4 0

Answer:

Step-by-step explanation:

They are testing whether you remember the basic 30,60,90 degree triangle side relationship. The ratio of sides for this triangle are 1 opposite the 30 degree angle, square root of three opposite the 60 degree angle and a hypotenuse of 2 opposite the 90 degree angle.

x/2=2/1

x=4/1=4

bottom answer choice

x/4=3^(1/2)/1

x=4(3^(1/2))

third answer choice

What is the value of f(7)
kkurt [141]
F(7) means f(x) when x = 7. The x is replaced with 7.

So we'll replace every x with 7 to go from x = 7 to 3-x = 3-7 = -4

Put another way
f(x) = 3-x
f(7) = 3-7
f(7) = -4

Answer: -4

What is the scale factor of this dilation?
Montano1993 [528]

Answer:

<h2>Three-fourths</h2>

Step-by-step explanation:

<h3>Triangle XYZ</h3>

XY=10\\ZY=12\\ZX=8\\

<h3>Triangle X'Y'Z'</h3>

X'Y'=7.5\\Z'Y'=9\\Z'X'=6

To find the factor of dilation, we just need to divide the sides of the prime figure with the sides of the original figure.

\frac{10}{7.5}= 1.333333333..\\\frac{12}{9}=1.333333...\\ \frac{8}{6}=1.3333333....

Notice that 1.333333.... is equivalent to 4/3, but the factor of dilation is from the smaller figure to the bigger figure. That means it's the opposite: 3/4.

Therefore, the factor of dilation is three-fourths.

10 POINTS WILL MARK BRAINLIEST <br>Find the restriction on y=2x^2-8
borishaifa [10]
X cannot equal +2, and can't be -1. If you factor it, then you notice you get 2(x+2)(x-2). If you use either one for the x, one will be zero and the won't, and vise-versa.

-3b-(-2)=4b-12 show work please ASAP
makvit [3.9K]

Solve the equation:

– 3b – (– 2) = 4b <span>– 12

</span>– 3b + 2 = 4b – 12

– 3b = 4b – 12 – 2

– 3b = 4b – 14

– 3b – 4b = – 14

– 7b = – 14

        – 14
b = ———
         – 7


b = 2   <———   solution.


I hope this helps. =)
