Answer:
Let's define all the possible forms:
slope-intercept: y = a*x + b
point-slope: y - y1 = a*(x - x1) (where (x1, y1) is a point in the line)
standard form: a*x + b*y = c
then:
a) 7x + 5y = 8
This is in standard form.
b) y − 5 = 3*(x − 9)
This is in point slope form.
c) y = 7x + 9
This is in slope-intercept form.
d) 8x − 9y = −2
This is in standard form.
<h3>Question:</h3>
2x-5y=-28 find the value of y when x equals -19
<h3>Answer:</h3>
Y = - 2
<h3>Step-by-step explanation:</h3>
First you plug in -19 where x is 2(-19)-5y = -28
Remove parentheses -2 · 19-5y= -28
Multiply -2 by 19 -38-5y= -28
Add 38 to both sides -5y = 10
Divide both sides by -5 [tex]\frac{-5y}{-5} =\frac{10}{-5}[/tex
you will get -2 which is the answer.
Hope this helped!
Answer:
If y = 30, x = 10
Explanation:
If you extend the line to reach the y-value of 30, the x-value of the point will be 10. So, if y = 30, x = 10.
Good luck ^^
→ A plane contain three non - collinear points.
B) 11x3 - 2x2 + x
Why? because the equation (<span>8x3 – 2x2 + x + 3x3) is equivalent to the equation of (</span><span>11x3– 2x2+ x) which they both equal the sum of (=29 + x)
Hope this helps!
Have a great day.</span>
