EXPLANATION
The table contains these two points (-4,-3) and (2,-4.5)
The slope of this line is given by;
The y-intercept can be obtained by finding the equation of the line in the form:
We plug in the slope and the point (-4,-3) to find c.
This implies that,
Hence the y-intercept is -4.
The given line is
This is already in the slope intercept form:
The slope is
The y-intercept is c=1
Answer:
<u>9x² + 42x + 49</u>
Step-by-step explanation:
<u>Identity</u>
In this case, x = 3x and a = 7, so <u>substitute</u> the values.
- (3x + 7)²
- (3x)² + 2(3x)(7) + (7)²
- <u>9x² + 42x + 49</u>
Answer:
not straight 2,4
Step-by-step explanation:
Answer:
29 degrees
Step-by-step explanation:
angle ABD = (x + 9) degrees
angle DBC = (2x - 19) degrees
angle ABC = angle ABD + angle DBC
50 = (x + 9) + (2x - 19)
= 3x - 10
3x = 50 + 10
x = 60/3
x = 20
Substitute x = 20 into angle ABD = (x + 9)
angle ABD = 20 + 9
angle ABD = 29 degrees
Use the formula (b/2)^2 in order to create a new term. Solve for x by using this term to complete the square.
x = 1 ±
