Traffic rules are set by each individual state.

In most states, an intersection where traffic lights are out of order
is treated as if it were a 4-way STOP.

But you can't depend on this answer. You MUST determine what
the law is in the state where you're driving. And if you drive out of
state, it may change for you.

Treat the outage of the traffic lights like a stop sign.

Triangle ABC has vertices A(–2, 3), B(0, 3), and C(–1, –1). Find the coordinates of the image after a reflection over the x-axis

slava [35]

Answer:

(-2,-3), (0,-3), (-1,1)

Step-by-step explanation:

When reflecting over an axis, the axis you are reflecting over stays the same while the opposite axis becomes its opposite number, like reflect (12, -9) over the y axis, the y (-9) would stay the same but the x (12) would become (-12)

What is the area of number 4?

Tanzania [10]

Answer:

Step-by-step explanation:

Look at the picture.

We have three rectangles. The formula of an area of a rectangle:

$A=lw$

l - length

w - width

Rectangle I:

$A_I=7\cdot20=140\ cm^2$

Rectangle II:

$A_{II}=6\cdot20=120\ cm^2$

Rectangle III:

$A_{III}=18\cdot30=540\ cm^2$

The area of number 4:

$A=A_{I}+A_{II}+A_{III}$

Substitute:

$A=140+120+540=800\ cm^2$

Which equation describes a line with a slope of -8 and includes the point (-4, 7)?

timurjin [86]

Such an equation would be y + 8x = - 25 (standard form) OR y = -8x - 25 (y-intercept form)

Deriving The Answer:

By using the point-slope form of the equation of a line, by knowing the gradient of that line and a point on that line, the equation of this line can be derived.

Now, the point-slope form exists as y - y₁ = m ( x - x₁)

since slope = -8 and the point on the line = (-4 , 7)

Then m = - 8
x₁ = - 4
y₁ = 7
⇒ y - 7 = -8 ( x - (-4))

⇒ y - 7 = -8x - 32

⇒ y + 8x = - 25

Find the center, vertices, and foci of the ellipse with equation x^2/100+y^2/64 = 1.

Amiraneli [1.4K]

X^2/a^2+y^2/b^2=1

a^2=100 a=10
b^2=64 b=8

c^2=a^2-b^2
c=6
