There is no single solution but there is a group of solutions also known as the interval.

$-x+4>2 \\-x>-2 \\x$

This can be written with an interval.

$x\in(-\infty, 2)$

Hope this helps.

On a scale model of a building, 14 inch represents 38 foot. What length on the model represents 1 foot?

enot [183]

We are given that 14 inch represent 38 foot.
To know the model length that represents 1 foot, all we have to do is cross multiplication as follows:
14 inch ..............> 38 foot
?? inch .............> 1 foot
length on model = (1*14) / 38
length on model = 7/19 inch = 0.36842 inch

Which of the following coordinates exists on the line y = 3x + 1?

Natalija [7]

We are given

equation of line as

$y=3x+1$

we will check each options

option-A:

we can plug (3,1)

x=3 and y=1

$1=3*3+1$

$1=10$

we can see that

they are not equal

so, this is FALSE

option-B:

we can plug (-1,-2)

x=-1 and y=-2

$-2=3*-1+1$

$-2=-2$

we can see that

they are equal

so, this is TRUE

option-C:

we can plug (-3,4)

x=-3 and y=4

$4=3*-3+1$

$4=-8$

we can see that

they are not equal

so, this is FALSE

option-D:

we can plug (2,6)

x=2 and y=6

$6=3*2+1$

$6=7$

we can see that

they are not equal

so, this is FALSE

Answer:

The radius is 5 cm

Step-by-step explanation:

The formula for the area of a circle is : $\p*radius^2$

To work out the length of the radius you would first need to divide the area of 78.5 cm by pi (pi=3.14), this gives you $25cm^2\\$ . This is because by dividing the area by pi we are isolating the value of the radius squared.

The final step is to work out the radius. You can do this by finding the square root of the radius squared which is 25, this gives you 5 cm. This means that the radius is 5 cm. This is because the square root is a number that when squared equals that number.

1) Divide 78.5 by pi.

$78.5/\pi=25cm^2$

2) Find the square root of 25 cm squared.

$\sqrt{25} =5 cm$

In this question pi is 3.14
