Solve the following values for x and y :
Answer and Step-by-step explanation:
2(5x - 5) = 6x + 50
Distribute the 2 to the 5x and -5.
10x - 10 = 6x + 50
Add 10 to both sides, and subtract 6x from both sides.
4x = 60
Divide both sides by 4.
x = 15
5y + 5 = 7y - 9
Subtract 5 from both sides, and 7y from both sides.
-2y = -14
Divide both sides by -2.
y = 7

At a carnival, you spin a spinner that has four equal-sized sections, each a different color: green, yellow, red, and blue. If you land on green, you win 2 points. If you land on yellow, red, or blue, you lose 1 point. Write the expected value equation.
A= B= C=
D= E= F=
G=
Answer:
A= 4
B= 4
C= -1
D= 4
E= -1
F= 4
G= -1
Step-by-step explanation:
The expected value equation is the probability of something happening multiplied by the amount of times it happens. In this case you have four equal sized sections, so you have a one in four chance to land in any of these sections. A, B, D, and F represent the four for this one in four chance. C, E, and G represent the amount of points you get when you land on those sections, in this case -1

What is the resulting equation when the expression for y in the second equation is substituted into the first equation-3x+2y=-3
Y=4x+1
Answer:
x=-5/11, y=-9/11. (-5/11, -9/11).
Step-by-step explanation:
3x+2y=-3
y=4x+1
---------------
3x+2(4x+1)=-3
3x+8x+2=-3
11x=-3-2
11x=-5
x=-5/11
y=4(-5/11)+1
y=-20/11+11/11
y=-9/11

Step-by-step explanation:
simplify as far as possible:3x+4y+7y
Answer:
3x+4y+7y = 3x + 11 y
Step-by-step explanation:
We need to simplify the given expression i.e.
3x+4y+7y
We know that, the like terms gets add up i.e. the sum of 4y and 7y equals 11 y
So,
3x+4y+7y = 3x + 11 y
Hence, the final simplification should be 3x + 11 y.

Answer:
g(x) = [tex]2^{x}[/tex] + 4
Step-by-step explanation:
Given f(x) then f(x) + c is a vertical translation of f(x)
• If c > 0 then a shift up of c units
• If c < 0 then a shift down of c units
Here the shift is 4 units up , then
g(x) = [tex]2^{x}[/tex] + 4
Answer:
the answer is B g(x)=2^x+4

A new car is purchased for 22300 dollars. The value of the car depreciates at 10.25% per year. What will the value of the car be, to the nearest cent, after 6 years?
Answer:
$11654 approx
Step-by-step explanation:
Given data
Principal amount = 22300 dollars
Rate= 10.25%
time= 6 years
The expression for the decrease is given as
A=P(1-r)^t-----------Note the negative sign is because of the decrease
substitute
A= 22300(1-0.1025)^6
A=22300(0.8975)^6
A=22300*0.5226
A=$11653.98
Hence the new value is $11654 approx

Y+3= -5(x-1) write the equation in slope intercept form
Answer: The equation in slope-intercept form: [tex]y=-5x+2[/tex]
Step-by-step explanation:
The given equation of a line : [tex]y+3= -5(x-1)[/tex]
The equation of a line in slope -intercept form: y=mx+c, where m= slope , c=y-intercept.
We first use distributive property(a(b+c)=ab+ac) to simplify the given equation, we get
[tex]y+3=-5x+5[/tex]
Subtract 3 from both sides, we get
[tex]y=-5x-2[/tex]
Hence, the equation in slope-intercept form: [tex]y=-5x+2[/tex]

Grade 10 math help please. Please show work
Answer:
43.94?
Step-by-step explanation:
I think if you use inverse cos you should get the correct number. So, to find cos, you need to know the adjacent side and the hypotenuse. Here, the reference angle would be the person holding the kite. The distance from the person to the barn is the adjacent side, which is 18. The string of the kite, I assume, would be 25.
cos(∅) = [tex]\frac{18}{25}[/tex]
cos(∅) = 0.72
cos⁻¹(0.72) = 43.94

What is the nth term rule of the linear sequence below?
5,8,11,14,17
(btw it says the nth term not the 9th.)
9514 1404 393
Answer:
an = 5 +3(n -1)
Step-by-step explanation:
The n-th term of an arithmetic sequence is ...
an = a1 +d(n -1)
Here, you have first term a1=5 and common difference d=8-5=3, so the n-th term is ...
an = 5 +3(n -1)
_____
If you like, you can simplify this to ...
an = 5 +3n -3
an = 3n +2
Answer:
it's 3n-3
