Answer:
x=2 and y=5
Step-by-step explanation:
Steps:
I will solve your system by substitution.
x=y−3;2x+y=9
Step: Solve x = y − 3 for x:
Step: Substitute y − 3 for x in 2x + y = 9:
2x+y=9
2(y−3)+y=9
3y−6=9(Simplify both sides of the equation)
3y−6+6=9+6(Add 6 to both sides)
3y=15
3y/3=15/3 (Divide both sides by 3)
y=5
Step: Substitute 5 for y in x = y − 3 :
x=y−3
x=5−3
x=2(Simplify both sides of the equation)
Answer:
x=2 and y=5
Answer:
x = 2 y = 5
Step-by-step explanation:
Since we know that
x = y - 3
We can insert that into the equation above:
2(y-3) + y = 9
After having this equation, we can start by multiplying the numbers/variables in the parenthesis by 2.
2y - 6 + y = 9
Then add the common multiples (2y and y)
That makes:
3y - 6 = 9
We need to get 3y on a side by itself, so to do this, we can add 6 to (-6) and (9)
That makes:
3y = 15
Divide the 3 by 3 and 15 to get the y on its own:
y = 5
Now we need to find x, and to do this we can insert y into the equation:
2x + 5 = 9
Now subtract the 5 from the (5) and (9) and you'll get
2x = 4
Then you divide the 2 on both sides and get
x = 2
You can check your work by inserting x and y into the equation
2(2) + 4 = 9
Sorry for this super long explanation, and hope this helps

What is the solution to the equation x÷8−6=3?
A. x=1
B. x=24
C. x=48
D. x=72
30 POINTS TO THE RIGHT ANSWER AND BEST EXPLANTION.
Answer: D. x=72
Step-by-step explanation:
With the equation x/8-6=3 we can start solving by first moving the "-6"
x/8-6(+6)=3(+6)
x/8=9 <-- Rewrite equation after adding "6" to both sides
x/8(*8)=9(*8) <--- Multiply both sides by 8
x=72 <-- After multiplying, solution is found
g(x) = –2x – 4, fild g(6).

write an equation in pointslope form for the line through the given point through the given line (8, -3);m= -1/4
Answer:
y + 3 = - [tex]\frac{1}{4}[/tex](x - 8)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = - [tex]\frac{1}{4}[/tex] and (a, b ) = (8, - 3 ), then
y - (- 3) = - [tex]\frac{1}{4}[/tex](x - 8) , that is
y + 3 = - [tex]\frac{1}{4}[/tex](x - 8)
Lina works at shake shack which pays $9.25 an hour and the state takes 15% out of her salary for income taxes. She works 15 hours a week after school and on weekends for 5 weeks. How much is her paycheck a month?
Answer:
Lina should make $471.75 a month.
Step-by-step explanation:
If Lina makes $9.25 an hour and she works for 15 hours a week then you multiply those two numbers together. The resulting number is $555. Then you'll multiply that by .15 to find 15% of that number which is 83.25. After, you'll subtract that from $555, which gives you $471.75.

9514 1404 393
Answer:
sin(θ) = -√2/2
tan(θ) = -1
Step-by-step explanation:
The reference angle is arccos(√2/2) = 45°. The sine has the same magnitude, so the tangent (ratio of sine to cosine) has a magnitude of 1.
The angle is given as a 4th-quadrant angle. Both the sine and tangent are negative in the 4th quadrant.
sin(θ) = -√2/2
tan(θ) = -1
__
In the attachment, the angle of interest is 315° (7π/4). The given unit-circle coordinates are ...
(x, y) = (cos(θ), sin(θ))
tan(θ) = y/x
Answer:
sin(θ) = -√2/2
tan(θ) = -1

the following cylinder has a volume of 55pi cubic units and a height of 5 units. the cone has the same base area and height, and it has a slant height of 6 units. what is the volume of the cone?
Question:A cone and a cylinder have the same base area. They also have the same curved surface area. If the height of the cylinder is 3m, then the slant height of the cone (in m) is
Answer:
Given the radius of cylinder and cone are the same because there base areas are same.
Curved surface of cylinder = curved surface area of the cone
∴2πrh=πrl
∴l=2h
Given, height of cylinder =3 cm
Therefore, slant height of cone =6 cm
The volume of the cone is 22π.
How to calculate the volume?Volume of a cylinder = πr²h
55π = πr²(5)
55π = 5πr²
r² = 55π/5π
r² = ✓11
r = 3.3
The volume of the cone will be:
= 1/3πr²h
= 1/3 × π × 3.3² × 6
= 1/3 × 11 × 6 × π
= 22π

A store pays $120 for a television. The store sells the television for $300. What is the percent of the markup
Answer: 150%
Step-by-step explanation:
A store buys a television for $120.
The store then sells the television for $300.
The makeup is the amount they increased the cost price by to get to the selling price.
= 300 - 120
= $180
In percentage terms it is:
= 180/120 * 100%
= 150%
