Answer:
a = -1.58
Step-by-step explanation:
1/3 +a+5/4 =0
1/3+5/4= -a
4+15/12 = -a
19/12 = -a
1.58= -a
1.58/-1 = -a/-1
-1.58 = a
Answer:
x² + 2x - 5
Step-by-step explanation:
(f + g)(x) = f(x) + g(x)
f(x) + g(x)
= 2x + 3 + x² - 8 ← collect like terms
= x² + 2x - 5
Slope formula:
(y2-y1)/(x2-x1)
Substitute in the points into the slope formula.
Slope= [10-(-2)] / [(-7)-8]
Slope= (10+2) / (-15)
Slope= 12/-15
Slope= -12/15
Simplify (3 goes into each)
Slope= -4/5
Hope this helps!! :)
Using a theorem (yes i forgot the name of the theorem), we know that because the angles opposite of the sides are congruent, the sides must be congruent aswell. Therefore:
3x - 24 = x + 10
Now solve, starting by using the addition and subtraction properties of equality:
3x - 24 + 24 = x + 10 + 24
3x = x + 34
3x - x = x - x + 34
2x = 34
Now, use the division property of equality:
(2x)/2 = (34)/2
x = 17
Therefore, x = 17.

Yeah definitely the first guy
