x - 8x +32
Combine like terms
2x+7 = -3x+32
Add 3x to each side
2x+7+3x = -3x+32+3x
5x+7 = 32
Subtract 7 from each side
5x+7-7 = 32-7
5x = 25
Divide by 5
5x/5 = 25/5
x=5

F (x) = x^2 + 6x+8 = F = x + 6 + [tex]\frac{8}{x}[/tex]
Step-by-step explanation:
Move all the expressions to the left side of the equation.
F(x)−x2−6x−8=0
Multiply F by x.
Fx−x2−6x−8=0
Move all terms not containing F to the right side of the equation.
Fx=x2+6x+8
Divide each term by x and simplify.
F = x + 6 + [tex]\frac{8}{x}[/tex]

The sum of 6 consecutive odd numbers is 204. What is the fourth number in this sequence?
Answer:
35
Step-by-step explanation:
1. Set up a equation.
2. X is the first, so the ones after x are x+2, x+4, x+6, x+8, and x+10.
3. That means that x+x+2+x+4+x+6+x+8+x+10=204.
4. Simplify. You would get that 6x+30=204.
5. Solve for x. 6x=174, so x=29.
6. Get the fourth number in the sequence. 29+6=35.
Answer: The fourth number in this sequence is 35.

Answer: D
Step-by-step explanation:
(Using the formula in my attachment)
x^2 − 6x + 19
(x - 3)^2 = x^2 - 6x + 9
9 - e = 19
e = -10
(x - 3)^2 - e
(x - 3)^2 - - 10
(x - 3)^2 + 10

What is System of Equation?The system of equation is set of equations which have a common solution.
The figure shows the graph of two equations, these equations are a straight line function and the common solution is represented by a point in the image.
The solution of the system of equation can be obtained both by solving using substitution method and even by plotting the graph and finding the intersection point.
The system of equation is,
y = 2x - 7
y = -x -1
The value of y from equation 2 will be substituted in equation 1
-x -1 = 2x -7
