Answer:
x=8
base side of isosceles triangle
y=√{8²+8²}=8√2
Answer:
I am going to assume you mean the relationship between x and y.
If the y-intercept is 0, that means the point is on the origin.
So x and y are equal to each other. they are both zero
Answer:
y=2x+7
Step-by-step explanation:
When an equation is parallel to another, it shares the same slope.
Our original line is y=2x-8, and it is in slope-intercept form (y=mx+b)
This means that our slope is 2 because m represents the slope.
The slope of our parallel line will then also be 2.
<u>We can begin to plug that into point-slope form which is:</u>
y - y1 = m(x - x1)
This is where (x1, y1) is a point the line intersects, and m is the slope.
<u>Plugging in the slope, we'll have:</u>
y - y1 = 2(x - x1)
We also know it intersects the point (-4, -1）
We can plug this into our equation as well.
y - (-1) = m(x - (-4))
y+1=2(x+4)
<u>Now, we can simplify it into slope-intercept form:</u>
y+1=2(x+4)
Distribute
y+1=2x+8
Subtract 1 from both sides
y=2x+8-1
y=2x+7
Answer:
Step-by-step explanation:
The diameter of the circle is 6mm
Circumference formula
C=pi d
18.84mm=3.14(d)
Divide by 3.14 to isolate for x
18.84mm/3.14=d
D=6m
