Ocsar and his little brother made up a game using coins. They flip the coin towards a cup and receive points for every one that makes it in. Oscar starts with 20 points, and his little brother starts with 18 points. Oscar gets 2 points for every successful shot, and his brother, since he is younger, gets 3 points for each successful shot. Eventually, the brother will have a tied score in the game. How many additional shots will each brother have made? How many points will they both have?
they both would have 24
they both would have 2 successful shots. they would mean that the older brother added 4 point to his score and the younger brother would have added 6 to his score

Step-by-step explanation:
Write the equation of the line that passes through the points (3,5) and (-1,1). Put
your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.
Given:
A line passes through the two points (3,5) and (-1,1).
To find:
The equation of the line in fully reduced point-slope form.
Solution:
If a line passes through two points, then the point slope form of the line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
The line passes through the two points (3,5) and (-1,1). So, the point slope form of the line is
[tex]y-5=\dfrac{1-5}{-1-3}(x-3)[/tex]
[tex]y-5=\dfrac{-4}{-4}(x-3)[/tex]
[tex]y-5=1(x-3)[/tex]
Therefore, the point slope form of the line in fully reduced form is [tex]y-5=1(x-3)[/tex], here 1 is the slope of the line.

The area of this shape is 75cm2
Find the perimeter of the shape.
x + 3
2x + 5
Answer:
42.6cm
Step-by-step explanation:
The sum total of all the sides of the shape is the perimeter of the shape. Hence;
Perimeter = x+3 + 4 + x+9 + 2x+5
Perimeter = 4x + 21
Given
Area of the figure = 75cm^2
Area = (x+3)(2x+5) + (2x+1)(6)
75 = 2x²+5x+6x+15+12x+6
75 = 2x²+23x+21
2x²+23x+21-75 = 0
2x²+23x-54 = 0
x = -23±√23²-4(2)(-75)/4
x = -23±√529+600/4
x = -12±√1129/4
x = -12+33.6/4
x = 21.6/4
x = 5.4
Recall that;
Perimeter = 4x+21
Perimeter = 4(5.4) + 21
Perimeter = 21.6+21
Perimeter = 42.6cm
Hence the perimeter is 42.6cm

Find the perimeter and area of a rectangle with length (6) and width (x + 2).
Answer:
The perimeter of a rectangle is: P = 2x+16
The area of a rectangle is: A = 6x+12.
Step-by-step explanation:
Given
The length of a rectangle = l = 6
The width of a rectangle = w = (x+2)
To determine
The perimeter of a rectangle = P
The area of a rectangle = A
Determining the Perimeter of a rectangle
The perimeter of a rectangle can be determined using the formula
P = 2(l+w)
substitute l = 6 and w = (x+2)
P = 2(6+x+2)
P = 2(8+x)
P = 2x+16
Therefore, the perimeter of a rectangle is: P = 2x+16
Determining the Area of a rectangle
The Area of a rectangle can be determined using the formula
A = lw
substitute l = 6 and w = (x+2)
A = (6)(x+2)
A = 6x+12
Therefore, the area of a rectangle is: A = 6x+12.
Solve 4x + 2 = 20 klkllk
Answer:
x = 4.5
Step-by-step explanation:
First, we can subtract 2 from 20 (20 - 2) to get 18.
Now we know that x has to be multiplied by 4 and have a product of 18.
We can divide 18 by 4 to figure out what x is.
18 ÷ 4 = 4.5
We can check our answer by solving the equation:
4(4.5) + 2 = 20
18 + 2 = 20
20 = 20

2y – 9x = 4
......................
Answer:
y=9/2x+2
Step-by-step explanation:
Answer:
x=2/9y + -4/9
Step-by-step explanation:
Solve for x:
2y−9x=4
Add -2y to both sides:
−9x+2y+−2y=4+−2y
−9x=−2y+4
Divide both sides by -9:
−9x /−9 =−2y+4 /-9
Then your answer is:
x= 2 /9 y+ −4/ 9

Simply 3x +9y + 2x
Please help me
Answer:
5x+9y
Step-by-step explanation:
Step-by-step explanation: Notice that 3x and 2x are like terms.
So we can combine them to get 5x.
Since 9y is the only y term, we leave it separate.
So our answer is 5x + 9y.
What is the equation of the line perpendicular to 2x + y = -5 and passes through the point (4, -3)? Write your answer in slope-intercept form. Show all work.
2x+y= -5 is our equation and it passes through (4, -3)
point-slope formula= y-y1= m(x-x1)
fill in your formula, but flip the slope so its perpendicular. so slope is 1/2.
y+3=1/2(x-4) when i filled the formula in, i used 4 as x1 and -3 as y1.
y+3=1/2x-2 multiply x and -4 by 1/2
y=1/2x-5 subtract 3 from both sides.
Final answer: y=1/2x-5

Answer:
x=35
Step-by-step explanation:
Alright so an isosceles triangle is a triangles that has 2 angles that have the same value and those lines tell us which angles are the ones that are the same which would be angle Q and angle R. The lines are almost pointing at those angles. All of the angles will equal 180 so we set up an equation
180=2x + 40 because Q and R have the same value we multiply the 2x by 2
now we have 180=4x+40
step 1 subtract each side by 40
140=4x
step 2 divide each side by 4
35=x

ײ+x(x+1)(x+2)+(1+x) = x²+(x+1)³
Step-by-step explanation:
ײ+x(x+1)(x+2)+(1+x) ...look that: 1+x=(x+1)
=x²+x(x+1)(x+2)+(x+1)
=x²+(x+1)(x²+2x+1)
=x²+(x+1)³
