Answer:
4
Step-by-step explanation:
Do you see f(x) (f of x)? if the (x) part is a number, plug that number in as x on the other side of the equal sign. If I plug 1 in, I get 4, because the square root of 1 is 1, and 1+3=4.

If 15x + 20=a(bx + c), where a, b and c are integers, and a > 1,what is
the value of a? 3, 4, 5, 10, or 15
Since a > 1, b cannot be greater than 15, hence the value of a can be 3, 4, 5, and 10
Given the expression 15x + 20=a(bx + c),
To get the value of a, we will need to factor out the given expression as shown:
15x + 20=a(bx + c)
15x + 20=abx + ac
Comparing both sides
15x = abx
15 = ab
a = 15/b
Since a > 1, b cannot be greater than 15
Hence the value of a can be 3, 4, 5, and 10

(2x - 3)(5x^2 - 2x + 6) = (3x-2)(5x^2 - 2x + 6)
ANSWER AND EXPLANATION:
Answer:
FalseStep-by-step explanation:
Solution 1The easy way is to compare the leading terms or constants.
LHSThe leading term is:
2x*5x² = 10x³The constant is:
(-3)*6 = -18RHSThe leading term is:
3x*5x² = 15x³The constant is:
(-2)*6 = -12We see both the leading terms (10x³ ≠ 15x³) and constants (-18 ≠ -12) are different so the equation is false.
Solution 2We see one of the factors is same on both sides:
5x² - 2x + 6The other factors are:
2x - 3 = 3x - 2Since this factor is different on both sides, the equation is false
False
How?
Let 5x^2-2x+6 be A
The expression will be

Find the slope of a line if it goes through (2, 5) and (-2,9)
Hello!
The slope of a line is found using the following formula:
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
[tex]m=\frac{9-5}{-2-2}[/tex]
[tex]m=\frac{4}{-4}\\m=-1[/tex]
So the slope is -1.

Step-by-step explanation:
rewriting the third equation
[tex]4x - y + z = - 5 \\ - x + y - z = 5 \\ 2x - y - z = 1[/tex]
add to second equation to the first
[tex]4x - y + z = - 5 \\ + (- x + y - z )= 5 \\ = 3x = 0 \\ x = 0[/tex]
[tex] - y + z = - 5 \\ y - z = 5 \\ - y - z = 1[/tex]
I add third equation to the second
[tex]y - z = 5 \\ + ( - y - z) = 1 \\ = - 2z = 6 \\ z = - 3[/tex]
substitute z = -3 into either one of the other two equations and solve for y

The quotient of a number and 4 is less than -1.
Answer:
inequality: n/4 < -1
n < -4
Step-by-step explanation:
1. "The quotient of a number and 4" means that we're dividing a number, n, by 4: [tex]\frac{n}{4}[/tex]. "Less than -1" means that we have to use the < (less than) sign and put -1 after it. When we put these terms in a quantity, they look like this: [tex]\frac{n}{4} < -1[/tex].
2. Now, let's solve the inequality above.
Step 1: Multiply both sides by 4.
[tex]\frac{n}{4}*4 < -1 * 4[/tex] [tex]n < -4[/tex]Therefore, the inequality is n/4 < -1, and the solution to that inequality is n < -4.

Step-by-step explanation:
what fraction of a clockwise revolution does the hour of a clock turn through when it goes from a) 4 to 7 b) 8 to 2 c) 1 to 10
Answer:
a) 3/12 = 1/4
b) 6/12 = 1/2
c) 9/12 = 3/4
Step-by-step explanation:
To find the distance traveled by the hour hand, subtract the beginning position from the ending position. For example, in a, the distance traveled between 4:00 and 7:00 is three hours. Since there are 12 total hours on a clock, the fraction would be 3/12 (traveled/whole revolution). Simplify further to get 1/4.
The other two problems are very similar to the explanation above. Treat the second problem's ending time as 14:00, since it is two hours after 12:00.

I used a calculator, pls let me know if im incorrect
The given expression 5x(x−2)+6x−3(x²−7) will be equivalent to 2x²- 4x + 21. The correct option is D.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given expression is 5x(x−2)+6x−3(x²−7). The expression will be solved as below:-
E = 5x(x−2)+6x−3(x²−7)
E = 5x² - 10x + 6x - 3x² + 21
E = 2x² - 4x + 21
Therefore, the given expression 5x(x−2)+6x−3(x²−7) will be equivalent to 2x²- 4x + 21. The correct option is D.

explain how the inverse and the contopositivve of a conditional are alike and how they are different
Answer:
See explanation!
Step-by-step explanation:
The contrapositive of a conditional is similar to, yet different from, the inverse of the conditional.
The best way to explain this is to create an example. You should start by creating a conditional; you can then form the conditional's inverse and contrapositive.
Here is an example:
Conditional: If C, then D. (starting statement)
Inverse: If not C, then not D. (opposite of the conditional)
Contrapositive: If not D, then not C. (reversed opposite of the conditional)
Based on the information from the example, you can conclude:
Primary Similarity:
Both the contrapositive and the inverse are opposites of the conditional (both contain not, implying something would not happen under the given circumstances, rather than something would happen under those circumstances).
Primary Difference:
The contrapositive is a reversed version of the inverse; this causes them to most commonly have different meanings.
I am sure you could find more similarities/differences, but these were the two that stood out to me the most!

What is the domain and range of the function?
Domain:
Answer:
Domain: {x∈R}
Range: {f(x)∈R | f(x) ≥ 0}
Step-by-step explanation:
The domain of a function is, in simple terms, all the possible x values of a function (input values), and as the graph shows that all x values are possible (x, 0 and -x) meaning x can be any rational number, represented by the R and the subset symbol (∈).
The range is all the possible f(x) values (outputs/y values) and if you look at the graph you see that it isn't possible for the f(x)/output/y values to be negative so we write:
{f{x}∈R (f(x)/output/y value is rational) | (and) f(x) ≥ 0 (f(x)/output/y value is bigger or equal to 0, not negative)}
Hope I helped :)
