If f(x) =X +3, what is the value of f(3) and f(-2)?
Use the Distributive Property to complete the equivalent expression.
4(y – 3) = _y - _
Answer:
4y - 12
Step-by-step explanation:
4(y-3)
4 x y= 4y
4 x -3 = -12
4y - 12
Consider the quadratic function, f(x)=-2x^2+12x+32=0. Select all statements that are true for the function. The value of the discriminant is -112. The value of the discriminant is 20. The value of the discriminant is 400. The function has 1 real solution. The function has 2 real solutions. The function has 2 complex solutions.
Answer:
Step-by-step explanation:
-2x² + 12x + 32 = 0
discriminant = 12² - 4(-2)(32) = 400
positive discriminant means there are two distinct real roots
x = [-12 ± √(12² – 4(-2)·32)] / [2·(-2)]
= [-12 ± √400] / (-4)
= [-12 ± 20] /(-4)

Which graph represents a geometric sequence? On a coordinate plane, 5 points are plotted. The points are (1, 1), (2, 3), (3, 5), (4, 7), (5, 9). On a coordinate plane, 4 points are plotted. The points are (1, 1), (2, 2), (3, 4), (4, 8). On a coordinate plane, 3 points are plotted. The points are (1, 2), (4, 4), (9, 6). On a coordinate plane, 3 points are plotted. The points are (1, 1), (2, 4), (3, 9).
Answer:
Graph B is the correct answer. Just in case it is not choice B for you, it's the graph with points (1,1), (2,2), (3,4), and (4,8) in that order. Sadly, the other guy is incorrect and you should not listen to him.
Step-by-step explanation:
The graph that represents a geometric sequence is (b) (1, 1), (2, 2), (3, 4), (4, 8)
What is a geometric sequence?A geometric sequence is a sequence that has a common ratio
The common ratio of a geometric sequence is calculated as:
[tex]r = \frac{y_2}{y_1}[/tex]
Using the above rule, we have:
[tex]r = \frac{2}{1} = \frac 42 = \frac 84[/tex]
[tex]r =2 =2 =2[/tex]
The above represents option B, and it has a common ratio of 2
Hence, the graph that represents a geometric sequence is (b) (1, 1), (2, 2), (3, 4), (4, 8)

Step-by-step explanation:
Kayla is thinking of a 3-digit number.
* It is divisible by 18.
* It is a palindrome (It reads the same left-to-right as it does right-to-left, like 252 and 848).
* It is one less than a multiple of 5.
What is Kayla’s number?
Answer:
kaylas thinking of the number 414
Step-by-step explanation:
414 is divisable by 18 (414 divided by 23)
414 is palindrome
414 is one less than a multiple of 5 (415)
Answer:
414
Step-by-step explanation:
The last digit must be 4 or 9 since it is one less than a multiple of five. Then, it says the number must be divisible by 18, and 18 = 2x9. Only 4 is divisible by 2, so four must be the last digit. Since it's a palindrome, the first digit must also be four. Since it also has to be divisible by nine, 4 + 4 = 8, and 8 + 1 = 9.

Nelda needs to wrap a holiday gift box. The box is in the shape of a rectangular prism with the dimensions shown.
Answer:
416 in²
Step-by-step explanation:
Given that:
Height. h = 4 in
Length = 12 in
Width = 10 in
The surface area of a rectangular prism is obtained using the relation :
Surface Area, S = 2(lw + lh + wh)
S = 2[(10*12) + (10*4) + (12*4))
S = 2(120 + 40 + 48)
S = 2(208)
S = 416 in²
