When we can't simplify a root under variable further or we can't remove the root sign that is called surd.It may be a square root or cube root or n th root .They are especially called irrational numbers.
Ex:-
[tex]\\ \rm\longmapsto \sqrt{9}=3[/tex]Hence its not a surd.
but
.
[tex]\\ \rm\longmapsto \sqrt{3},\sqrt{7}[/tex]Are surds.
There are six types of surds such as :

Find f(-5)
Answer:
25
Step-by-step explanation:
f(x)=-x^2-10x
Let x = -5
f(-5)=-(-5)^2-10(-5)
= -25+50
=25

John is printing advertisement flyers for his business on colored sheets of paper. There
are 500 sheets of paper in one ream and a toner cartridge will print 2,000 sheets. John
has 3 toner cartridges and 15 reams of paper. Which will he run out of first?
Answer:
John will run out of toner cartridges first
Step-by-step explanation:
First, find how many sheets he can print with the 3 toner cartridges:
3(2000)
= 6000 sheets of paper
Find how many sheets of paper he has:
15(500)
= 7500 sheets of paper
Since 6000 is less than 7500, John will run out of toner cartridges first.
3/4x + 4/7y = 5/4x -1...solve for y
Answer:
[tex] \frac{3}{4} x + \frac{4}{7} y = \frac{5}{4} x - 1 \\ \frac{4}{7} y = \frac{5}{4} x - 1 - \frac{3}{4} x \\ \\ \frac{4}{7} y = \frac{5x - 4 - 3x}{4} \\ \frac{4}{7} y = \frac{2x - 4}{4} \\ \\ y = \frac{2x - 4}{4} \div \frac{4}{7} \\ y = \frac{2x - 4}{4} \times \frac{7}{4} \\ \\ y = \frac{14x - 28}{16} \\ \\ y = \frac{14x}{16} - \frac{28}{16} [/tex]

On Saturday, you bowl at Mar vista Bowl, where renting shoes costs $2 and each game bowled is $3.50. On Sunday, you bowl at Pinz where the shoe rental is $5 and each game bowled is $3.25. If you spent the same amount each day, how many games,g, were bowled?
Answer:
12 gamesStep-by-step explanation:
Let the number of games is g
Total cost at Mar Vista:
3.5g + 2Total cost at Pinz:
3.25g + 5Since same amount spent in both places, we have:
3.5g + 2 = 3.25g + 53.5g - 3.25 = 5 - 20.25g = 3g = 3/0.25g = 12Answer:
12
Step-by-step explanation:
Let the game be x
3.5x + 2 = 3.25x + 5
3.5x - 3.25x = 5 - 2
0.25x = 3
x = 3/0.25
x = 300/25
x = 12

if hj=7x-27 find the value of x
Answer:
x=7
Step-by-step explanation:
HI + IJ = HJ
3x-5 + x-1 = 7x-27
Combine like terms
4x-6 = 7x-27
Subtract 4x from each side
4x-6 -4x= 7x-27-4x
-6 = 3x-27
Add 27 to each side
-6+27 = 3x-27+27
21 = 3x
Divide by 3
21/3 = 3x/3

4. Determine both the HCF and LCM of 25 and 200
Answer:
The LCM of 25 and 200 is 200.
Explanation:
Find the prime factorisation of 25
25 = 5 × 5
Find the prime factorisation of 200
200 = 2 × 2 × 2 × 5 × 5
Multiply each factor the greater number of times it occurs in steps 1 or 2 above to find the LCM:
LCM = 2 × 2 × 2 × 5 × 5
LCM = 200
Answer:
the HCF of 25 and 200 is 25 because it divides both of them and is maximum factor of them.
LCM of 25 and 200 is 200 because it can be divided by both 200 and 25
Which statement describes the graph of f(x) = –4x3 – 28x2 – 32x + 64?
The graph crosses the x-axis at x = 4 and touches the x-axis at x = –1.
The graph touches the x-axis at x = 4 and crosses the x-axis at x = –1.
The graph crosses the x-axis at x = –4 and touches the x-axis at x = 1.
The graph touches the x-axis at x = –4 and crosses the x-axis at x = 1.
It should be noted that a statement that describes the graph of f(x) = -4x3 - 28x2 - 32x + 64 will be;
D. The graph touches the x-axis at x = -4 and crosses the x-axis at x = 1.
What is a graph?It should be noted that a graph is a diagram that shows the relationship between two or more sets of numbers.
Given that;
The function is,
⇒ f(x) = - 4x³ - 28x² - 32x + 64
Now, We can draw the graph of the function,
We get;
The x-axis at x = -4 and crosses the x-axis at x = 1.
In this case, the statement that describes the graph of f(x) = -4x3 - 28x2 - 32x + 64 will be is that the graph touches the x-axis at x = -4 and crosses the x-axis at x = 1.

Hi! I'm happy to help!
For our equation, we need to find out what our two smaller equations are.
We can see that angle HGF is our largest angle, and it is composed of EGF, and HGE. We can insert our values into an equation to solve:
16x+4=110+3x+11
We can then combine like terms:
16x+4=121+3x
To solve for x, we need to put it by itself on one side of the equation. So, let's subtract 4 from both sides:
16x=117+3x
Now, let's subtract 3x from both sides:
13x=117
Now, let's divide both sides by 13 to solve for x:
x=9
Now, we know that x=9.

A. quadratic; y = –2.5x2
B. linear; y = 2.5x
C. exponential; y = 2.5x
D. quadratic; y = 2.5x2
Answer:
D. quadratic; y = 2.5x2
Step-by-step explanation:
Answer:
A. quadratic; y = 2.5x2
Step-by-step explanation:
Answer:
Option (1)
Step-by-step explanation:
x -2 -1 0 1 2
y 10 2.5 0 2.5 3.0
Ist difference,
= -2.5
= 2.5
= 7.5
2nd difference,
= 5
= 5
= 5
Since 2nd difference is common, given table represents a quadratic equation.
Let the equation is,
y = ax²+ bx + c
For a point (0, 0) passing through the quadratic equation,
0 = c
Therefore, quadratic equation is y = ax² + bx
Since ordered pair (-1, 2.5) passes through the graph of the function,
2.5 = a(-1)² + b(-1)
a - b = 2.5 ------(1)
For another point (1, 2.5)
2.5 = a(1)² + b(1)
a + b = 2.5 ------(2)
By adding equations (1) and (2),
2a = 5
a = 2.5
and from equation (2)→ y = 0
Therefore, equation of the quadratic function given in the table is y = 2.5x²
