a. They intercepts are the same.
b. The function () - 5 has a greater rate
of change
c. They are parallel lines:
d. The graph of the function(x) is translated
down 5 units to produce fix) - 5.
Answer:
c, d
Step-by-step explanation:
If f(x) = x, then f(x) - 5 = x - 5.
The two functions in slope-intercept form (y = mx+ b) are:
[1] y = x and [2] y = x - 5
In equation [1], the slope is 1 and the y-intercept is 0.
In equation [2], the slope is 1 and the y-intercept is -5.
a. The y-intercepts are not the same. 0 ≠ -5
b. The rates of change, or the slopes, are the same, neither are greater than the other. 1 = 1
c. They are parallel lines. Lines are parallel when they have the same slope. 1 = 1.
d. The (-5) indicates that the new function is translated down (-) by 5 units (5) from the parent function f(x) = x.
c and d are correct.
Bevo has $5000 to invest. Bank A offers a savings account that has an APR of 1.15% and compounds monthly. Which equation will determine how much money Bevo will have in his account after 9 years?
The equation [tex]A=5000(1.000958333)^{108}[/tex] will determine how much money Bevo will have in his account after 9 years
Step-by-step explanation:
The formula for compound interest, including principal sum is
[tex]A=P(1+\frac{r}{n})^{nt}[/tex] , where:
A is the future value of the investment/loan, including interestP is the principal investment amount (the initial deposit or loan amount)r is the annual interest rate (decimal)n is the number of times that interest is compounded per unit tt is the time the money is invested or borrowed forBevo has $5000 to invest. Bank A offers a savings account that has an APR of 1.15% and compounds monthly
We need to find Which equation will determine how much money Bevo will have in his account after 9 years
Because there is no choices we will write the equation
∵ Bevo has $5000 to invest
∴ P = 5000
∵ Bank A offers a savings account that has an APR of 1.15%
and compounds monthly
∴ r = 1.15% = 1.15 ÷ 100 = 0.0115
∴ n = 12 ⇒ compounds monthly
∵ t = 9
- Substitute all of theses values in the formula below
∵ [tex]A=P(1+\frac{r}{n})^{nt}[/tex]
∴ [tex]A=5000(1+\frac{0.0115}{12})^{(12)(9)}[/tex]
∴ [tex]A=5000(1.000958333)^{108}[/tex]

The equation to find out how much Bevo will have in his account after 9 years by investing $5000 in a saving account at Bank A which offers an APR of 1.15% compounding monthly is given by the future value formula of compound interest: FV = P(1 + r/n)^(nt). By plugging the values into this formula, Bevo can determine his future balance.
Explanation:The subject of this question is about understanding compound interest. Specifically, it is about interpreting how Bevo's financial investment would grow over a certain period at a specific rate of interest in a savings account. The equation to calculate the future value (FV) of Bevo's investment, compounded monthly, is given by the compound interest formula:
FV = P(1 + r/n)^(nt)
Where:
P is the principal amount (the initial amount of money Bevo has to invest, in this case $5000).r is the annual interest rate in decimal form (the APR divided by 100, for Bank A this would be 1.15/100 = 0.0115).n is the number of times that interest is compounded per unit t, in this case, this value is 12 (as it is compounded monthly).t is the time the money is invested for in years (specified in the question as 9 years).This gives a better understanding of how savings accounts and compounded interest work.

find the coordinates of point P along the directed line segment AB so that AP to PB is the given ratio. A(-4,-8), B(0,0) ; 3 to 1
To find the coordinates of point P along the directed line segment AB so that AP to PB is in the ratio 3 to 1, we use the section formula. Substituting the values into the formula, we find that the coordinates of point P are (-1, -2).
Explanation:To find the coordinates of point P along the directed line segment AB so that AP to PB is in the ratio 3 to 1, we can use the concept of section formula.
The section formula states that if we have two points A(x1, y1) and B(x2, y2), and we want to find a point P along the line segment AB such that AP to PB is in the ratio m to n, then the coordinates of P can be found using the following formulas:
x = (mx2 + nx1) / (m + n)
y = (my2 + ny1) / (m + n)
In this case, A(-4, -8) and B(0, 0).
Let's substitute the values into the formula:
x = (3 * 0 + 1 * -4) / (3 + 1) = -4/4 = -1
y = (3 * 0 + 1 * -8) / (3 + 1) = -8/4 = -2
Therefore, the coordinates of point P are (-1, -2).
Final answer:
To find point P on line segment AB where AP:PB = 3:1, we use section formula to get P's coordinates as (-1,-2). This method applies interpolation of the endpoints' coordinates, A(-4,-8) and B(0,0), by their respective weights in the given ratio.
Explanation:
To find the coordinates of point P on the directed line segment AB such that the ratio of AP to PB is 3 to 1, we can use the section formula which combines the x and y coordinates of A and B weighted by the given ratio, since P divides AB internally in the ratio 3:1.
The coordinates of A are (-4, -8) and the coordinates of B are (0, 0). Using the section formula, we can find the coordinates of P as follows:
Let x and y be the coordinates of P.
The x-coordinate of P is given by ((3 * 0) + (1 * (-4))) / (3 + 1) = -1.
The y-coordinate of P is given by ((3 * 0) + (1 * (-8))) / (3 + 1) = -2.
Therefore, the coordinates of P are (-1, -2).
This process involves interpolation of the given points in the specific ratio to find the required coordinates.

Now, The ratio of X's to O's is 12 : 9.
Now, we have to determine another ration for X's to O's.
The image will help us to do that.
There are 12 numbers of X and that can be broken into 3 sets of X with 4 X in each set. Hence, 12 = 3 × 4
Again, there are 9 numbers of O and that can be broken into 3 sets of O with 3 O in each set. Hence, 9 = 3 × 3
Therefore, the ratio of X's to O's is 12 : 9 ≡ (3 × 4) : (3 × 3) ≡ 4 : 3
{Cancelling 3 from each term} (Answer)
Answer:
The answer is 4 over 3.

Answer:
this answer is. _48 am I right
the factored form of the expression [tex]\(3x^2 + 7x - 6\) is \((3x - 2)(x + 3)\).[/tex]
To factor the expression [tex]\(3x^2 + 7x - 6\),[/tex] we need to find two numbers that multiply to give [tex]\(3 \times (-6) = -18\)[/tex] and add to give the middle coefficient, (7)

Find the 15th term of the geometric sequence 3, -6, 12, ...
Answer:
49152
Step-by-step explanation:
To find the 15th term of the geometric sequence 3, -6, 12, ..., we identify the common ratio as -2 and use the formula for the nth term of a geometric sequence. By calculating 3 * (-2)^14, we find that the 15th term is 49152.
Explanation:To find the 15th term of the geometric sequence 3, -6, 12, ... we first need to determine the common ratio. By dividing the second term by the first term, we find that the common ratio is -2.
Formula for the nth term of a geometric sequence:
an = a1 × r(n-1), where an is the nth term, a1 is the first term, r is the common ratio, and n is the term number.
Finding the 15th term:
Plugging in the values, we get: a15 = 3 × (-2)(15-1) = 3 × (-2)14. Since (-2)14 is positive (because any even power of a negative number is positive), the 15th term will be positive. Calculating the value, a15 = 3 × 16384 = 49152.
Therefore, the 15th term of the geometric sequence is 49152.

Manny can complete a sales route in 7 hours. Jane can do the same job in 3hours. How long will it take them to the job together
Answer:
Step-by-step explanation:
1/7x+1/3x=1
3/21x+7/21x=1
10/21x=1
x=21/10 hour or 2 hours and 1 minute
Final answer:
Manny and Jane will take approximately 2.1 hours to complete the job together.
Explanation:
To find out how long it will take Manny and Jane to complete the job together, we need to determine their combined rate of work. Manny can complete the job in 7 hours, so his work rate is 1/7 of the job per hour. Jane can complete the job in 3 hours, so her work rate is 1/3 of the job per hour. To find their combined rate, we add their individual rates: 1/7 + 1/3 = 3/21 + 7/21 = 10/21.
Since their combined work rate is 10/21 of the job per hour, it will take them 21/10 hours to complete the job together. Simplifying this fraction, we get 2.1 hours. Therefore, it will take Manny and Jane approximately 2.1 hours to complete the job together.
