Answer:

x = -12

Step-by-step explanation:

4/3x + 12 = - 4   (multiply 3 both side)

4x + 36 = - 12 (minus 36 both side)

4x + 0 = -12

4x = -12 - 36

4x = - 48 (divide both side)

4x ÷ 4 = x

-48 ÷ 4 = -12

Answer: x = -12

<u>Answer:</u>

\frac{200}{3} square units

<u>Step-by-step explanation:</u>

Knowing the function and that the triangle is formed by both the x and y-axis, you already have the triangle's height, which is 10 (the y-intercept of the functon) To find the base length, all you have to do is find the x-intercept. To do that, simply:

Set function equal to 0 and solve for x:

f(x) = 10 - \frac{3}{4} x

0 = 10 - \frac{3}{4} x

\frac{3}{4} x = 10

x = \frac{40}{3}

This means that the base length of the triangle is also  \frac{40}{3}. Now that you have the height and base length, you can

Plug values into the formula for the area of a triangle:

The area of a triangle is \frac{1}{2} × height × base

Height = 10, base = \frac{40}{3}

Area = \frac{1}{2} × 10 × \frac{40}{3}

Area = 5 × \frac{40}{3}

Area =  \frac{200}{3}

Need help with the problem in the photo.
mr_godi [17]

Answer:

  B.  3x -2y = 10

Step-by-step explanation:

The given line rises three units for each two units of run to the right. Hence its slope is 3/2. A parallel line will also have a slope of 3/2.

Of the equations we can see, selection B has a slope of 3/2. It can be rewritten in slope-intercept form as ...

  3x -10 = 2y . . . . . add 2y-10 to isolate the y-term; next divide by 2.

  y = 3/2x -5 . . . . . the coefficient of x is the slope

What is the solution set of x2 + 5x- 5 = 0? oss-355 S +385 o sus S* o {stay -S-345 , 30 O S=5+375 5+3/5 2 0 --375 -5 +385 2
jolli1 [7]

Given the quadratic equation:

x^2+5x-5=0

Using the general solution for quadratic equations:

ax^2+bx+c=0\Rightarrow x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}

From the problem, we identify:

\begin{gathered} a=1 \\ b=5 \\ c=-5 \end{gathered}

Then:

x=\frac{-5\pm\sqrt{25+20}}{2}=\frac{-5\pm3\sqrt{5}}{2}

And the solution set is:

\lbrack\frac{-5-3\sqrt{5}}{2},\frac{-5+3\sqrt{5}}{2}]
