Two angles are supplementary. The measure of one angle is 4 times the measure of the other angle. What is the measure of the sma

Alexus [3.1K]

ANSWER

The smaller angle is

$y = 36 \degree$

.EXPLANATION

Let the angles be
$x \: and \: \: y$

where y is the smaller angle.
Since they are supplementary, they will add up to 180°.

This implies that,

$x + y = 180 \degree...(1)$

If one angle is 4 times the other, we can then write the following equation,

$x = 4y...(2)$

We put equation (2) into equation (1) to get,

$4y + y = 180 \degree$

$5y = 180 \degree$

We divide through by 5 to obtain,

$y = 36 \degree$

This implies that,

$x = 4(36)$

$x = 144 \degree$

HELP PLEASE SOMEONE

Rom4ik [11]

$f(x)= \frac{x}{2} -2$ and $g(x)=2 x^{2} +x-3$
(f+g)(x) = $\frac{x}{2} -2+2 x^{2} +x-3$
combining like terms gives you answer choice B

Help me please. I am having troubles with my math homework.

jeyben [28]

Answer: (3) f(8) = g(8)

Step-by-step explanation:

Let's compare the values of f(x) and g(x) when x = 0, 2, 8, and 4

f(x) g(x) Comparison

f(x) = 2x - 3 $g(x)=\dfrac{3}{2}x+1$

f(0) = 2(0) - 3 $g(0)=\dfrac{3}{2}(0)+1$

= -3 = 1 f(0) < g(0)

f(2) = 2(2) - 3 $g(2)=\dfrac{3}{2}(2)+1$

= 1 = 4 f(2) < g(2)

f(8) = 2(8) - 3 $g(8)=\dfrac{3}{2}(8)+1$

= 13 = 13 f(8) = g(8)

f(4) = 2(4) - 3 $g(4)=\dfrac{3}{2}(4)+1$

= 5 = 7 f(4) < g(4)

The only statement provided that is true is f(8) = g(8)

H(1)=-6 h(2)= 20 h(n)= h(n-2)+h(n-1) What is the value of h(3)?

Elina [12.6K]

9514 1404 393

Answer:

Step-by-step explanation:

Use the formula with n=3.

h(3) = h(3-2) +h(3-1)

h(3) = h(1) +h(2)

h(3) = -6 +20 . . . . . substitute the given values

h(3) = 14

Solve for x. a²x+(a-8)=(a+8)x

Sergio [31]

$a^2x+(a-8)=(a+8)x\\\\(a+8)x=a^2x+(a-8)\ \ \ \ |subtract\ a^2x\ from\ both\ sides\\\\(a+8)x-a^2x=a-8\\\\(a+8-a^2)x=a-8\ \ \ \ |divide\ both\ sides\ by\ (a+8-a^2)\\\\\huge\boxed{x=\frac{a-8}{a+8-a^2}}\to\huge\boxed{x=\frac{8-x}{a^2-a-8}}$
