factor of 9x2 18x + 8?
Factor of 9x^2-18x+8
Answer:
(3x - 2)(3x - 4).
Step-by-step explanation:
9x^2-18x+8
Use the 'ac' method:
9 * 8 = 72.
We need 2 numbers whose product is + 72 and whose sum is -18
These are -12 and -6 so we rewrite the expression as:
9x^2 - 12x - 6x + 8 Now we factor by grouping:
= 3x(3x - 4) - 2(3x - 4) The 3x - 4 is common so we have:
(3x - 2)(3x - 4).
The factor of the quadratic expression 9x² - 18x + 8 will be (3x - 2) and (3x - 2).
What is factorization?It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
The quadratic expression is given below.
⇒ 9x² - 18x + 8
Factorize the quadratic expression, then the factors are given as,
⇒ 9x² - 18x + 8
⇒ 9x² - (12 + 6)x + 8
⇒ 9x² - 12x - 6x + 8
⇒ 3x(3x - 4) -2(3x - 4)
⇒ (3x - 2)(3x - 4)
Then the factor of the quadratic expression 9x² - 18x + 8 will be (3x - 2) and (3x - 2).

{(–13, 4), (7, –15), (–13, 9), (6, –12), (–18, 0)} State whether each set of ordered pairs represents a function.
Answer:
it is not a function
Step-by-step explanation:
if you can pass a vertical line through more than one point it is not a function, you have two points with the same x and different y
(-13,4) and (-13,9)
because you have two different y values for the same x it would fail the vertical line test and thus is not a function

Write the equation for the line that passes through (2, -4) and is
perpendicular to the line to x - 4y = 7.
Answer: y= x-2
Step-by-step explanation:
Perpendicularity entails the slope of line a is -1 divided by the slope of line b
m1= (-1/m2)
From y=Mx +c
We compare with x-4y=7
y=(1/4)x-7/4
Meaning m2= 1/4
m1= -1/(1/4)= -1*4= -4
((y-y1)/(x-x1))= ((y2-y1)/(x2-x1))=m1
x1= 2, y1= -4
((y-(-4))/(x-2))= -4
((y+4)/(x-2))= -4
Cross multiply
y+4= -4(x-2)
y= x-2

Rebecca ran 21 miles in 5 hours. If she ran at a constant speed, how many miles did she run in 2 hours? 8.4 miles 42 miles 4.2 miles 1.2 miles
Answer: 8.4 miles
Step-by-step explanation:
d = rt
Solve for her rate
21 = 5r
r = 21/5
r = 4.2
Solve for if the time is 2 hours and rate (solved previously) is 4.2
d = 4.2*2
d = 8.4
The distance traveled by Rebecca in 2 hours is given by d = 8.4 miles and the speed is S = 4.2 miles / hour
What is Speed?Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude
Speed = Distance / Time
Given data ,
Let the total distance ran by Rebecca be D = 21 miles
The time taken by her to travel 21 miles T = 5 hours
So , the speed of Rebecca S = D / T
On simplifying , we get
S = 21/5
S = 4.2 miles per hour
Therefore , the speed of Rebecca is 4.2 miles / hour
Now , let the time taken be T₂ = 2 hours
So , the distance traveled in 2 hours , D = ST₂
D = 4.2 x 2
D = 8.4 miles
Hence , the distance traveled is 8.4 miles

y = [ ? ] cm. Round to the
nearest tenth.
15 cm
35
90°
Answer:
y ≈ 12.3
Step-by-step explanation:
Using the SOH CAH TOA identity to get the value of y as shown;
sin theta = opposite/hypotenuse
opposite = y
hypotenuse = 15cm
theta = 180-(35+90)
theta = 180-125
theta = 55 degrees
sin 55 = y/15
y = 15sin55
y = 12.287
y ≈ 12.3 (to the nearest tenth)

See comment for complete question
Given
[tex]Amount = \$360[/tex]
[tex]Rate = \$15[/tex] weekly
Required
Determine the function to represent the scenario
The amount (L) owed in w weeks is represented as:
[tex]Amount\ Owed = Amount - Rate * Weeks[/tex]
We used negative because the amount reduces weekly.
So, we have:
[tex]L(w) = 360 - 15 * w[/tex]

180 - 153 = 27
Answer:
The inside of a triangle always equals 180 and you have angles 132 and 21. In total it's 153. Subtract 180 - 153 and you get 27.
x = 27
