Xints are where y=0
0=x^2+4x-12
0=(x-2)(x+6)
x-2=0
x=2
x+6=0
x=-6
(x,y)
xints are
(2,0) and (-6,0)
Answer:
- c = 9
Step-by-step explanation:
given c = - 9 ← multiply both sides by - 1
c × - 1 = - 9 × - 1 ⇒ - c = 9
Answer:
27%
Step-by-step explanation:
In the row Students ages 14-17 and column skip breakfast, there are 24 students.
In row total and column total, there 90 students.
24/90 are students age 14-17 who skip breakfast
24/90 = 12/45 = 0.26666667
Percent = decimal x 100
Percent = 0.26666667 x 100 = 26.666667
26.666667 is rounded to 27%
Hope this helps :)
Have a nice day!
Im not rlly that good at math but I believe in u smart ppl
Slope intercept form: y = mx + b
m = slope
b = y-intercept
The line passes through the y-axis at the point (0, -5). So, -5 is the y-intercept.
We can use the points (0, -5) and (5, 0) to solve.
Slope formula: y2-y2/x2-x1
0-(-5)/5-0)
5/5
1
The slope is 1.
Substitute these values into the equation.
y = 1x + (-5)
y = x - 5
Therefore, the answer is [ y = x - 5 ]
Best of Luck!
