By order of operations, you would want to do the multiplication first:

(12/3) * (4/5) = 4 * 4/5 = 16/5

Then:

16/5 + 4/5 = 20/5 = 4

The answer is 4.

12/3(4/5)+4/5

\frac{12}{3} *\frac{4}{5} +\frac{4}{5}

Using PEMDAS rule,

multiplying first

\frac{12}{3} *\frac{16}{5} +\frac{4}{5}

Adding the two fractions we get:

20/5

=4

Y=3/8x−4 write in standard form
Naddik [55]
Answer:

y=3/8x-4
Move the expression to the left
y-3/8x=-4
Multiply both sides by 8
8y-3x=-32
Reorder the terms
-3x+8y=-32
Change the signs and standard form is...
3x-8y=32

Coordinate Planes

  • Coordinates (x, y)
  • Slope Formula: \displaystyle m = \frac{y_2 - y_1}{x_2 - x_1}

Step-by-step explanation:

*Note:

Rate of change is slope.

<u />

<u>Step 1: Define</u>

<em>Identify.</em>

Point (-1, -1)

Point (1, -1)

<u>Step 2: Find slope </u><em><u>m</u></em>

Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>.

  1. Substitute in points [Slope Formula]:                                                              \displaystyle m = \frac{-1 + 1}{1 + 1}
  2. [Order of Operations] Simplify:                                                                        \displaystyle m = \frac{0}{2}
  3. Simplify:                                                                                                             \displaystyle m = 0

For what value of k will these pairs of simultaneous equations have no solution?
yKpoI14uk [10]
Kx-3y=k
y=4x+1 ( we will put it in 1st equation )
kx - 3 (4x+1)=k
kx - 12 x - 3 =k
kx - 12 x = k+3
x(k-12) = k+3
x=\frac{k+3}{k-12}
Also y=\frac{5k}{k-12}
We can not divide with zero.
k-12=0
k=12
For k= 12 equations have no solutions.
