The value of the function for x = -1 is 19.
Given is a function f(x) = 3x² + 16 we need to find f(-1),
To find f(-1), we substitute -1 into the function f(x) and evaluate the expression.
Let's do that:
f(x) = 3x² + 16
Substituting x = -1:
f(-1) = 3(-1)² + 16
Simplifying:
f(-1) = 3(1) + 16
f(-1) = 3 + 16
f(-1) = 19
Therefore, f(-1) is equal to 19.

Darpana solved the equation s = StartFraction a + b + c Over 3 EndFraction for a. Her steps are shown below: 1. Multiply by 3: s = StartFraction a + b + c Over 3 EndFraction. 3 s = a + b + c. 2. Subtract b: 3 s minus b = a + b + c minus b. 3 s minus b = a + c. 3. Divide by c: StartFraction 3 s minus b Over c EndFraction = a. Which statement about Darpana's work is true? In step 1 she needed to divide by 3 rather than multiply. In step 2 she needed to add b rather than subtract. In step 3 she needed to subtract c rather than divide. Darpana solved the equation correctly.
Answer:
Option (c) is correct.
Step-by-step explanation:
Given equation is :
[tex]s=\dfrac{a+b+c}{3}[/tex]
The equation can be solved for a as follows :
Step 1.
Cross multiply the given equation
[tex]3s=a+b+c[/tex]
Step 2.
Now subtract b on both sides
3s-b = a+b+c-b
3s-b = a+c
Step 3.
Subtract c on both sides
3s-b-c=a+c-c
⇒ a=3s-b-c
The statement that is true for Darpana is " In step 3, she needed to subtract c rather than divide".
Answer:
the correct answer is c

Show that 3 · 4n + 51 is divisible by 3 and 9 for all positive integers n.
Answer:
4^1 + 17 = 21 , which is divisible by 3. 4^k + 17 and 3 * 4^k are both divisible by 3, so 4^k + 17 + 3 * 4^k is divisible by 3 as well. 3 * (4^n + 17) would be divisible by 9
Someone please help me asap. I’m confused and need help. Complete the table using the function n = 9b + 19
answer: you would just substitute all of the values you see for b into the equation where there's a b
Answer:
55; 64; 73
Step-by-step explanation:
In the table, they provide a b value. Basically, you plug in the value of b they give you into the expression n = 9b + 19
if b = 4:
n = 9(4) + 19
n = 36 + 19
n = 55
if b = 5:
n = 9(5) + 19
n = 45 + 19
n = 64
if b = 6:
n = 9(6) + 19
n = 54 + 19
n = 73
Check your work with the last numbers in the table. They say the value of n = 82 when b = 7 so try it
if b = 7:
n = 9(7) + 19
n = 63 + 19
n = 82
Work is correct

The difference of a number and 6 is the same as 5 times the sum of the number and 2. What is the number?
A. -4
B. -2
C. -1
D. 1
Answer:
The answer would be A. -4
Step-by-step explanation:
If you right it out like x-6=5(x+2), then you distribute the 5, you get: x-6=5x+10. Then subtract x from both sides, you get: -6=4x+10. Subtract 10 from both sides, you get: -16=4x. The all you have to do is divide both sides by 4, and you get: -4=x

Answer this question showing work. 2b − 7 ≥− 14 + 2b
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
First you write out your inequality:
[tex]2b-7\geq -14+2b[/tex]
So first we will subtract 2b on both sides:
[tex]-7\geq -14[/tex]
Since they both canceled out each other we are now left with [tex]-7\geq -14[/tex]
So anyways let's add 7 to both sides:
[tex]0\geq -7[/tex]

x3-8= 0
Step-by-step explanation:
x^3-8 = 0
or, x^3 = 8
or, x = 8×(1/3)
or, x = 2
All solutions to the equation are x = 2, -1 + i√3, and -1 - i√3 two roots are complex and one root is real.
What is a complex number?It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.
We have:
x³ - 8 = 0
Using identity:
a³ - b³ = (a - b)(a² + ab + b²)
(x - 2)(x² + 2x + 4) = 0
x = 2
x² + 2x + 4 = 0
Using quadratic formula:
[tex]\rm x = \dfrac{-2 \pm\sqrt{2^2-4(1)(4)}}{2(1)}[/tex]
x = -1 ± i√3
Thus, all solutions to the equation are x = 2, -1 + i√3, and -1 - i√3 two roots are complex and one root is real.
