Answer:
the area of the actual floor is 784 ft² and the ratio is (1 cm²) ÷ (16 ft²). The same would be relevant
Step-by-step explanation:
The computation of the area and the ratio of the area is shown below:
The ratio of the drawing area to the actual area is
= ((1 cm) ÷ (4 ft))²
= (1 cm²) ÷ (16 ft²)
Now the actual floor area is
(16 ft²) ÷ (1 cm²) = actual area ÷ (49 cm²)
= (16 ft²) × 49 ÷ 1
= 784 ft²
hence, the area of the actual floor is 784 ft² and the ratio is (1 cm²) ÷ (16 ft²). The same would be relevant

For Number one: -xy + 2x = 20, x = 5
To solve this, all we need to do is plugin 5 for every place we have x. So...
- (5)y + 2(5) = 20
-5y + 10 = 20
-5y = 10
y = -2
For number two: 4x - 3y - 10 = 1, x = -1
To solve this, we need to plugin -1 for all of the x variables. So...
4 (-1) - 3y - 10 = 1
-4 - 3y - 10 = 1
-14 - 3y = 1
-3y = 15
y = -5
For number three: 5x + 7y = -1, x = 4
We need to plugin -4 for all of the x variables. So...
5 (4) + 7y = -1
20 + 7y = -1
7y = -21
y = -3
For number four: x = 6 + xy, x = -3
Same as the other ones, just plugin -3 for all of the x variables. So...
-3 = 6 + (-3)y
-3 = 6 - 3y
-9 = -3y
3 = y

Kelly has $100 she received for her birthday She saves $10 each week from doing chores Which function can be used to find t the amount of money Kelly will have saved
Answer:
$620 every year
Step-by-step explanation:
Since the question didn't specify how long she would have to save for, let's just assume that it's one year. There are 52 weeks in a year which is $520, and on her birthday she would have an extra $100, so every year she saves $620 in total.

What is the slope of the line RS that contains the points R(-2, -3), S(3, -5)
HELP ASAP
Answer:
[tex]slope = \dfrac{-2}{5}[/tex]
Step-by-step explanation:
The slope of a line passing through points , [tex] (x_1,y_1) [/tex] and [tex] (x_2,y_2) [/tex] is ,
[tex]\implies slope = \dfrac{y_2-y_1}{x_2-x_1}[/tex]
Using this we have ,[tex]\implies slope = \dfrac{y_2-y_1}{x_2-x_1}\\\\\implies slope = \dfrac{-5+3}{3+2}\\\\\implies \boxed{\boxed{slope = \dfrac{-2}{5}}}[/tex]

solve for x
2 + x^2 = 18
Answer:
16
Step-by-step explanation:
Answer:
4 and -4
Step-by-step explanation:
To solve, just isolate x
2+x^2=18
subtract both sides of the equation by 2
x^2=16
find the square root of 16
(remember, no matter if a number is positive or negative, if it is squared, it automatically becomes positive)
to get:
x=4
and
x= -4

Answer:
x=4 and y=3
Step-by-step explanation:
Ah Algebra...
2x-3y=-1
y=x-1
Let's solve your system by substitution.
2x−3y=−1; y=x−1
Rewrite equations:
y=x−1;2x−3y=−1
Step: Solve
y= x−1
Step: Substitute x−1 for y in 2x−3y=−1:
2x−3y=−1
2x−3(x−1)=−1
−x+3=−1(Simplify both sides of the equation)
−x+3+−3=−1+−3(Add -3 to both sides)
−x=−4−x−1=−4−1
(Divide both sides by -1)
x=4
Step: Substitute4forxiny=x−1:
y=x−1
y=4−1
y=3(Simplify both sides of the equation)
Answer:
x=4 and y=3
Hope this helps :)
Stay Cold,
Brook
Answer:
(4,3)
Step-by-step explanation:
Being that the y variable is isolated in the second equation, the other side of that equation can be substituted for y in the first equation.
[tex]2x - 3(x - 1) = - 1[/tex]
Now simplify for x.
[tex]2x - 3x + 3 = - 1 \\ - x = - 4 \\ x = 4[/tex]
Now with that, insert the x value in for x in the second equation.
[tex]y = (4) - 1 \\ y = 3[/tex]
Now the correct answer is (4,3)
5x+2y=-10

Find an equation for the perpendicular bisector of the line segment whose endpoints
are (3, 1) and (-9, -5).
Help plz
Answer:
y= -2x -8
Step-by-step explanation:
I will be writing the equation of the perpendicular bisector in the slope-intercept form which is y=mx +c, where m is the gradient and c is the y-intercept.
A perpendicular bisector is a line that cuts through the other line perpendicularly (at 90°) and into 2 equal parts (and thus passes through the midpoint of the line).
Let's find the gradient of the given line.
[tex]\boxed{gradient = \frac{y1 -y 2}{x1 - x2} }[/tex]
Gradient of given line
[tex] = \frac{1 - ( - 5)}{3 - ( - 9)} [/tex]
[tex] = \frac{1 + 5}{3 + 9} [/tex]
[tex] = \frac{6}{12} [/tex]
[tex] = \frac{1}{2} [/tex]
The product of the gradients of 2 perpendicular lines is -1.
(½)(gradient of perpendicular bisector)= -1
Gradient of perpendicular bisector
= -1 ÷(½)
= -1(2)
= -2
Substitute m= -2 into the equation:
y= -2x +c
To find the value of c, we need to substitute a pair of coordinates that the line passes through into the equation. Since the perpendicular bisector passes through the midpoint of the given line, let's find the coordinates of the midpoint.
[tex]\boxed{midpoint = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2}) }[/tex]
Midpoint of given line
[tex] = ( \frac{3 - 9}{2} , \frac{1 - 5}{2} )[/tex]
[tex] = ( \frac{ - 6}{2} , \frac{ - 4}{2} )[/tex]
[tex] = ( - 3 , - 2)[/tex]
Substituting (-3, -2) into the equation:
-2= -2(-3) +c
-2= 6 +c
c= -2 -6 (-6 on both sides)
c= -8
Thus, the equation of the perpendicular bisector is y= -2x -8.

Answer:
The perimeter is 206.
Step-by-step explanation:
When given the area, height and side of the parallelogram, you would use the formula to find the perimeter: P=2a+2*A /h. a = side of the parallelogram, A = area, and h = height. When you plug in everything, you will get 206.
