HELPPP!!! 10 PTS! M angle (6x + 15) = _____

Mathematics
1 answer:
Llana [10]3 years ago
8 0

Answer:

The value of  ∠(6x + 15) = 57°

Step-by-step explanation:

Here, ∠1 = (9x + 16)°

∠2 = (6x + 15)°  and  ∠3 = 136°

THE SUM OF EXTERIOR ANGLE IS THE SUM OF INTERIOR OPPOSITE ANGLES.

⇒ ∠1 +   ∠2 =  ∠3

or,   (9x + 16)° +  (6x + 15)°  = 136°

or, (9x+ 6x) + (16 + 15)  =  136°

or, 15x = 136° - 31 = 105°

⇒ x = 105° / 15 = 7

or,  The value of x  = 7

So, ∠2 = (6x + 15)°  = 6 (7)  + 15   =  57°

Hence the value of  ∠(6x + 15) = 57°

How much principle, to the nearest dollar, should you invest at 4 percent in order to have $3000 for a vacation to Europe in 3 y
KiRa [710]

Answer:

Principle should be $2,667

Step-by-step explanation:

We need $3000 for a vacation to Europe in 3 years.

Using amount formula,

A=P(1+r)^t

Where, P is principle (P=?)

A is amount (A=3000)

r is rate of interest (r=0.04)

t is time (t=3)

Substitute the values into formula and solve for P

3000=P(1+0.04)^3

3000=P(1.04)^3

P=\frac{3000}{1.04^3}

P=2666.98

P\approx \$2667

Hence, Principle should be $2,667

Factor 6x4 – 5x2 + 12x2 – 10 by grouping. What is the resulting expression?
Vadim26 [7]

Answer:

(6x² - 5)(x² + 2)

Step-by-step explanation:

Given

6x^{4} - 5x² + 12x² - 10 ( factor the first/second and third/fourth terms )

= x²(6x² - 5) + 2(6x² - 5) ← factor out (6x² - 5) from each term

= (6x² - 5)(x² + 2)

The graph of the inequality will be B. on a coordinate plane, a dashed straight line has a positive slope and goes through (0, negative 4) and (3, negative 2). Everything to the right of the line is shaded.

<h3>How to get the graph?</h3>

It can be deduced that the coordinates satisfy the equation of the line.

3y = 2x - 12

Divide through by 3.

y = 2/3x - 4.

The slope is 2/3.

In conclusion, the correct option is B.
