2(x+3) < 5

Let's see how we got this answer:

a. The 2 represents the word "twice" in the question.

b. The x+3 represents the "sum of x and 3"

c. and lastly less than 5 is represented by the less than sign

So that's how we got the answer 2(x+3) < 5

Answer please struggling

Julli [10]

Answer:

x ≈ 28.2

Step-by-step explanation:

Δ CAB ≅ Δ CDE then corresponding sides are in proportion, that is

$\frac{CA}{CD}$ = $\frac{CB}{CE}$ , substitute values

$\frac{14+x}{x}$ = $\frac{18.7+9.3}{18.7}$ = $\frac{28}{18.7}$ ( cross- multiply )

28x = 18.7(14 + x) ← distribute

28x = 261.8 + 18.7x ( subtract 18.7x from both sides )

9.3x = 261.8 ( divide both sides by 9.3 )

x ≈ 28.2 (to the nearest tenth )

If f(x) = 4x + 3 and g(x) = 3x, evaluate for X = -1/2

miskamm [114]

Answer:

$f(-\frac{1}{2}) = 1$

$g(-\frac{1}{2} ) = -\frac{3}{2}$

Step-by-step explanation:

Given the function $f(x) = 4x + 3$ and the function $g(x) = 3x$ , to evaluate for $x=-\frac{1}{2}$ , you need to substitute it into each function.

Then, for the function f(x), when $x=-\frac{1}{2}$ , you get:

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

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

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

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

$f(-\frac{1}{2}) = 1$

For the function g(x), when $x=-\frac{1}{2}$ , you get:

$g(-\frac{1}{2} ) = 3(-\frac{1}{2})$

$g(-\frac{1}{2} ) = -\frac{3}{2}$

What is the equation in point-slope form of the line that passes through the point (-5, 6) and has a slope of 2/3

Aleks [24]

Answer:

<h2> y - 6 = ²/₃(x + 5) </h2>

Step-by-step explanation:

The point-slope form of the equation of a line: y - y₁ = m(x - x₁), where m is the slope and (x₁, y₁) is the point the line passing through.

m = ²/₃

(-5, 6) ⇒ x₁ = -5, y₁ = 6

So the point-slope form of the equation:

y - 6 = ²/₃(x - (-5))

or: y - 6 = ²/₃(x + 5)
