Answer: multiply x by 2 in the first equation and subtract the second equation

Step-by-step explanation:

To solve a system of linear equations by elimination method , our first step is to make its (either x or y) coefficient same.

For that we multiply a number to both sides of the equation not to only one term.

So by checking all the given options it is pretty clear that the last option is not applicable for elimination method because in this 2 is multiplied to only one term, which proceeds to loose the balance of the equation.

Thus , an INCORRECT step that will NOT produce a  system with the same solution is "multiply x by 2 in the first equation and subtract the second equation ".

Which equation represents the graph of y= cosx reflected across the x-axis then shifted vertically down by 2 units?
Phoenix [80]

Answer:

  y = -cos(x) -2

Step-by-step explanation:

Multiplying the function value by -1 reflects it across the x-axis. Adding -2 to the function value shifts it down by two units.

reflected: y = -cos(x)

then shifted: y = -cos(x) -2

Given a triangle with: a =<br> 150, A = 75°, and C = 30°<br> Using the law of sines gives: c = 0
koban [17]

Answer:

c = 77.6

Step-by-step explanation:

You may have entered the measure of a side as the measure of an angle.

\dfrac{\sin A}{a} = \dfrac{\sin C}{c}

\dfrac{\sin 75^\circ}{150} = \dfrac{\sin 30^\circ}{c}

c\sin 75^\circ = 150 \sin 30^\circ

c = \dfrac{150 \sin 30^\circ}{\sin 75^\circ}

c = 77.6

You are correct. Good job!

Identify an equation in slope-intercept form for the line parallel to y = 5x + 2
Elanso [62]

Answer:

D. y = 5x + 29

Step-by-step explanation:

To write an equation of a line in slope-intercept form, we need to find the slope and the y-intercept.

The equation of a line is y=mx + b.

x and y are the coordinates of any point on a line.

m is the slope.

b is the y-intercept.

Lines are parallel to each other when they have the same slope. A line parallel to y = 5x + 2 would also have the slope 5.

m = 5

Since we have a point on the line, (-6, -1) and the slope, 5, there is only one missing variable, b, the y-intercept.

Substitute the known information into the equation and isolate b.

y = mx + b

-1 = 5(-6) + b  <=Simplify by solving 5 X -6

-1 = -30 + b

-1 + 30 = -30 + 30 + b  <= Add 30 to both sides to isolate b

29 = b

b = 29  <= Standard formatting puts the variable on the left side

Put the m and b values into the equation of a line to solve:

y = mx + b

y = 5x + 29
