Math really can seem hopeless at times, can it? I can't recall the number of times that I've given up on math, but enough about me! There is a certain theorem in Geometry that states that the angle formed by two secant segments, 9x-5, is equal to half the difference between the intercepted arcs (64 and 158). I know this might sound extraterrestrial, but bear with me! Here is what it would look like in numerical form.

angle formed by secant segments = (1/2) (big intercepted arc - small intercepted arc)
(9x - 5) = (1/2)(158 - 64)
9x - 5 = (1/2)(94)
9x - 5 = 47
9x = 52
x = 52/9 or 5 7/9

Solve the equation for all real solutions.<br> 15r2 – 6r – 3 = -2r

Solnce55 [7]

Answer:

Step-by-step explanation:

hello :

15r² – 6r – 3 = -2r

15r² – 6r – 3 +2r =0

15r²-4r -3 =0

delta =b² -4ac a=15 b=-4 c=-3

delta =(-4)² - 4(15)(-3)=196 = 14²

r1 = (-b - √delta ) /2a = (4-14)/30 = -10/30 = -2/6 = -1/3

r2 = (-b + √delta ) /2a = (4+14)/30 = 18/30 = 3/5

For what values of m does the graph of y = 3x2 + 7x + m have two x-intercepts?

frutty [35]

Answer:

m < $\frac{49}{12}$

Step-by-step explanation:

Using the discriminant Δ = b² - 4ac

Given a quadratic equation in standard form, y = ax² + bx + c

Then the value of the discriminant determines the nature of the roots

• For 2 real roots then b² - 4ac > 0

Given

y = 3x² + 7x + m ← in standard form

with a = 3, b = 7 and c = m, then

7² - (4 × 3 × m) > 0

49 - 12m > 0 ( subtract 49 from both sides )

- 12m > - 49

Divide both sides by - 12, reversing the symbol as a result of dividing by a negative quantity.

m < $\frac{49}{12}$

Try to simplify 72/6+85/6

Reil [10]

72/6+ 85/6
= (72+ 85)/6
= 157/6
= (156+1)/ 6
= 156/6+ 1/6
= 26+ 1/6
= 26 1/6

The final answer is 26 1/6~
