Idek why brainly deleted my last one but- solve for x 2/3x - 4 1/2 = -8

BaLLatris [955]

Answer:

The answer is x= -5 1/4

Step-by-step explanation:

Let's solve your equation step-by-step.

2/3x−4 1/2=−8

Step 1: Simplify both sides of the equation.

2/3x+−9/2=−8

Step 2: Add 9/2 to both sides.

2/3x+−9/2+9/2=−8+9/2

2/3x=−7/2

Step 3: Multiply both sides by 3/2.

(3/2)*(2/3x)=(3/2)*(−7/2)

x=−21/4

Answer:

x= −5 1/4

What is the domain and range of the quadratic function given by the equation /(x) = 2(x-4)] - 2

Ray Of Light [21]

The domain of the function is the set of all real numbers and the range of the function is the set of all values greater than -2

<h3>How to determine the domain and the range?</h3>

The function is given as:

f(x) = 2(x -4)^2 - 2

A quadratic function can take any real number as its input.

So, the domain of the function is the set of all real numbers

The vertex of the above function is:

Vertex = (4, -2)

And the leading coefficient is:

a = 2

The y value of the vertex is;

y = -2

Because the value of a is positive, then the vertex is a minimum.

This means that the range of the function is the set of all values greater than -2

Find the equation of the line that passes through (1,3) and is perpendicular to y = 1 − 2 x

egoroff_w [7]

Answer:

$y=\displaystyle\frac{1}{2} x+\displaystyle \frac{5}{2}$

Step-by-step explanation:

Hi there!

Linear equations are typically organized in slope-intercept form: $y=mx+b$ where m is the slope and b is the y-intercept.

Perpendicular lines always have slopes that are negative reciprocals (ex. 1/2 and -2, 3/4 and -4/3)

Determine the slope (m):

$y = 1 -2x$

Rearrange into slope-intercept form:

$y = -2x+1$

Now, we can identify clearly that the slope is -2. Because perpendicular lines always have slopes that are negative reciprocals, a perpendicular line would have a slope of $\displaystyle\frac{1}{2}$ . Plug this into $y=mx+b$ :

$y=\displaystyle\frac{1}{2} x+b$

Determine the y-intercept (b):

$y=\displaystyle\frac{1}{2} x+b$

Plug in the given point (1,3) and solve for b:

$3=\displaystyle\frac{1}{2} *1+b\\\\b=\displaystyle \frac{5}{2}$

Therefore, the y-intercept is $\displaystyle \frac{5}{2}$ . Plug this back into $y=\displaystyle\frac{1}{2} x+b$ :

$y=\displaystyle\frac{1}{2} x+\displaystyle \frac{5}{2}$

I hope this helps!

What is the area of the figure? A) 18 yd2 B) 54 yd2 C) 72 yd2 D) 90 yd2

den301095 [7]

Answer:

72 yd²

Step-by-step explanation:

area of this figure = area of 1st rectangle + area of 2nd rectangle

= l×b + L×B

= 6 × 5 + 14 × 3

=30 + 42

= 72 yd²

I'm a little confused

Olegator [25]

she bought 9 shirts and 4 pants.

9 + 4 = 13 total articles of clothing.

Let's create an equation to model the problem.

x = price of one shirt or one pants

13x + $6 = $71

Subtract $6 from both sides.

13x = $65

Divide both sides by 13

x = $5

Each shirt or pair of pants costs $5.

The correct answer is D.
