Answer:

The number is -1/2

Step-by-step explanation:

Let x be the number

2x+8 = 7

Subtract 8 from each side

2x+8-8 = 7-8

2x = -1

Divide each side by 2

2x/2 =-1/2

x = -1/2

The number is -1/2

Answer:

2x + 8 = 7

x = -1/2

Step-by-step explanation:

"a number" can be signified by a variable.

So 2 times a number would give you 2x

And 8 would mean to add 8.

Is 7 means the end result is 7.

So 2x + 8 = 7

x = -1/2

8. Solve the following triangle for all missing sides and angles.

vova2212 [387]

Answer:

Parte1 :

∡B= 180 - (42 + 83)= 55°

Parte2 :

Using the law of sines : $\frac{sin 42}{a} = \frac{sin 55}{175}$ ⇔ $a = sin42 \frac{175}{sin 55}$ ⇔ a= 142.95

Parte3 :

Using the same law : $c = sin 83\frac{a}{sin 42}$ or $c= sin 83\frac{175}{sin 55}$ ⇔ c= 212.04

Given limit of f (x) = 4 as x approaches 0. what is limit of one-fourth left-bracket f (x) right-bracket superscript 4 baseline

The limit of the given function if $\lim_{x \to 0} f(x)=4$ is 64

<h3>Limit of a function</h3>

Given the following limit of a function expressed as;

$\lim_{x \to 0} f(x)=4$

We are to determine the value of the function

$\frac{1}{4} \lim_{x \to 0} [f(x)]^4$

This can also be expressed as

$\frac{1}{4} \lim_{x \to 0} [f(x)]^4\\ = \frac{1}{4}(4)^4 \\=1/4\times 256\\=64$

Hence the limit of the given function if $\lim_{x \to 0} f(x)=4$ is 64
