The answer for the first one would be 5=10 which would be no solution because 5 does not equal 10. The second answer would be 4.6 but if you can't use decimals then the answer would be -23/5 but that might be the wrong answer but that is what i got

For the first one, we will have to factor out the numbers. So 2 times 4x is 8x and 2 times 5 is 10. Our new expression will now be 8x + 10 = 8x + 10. Now, since these are equal, x must equal 1.

Heyyy ummm... help??

atroni [7]

The statements true for the given function are:

$f(0) = \frac{3}{2}$
$f(4) = \frac{7}{2}$

I tried them all and these two were correct, their solutions are as follows:

= f(x) = 1/2x + 3/2

= f(0) = 1/2 × 0 + 3/2

= f(0) = 0 + 3/2

= f(0) = 3/2

= f(x) = 1/2x + 3/2

= f(4) = 1/2 × 4 + 3/2

= f(4) = 2 + 3/2

= f(4) = 4+3/2

= f(4) = 7/2

So, that's how these two are correct.

kogti [31]

Answer:

$1800

Step-by-step explanation:

Volume of the foundation: 30*12*6 = 2160 cubic feet

we need to convert this into yards because a truckload is 8 cubic yards, 2160/3 = 720 cubic yd

One truckload is 8 cubic yards

# of truckloads needed: 720/8 = 90 truckloads

Cost: $20*90 = $1800

What is perpendicular to y=-1/2x+11

ratelena [41]

You have to find the reciprocal of the gradient - 1/2
And to do that just flip the sign and fraction:
-1/2
1/2
2/1

So the answer is,
Y = 2x + 11
