The equation in slope-intercept form for the line with slope of 8 and passing through (1,8) is y = 8x
<h3>What is slope intercept form ?</h3>
One of the most widely used forms for expressing a line's equation is the slope intercept form of a straight line. If you know the slope of the straight line and the y-intercept, you can use the slope intercept formula to determine the equation of the line ( the y-coordinate of the point where the line intersects the y-axis). Every point along a line must satisfy its equation in order for it to exist.
y=mx + b is the equation in slope intercept form
x=1, y=8
y=8x+ b
8 = 8 + b
b= 0

For the circle we can just do 7.5^2*3.14=176.625 because if you put the 2 semi circle you get a whole circle.
and if the diameter is 15 then the width of the rectangle is 15 so 28*15=420+176.625=596.625
Use the formula or complete the square.
The zeroes of the quadratic can be real and rational; real and irrational; complex conjugates.
If the quadratic is ax²+bx+c, x=(-b+√b²-4ac)/2a.
If b² > 4ac the solutions are real. If b²-4ac is a perfect square, the solutions are real and rational; otherwise they’re real but irrational.
If b² < 4ac the solutions are complex.
Answer:
Option C is correct.
288 degree measure could he have rotated the pentagon so that is mapped onto itself
Step-by-step explanation:
Given: Patrik rotated the pentagon about its center.
A Rotational symmetry of a regular polygon is based on the number of vertices it has.
If the Pentagon figure is rotated about its center, each vertex lands exactly on the top of where it started.
Since you have 5 vertices, so your starting vertex can land in 5 different starting places and still come up with the same figure.
So if you take rotations to each consecutive vertex.
⇒a rotation of 72 degree, 144 degree, 216 degree, 288 degree and 360 degree will result in the same figure.
Therefore, 288 degree measure could he have rotated the pentagon so that is mapped onto itself.
Answer: 42
Step-by-step explanation:
3 times 7 (the number of plants last weekend) =21.
But this is half the quantity of plants he wants to pot next weekend.
So, the double of 21 is 42.
