PLEASE HELP ASAP!!!!


Which graph shows a proportional relationship between x and y?

Answer:

A. y = 2x - 3

Explaination:

It can't be negative because then the slope would be going downward from left to right, this line is going upwards. Also, the steepness of the slope proves it is a slope of 2 because a slope of 1/2 isn't very steep. You can also count 1 unit over and look how much the line changes to find the slope.

Answer:

A

Step-by-step explanation:

X intercept : (3/2 , 0)

Y intercept : (0 , -3)

Slope: m=2

Ans

B,D,F

Step-by-step explanation:

Y=5-x^2

Y=3x^2+1

Y=x^3

Answer:

16 weeks

Step-by-step explanation:

Set up a proportion with the equation.

a = 2w

8

2 x 8= 16 then 16/1=16

so she was at school for 16 weeks.

Answer:

The answer is A

Step-by-step explanation:

The line is perpendicular to RS through S

There are several constructions that can be done with the straightedge and the compass.

The statement that describes the figure Kelly is constructing is: (c) a line parallel to RS through Q

From the figure, we have the following observations

When a line is drawn from point Q through the intersection of these lines, the line would be parallel to line RS.

Hence. we can conclude that:

Kelly is constructing (c) a line parallel to RS through Q

Answer:

4/15.

Step-by-step explanation:

1/3(1/5) + 1/5

1/15 + 1/5

1/15 + 3/15

4/15

Answer:

4/15

Step-by-step explanation:

[tex]( \frac{1}{3} \times \frac{1}{5} ) + \frac{1}{5} \\ \frac{1}{15} + \frac{1}{5} \\ \frac{1}{5} + \frac{3}{13} \\ \frac{1 + 3}{15} = \frac{4}{15} [/tex]

The hurdle and runner form a right triangle (see attached picture) such that

sin(30°) = h / (5 ft)

and

cos(30°) = x / (5 ft)

where h is the height of the hurdle and x is the horizontal distance from where the runner jumps to the hurdle. So

h = (5 ft) sin(30°) = 5/2 ft = 2.5 ft

x = (5 ft) cos(30°) = (5√3)/2 ft ≈ 4.33 ft

Answer:

A

Step-by-step explanation:

Answer:

One solution:(-8,-3)

Step-by-step explanation:

 x = 5y + 7

Plug this in for variable  x  in equation [2]

  [2]    -3•(5y+7) + 14y = -18

  [2]     - y = 3

Solve equation [2] for the variable  y  

  [2]    y = - 3  

By now we know this much :

   x = 5y+7

   y = -3

Use the  y  value to solve for  x  

   x = 5(-3)+7 = -8  

Solution :

{x,y} = {-8,-3}

Step-by-step explanation:

A relative maximum (or minimum) point is a point that is higher (or lower) than all of the points surrounding it.

This graph has a relative minimum point where A(t)=-12A(t)=−12A, left parenthesis, t, right parenthesis, equals, minus, 12, which means that Keith's lowest altitude was \textit{12}12start text, 12, end text meters below the ground.

A positive (or negative) interval is a domain interval over which the function values are all positive (or negative).

Since A(t)>0A(t)>0A, left parenthesis, t, right parenthesis, is greater than, 0 over the interval [6.5,10][6.5,10]open bracket, 6, point, 5, comma, 10, close bracket, this is a positive interval. This means that between the \textit{6.5}6.5start text, 6, point, 5, end text- and \textit{10}10start text, 10, end text-minute marks, Keith was above the ground.

An increasing (or decreasing) interval is a domain interval over which the function values increase (or decrease) as the input variable increases.

In this graph, the interval, 5, point, 5, comma, 8, close bracket is an increasing interval. This means that between the   end text-minute marks, the elevator was going up.

Step-by-step explanation:

5% of x is =8

5/100 * X= 8

x=8*100/5=800/5=160

12% of x =5

x=41.666 approximately

8% of x=12

x=12*100/8=1200/8=150

5% of x= 12

x=12*100/5=1200/5=240

Step-by-step explanation:

Given:

Of the 100 people polled, 20 like playing golf.

To find:

The percentage of the people who like playing golf.

Solution:

In the poll,

Total number people = 100

Who like playing golf = 20

Now, percentage of the people who like playing golf is

[tex]Required \%=\dfrac{\text{Number of people who like playing golf}}{\text{Total number people in poll}}\times 100[/tex]

[tex]Required \%=\dfrac{20}{100}\times 100[/tex]

[tex]Required \%=20[/tex]

Therefore, 20% of the people like playing golf.

Answer:

A and C

Step-by-step explanation:

B has a domain connected to many other ranges which makes a relationship but confuses the whole function making it incorrect.

For answer D, the x coordinates 1 and 3 both have two y coordinates. That again makes a relationship but confuses the function making that answer incorrect.

In answer A, no domain is repeated in any of the points making it a function.

In answer C, again no domains are paired with more than one range making it a function. That why A and C are the answers
