Answer:
Step-by-step explanation:
For a solution to occur y=y so we can say
3x=2x+2 subtract 2x from each side
x=2, since y=3x
y=3(2)

The groups of values plugged into the TVM Solver of a graphing calculator will give the monthly payment for a 30-year loan for $265,000 at 5.9% interest, compounded monthly are,
N=360, 1% = 5.9; PV=-265000; PMT=; FV=0; P/Y=12; C/Y=12; PMT:END.
The correct option is C.
What is compound interest rate?Compound interest is computed as interest on the principle of an account plus any accrued interest.
Compound interest can be calculated using the following formula:
x = P (1+r/n
,where x = compound interest
P = principal (the initial deposit or loan amount)
r = annual interest rate
n = the number of compounding periods per unit of time
t = the number of time units the money is invested or borrowed for
Given:
TVM Solver of a graphing calculator will give the monthly payment for a 30-year loan for $265,000 at 5.9% interest, compounded monthly.
Then,
N: The overall amount of payments. Calculating this is simple if you multiply the P/Y by the number of years.
I%: Interest rate per year. Enter this rate as a percentage at all times!
Present Value, or PV: This is the sum of your investment or the loan.
PMT: The sum due.
Future Value (FV): This is your desired level of savings or, if you are calculating loans, your projected loan balance at maturity.
P/Y: The quantity of payment intervals per year.
C/Y: The quantity of compounding cycles each year.
N=360, 1% = 5.9; PV=-265000; PMT=; FV=0; P/Y=12; C/Y=12; PMT:END
Therefore, N=360, 1% = 5.9; PV=-265000; PMT=; FV=0; P/Y=12; C/Y=12; PMT:END.

Determine whether the lines x+ 7y= −3 and y = 7x + 25 are parallel, perpendicular, or neither. Justify your answer by showing all the needed work.
Answer:
perpendicular
Step-by-step explanation:
Rewrite the equations
y = (-1/7)x - 3/7 -- L1
y = 7x + 25 -- L2
Slope of L1 x Slope of L2 = -1/7 x 7 = -1
As a result, the two lines are perpendicular

a normal distribution has a mean of 56 and a standard deviation of 8. Find the percentage of data values that are in the given interval. Use the curve to aid you.
Answer:
12) Between 40 and 64 = 0.815
13) Between 32 and 40 = 0.0235
14) Between 56 and 64 = 0.34
15) At most 56 = 0.515
16) At least 72 = 0.025
17) At most 64 = 0.855
Explanation:
To answer this, we will convert each of the values into their standardized form to make this easier.
The standardized score for any value is the value minus the mean then divided by the standard deviation.
z = (x - μ)/σ
x = Each value
μ = Mean = 56
σ = Standard deviation = 8
12) Between 40 and 64
For 40,
z = (x - μ)/σ = (40 - 56)/8 = (-16/8) = -2
For 64
z = (x - μ)/σ = (64 - 56)/8 = (8/8) = 1
So,
Between 40 and 64 = Between -2 and 1
From the curve, noting that the central point is the mean, with standard score of 0, the lines before it move in step of 1 standard deviation towards the negative side, that is, -1, -2, etc. And the lines before the central point move towards the positive side, that is, 1, 2, 3, etc.
So,
Between -2 and 1 = 0.135 + 0.34 + 0.34 = 0.815
13) Between 32 and 40
For 32,
z = (x - μ)/σ = (32 - 56)/8 = (-24/8) = -3
For 40,
z = (x - μ)/σ = (40 - 56)/8 = (-16/8) = -2
So,
Between 32 and 40 = Between -3 and -2 = 0.0235
14) Between 56 and 64
For 56,
z = (x - μ)/σ = (56 - 56)/8 = (0/8) = 0
For 64,
z = (x - μ)/σ = (64 - 56)/8 = (8/8) = 1
Between 56 and 64 = Between 0 and 1 = 0.34
15) At most 56
For 56,
z = (x - μ)/σ = (56 - 56)/8 = (0/8) = 0
At most 56 = At most 0 = 0.0015 + 0.0235 + 0.15 + 0.34 = 0.515
All the regions before z = 0)
16) At least 72
For 72,
z = (x - μ)/σ = (72 - 56)/8 = (16/8) = 2
At least 72 = At least 2 = 0.0235 + 0.0015 = 0.025
(All the regions from z = 2 to the end)
17) At most 64
For 64,
z = (x - μ)/σ = (64 - 56)/8 = (8/8) = 1
At most 64 = At most 1 = 0.0015 + 0.0235 + 0.15 + 0.34 + 0.34 = 0.855
(All the regions before z = 1)

If c varies directly as the square root of d, and c=14, when d = 64, find c when d= 324
Answer:
c = 31.5
Step-by-step explanation:
Given c varies directly as [tex]\sqrt{d}[/tex] then the equation relating them is
c = k[tex]\sqrt{d}[/tex] ← k is the constant of variation
To find k use the condition c = 14 when d = 64, then
14 = k ×[tex]\sqrt{64}[/tex] = 8k ( divide both sides by 8 )
1.75 = k
c = 1.75[tex]\sqrt{d}[/tex] ← equation of variation
When d = 324 , then
c = 1.75 × [tex]\sqrt{324}[/tex] = 1.75 × 18 = 31.5

The members of a basketball team are selling T-shirts during spirit week. The cost is $20 for the design and $1.50 to print each T-shirt. The cost, y, to print x T-shirts is y=1.5x+20. Interpret the slope and the y-intercept.
Answer:
Slope of 1.5 means that the printing of each new t-shirt is of $1.50.
The y-intercept of 20 means that the fixed cost, that is, the cost without printing the t-shirts, only the design, is of $20.
Step-by-step explanation:
Equation of a line:
An equation of a line has the following format:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the increase in y when x increases by 1.
b is the y-intercept, which is the value of y when x = 0.
The cost, y, to print x T-shirts is y=1.5x+20.
Slope of 1.5 means that the printing of each new t-shirt is of $1.50.
The y-intercept of 20 means that the fixed cost, that is, the cost without printing the t-shirts, only the design, is of $20.
Find the value of x.

Write the equation of b with center b(-2,3) and radius 10.
Answer:
(x+2)^2+(y-3)^2=100
Step-by-step explanation:
so the equation is (x-h)^2+(y-k)^2=r^2
(h,k)=center
r^2=radius
in this case (h,k)=(-2,3)
r^2=r^2
10^2=100
(x-(-2))^2+(y-3)^2=100
