Answer:
What is missing is -5x - 20
Step-by-step explanation:
To find this, simply solve for the parenthesis as if it were a variable of its own. This will allow you to see exactly what is missing.
8x - (x - 20) = 2x - (_______)
8x - x + 20 = 2x - (_______)
7x + 20 = 2x - (_______)
5x + 20 = - (_______)
-5x - 20 = (_______)
So the answer for the parenthesis is -5x - 20
F(x)=1-x² and g(x)=√(11-4x)
(g+f)(2)=>
1-(2)²+√(11-4(2))
=√3-3
(f/g)(-1)
(1-(-1)²)/(√(11-4(-1))
=0
(g-f)(-1)
√(11-4*-1)-(1-(-1)²
=√15
(g×f)(2)
1-(2)²×√(11-4(2))
-3√3
Answer:
22
Step-by-step explanation:
Boys to Girls
5 to 6
10 to ?
Since 10 is twice as much as 5, we have to multiply the number of girls by 2. 6 times 2 is equal to 12. Then, since we need to find the total number of boys and girls, we have to add both sides. 10 (boys) plus 12 (girls) equals 22.
Answer:
0.278
Step-by-step explanation:
5 + 4 = 9
*
= 0.2777...
Try to do the others on your own using the information I gave you.
If 2 lines (or line segments) are perpendicular, then the product of their slopes is equal to -1.
Thus, since the given line segments are perpendicular, we have:

.
Multiplying both sides of the equation by 15, we get d=-15.
Answer: d=-15
