10/24, 25/607:16, 35:806 to 8, 15 to 2014/16, 35/40Step-by-step explanation:
Just as the directions tell you, multiply both parts of the ratio by the same number. Here, the equivalents we used are 1, 2, and 5 times the numbers in the reduced ratio. Your multipliers can be anything, and don't need to be positive or rational or numbers.

1. 5/12 = (5·2)/(12·2) = 10/24
5/12 = (5·5)/(12·5) = 25/60
__
2. 14:32 = (7·2):(16·2) = 7:16
7:16 = (7·5):(16·5) = 35:80

3. 3 to 4 = (3·2) to (4·2) = 6 to 8
3 to 4 = (3·5) to (4·5) = 15 to 20
__
4. 7/8 = (7·2)/(8·2) = 14/16
7/8 = (7·5)/(8·5) = 35/40
7/8 = (7·m)/(8·m) = (7m)/(8m) . . . m ≠ 0
Solve system of equations
3x+6y=18
X+3y=15
Answer:
x = - 12, y = 9
Step-by-step explanation:
Given the 2 equations
3x + 6y = 18 → (1)
x + 3y = 15 → (2)
Multiplying (2) by - 3 and adding to (1) eliminates the term in x
- 3x - 9y = - 45 → (3)
Add (1) and (3) term by term to eliminate x
- 3y = - 27 ( divide both sides by - 3 )
y = 9
Substitute y = 9 into either of the 2 equations and evaluate for x
Substituting into (2)
x + 3(9) = 15
x + 27 = 15 ( subtract 27 from both sides )
x = - 12
Solution is (- 12, 9 )
Find the difference 9/x+1 - 2x/x+1
Answer:
I think the answer is 9-2x/x+1

Answer:
1
Step-by-step explanation
Since you are given two points you can calculate the slope by use the formula Y1-Y2/X1-X2.
In this case:
Y1 = 5
Y2 = 7
X1 = 7
X2 = 9
(5-7)/(7-9) = -2/-2 = 1

Step-by-step explanation:
10 friends decided to buy a joint gift for their best friend. But as it happens, the two gave up and decided to buy her a present themselves. Thus, the remaining 8 friends had to add 50 dollars each to buy the gift.
How much did the gift cost?
Answer:
The answer is $2000
Step-by-step explanation:
8 had to give an extra $50 each.
8 x 50 = 400
400 ÷ 2 ( the two that changed their mind) = 200
Each person was to give $200
10 × 200 = 2000

What are the x-intercepts of y = 2x² + 15x + 7?
The scatterplot and table show the weekly profit in dollars earned from the sale of pastries at seven different prices. The data can be modeled by a quadratic function.
Which function best models the data?
A)y = 0.001x2 - 0.426x + 35.672
B)y = -60.4x2+ 348.1x - 334.2
C)y = 0.001x2+ 35.672
D)y = -60.4x2 - 334.2
The table is an illustration of a quadratic regression model
The function that best models the data is y = -60.4x^2 +348.1x -334.2
How to determine the function that models the data?To determine the function that models the data, we make use of a graphing calculator.
Using the graphing calculator, we have the following calculation summary
a = -60.4
b = 348.1
c = -334.2
A quadratic regression model is represented as:
y = ax^2 + bx + c
So, we have:
y = -60.4x^2 +348.1x -334.2
Hence, the function that best models the data is y = -60.4x^2 +348.1x -334.2

3(x - 1) = 2x + 9
Do this equation have one solution, many solution, or no solution?
9514 1404 393
Answer:
1 solution
Step-by-step explanation:
The coefficients of x are different on each side of the equal sign, so this equation has one solution.
_____
Additional comment
If the x-coefficients are the same on each side of the equal sign, then you need to look at the constants. If they are the same, there are an infinite number of solutions; if they are different, no solutions.
This equation simplifies to ...
3x -3 = 2x +9
x = 12 . . . . . . . . add 3-2x to both sides
The solution of expression by applying distributive property and combining like terms,
⇒ x = 12
Given that,
The mathematical expression is,
⇒ 3(x - 1) = 2x + 9
Now, simplify the expression by applying distributive property and combining like terms,
⇒ 3(x - 1) = 2x + 9
Apply distributive property,
⇒ 3x - 3 = 2x + 9
Combine like terms,
⇒ 3x - 2x = 9 + 3
Therefore, the solution of expression is,
⇒ x = 12

A parabola has focus (5,7) and directrix y=0(the X-axis). Write an equation that says point (x,y) is on the
parabola.
Answer:
Step-by-step explanation:
focus of the parabola is (2,0) and directrix is x=-2. Here,a=2.So, Equation becomes, y2=4∗2x⇒y2=8x, which is the required equation of parabola.
The equation of a parabola with the given focus and directrix is x²-10x+74=14y.
What is an equation of a parabola?A parabola refers to an equation of a curve, such that a point on the curve is equidistant from a fixed point, and a fixed line
Given that, a parabola has focus (5,7) and directrix y=0.
When the focus (h, k) of a parabola and the equation of the directrix y = c are given, the equation of the parabola is given by (x-h)²+k²-c²=2(k-c)y
Here, y=c=0
Now, (x-5)²+7²-0²=2(7-0)y
x²-10x+25+49=14y
x²-10x+74=14y
Therefore, the equation of a parabola is x²-10x+74=14y.

Step-by-step explanation:
Check if a relation is a function by looking at the x's.
No repeated x's? Then it's a function.
Repeated x's but the y is the same y both times? It's a function.
Repeated x's and different y's? NOT A FUNCTION.
