Evaluate the following polynomial if x = -3
\large x^2-5x+12
Answer: 36
Step-by-step explanation: If you're asking what the expression equals after plugging X's value in, this should leave you with an expression of -3^2 - 5(-3) + 12. By following the order of operations, you should receive an answer of 36.
If the coordinates of A are (1, 1) and the midpoint of AB is (0,0.5), then the coordinates of B are -
Answer:
B (-1, 0)
Step-by-step explanation:
( in portuguese )
o ponto médio é calculado pela soma das abcissas a dividir por 2 e pela somas das ordenadas a dividir por 2, então sendo que se sabe o valor final, e um ponto fica :
(1+x)÷2 = 0 ⇔ x = -1
(1 + y) ÷ 2 = 1/2⇔ y=0

Step-by-step explanation:
The area of the shaded section above is [tex]\frac{24}{80}[/tex], which means 24 boxes out of 80 are shaded. It can be reduced to its lowest term:
[tex]\frac{24}{80}[/tex] ÷ [tex]\frac{8}{8}[/tex] = [tex]\frac{3}{10}[/tex]Now, that we know the lowest term, we have to look for similar fractions based on the product for each choice.
A. [tex]\frac{5}{8}[/tex] x[tex]\frac{5}{10}[/tex] = [tex]\frac{25}{80}[/tex] or [tex]\frac{5}{16}[/tex]
Therefore choice A is not a correct expression.B. [tex]\frac{4}{10}[/tex] x [tex]\frac{6}{8}[/tex] = [tex]\frac{24}{80}[/tex] or [tex]\frac{3}{10}[/tex]
Therefore, choice B is a correct expression.C. [tex]\frac{3}{5}[/tex] x [tex]\frac{1}{2}[/tex] = [tex]\frac{3}{10}[/tex]
Therefore, choice C is a correct expression.D. [tex]\frac{4}{8}[/tex] x [tex]\frac{4}{6}[/tex] = [tex]\frac{16}{64}[/tex] or [tex]\frac{1}{4}[/tex]
Therefore, choice D is not a correct expression.E. [tex]\frac{2}{5}[/tex] x [tex]\frac{3}{4}[/tex] = [tex]\frac{6}{20}[/tex] or [tex]\frac{3}{10}[/tex]
Therefore choice E is a correct expression.Find the x-intercept of the line:

In 2009, a town's population was about 9,000 residents. In 2014, the population was about 12,500 residents. Which linear model represents the town's population, p, as a function of t, the time in years after 2007
Answer:
Population function (Based on 2007) = 7,600 + 700n
Step-by-step explanation:
Given:
Population in 2009 = 9,000
Population in 2014 = 12,500
Computation:
Increase in population per year = [12,500 - 9,000] / 5
Increase in population per year = 700
Population in 2007 = 9,000 - [2 x 700]
Population in 2007 = 7,600
Population function (Based on 2007) = 7,600 + 700n
n = number of year
Answer:
p(t)=700t+7600

solve the inequality. graph the solution
Answer:
a or the first one
Step-by-step explanation:
x - 1 ≤ 6
add 1 to both sides
x ≤ 7
the ≤ is pointing <<< that way
so the line will go on the left side of seven
and since its greater than or equal to its a closed circle
HELP ASAP YALL- PLS
Answer: x = 4
Step-by-step explanation:
since it is showing us that the angles are congruent, we know that the smaller triangle is just a scaled-down version of the larger one. in other words, it is the EXACT SAME triangle, just slightly smaller.
so, i redrew them next to each other, so i could compare them easily.
i looked at the corresponding sides that were given, and realized that the side that is 10 on the larger triangle is equal to 5 on the smaller triangle. the side that is equal to 6 on the larger triangle is equal to 3 on the smaller triangle. this concludes that the smaller triangle is exactly half the size of the larger triangle!
so, i figured (using logic) that x must equal 4, simply dividing its corresponding side (with a measure of 8) in half.
hope this helps! xoxo

India has a population density of 840 people per sq. mile. If we estimate the population of the US to be 300,000,000 and the total land area to be 3,500,000 sq miles, what is our population density?
85.7 people/ sq mi
8 people/ sq mi
840 people/sq mi
300,000,000 people/ sq mi
Answer:
A. 85.7 people/ sq miStep-by-step explanation:
Population density is:
Pd = population / areaPd = 300000000 people / 3500000 sq mi = 85.7 people/ sq miCorrect option is A

Which trigonometric ratio would you use to solve for the variable??
Answer:
Sin angle = opp/hyp
Cos angle = Adj/ hyp
Tan angle = opp/adj
The opp = the base of the triangle
The hyp = w
The adj = 125
Btw....
SOH CAH TOA
SOH = Sin ( Opposite ÷ Hypotenuse)
CAH = Cos ( Adjacent ÷ Hypotenuse)
TOA = Tan ( Opposite ÷ Adjacent)

What is the missing value:
[tex]\frac{16}{1}[/tex] = [tex]\frac{x}{2\frac{1}{2} }[/tex]
Answer:
x = 40
Step-by-step explanation:
x/(2 1/2) = 16/1
x/(5/2) = 16
Multiply both sides by 5/2.
x = 16 * 5/2
x = 80/2
x = 40
Answer: x = 40
