Answer:

\dfrac{-8}{x+3}

Step-by-step explanation:

We need to find an algebraic expression for the given statement i.e. "the quotient of negative eight and the sum of a number and three".

Let the number be x. Quotient means to divide. It means we need to divide -8 and the sum of x and 3.

So, we can write it as follows :

\dfrac{-8}{x+3}

Hence, this is the required solution.

A circle has its center at the origin, and (5, -12) is a point on the circle. How long is the radius of the circle?
kolezko [41]
(x-center)^2+(y-center)^2=r^2
x^2+y^2=r^2
(5)^2+(-12)^2=r^2
25+144=r^2
169=r^2
r=13

Answer:

a) x=

10°

50°

130°

10°

50°

130°

170°

250°

290°

b) x=

90°

210°

330°

Step-by-step explanation:

2 sin (3x) = 1

a)  look at the graph, y=1 when x is near:

10°,  50°, 130°, etc

in the equation: 2 sin (3x) = 1  ⇒ sin (3x) = 0.5  ⇒ 3x = 30° (and others)  ⇒ x = 10° (and others).  So the values given in solution (10°,  50°, 130°, etc) are true

b) is evident

I need help with this two questions.
mezya [45]
Always get rid of denominators first. Multiply both right and left side by 6
-7 (6) = -c (6)/6 + 12(6)
-42 = -c + 72
c = 72 +42
c = 114

rearrange like terms together
42 = 18 - 4x
4x = 18 -42
4x = -24
divide both sides by 4
x = -6

14y+36=106 solve the problem
3241004551 [841]

Answer:

y = 5

Step-by-step explanation:

14y + 36 = 106. subtract 36 from both sides, so now the equation is 14y = 70 because 36 is cancelled out. now divide both 14y and 70 by 14, which leaves you with y = 5
