One day, Alonso decided to keep a record of the time he spent walking and the distance he walked. Which of the following are tru

e about the data shown? Check all that apply.
A 2-column table with 4 rows. Column 1 is labeled Time (hours) with entries 0, 1, 2, 3. Column 2 is labeled Distance (miles) with entries 1, 4, 7, 10.

The points would lie on a straight line that passes through the origin, so the relationship is proportional.
The points would not lie on a straight line, so the relationship is not proportional.
The points would lie on a straight line that does not pass through the origin, so the relationship is not proportional.
The equation y = 4x represents the data.
The equation y = 4x does not represent the data

Given that 3x-y : x+2y = 2 : 5, Determine the ratio x:y
N76 [4]

Answer:

x : y = 9 : 13

Step-by-step explanation:

Given that

3x - y : x + 2y = 2 : 5

Express the ratio in fractional form, that is

\frac{3x-y}{x+2y} = \frac{2}{5} ( cross- multiply )

5(3x - y) = 2(x + 2y) ← distribute parenthesis on both sides )

15x - 5y = 2x + 4y ( subtract 2x from both sides )

13x - 5y = 4y ( add 5y to both sides )

13x = 9y ( divide both sides by 13 )

x = \frac{9}{13} y ( divide both sides by y )

\frac{x}{y} = \frac{9}{13} , that is

x : y = 9 : 13

Find the x-intercepts of the parabola with vertex (1, -9) and y intercept at (0, -6).
Sergio [31]
Hello,

Equation is y=k(x-1)²-9
and when x=0,y=-6==>-6=k*1²-9==>k=3

y=3(x-1)²-9
when y=0, 3(x-1)²-9=0
==>(x-1-√3)(x-1+√3)=0
x-intercepts are (1+√3,0) and (1-√3,0)

Answer B.
