Which point is an x-intercept of the quadratic function f(x)=(x-8)(x+9)
Step-by-step explanation:
An x-intercept of a function occurs when f(x) = 0.
In f(x) = (x-8)(x+9), f(x) will be 0 if either (x-8) is 0 or (x+9) is 0.
Hence, f(x) = 0 when x = 8 or x = -9.
Answer:
The answer is D. (-9,0) on edge

Round 7.21 to the nearest whole number.
Answer:
7.21 ≈ 7Step-by-step explanation:
If you are rounding to the whole number you are rounding to ones so you need to look at the tenth digit:
2<5 so 7 stays the same (rounding down)
7.21 ≈ 7
The nearest whole number for the given number is 7.
What is rounding off?To change a number into an approximation having fewer significant digits. For example :-
Round off 15.4 to 15, round off 15.51 to 15.5 or to 16, round off 0.499 to 0, and round off 970,000 to 1 million.
Given is a number 7.21,
We know that, if the digit is less than 5, round down and if the digit is 5 or more than 5, round up.
Since, numbers after the decimal is not greater than 5, therefore, it will not change and will remain 7.
Hence, the required whole number is 7.

O (-6,8).(-7,4), (-6, -7)
O (5,8), (3,4),(4,-7)
0 (-1, 13), (-2,9),(-1,-2)
Answer:
The right answer is 0 (-1, 13), (-2,9),(-1,-2).
Step-by-step explanation:
if (-1,8), (-2,4),(-1, -7) has already translated the domain, then all you need to do is add 5 to every range in the relation. To which will become (-1, 13), (-2,9),(-1,-2) .

Answer:
c. 10 cm
Step-by-step explanation:
The parallel sides of trapizium are the bases so
base 1(B1) =9cm , base(B2)= 12cm
[tex]area(a) = 105 {cm}^{2} [/tex]
the perpendicular distance means the height so lets find the height
area of trapizium= B1 + B2 × h
2
[tex] {105cm}^{2}(the \: given \: area) = \frac{9cm(the \: given \: base) + 12cm(the \: given \: base)}{2} \times h[/tex]
[tex] {105cm}^{2} = \frac{21cm}{2} \times h[/tex]
now we crisscross
[tex] {105cm}^{2} \times 2 = 21cm \times h [/tex]
[tex] {210cm}^{2} = 21cm \times h[/tex]
[tex] \frac{ {210cm}^{2} }{21cm} = \frac{21cm \: }{21cm} \times h[/tex]

Step-by-step explanation:
slope=(-2-7)/(3-0)=-9/3=-3
f(x)-7=-3(x-0)
f(x)=-3x+7
Take any two points .
I took (0,7) and (3,-2),then slope=(y2-y1)/(x2-x1)=(-2-7)/(3-0)=-9/3=-3
you can take any two points.
Let us take (-6,25) and (-3,16)
slope=(16-25)/(-3-(-6))=-9/(-3+6)=-9/3=-3
eq. of line is
y-y1=m(x-x1),here m=-3
y-25=-3(x-(-6))=-3(x+6)=-3x-18
y=-3x-18+25
y=-3x+7
Here y=f(x)

8x - 3 = 3x + 2
A. One solution
B. Infinite solutions
C. No solutions
please explain how you got it
A one solution because it's x=1
Step By Step explanation:this is the original problem
8x-3=3x+2
we want to have x by itself so. . .
we add three on both sides. it cancels -3. And 2+3=5
8x=3x+5
we subtract 3x on both sides so 8x-3x=5x and 3x cancels on the other side
5x=5
we divide by 5 on both sides to get x by itself
x=1
if it was 1=1 or x=x (the same on both side) it would've been infinite solutions. if the numbers didn't match like 4=6 it would've been no solution

what is the greatest common factor of 8 and 16
Answer: 8
Step-by-step explanation: Usually you should use prime factorization or the “ladder” method; however, with questions like this that have small, easy numbers, you can simply think about it. Every number’s largest factor is itself, which means that 8 is at least a factor of 8. We also know that 8 times 2 equals 16, hence, the greatest common factor is 8.
The perimeter of a square is 64 mm. Write and solve an equation to determine the length of each side of the square.

Consider this question:
-2x=x^2-6
1) Rewrite the question by completing the square. Your equation should look like (x+c)^2=d or (x-c)^2=d.
2) What are the solutions to the equation?
Answer:
see explanation
Step-by-step explanation:
(1)
Given
- 2x = x² - 6 ( subtract x² from both sides )
- x² - 2x = - 6 ( multiply through by - 1 )
x² + 2x = 6
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(1)x + 1 = 6 + 1
(x + 1)² = 7
(2)
Take the square root of both sides
x + 1 = ± [tex]\sqrt{7}[/tex] ( subtract 1 from both sides )
x = - 1 ± [tex]\sqrt{7}[/tex]
Solutions are x = - 1 - [tex]\sqrt{7}[/tex] , x = - 1 + [tex]\sqrt{7}[/tex]
Suppose x = 7 is a solution to the equation 4x - 2(x + a) = 8. Find the value of a that makes the equation true
Answer:
[tex]a=3[/tex]
Step-by-step explanation:
So we have the equation:
[tex]4x-2(x+a)=8[/tex]
And we want to find a such that x = 7 is a possible solution.
To do so, substitute 7 for x. Thus:
[tex]4(7)-2(7+a)=8[/tex]
Multiply the left and distribute the right:
[tex]28-14-2a=8[/tex]
Subtract:
[tex]14-2a=8[/tex]
Subtract 14 from both sides:
[tex]-2a=-6[/tex]
Divide by -2: "
[tex]a=3[/tex]
So, the value of a is 3.
And our equation would be:
[tex]4x-2(x+3)=8[/tex]
And we're done!

a = 7
