Answer:

x=0

Step-by-step explanation:

2(3x-1)=6x-2

6x-2=6x-2

then plus two on both sides

6x=6x

WILL MARK BRAINLIEST! PLEASE HELP!
vodomira [7]

The formula y = mx + b sometimes appears with


different symbols.


For example, instead of x, we could use the


letter C. Instead of y, we could use the letter F.


Then the equation becomes


F = mC + b.


All temperature scales are related by linear


equations. For example, the temperature in


degrees Fahrenheit is a linear function of degrees Celsius.

Water freezes at: 0°C, 32°F


Water Boils at: 100°C, 212°F


Hope this helps!

Write the equation of a line that is parallel to 3x+2y=10 and passes through the point (4,-5). Answer in slope-intercept form.
SCORPION-xisa [38]

The equation of line is:

y = \frac{-3}{2}x+1

Further explanation:

The standard form of equation in point-slope form is:

y = mx+b

Given equation is:

3x+2y=10

We have to convert it into point slope form, for which we have to isolate y on one side of equation

3x+2y = 10\\2y = -3x +10\\y = \frac{-3}{2}x + \frac{10}{2}\\y = \frac{-3}{2}x + 5

Comparing with standard form:

m = -3/2

As the new line is parallel to given line, their slopes will be equal

So,

y = \frac{-3}{2}x+b

To find the value of b, putting the given point (4,-5) in equation

-5 = \frac{-3}{2}(4)+b\\-5 = -6+b\\b = -5+6 \\b = 1\\So\ the\ equation\ is:\\y = \frac{-3}{2}x+1

Keywords: Point-slope form, equation of line

What is the range if the function in this table?
Lana71 [14]

The range of a function is the set of y-values the function contains. Thus, in this case, the range would be the set of values under the y column, as this represents the y-values the function produces.


We see "2, 3, 4, 2" under the y column. Since we are establishing a set of values, we are going include all the values under the column, which includes 2, 3, and 4. We are <em>not </em>going to repeat the second 2 because it isn't necessary, as 2 is already in the set thus.


Thus, the final set for the range of the function is {2, 3, 4}, or Choice A.
