Answer:
(a.)
=(6x^2-3x)+(8x-4)
=3x(2x-1)+4(2x-1)
=(2x-1)(3x+4)
zeros are x=-4/3, x= 1/2
(b.)
=4(x^2-16)
=4(x+4)(x-4)
zeros are x= -4 and x= 4

When we have negative exponents, we can move the term with the exponent to the bottom of the fraction. This is also known as multiplying by the reciprocal (and changing the negative exponent to be positive!).
The reciprocal of z^-3 would be 1 / z^3.
Hope this helps!! :)

Find the RATIO and the EXACT VALUE of the given Cos A.
Answer:
Step-by-step explanation:
take angle A as reference angle
using cos rule
cos A=adjacent/hypotenuse
cos A=12/13
cos A=0.92
A=cos 23
A=23 degree
for ratio,
cos A=12/13
Cos( A ) = AC / AB [ Ratio ]
Cos( A ) = 12 / 13 [ Ratio ]
Cos( A ) = 0. 92307 [ Exact value ]

A line with a slope of 1 passes through the point (6,2). What is its equation in slope-intercept form? Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer:
y = x - 4
Step-by-step explanation:
Given:
Passes through (6, 2)
m = 1
Slope-intercept:
y - y1 = m(x - x1)
y - 2 = 1(x - 6)
y - 2 = x - 6
y = x - 4
The lengths of the legs of a right triangle are 8 inches and 9 inches. What is the length of the hypotenuse? Round to the nearest inch. Enter your answer in the box.
The length of the hypotenuse in a right triangle is 12 inches.
What is the Pythagoras theorem?The relationship between the three sides of a right-angled triangle is explained by the Pythagoras theorem, commonly known as the Pythagorean theorem. The Pythagoras theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.
Given that, the lengths of the legs of a right triangle are 8 inches and 9 inches.
Let the length of the hypotenuse be x.
Here, x²=8²+9²
x²=64+81
x²=145
x=√145
x=12.04
x≈12 inches
Therefore, the length of the hypotenuse is 12 inches.

What minus 9 equals 11
Answer:
20
Step-by-step explanation:
20 - 9 = 11
I hope this helps
Answer:
20
Step-by-step explanation:
Call the number you're trying to find n.
"What" becomes n.
n - 9 = 11
To "undo" the subtraction and reveal the value of n , ADD 9 to both sides of the equation. (Addition is the inverse operation of subtraction.)
n = 11 + 9 = 20
THE SUM OF A NUMBER, X
AND 9 is 21.
SOLVE FOR X.
Answer:
X + 9 = 21
Isolate the variable, meaning getting rid of the constants
-9 -9
X = 12
Answer:
12
Step-by-step explanation:
To get the answer 12 you must:
Subtract 21 - 9
That would get you your answer.
Spencer borrowed $50 from his cousin, who charged him 6% simple interest each year. If Spencer pays his cousin back 3 years later, how much will he owe his cousin?
A
$56
B
$59
С
$68
D
$6
Given:
Principal = $50
Rate of simple interest = 6%
Time = 3 years
To find:
The amount after 3 years.
Solution:
Formula for simple interest:
[tex]I=\dfrac{P\times r\times t}{100}[/tex]
Where, P is principal, r is the rate of interest in percentage and t is the number of years.
Putting [tex]P=50,\ r=6,\ t=3[/tex] in the above formula, we get
[tex]I=\dfrac{50\times 6\times 3}{100}[/tex]
[tex]I=\dfrac{900}{100}[/tex]
[tex]I=9[/tex]
Formula for amount is:
[tex]A=P+I[/tex]
Where, P is principal and I is the simple interest.
Putting [tex]P=50,\ I=9[/tex], we get
[tex]A=50+9[/tex]
[tex]A=59[/tex]
Therefore, the correct option is B.

The festival sends Dani a map of where people will launch their kites. A portion of the map is shown. How far apart does each kite flyer stand? Round to the nearest foot. Explain please hurry
Answer:
16 ft.
Step-by-step explanation:
Distance Formula:
A = (2,2)
B = (12,14)
So, sqrt(12^2 + 10^2) = 16 ft.
This is the same for B to C.
So, 16 ft.

What is the portion if the base is 450 and the rate is 19%
Answer:
portion = 85.50
Step-by-step explanation:
[tex]Rate = (\frac{Portion}{Base})*100%[/tex]
Rate = 19%, Base = 450
[tex]19 = \frac{portion}{450} \times 100\\\\19 \times 450 = portion \times 100\\\\\frac{8550}{100} = portion \\\\portion = 85.50[/tex]

- 4(2.5x - 1.25) - 3x
Answer:
-13x+5
Step-by-step explanation:
Distributive Property
-4 (2.5x) + (-4)(-1.25) - 3x
Multiply 2.5 by -4
- 10x - 4 * 1.25 - 3x
Multiply -4 by 1.25
- 10x + 5 -3x
Subtract 3x from -10x

When y is directly proportional to x, the value of y = -2 when x = 4. What is the value of y when x = 8?
Answer:
y = -4
Step-by-step explanation:
When y is directly proportional to x,
= y ∝ x
= y = kx
Finding k
the value of y = -2 when x = 4
-2 = k4
k = -2/4
k = -1/2
. What is the value of y when x = 8
Finding y
y = kx
y = -1/2 × 8
y = -4
