Answer:
-105
Step-by-step explanation:
hello there!
f(x)= -x^2+8x
f(-7)= -(-7)^2 + 8*(-7)
= - 49 + (-56)
= -105
hope it helps!
thank u!
<span>Experimental Probability is the ratio of the number of times an event occurs to the total number of trials.
Given that </span><span>Cole
rolls a number cube multiple times and records the data in the table below. At the end of the experiment, he counts that he has rolled 190
fours.
From the table, we see that the total number of trials is 1,000 and there are 190 fours.
Therefore, the experimental probability of rolling a four, based on
Cole’s experiment is given by 190 / 1,000 = 0.19 = 0.190 to the nearest thousandth.</span>
Answer:
36 cm
Step-by-step explanation:
The formula to find the area of a triangle is A=1/2bh where b stands for base and h for height.
So, 8 times 9 equals 72, and 72 divided by 2 is 36.
3 + 4abs(x/2 + 3) = 11 Subtract 3
4 abs(x/2 + 3) = 11 - 3
4 abs(x/2 + 3) = 8 Divide by 4
abs(x/2 + 3) = 8/4
abs(x/2 + 3) = 2
Solution 1
x/2 + 3 = 2 Subtract 3
x/2 = 2 - 3
x/2 = - 1 Multiply by 2
x/2 *2 = - 2
x = - 2
Solution 2
x/2 + 3 = - 2
x/2 = - 2 - 3
x/2 = - 5 Multiply by 2
x = -5 * 2
x = -10
Solutions
x = - 2 <<<< answer 1
x = -10 <<<< answer 2
Answer:
Yes, because -43 can be turned into a fraction. Ex. -43/1.
