Answer:
The y-intercept is (0, 5).
Step-by-step explanation:
We find the equation of the line in slope-intercept form:
y - y1 = m(x - x1)
y - 13 = 2(x - 4)
y = 2x - 8 + 13
y = 2x + 5 - This is slope-intercept form where the graph passes through the y-axis at y = 5.
Answer:
Your answer is C, 10.7cm
Step-by-step explanation:
The two flat sides of the figure are 3 cm, so that part of the perimeter = 6cm
3cm is the radius of what would be a whole circle. We'll calculate the circumference, then divide by 4.
Circumference = (2)(pi)(r)
C = (2)(3.14)(3)
C = 18.84
18.84/4 = 4.71
Add 4.71 to the 6 cm above, = 10.71
Let me know if you have questions about this.
The correct answer is choice C. Here is the reason. If you substitute the information into the formula this is what it would be:
A = bh/2
13 = x (6x + 1)/2
13 = (6x^2 + x)/2
26 = 6x^2 + x
0 = 6x^2 + x - 26
