What’s the equation for this table? Use y=mx+b. HELP
Answer:
y = 2x + 12
Step-by-step explanation:
You can check this by plugging any of the values from the table into the equation. You can find the answer by finding the slope and then using that to find the y-intercept.
y2-y1/x2-x1
16-14/2-1 = 2/1 = 2. So our slope equals 2.
If we set x = 0 to find our y-intercept, and we know that we have a slope of 2 we can subtract 2 from 14 to get the y-intercept.
14-2 = 12. --> (0, 12) which is true because we know that the slope is 2.
Solve the rational equation.

Step-by-step explanation:
thats ur answer
Answer:
B. 2
Step-by-step explanation:
A 4-column table with 5 rows. Column 1 is labeled Variable with entries Total Population, Population 65 +, Population less than 15, Life expectancy at birth, Population projection 2050. Column 2 is labeled Africa with entries 967,049,000, 32,653,000 (3 percent), 400,004,000 (41 percent), 54 years, 1,932,394,000. Column 3 is labeled Asia with entries 4,052,332,000, 268,981,000 (7 percent), 1,090,690,000 (27 percent), 69 years, 5,427,360,000. Column 4 is labeled Europe with entries 735,579,000, 118,577,000 (16 percent), 114,649,000 (16 percent) 75 years, 685,007,000. Data from the P B R World Population Data Sheet.
Look at the data above. Provide an explanation for Europe’s projected population decrease by the year 2050.
Answer:
Europe is a continent that for some time now has had a problem with its population. The reason for it is that Europe's birthrates have been very low, not enough even for just maintaining the same number of population, as the birthrates are below 2 children per wife all countries apart from three.
The only three countries where the average is more than 2 children per women are Ireland, Albania, and Kosovo, all of which are small countries with small populations.
Also the life expectancy in Europe is relatively high, so the older population is constantly increasing, thus resulting in an aging population.
Of course the elderly people will eventually pass away, and with the smaller and smaller number of youngsters and very low birthrates the continent will constantly lose more and more population.
Answer:
The percentage of people over the age of 65 and under the age of 15 in Europe is currently the same at 16% each. Therefore, the majority of the population is between the ages of 16 and 64. In forty years from now, in 2050, a greater percentage of the population will be over the age of 65. Europe also has a relatively long life expectancy of 75 years. This, combined with a low birth rate means that by 2050 Europe’s population will actually be less than it is today.

Mike has a loan of $36,320. This loan has a simple interest rate of 6% per year. What is the
amount of interest that will be charged on this loan at the end of the first year?
Answer:
$2,179.2Step-by-step explanation:
Given;
Loan = $36,320 (Principal)
Rate R = 6% = 0.06
Time T = 1year
Required
Interest that will be charged on this loan at the end of the first year
Using the formula for calculating simple interest as;
SI = PRT/100
SI = 36,320 * 6 * 1/100
SI = 0.06 * 36,320
SI = $2,179.2
Hence the amount of interest that will be charged on this loan at the end of the first year is $2,179.2
Its Just an exponent Activity

What is the Value of X?
Is 2/9 equivalent to 1:5 ?
Answer:
No it is not
Now can u help me with my most recent question plssss
I will be giving brainleist on it
Answer: no 2/9 id not equivalent to 1.5
Step-by-step explanation: first to get the percentage of 2/9 divide 10 by 9 which equals 1 then you multiply 2 to the awnser which equals 2. which means that 2/9ths is equivalent to 20 percent. now twenty percent or .20 is the equivqlent percent to 2/9 so no 2/9 is not equivalent to 1.5

Answer:
x = 3
y = 17
or (3,17)
Step-by-step explanation:
y = 4x + 5
y = -1/3x - 8
4x + 5 = -1/3x - 8
4x = -1/3x - 13
12x = -x - 39
13x = -39
x = 3
y = 4(3) + 5
y = 12 + 5
y = 17
If you are offered one slice from a round pizza and the slice must have a perimeter of 36 inches, what diameter pizza will reward you with the largest slice
Answer:
A diameter of 16 inches will give the largest slice
Step-by-step explanation:
Step 1: Statement of optimization
largest slice of pizza = maximum area of the sector
Step 2: Formula for area and perimeter of sector:
Area of sector, A = 1/2r²θ
Perimeter of sector, P = 2r + rθ
Step 3: Determining the constraint
The perimeter, P, must be equal to 36 inches ie. 2r + rθ = 32
Therefore, θ = 32 -2r/r
Substituting θ in the formula for area;
A = 1/2r²(32 -2r/r)
A = -2r² + 16r
The domain of A(r) = 0 < r < 16
Step 4: Determine the maximum of object function
Critical point of A(r) , A'(r) = - 2r + 16
when A' = 0
r = -16/-2
r = 8
since, diameter, d = 2r,
Therefore, a diameter of 16 inches will give the largest slice
