Answer:
f(-2) = -12
Step-by-step explanation:
f(x)= x² + 8x
We want to find f(-2)
f(-2) = (-2)² + 8(-2)
Apply exponent : (-2)² = 4
f(-2) = 4 + 8(-2)
multiply 8 and - 2 : 8 * -2 = -16
f(-2) = 4 - 16
subtract 16 from 4 : 4 - 16 = -12
f(-2) = -12
Step-by-step explanation:
f(x) = x² + 8xf(-2) = (-2)² + 8(-2) = 4 - 16 = -12

Answer: Score on a science test, D, Average temperature
Step-by-step explanation:
A: Score on a science test(dependent variables are the "effects" of the independent variable, and number of hour studied results in the score on the science test)
B: D (the input will always remain the same but the output is dependent on the independent variable, so in this case the input is the independent variable)
C:Average temperature( the temperature depends on how far it is from the equator, thus making it the dependent variable in this relationship)
Hope it helps!

Your softball team is ordering equipment from a catalog. Each bat costs $42. The cost of shipping is $12 no matter how much you order. The total cost is $348. How many bats did your team order?
Can someone help me with this, and if you can Explain it.
Answer:
20
Step-by-step explanation:
Since C is the midpoint of BD, BC must be equal to CD. Therefore, we can set the equation:
x+4=3x-10
Solve:
14=2x
x=7
Then we find AC, which is:
2x-5+x+4 = 3x-1
We can plug x in to get:
3*(7)-1=20
The 13th arithmetic sequence of whose common difference is d=7 and first term is A1=3
Answer:
Step-by-step explanation:
a1 = 2
d = 7
n = 13
I take it you want the 13th term.
t_13 = a1 + (n - 1) * d
t_13 = 3 + (13 - 1) * 7
t_13 = 3 + 12*7
t_13 = 3 + 84
t_13 = 87

Step-by-step explanation:
The product two consecutive odd numbers is 63find the number
Answer:
These results, 7 and 9, have a product of 63, as stated.
Step-by-step explanation:
Represent the first odd number by x and the first consecutive odd number by x + 2. Then the product of these two numbers is x(x + 2) and it equals 63.
Solve for x. Perform the indicated multiplication, obtaining
x^2 + 2x - 63 = 0
Solve this by factoring: (x + 9)(x - 7) = 0
Then x could be either -9 or +7. If we let x = 7 then the first consecutive odd number is 7 + 2, or 9. These results, 7 and 9, have a product of 63, as stated.

What divided by 6 equals 0.41?
2.46
I think.
Because if you multiply 6 and 0.41 you get 2.46.
Answer:
2.46
Step-by-step explanation:
x/6=0.41
Multiply 6 on both sides and you get 2.46
express 60 as the product of prime factors in ascending order in
index form
Answer:
2 is a prime number so we don't need to break the 2's down any more. Instead we break 15 down. 15 doesn't divide by 2 so we try the next prime number: 3 Divide 15 by 3 to get 15 = 5 x 3, and so 60 = 5 x 3 x 2 x 2. Now we collect the factors, so our final answer is 60 = 5 x 3 x 22.

Find the recursive definition of the following sequence (Remember to define the first term t, the recursive rule to find tn,and the value n will start at) 120, 60, 20, 5, 1
Answer:
t[1] = 120; t[n] = t[n-1]/n, n ≥ 2
Step-by-step explanation:
The first two terms have a ratio of 1/2. The next two terms have a ratio of 1/3. The terms after that have a ratio of 1/4. It seems that the divisor increases as n increases. In fact, the n-th term is the previous one divided by n.
The first term is 120, so ...
t[1] = 120
Using the above-described rule, ...
t[n] = t[n-1]/n . . . . for n ≥ 2
What is the value of the expression 18-2 times ( 4 +3)
Answer:
1 2/7
Step-by-step explanation:
18 - 2x(4+3) =
combine like terms in the parentheses
18 - 2x(7) =
Multiply
18 - 14x (This is the value of the expression)
We can solve for x by setting it equal to zero
18 - 14x = 0
-14x = -18
x = -18/-14
x = 1 2/7
A shopkeeper orders a special brand of coffee powder to be delivered to

write the slope intercept form of the equation through (2,-4) parallel to y=-1
Answer:
y = -x - 2Step-by-step explanation:
Parallel lines have equal slopes.
Given slope, m = - 1 and point (2, -4).
Slope- intercept form:
y = mx + bTh line will be:
y = -x + bSubstitute x and y- values of the point into equation to find the value of b:
- 4 = - 2 + bb = 2 - 4b = - 2The line is:
y = -x - 2Slope=m=0
