The y intercept is when x=0 so y=1/2(0) -3 so y=0-3 so y=-3

Hi there!
The y-intercept of the equation y = 1/2x - 3 is (0,-3).

This is because in the equation y=mx+b, the b represents the y-intercept. Since the equation of the line you were given is in y=mx+b form, you're able to easily find the y-intercept. When asked for the y-intercept, it is always best to give it as a point, you can use this - (0,y) - the y representing the y-intercept.

If there's anything else that I can help you with, please let me know! :)

sergiy2304 [10]

Answer:

Step-by-step explanation:

The letters are virtually impossible to read. I'll do my best, but recognize it is why you are not getting answers. I take y to be next to the 100 degree angle and part of the triangle.

I take x to be to the left of y. It is equal to the 28o angle because of the tranversal properties.

Finally z is the exterior angle of the triangle and as such has properties of z = y + 28 where y and 28 are remote interior angles to the triangle.

so x = 28 because of the transversal cutting the two parallel lines. They are equal by remote exterior angles of parallel lines.

y = 180 - 100 - 28 = 52

Finally z = 52 + 28 = 80 degrees because x and y add to 80 degrees.

If the assumptions are incorrect, could I trouble you to repost the diagram or correct the errors I  have made.

Which Two Numbers Add Up To Negative 26 And Multiply To 11?
Fynjy0 [20]
Xy=11
x+y=-26


x+y=-26
minus x both sides
y=-26-x

sub for y
x(-26-x)=11
-26x-x^2=11
add 26x+x^2 both sides
x^2+26x+11=0

ax^2+bx+c=0
x=\frac{-b+/- \sqrt{b^{2}-4ac} }{2a}


a=1
b=26
c=11

x=\frac{-26+/-\sqrt{26^{2}-4(1)(11)} }{2(1)}
x=\frac{-26+/-\sqrt{676-44} }{2}
x=\frac{-26+/-\sqrt{632} }{2}
x=\frac{-26+/-2\sqrt{158} }{2}
x=-13+/-\sqrt{158}

x=-13+\sqrt{158} or -13-\sqrt{158}

aprox

x=-0.420195 or -25.5698

those are the numbers

Question 3 (5 points)
luda_lava [24]

Answer:

width = 26 inches

Step-by-step explanation:

perimeter of a rectangle= p

p= 2*L+ 2*w

L= length

w= width

The statement tell us:

L= 10+w

p=124

124=2*(10+w) +2*w

124= 20+2w+2w

124-20=4w

w=104/4

w=26 =width
