Question 2
Indicate the answer choice that best completes the statement or answers the question
Find.x
Answer:
C. 6√55
Step-by-step explanation:
The triangle given is an isosceles triangle that is divided into two equal parts by a segment.
Thus, we can apply pythagorean theorem to find x.
x = 2 × √(24² - 9²)
x = 2 × √495
x = 2 × √(9 × 55)
x = 2 × 3√55
x = 6√55
Consider the function f(x) = x^2 - 6x + 5
a. What are the x-intercepts of the function?
b. Does the function have a line of symmetry? if so, what is it?
c. Does the function have a maximum or minimum value? Explain how you know without graphing.
Answer:
Step-by-step explanation:
a. the question can be factored as (x-5)(x-1) so the 2 x intercepts are 5 and 1
b. yes the function has a line of symmetry every parabola does and it is at when x is 3
x. the function has a minimum value because the equation has x^2 which is 1x^2 1 is a positive meaning that the function opens upward which means it has a minimum value
Answer:
A)
(1, 0) and (5, 0)
B)
Yes.
The equation is x = 3.
C)
Yes.
In this case, we have a minimum.
Step-by-step explanation:
We are given the function:
[tex]f(x)=x^2-6x+5[/tex]
Since the highest degree is two, we can immediately determine this to be a quadratic.
A)
The x-intercepts of a function are whenever the function equates to 0. Hence:
[tex]0=x^2-6x+5[/tex]
We can factor:
[tex](x-1)(x-5)=0[/tex]
Zero Product Property:
[tex]x-1=0\text{ or } x-5=0[/tex]
Solving yields:
[tex]x=1 \text{ and } x=5[/tex]
So, our x-intercepts are at (1, 0) and (5, 0).
B)
Since this is a quadratic, it indeed has a line of symmetry.
Recall that the line of symmetry for a quadratic equivalent to the x-coordinate of the vertex.
In the given function, a = 1, b = -6, and c= 5.
Hence, the x-coordinate of the vertex is:
[tex]\displaystyle x=-\frac{b}{2a}=-\frac{(-6)}{2(1)}=\frac{6}{2}=3[/tex]
So, the line of symmetry is x = 3.
C)
Every parabola has a minimum/maximum value.
This depends on the sign of the leading coefficient.
If the leading coefficient is positive, then we have a minimum since our parabola will be curving upwards.
And if the leading coefficient is negative, then we have a maximum since our parabola will be curving downwards.
Since our leading coefficient here is 1, hence positive, we have a minimum value.

Step-by-step explanation:
Answer:
y= -5x+8
Step-by-step explanation:
So frstt you gotta know the form
y= mx+b
y= random Y-coordinate (not useful in this situation)
m= slope
x= random X coordinate (not useful in this situation)
b= y-intercept (the first point of the line that hits the y axis)
So first lets find the slope
sure we can use the slope formula between 2 points but I just did rise over run since this is an easy graph
Rise 5 and go Left 1 so the slope is -5/1 or -5 (negative due to the run going left instead of right plus the line is negative since its falling from left to right)
The y intercept is 8 becuase its the first point where the line crosses the Y axis
ANd thats it!
Plug it in
y= -5x+8

Solve for x 3 x − 8 = 6 x − 2
Answer:
x = -2
Step-by-step explanation:
3x - 8 = 6x - 2
Isolate x.
3x = 6x - 2 + 8
3x - 6x = 6
-3x = 6
x = 6 ÷ -3

Answer:
3) ? = 21
4) ? = 6
Step-by-step explanation:
3) The given ratio is ...
A : B = 2 : 7
You want to find ? such that ...
2 : 7 = 6 : ?
The ratio is equivalent when both numbers are multiplied by the same value.
From your knowledge of multiplication tables, you know that 2×3 = 6. then 7×3 = ? = 21.
__
4) For this one, you need to recognize that the given number corresponds to B.
A : B = 2 : 3
2 : 3 = ? : 9
Again, you know that 3×3 = 9, so 3×2 = ? = 6.

Find the slope. Pls help with 1. and 2. will give brainliest!!
Answer:
1. m = 1
2. m = 0
Step-by-step explanation:
[tex]m = \frac{y \frac{}{2} - y \frac{}{1} }{x \frac{}{2} - x \frac{}{1} } [/tex]
m = slope
To know the slope you need only 2 points of the line.
1.-
[tex]m = \frac{4 - ( - 1)}{2 - ( - 3)} \\ m = \frac{4 + 1}{2 + 3} \\ m = \frac{5}{5} \\ m = 1[/tex]
2.-
[tex]m = \frac{3 - 3}{2 - 0} \\ m = \frac{0}{2} \\ m = 0[/tex]

Answer:
solve for X
17-4x=33
-4x=33-17
-4x=16
-4x/-4=16/-4
x=-4
Step-by-step explanation:
1. move the constant (17) to the right side
2. subtract the numbers on the right side (33-17)
3. Divide both sides of the equation by -4 (/4)
4. write the answer x= -4

The sum of ages of two ship 12years old .Two years ago, the age of the older ship was three times the age of the newer ship. Find the present age of each ship.
Answer:
the present age of the old ship is 8 years
The present age of the new ship is 4 years
Step-by-step explanation:
Let the age of the older ship be x
Let the age of newer ship be y
If the sum of ages of two ship 12years old, then;
x + y = 12 .... 1
Two years ago;
Older ship age = x - 2
New ship age = y - 2
If two years ago, the age of the older ship was three times the age of the newer ship, then;
x - 2 = 3(y-2)
x-2 = 3y - 6
x = 3y - 4 ....2
Substitute equation 2 into 1;
From 1; x+ y = 12
3y-4+y = 12
4y = 12 + 4
4y = 16
y = 4
Since x+y = 12
x = 12-y
x= 12-4
x = 8
Hence the present age of the old ship is 8 years
The present age of the new ship is 4 years

What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
