A)

Since we're dealing with an isoseles triangle you know that the bottom two angles are congruent (A&B).
Also you know that line CM creates a midpoint in line AB and also biscects angle C. There you have all three angles so D is out along with B. Now to Illiminate C we know that line CM is shared so that's one side, because line CM creates a mid point in line AB lines AM and BM are congruent so that's the second side and if we look at the triangle as one isoseles again we know that the two upper sides are congruent, that's the last side to illiminate C. Leaving us with A, the dont give us any measurements so you aren't able to look at the heights and lengths.

PLEASE HELP I RLLY DONT KNOW WHAT TO DO

Answer:

a) f(0) = -9

b) f(2) = -5

c) f(-3) = -15

d) f(1/2)=-8

Step-by-step explanation:

We are given the function $f(x)=2x-9$ and we need to find the following:

a) f(0)

For finding f(0) put x =0 in the given function

$f(x)=2x-9\\Put\:x=0\\f(0)=2(0)-9\\f(0)=-9$

So, we get f(0)=-9

b) f(2)

For finding f(2) put x =2 in the given function

$f(x)=2x-9\\Put\:x=2\\f(2)=2(2)-9\\f(2)=4-9\\f(2)=-5$

So, we get f(2)=-5

c) f(-3)

For finding f(-3) put x =-3 in the given function

$f(x)=2x-9\\Put\:x=-3\\f(-3)=2(-3)-9\\f(-3)=-6-9\\f(-3)=-15$

So, we get f(-3)=-15

d) f(1/2)

For finding f(1/2) put x =1/2 in the given function

$f(x)=2x-9\\Put\:x=\frac{1}{2}\\f(\frac{1}{2})=2(\frac{1}{2})-9\\f(\frac{1}{2})=1-9\\f(\frac{1}{2})=-8$

So, we get f(1/2)=-8

5n – 2n<br> I need help asap

blondinia [14]

Combining those like terms would end as 3n.

Explanation: The end of a subtraction equation is basically just the negative number, except you add it to the other part.

For example, 2n is really -2n, and you just add -2n to 5n (which is positive,) and you get 3n.

What value of a makes the equation true? 1.7a+0.3a=4/5 A) a=2/5 B) a=−1 1/5 C) a=2 4/5 D) a=1 3/5

7nadin3 [17]

First you want to collect the like terms, 2a=45 , then divide both sides of the equation by 2 which is a=2/5 , or a=0.4

Answer : 47 miles per hour
50 mph = 50*5280 ft / hour = 50*5280 / 3600 ft / sec 73.33 ft/sec so Morrius speed is 70.433 ft/sec in mph this is (70.33* 3600 )/ 5280 = 47 mph
