Answer:

I think that you need to plug 7 in to the x's

Step-by-step explanation:

Yes it looks very weird, but if you don't think that is right, Use the 7 for the F's.

One of them should come out right. :3

Answer:

154

Step-by-step explanation:

The expression is  f(x)=4x^2-7x+7 and we know that  f(x)=f(7). Therefore, you will have to substitute x with 7.

<u>Calculations:</u>

f(x)=4x^2-7x+7

f(7)=4(7)^2-7(7)+7

4(49)-49+7= 154

The answer is the third one (C?) because if you started at 0, you are going below it since you are losing yards, causing you to have less and less yards. Adding two negatives gives you a lesser amount.

Answer:

15% = 3/20 = 0.15

1.25 =125% =5/4

12 3/8 = 12.375 = 1237.5%

Step-by-step explanation:

15% to fraction , then decimal ;

15\% = \frac{15}{100} \\Cross\:cancel\:common\:factor ; 5\\\\15\div 5 = 3\\100\div 5 = 20\\\\= \frac{3}{20}\\\\\frac{3}{20} = 0.15

1.25 to fraction , then percentage

1.25 = \frac{1.25}{1}  \times \frac{100}{100} \\\\1.25\times 100 =125\\1\times 100 = 100\\\\= \frac{125}{100} \\= \frac{5}{4} \\\\1.25\times 100\\= 125\%

12 3/8 to decimal then percentage

12\frac{3}{8} =\frac{99}{8} = 12.375\\\\12.375\times 100\\\\= 1237.5\%

Please need urgent help. It's my final question. I'll have be brainliest!!

X=32

All triangles add up to 180 degrees so if the right angle is 90 degrees then you have 90 degrees left. Next, you take the 2x and x-6 and plug them into the equation 3x-6=90. Once you solve that you get x=32.
