The solution of system of equations y=x-1 , 2x+y=8 are x=3 and y=2 which we get by substitution method.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given system of equations are
y=x-1 ...(1)
2x+y=8...(2)
By using substitution method we solve the value of x and y.
Substitute y value in equation (2)
2x+x-1=8
Combine the like terms
3x-1=8
Add 1 on both sides
3x=9
Divide both sides by 3
x=3
Now plug in x value in y equation.
y=3-1
y=2
Hence, the solution of system of equations y=x-1 , 2x+y=8 are x=3 and y=2 which we get by substitution method.

Esha is seeking to invest for college. She selects an account with a compound interest rate of 2% per year. If she initially deposits $7,000, then how much will her investment be worth at the end of 5 years?
Answer:
$7700
Step-by-step explanation:
Given data
Rate= 2%
Principal= $7000
Time= 5 years
The simple interest expression is
A=P(1+rt)
substitute
A=7000(1+0.02*5)
A=7000(1+0.1)
A=7000*1.1
A=7700
Hence the amount is $7700

Help please, it's for a test due at 11:30 est; Determine if (x-6) is a factor of f(x)=2x^4-3x^3+4x-3. Explain.
Answer:
if we get 0, when we plug the value of f(x) as 6 in f(x) then (x-6) is a factor of f(x)
f(x) = 2x⁴ - 3x³ + 4x - 3f(6) = 2×6⁴ - 3×6³ + 4×6 - 3f(6) = 2592 - 638 + 24 - 3f(6) = 2616 - 641f(6) = 1975f(6) is not equal to 0
then (x-6) is not a factor of f(x) = 2x^4-3x^3+4x-3

Convert degrees to radians
Show all the work
2. 45
3. 90
Answer:
[tex]\frac{\pi }{4}[/tex] and [tex]\frac{\pi }{2}[/tex]
Step-by-step explanation:
To convert from degrees to radians
radian measure = degree measure × [tex]\frac{\pi }{180}[/tex] , then
(2)
radian measure = 45 × [tex]\frac{\pi }{180}[/tex] ( cancel 45 and 180 )
= [tex]\frac{\pi }{4}[/tex]
(3)
radian measure = 90 × [tex]\frac{\pi }{180}[/tex] ( cancel 90 and 180 )
= [tex]\frac{\pi }{2}[/tex]

Step-by-step explanation:
6×10 obv + area of circle pi(r^2) and half that for a semi cirxle
Answer:
9 π^2
Step-by-step explanation:
Let's just fined the area of the rectangle: Area= 2lw = A=60
Now, we know the diameter of the Spehre which is 10 -2 -2 = 6, the radius is half of that = 3
A=πr2 = A≈28.27
add A≈28.27 + 60 = 88.27 = 9 π^2≈88.82643
