Answer: By finding the differences between the y-values, we can determine the degree of the model for the data.
If the first difference is the same value, the model will be linear.
If the second difference is the same value, the model will be quadratic.

Find the solution of the system of equations.
4x – 5y = 46
-4x – 4y = 8
Answer:
(4,-6) or x=4 and y= -6
Step-by-step explanation:
Answer:
x = 4 ; y= -6
Step-by-step explanation:
-9y = 54
y = -6
4x +30 = 46
4x = 16
x = 4
What is the solution to the equation?
Answer:
Step-by-step explanation:
[tex]\sqrt[3]{x+4}+\sqrt[3]{2x +8}=0\\\\\sqrt[3]{x+4}= -\sqrt[3]{2x + 8}\\\\(x +4)^{\frac{1}{3}}=-(2x+8)^{\frac{1}{3}}\\\\[/tex]
Take cube,
[tex][(x+4)^{\frac{1}{3}}]^{3} =- [(2x +8)^{\frac{1}{3}}^{3}]\\\\(x+4)^{3*\frac{1}{3}}=-(2x + 8)^{3*\frac{1}{3}}\\\\[/tex]
x + 4 = - (2x + 8)
x +4 = 2x *(-1) + 8 *(-1)
x+ 4 = -2x - 8
x +2x+4 = - 8
3x + 4 = - 8
3x = - 8 -4
3x = -12
x = -12/3
x = -4

The distance between Franklin City and Williamsville on a map is 3.2 inches. If the scale of the map is 1 inch = 15 miles, how many miles apart are the two cities?
Answer: 48 miles
Step-by-step explanation:
From the question, the distance between Franklin City and Williamsville on a map is 3.2 inches and the scale of the map is 1 inch = 15 miles.
The distance between the cities will be to multiply 3.2 by 15 to get the number of miles since 1 inch = 15 miles. This will be:
= 3.2 × 15 miles.
= 48 miles
The distance between Franklin City and Williamsville is 48 miles.
Answer:
48 Miles

Darrens garden is 4 4/6 feet long. Zanique’s garden is 2 1/3 shorter. Find the length of Zanique’s garden.
4 - 2 = 2
If you take 3 and add 3, you get 6, and if you take 1 and add 1 you get 2, so 2/6.
4/6 - 2/6 = 0.33333333333
So I'd say about 2.3333333333 is the length of Zanique's garden, in a fraction... um... 233333333333/10000000000

Sum of exterior angles of a polygon is 360°#8
2x + 2(64°) + 36° + 48° = 360°2x + 212° = 360°2x = 360° - 212°2x = 148°x = 74°#9
x + 73° + 109° + 90° = 360°x + 272° = 360°x = 360° - 272°x = 88°Simplify (8.3) 2.10.(6-1)

Did this help?The lengths of the sides of a triangle are given below. Classify the triangle as acute, obtuse, or right.
13, 5, 12
A. Acute Triangle
B. Obtuse Triangle
C. Right Triangle
Answer:
C. Right TriangleStep-by-step explanation:
Verify with Pythagorean:
13² = 1695² + 12² = 25 + 144 = 169169 = 169We see the squares are equal, so this is a right triangle.
Correct choice is C
Rick bought a car for $17,500. Each year, the car's value decreases by 20%. At this rate, what can Rick expect the value of his car to be in 6 years? *
$1.12
$15,502.24
$4,587.52
$17,380.00
Answer:
His car would be worth $15,502.24
Step-by-step explanation:
20% of 17,500 is 350. 350 x 6 = 2,100. 17,500 - 2,100 = 15,400. But that is not an answer choice so be go to the closest number which is $15,502.24
19. If 4 + 2(3x - 4) = 8, then 4x -4 =
4
8
6
2
Answer:
4
Step-by-step explanation:
First, solve for x:
4 + 2(3x - 4) = 8
4 + 6x - 8 = 8
6x = 12
x = 2
Now, plug x into 4x - 4:
4(2) - 4 => 8 - 4 = 4

Isabella opened a savings account and deposited $25,000.00. The account earns 20% interest, compounded annually. If she wants to use the money to buy a new car in 2 years, how much will she be able to spend on the car?
Answer:
$11,000
Step-by-step explanation:
1st year the account earned 20% from $25,000 = $5,000 | total = $30,000
2nd year the account earned 20% from $30,000 = $6,000
by adding the earnings of 2 years, she will be able to spend $5,000 + $6,000 = $11,000

Place the circles in order from the circle with the SMALLEST area to the circle with the LARGEST area.
Answer:
Smallest to largest:
The circle with a diameter of 19
The circle with a circumference of 87.92
The circle with the area of 1,040.09
The circle with the radius of 27
Step-by-step explanation:
-The formula for the area is pi x r^2
-The diameter is double the radius, meaning divide it by 2 to get the radius.
-The formula for a circumference is 2 x pi x r meaning, do the reverse to get the radius. (87.92 divided by pi and then by 2 gives you the radius.)
-pi is equal to 3.14
