We develop an equation for the given situation by first writing the general equation for lines,
y = mx + b
Substituting to this given the values given above,
(1990) 430 = b
(2000) 400 = m(10) + 430
The value of m from the equation in 2000 is -3. Thus, the equation of that relates the variables is,
y = -3x + 430

A square patio has an area of 136 square feet. How long is each side of the patio to the nearest tenth?
Answer:
11.7
Step-by-step explanation:
Answer:
11.7 feet
Step-by-step explanation:
Area finds the length times the width (LxW). In other words, area is how long the first side is multiplied by how wide the second side is. If A=LxW, and we know A is 136, then we know that 136=LxW. This alone isn't enough to find L and W. However, we do know that the patio is a square. Squares have equal sides, so L and W will be the same number. Basically, you need to find the number that equals 136 when it's multiplied by itself. X multiplied by X needs to be 136. You can do this easily with a calculator, if you're allowed to have one. just use the square root function on 136, and be sure to round your answer. If you're not allowed to use a calculator, it's a bit more trial-and-error. Try to see what numbers multiplied by themselves get close to 136, and narrow it down from there (ex. if 11 is too little and 12 is too much, the answer is between 11 and 12). You can also look up video tutorials for how to find a square root without a calculator, or use other study platforms. I hope this helps, and feel free to ask me any questions!! :)
The graph of y = f(x) is shown. Choose all the true statements.
−2 is a member of the domain of f.
−2 is a member of the range of f.
f(0) > 0
f(2) > 2
Answer:
−2 is a member of the domain of f.
f(0) > 0
Step-by-step explanation:
Statement 1 is TRUE. Domain value includes set of values of x of the function. -2 is plotted on the x-axis on the graph. Therefore, it is a member of domain of f.
Statement 2 is incorrect. Range includes all possible y-values of the function. On the graph, no y-value plotted is -2. Therefore, -2 is NOT a member of the range of f.
Statement 3 is TRUE.
f(0) is approximately 2.2 on the graph. i.e. at x = 0, y ≈ 2.2.
Therefore, f(0) > 0.
Statement 4 is INCORRECT.
f(2) = 1, that is at x = 2, y = 1 as seen in the graph. Therefore, f(2) is not greater than 2.

Step-by-step explanation:
P = a + b + c; solve for b
Answer:
b = P - a - c
Step-by-step explanation:
Step 1: Write equation
P = a + b + c
Step 2: Solve for b
Subtract a on both sides: P - a = b + cSubtract c on both sides: P - a - c = bRewrite: b = P - a - cThis du today I NEED HELP!!!!! IS URGENT!!!!!!!!!!!!!
Answer:
x = 8
Step-by-step explanation:
The perimeter of a body is the sum of all its sides.
Perimeter of the triangle;
hypothenuse + opposite + adjacent = x+6 + x + 3 + x + 9 = 3x + 18
Perimeter of the rectangle = x+1 + x + 4 + x + 1 + x + 4 = 4x + 10
Now,
Since their perimeter is equal;
3x + 18 = 4x + 10
3x - 4x = 10 - 18
-x = -8
x = 8

A plane flew 720 miles in 6 hours. How many miles did the plane fly in 4 hours?
Answer:
[tex]\huge\boxed{\texttt{480 miles}}[/tex]
Step-by-step explanation:
We can create a ratio here to find the constant of proportionality and use that to find how many miles the plane flew in 4 hours.
We know the plane flew 720 miles in 6 hours. We can create a ratio, represented as a fraction, in the form [tex]\frac{miles}{hours}[/tex] .
[tex]\frac{720}{6}[/tex]
We can now make another ratio where we use a variable for the miles flown in 4 hours.
[tex]\frac{x}{4}[/tex]
Since the ratios are equal, we can create an equation.
[tex]\frac{720}{6}=\frac{x}{4}[/tex]
To find the value of x, let's cross multiply.
[tex]720 \cdot 4 = 2880\\\\2880\div 6 = 480[/tex]
So the plane flew 480 miles in 4 hours.
Hope this helped!

2(x + 4) - 6 = 5x - 17
Answer:
x=6.3 :)
Step-by-step explanation:
2(x+4)-6=5x-17
2x+8-6=5x-17
2=3x-17
19=3x
19/3=6.3
Answer:
2(x+4) -6 = 5x-17
2x + 8 - 6 = 5x - 17
8 -6 + 17 = 5x - 2x
2 + 17 = 3x
19 = 3x
divide both side by the coefficient of x which is 3
19/3 = 3x/3
x = 19/3
x = 6 1/3. or 6.33

p(x)=6x-5. p(x)=13 what is x?
Answer:
x=3
Step-by-step explanation:
Answer:
x = 3
Step-by-step explanation:
p(x) = 6x - 5 but p(x) = 13
=> 6x - 5 = 13
<=> 6x = 18
<=> x = 18 : 6 =3

Jordan created a scale drawing of a rectangular room. The drawing is 8 inches long by 6 inches wide. He used a scale of 1 inch - 3 feet. What is the area, in square feet,
Answer: 144 feet
Step-by-step explanation:
Well solving for area you multiply length times wedth. So multiply 8 and 6 to get 48. Now you have to convert 48 inches into feet. So just multiply 48 times 3 to get 144.

Hank wants to add a row of tile to his kitchen wall. The space is 5.75 feet long. He plans to put a \frac {3}{4} 4 3 –foot yellow tile in the center. He'll fill the rest of the space with blue tiles that are 3 inches long. How many 3-inch blue tiles will he need?
Answer:
He will need 20 3-inch blue tiles
Step-by-step explanation:
Here, the total space to fill is a length of 5.75 ft
The tiles to place at the center has 3/4 ft which is same as 0.75 ft
The length left unfilled will be 5.75 - 0.75 = 5 ft
Now we want to know the number of 3 ft tiles needed to fill up this length;
Mathematically, we know that
1 ft = 12 inches
So 5 ft will be 5 * 12 = 60 inches
So the number of 3 inch tiles needed to fill this length will be 60/3 = 20 tiles

Write an equation for a circle given that the endpoints of the diameter are
(-8,5) and (4,-3)
Answer: (2,2)
so Using the distance formula,
d = sqrt(x2-x1)^2 +(y2-y1)^2 .
Substituting the values of x and y.
we get,
d = sqrt(-4-8)^2 +(-3-7)^2
d = 2 sqrt 61
diameter = 2*radius
= 2 sqrt 61
= 2 r
= r
= sqrt 61
r^2 = 61
midpoint of the diameter is:
Xm= 8-4 / 2
= 2
Ym = 7-3 / 2
= 2
Hence,
The center is (2,2)
