Answer:
x=-69/7
Step-by-step explanation:
f (-1) f (x)=(x-10) 3+4
-1=(x-10) 3+4
-1=(x-10) 7
You will multiply 7 by (x-10)
-1=7x-70
Well move the-1 to the right hand side which will become+1 and move the+7x to the left hand side which will become -7x
-7x=-70+1
-7x=-69
So you will divide both sides by-7
-7x/7=-69/7
x=-69/7

For this case we must solve the following expression:
![-11 (-7)](https://tex.z-dn.net/?f=-11%20%28-7%29)
By law of multiplication of signs we have to:
![- * - =+\\- * + = -\\+ * - = -\\+ * + =+](https://tex.z-dn.net/?f=-%20%2A%20-%20%3D%2B%5C%5C-%20%2A%20%2B%20%3D%20-%5C%5C%2B%20%2A%20-%20%3D%20-%5C%5C%2B%20%2A%20%2B%20%3D%2B)
Also we must find the product of 11 and 7, this is equivalent to:
![11+ 11+ 11+ 11 +11+ 11 + 11 = 77](https://tex.z-dn.net/?f=11%2B%2011%2B%2011%2B%2011%20%2B11%2B%2011%20%2B%2011%20%3D%2077)
Thus, the result of the expression is +77.
Answer:
![-11 (-7) = 77](https://tex.z-dn.net/?f=-11%20%28-7%29%20%3D%2077)
Answer:
62 cubic yards
Step-by-step explanation:
<em>This is conversion from feet to yards.</em>
<u>Step 1: Write the ratio of yards to feet.</u>
Yard : Feet
1 : 3
<u>Step 2: Find out the volume of mould</u>
1 : 3
x : 186
<em>Cross multiply</em>
3x = 186
x = 62 yards
Therefore, 62 cubic yards of concrete is needed in order to fill the mould.
