Answer:
1
Step-by-step explanation:
Since all 5 terms are like terms they can all be combined into 1 term. For example, 3x + 8x + 5x + 4x + 19x = ?. Since they all have the term x they can be combined into 39x. That leaves 1 term.
y = - 4x + - 8 is equation of slope-intercept form.
What is in slope-intercept form?
- Given the slope of the line and the intercept it forms with the y-axis, one of the mathematical forms used to derive the equation of a straight line is called the slope intercept form.
- Y = mx + b, where m is the slope of the straight line and b is the y-intercept, is the slope intercept form.
the equation of slope - intercept form
y = mx + c
( -1 , -4 ) is point shown in graph
slope = -y/x
= - ( -4)/-1 = 4/-1 = -4
- 4 = -4 * - 1 + c
- 4 = 4 + c
c = - 4 - 4 = - 8
put value of c in the equation of slope - intercept form
y = - 4x + - 8

I have a math calculate and got the awnser
Answer:
Step-by-step explanation:
You have to use the discriminant for this. If the quadratic is 
, then
a = -4, b = -3, and c = 7. The formula for finding the discriminant is
which comes from the quadratic formula, but without the square root sign. Filling in:
which simplifies down to
D = 9 + 112 so
D = 121. This is a perfect square, so the solutions will be 2 real. Just so you know, you will NEVER have a solution like the one offered in the third choice down. If you have one imaginary root, you will ALWAYS have a second by the conjugate rule.
