Answer:

x=67, y=67

Step-by-step explanation:

All sides in triangle equal 180. First we subtract to find the rest of triangle: 180-46=134. 134 is the total of x and y. Because we have 2 amounts we need to find we can divide: 134/2. This results in 67.

We know this is true because the sides are equal as well, hinting that x and y are both equal to each other. Also, 67+67+46=180 confirming the answer.

Consider functions fand g.<br> f(x) = -13<br> g(x) = |1/8x-1|

stira [4]

Answer:

We conclude that

(g o f) (4) = 9

Hence, option C is correct.

Step-by-step explanation:

Given

f(x) = -x³

g(x) = |1/8x - 1|

To determine

(g o f) (4) = ?

Using the formula

(g o f) (4) = g[(f(4)]

first we need to determine f(4)

so substituting x = 4 into f(x) = -x³

f(x) = -x³

f(4) = -(4)³ = -64

(g o f) (4) = g[(f(4)] = g(-64)

so substitute x = -64 in g(x) = |1/8x - 1|

$g\left(x\right)=\left|\frac{1}{8}x-1\right|$

substitute x = -64

$g\left(-64\right)=\left|\frac{1}{8}\left(-64\right)-1\right|$

$=\left|-\frac{1}{8}\cdot \:64-1\right|$

$=\left|-8-1\right|$

$=\left|-9\right|$

Apply absolute rule: |-a| = a

$=9$

Therefore, we conclude that

(g o f) (4) = 9

Hence, option C is correct.

Use the discriminant to determine the number of real solutions to x^2+7x-7=0

valkas [14]

Step-by-step explanation:

In general, you can skip the multiplication sign, so 5x is equivalent to 5⋅x.

In general, you can skip parentheses, but be very careful: e^3x is e3x, and e^(3x) is e3x.

Also, be careful when you write fractions: 1/x^2 ln(x) is 1x2ln(x), and 1/(x^2 ln(x)) is 1x2ln(x).

If you skip parentheses or a multiplication sign, type at least a whitespace, i.e. write sin x (or even better sin(x)) instead of sinx.

Sometimes I see expressions like tan^2xsec^3x: this will be parsed as tan2⋅3(xsec(x)). To get tan2(x)sec3(x), use parentheses: tan^2(x)sec^3(x).

Similarly, tanxsec^3x will be parsed as tan(xsec3(x)). To get tan(x)sec3(x), use parentheses: tan(x)sec^3(x).

From the table below, you can notice that sech is not supported, but you can still enter it using the identity sech(x)=1cosh(x).

If you get an error, double-check your expression, add parentheses and multiplication signs where needed, and consult the table below.

All suggestions and improvements are welcome. Please leave them in comments.

Answer:

P) = 1/2 jawbreaker

simplified P) 3/6 = 1/2 jawbreaker

Which both mean the same, so show simplified if asked and either answer if not asked would be marked high.

as 2/6 + 1/3 = 3/6

1 - 3/6 = 3/6

= 1/2 are the workings.

Step-by-step explanation:

Jelly bean = 1/3 = 2/6

Gumdrop = 1/6

2/6 + 1/6 = 3/6 = the difference of 1

1-3/6 = 3/6

Therefore; P) = 3/6 jawbreaker
