Answer:
9
Step-by-step explanation:
A quadratic equation is
The axis of symmetry is 1. This means that some value of
-b/2a =1.
f(0) represent one of the horinzontal roots. Since f(0) equal 0, the constant is 0.
Notice how x=1 is the line of symmetry. This means when x=4 and x=-2, the quadratic is equal. so consider this equation.
=-24
16a+4b= -24
4a-2b=-24
Solve for a by elimination.
2(4a-2b=-24)= 8a-4b=-48
Add both equations.
(16a+4b=-24)+(8a-4b=-48)= 24a=-92
Solve for a.
24a=-92
a=-3
Subsitute to in for b.
16(-3)+4b=-24
-48+4b=-24
4b=24
b=6
This means a=-3
b=6
So b-a is
6+3=9
Well I THINK triangle ABC is just a stretched out version of triangle DEF.
To find the area of a triangle, you multiply base and height, and divide by 2.
Area of DEF is 6, so that means that (4 * x)/2 = 6.
6*2 = 12....
4 * x = 12........
4 * 3 = 12.
x = 3.
Comparing DEF to ABC: ABC's base is 3 times as long as DEF's. So that means the height must be three times as long.
3*3 = 9.
(12 * 9)/2 =54
The arithmetic formula is expressed as an = a1 + d *(n-1)where n is an integer. Substituting from the given a1 = -12 and a27 = 66, 66 = -12 + d *(27-1). hence , d is equal to 3. a42 thus using the formula is equal to 111. The final answer to this problem is 111.
2/3
There are 6 people at the table and 4 of them have names that start with m. So the fraction is 4/6 and that simplified is 2/3
Answer:
2
Step-by-step explanation:
0! + 1!
= !1 / 1 + 1!
= 1 + 1
= 2
