♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

$y =f(x) = - 2x + 4$

_________________________________

$f( - 4) = - 2( - 4) + 4$

$f( - 4) = 8 + 4$

$f( - 4) = 12$

_________________________________

$f(0) = - 2(0) + 4$

$f(0) = 0 + 4$

$f(0) = 4$

_________________________________

$f(5) = - 2(5) + 4$

$f(5) = - 10 + 4$

$f(5) = - 6$

_________________________________

Range = { 12 , 4 , -6 }

Thus the correct answer is (( A )) .

ANSWER

Find out the expression gives the percent of survey participants who chose swimming.

To proof

As given

75 girls at a summer camp were asked to complete a survey about their favorite outdoor activity.

27 girls chose swimming

32 girls chose hiking.

FORMULA

$Percentage = \frac{Part\times100}{whole}$

total girls = 75

girls chose swimming = 27

put in the formula

$= \frac{27\times100}{75}$

= 36%

36% of survey participants who chose swimming

Hence proved

Answer:

7. x = 3

Step-by-step explanation:

To find the value of x, use the triangle sum property. Every triangle has interior angles which add to 180 degrees. To solve, add the expressions and numbers together then set equal to 180. Then use inverse operations to solve for x.

7. 20x - 9 + 10x + 9 + 90 = 180 Subtract 90 from both sides.

20x - 9 + 10x + 9 = 90 Add -9 + 9 = 0

20x + 10x = 90 Add like terms 20x + 10x = 30x

30x = 90 Divide both sides by 30.

x = 3

Repeat this process for each problem.

PLEASE HELP GONNA FAIL WILL GIVE BRAINLESS

Answer: P = 166 units

Step-by-step explanation: Each point on the triangle has lines that are tangent to the circle in the triangle, meaning that those lines form a 90° angle to the middle point in the circle. There is also a rule that states if there are tangent lines coming from the points and if the points have at least one given side length, the other side will have the same side length. So if one side on point D is 41, then the other side connected to the point is 41. I added up all of the side lengths; 41 + 41 + 30 + 30 + 12 +12 = 166 units.

I hope this helps!
