Step-by-step explanation:
7x - 4(4x +2) = -8
7x - 16x -8 = -8
-9x = 0
x = 0
y = 2
Answer:
(0,2)
Step-by-step explanation:
7x - 4(4x + 2) = -8
7x - 16x - 8 = -8
-9x = -8 = -8
-9x = 0
x = 0
y = 4(0) + 2
y = 2
A diamond ring increases in value at a rate of 5% per year. If the ring was purchased for $1200, which equation would calculate how much will it be worth in 30 years?
Would it be
A - y = 1200(1+.05)^30
B - y = 30(1+.05)^1200
C - y = .05(1+1200)^30
Answer:
A - y = 1200(1+.05)^30
Step-by-step explanation:
In this case, you need to calculate the future value and the formula to calculate that is:
FV=PV*(1+r)^n
FV=future value
PV=present value
r=rate
n=number of periods of time
The present value would be the price of the ring which is $1200. The rate is 5% per year and the number of periods of time is 30 years since you need to find the ring's worth in 30 years. Now, you can replace the values on the formula:
FV=1200*(1+0.05)^30
According to this, the answer is that the equation to calculate how much will it be worth in 30 years is: y = 1200(1+.05)^30.

Statements are (underlined) and reasons are (bolded).
It is given that (<W) and (<Y) are both right angles, therefore, they must be congruent since they have the same angle measures.
<W = <Y definition of right angles
Moreover, it is given that (VX) and (ZX) are congruent.
VX = ZX given
Finally, it is given that (x) is the midpoint of (WY). Therefore, (WX) is congruent to (XY), and therefore, they are congruent.
WX = XY definition of midpoint
Thus, triangle (YWX) is congruent to (ZYX) by the following rule, side-angle-side, also known as (SAS).
YWX = ZYX SAS
When two sides and an angle are congruent between two or more triangles, then those triangles must be congruent.
A truck was purchased for $25,000 in 2020 and each year its value decreases by 7%. How much will the truck be worth in
2026?
Answer:
$3787.5
Step-by-step explanation:
Given data
Cost price= $25,000
Rate of decrease= 7%
Time= 2020-2026= 26 years
Let us apply the formula
A= P(1-r)^t
substitute
A= 25000(1-0.07)^26
A=25000(0.93)^26
A= 25000*0.1515
A= $3787.5
Hence the worth will be $3787.5
Find the lowest common denominator for the following fractions.

Which statement BEST describes why the exponential function exceeds the linear function?
A) The exponential function has no negative y values.
B) As exponential functions will always exceed a linear function.
C) The exponential function has a lower initial value than the linear function.
D) The linear function has a higher initial value than the exponential function.
Answer:
A
Step-by-step explanation:
A is correct. The graph of the basic exponential function neither touches nor crosses the x-axis, whereas a linear function does cross over and can be negative for some inputs.

How many portraits would Jim paint in 9 hours if he paints 2 portraits every 4 minutes?
Answer:
270 portraits in 9 hours
Step-by-step explanation:
2 every 4 minutes
60/4 = 15 (4 minute intervals in one hour)
15 x 2 = 30 portraits per hour
9 x 30 = 270
Total 2 mins In 1h
60/2=30Total 2mins In 9h
30(9)270Total protraits=270

20. in an apple orcherd in 2015,
25% of the trees produced less than 1500 apples throughout the year.
50% of the trees produced less than 2250 appies in the year.
The interquartie range of the number of apples produced by all the trees in the
orchard was 1150
The range of the number of apples produced was 2350.
The lowest number of apples produced by a tree in the orchard was 750.
(a) Show this informabon in a box plot.
(3)
Answer:
5-number summary is:
Minimum = 750Maximum = minimum + range = 750 + 2350 = 3100Median = 2250Q1 = 1500Q3 = Q1 + IQR = 1500 + 1150 = 2650The numbers are added to the box plot.

Solve the equation sin^2x= 3 cos^2x.
The value of x that satisfies the equation if x lies in the second quadrant is what degrees?
The value of x that satisfies the equation if x lies in the third quadrant is what degrees?
Step-by-step explanation:
sin^2(x)= 3 cos^2(x)
Subtract sin^2(x) on both sides
0=3cos^2(x)-sin^2(x)
By Pythagorean Identity sin^2(x)+cos^2(x)=1, we can replace cos^2(x) with 1-sin^2(x)
0=3(1-sin^2(x))-sin^2(x)
Distribute
0=3-3sin^2(x)-sin^2(x)
Combine like terms
0=3-4sin^2(x)
Add 4sin^2(x) on both sides
4sin^2(x)=3
Divide both sides by 4
sin^2(x)=3/4
Take the square root of both sides
sin(x)=+ or - sqrt(3/4)
sin(x)=+ or - sqrt(3)/sqrt(4)
sin(x)=+ or - sqrt(3)/2
This happens on the unit circle at
60 degrees
120 degrees
240 degrees
300 degrees
If we go around and around again forwards or backwards, we get the infinitely many other solutions including the one's already stated in the following solution sets
(60 +360n) degrees
(120 +360n)degrees
(240 +360n)degrees
(300 +360n)degrees
where n is an integer
x is 120 degrees or (120+360n) degrees in the second quadrant. I didn't know if you were just looking for solutions in the first nonnegative cycle of the unit circle or not.
240 degree one or the (240+360n) degrees terminates in the third.

Which is greater, -9/20 or -0.5?
Answer and Step-by-step explanation:
If we put [tex]-\frac{9}{20}[/tex] into decimal form, we get -0.45.
-0.45 is greater than -0.5, so,
[tex]-\frac{9}{20}[/tex] is greater than -0.5.
