Answer: The answer is (B) 2x + 3(3x – 5) = 51
.
Step-by-step explanation: We are given three options and we are to select which choice shows the result of substituting 3x – 5 into the second equation for y.
So, y = 3x - 5.
Since the standard form of a linear equation i two variables is ax + by = c, so the second equation as given in the options must be of the form 2x + 3y = 51.
If we substitute y = 3x - 5, then this equation becomes
2x + 3(3x - 5) = 51.
Thus, (B) 2x + 3(3x – 5) = 51 is the correct option.
Answer:
x = 3
Step-by-step explanation:
To find the value of x. We have to use Exterior Angle Theorem.
It is says "The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles of the triangle."
In the given figure,
45x = 25x + (57 + x)
Now let's find the value of x.
First we need to isolate the variable terms
45x - 25x = 57 + x
20x - x = 57
19x = 57
x = 57/19
x = 3
The value of x = 3.
Thank you.
Answer:
1 unit to the right
Step-by-step explanation:
The y-axis is the vertical line and the point (1,-3) is one unit to the right of the vertical line
Slope: (y2-y1)/(x2-x1)
(1-3)/(1-4) = -2/-3 = 2/3
The slope is 2/3
Answer:
The answer is
<h2>y + 20 = 10( x - 0)</h2>
Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
From the m is 10
Equation of the line using point ( 0 , - 20) is
<h3>y + 20 = 10( x - 0)</h3>
Hope this helps you
