7z2−38z+15 Select the factors of this quadratic expression.
Answer:
(7z-3)(z-5)
Step-by-step explanation:
7z^2-38z+15
(7z-3)(z-5)
Answer:
(z - 5)(7z - 3)
Step-by-step explanation:
Given
7z² - 38z + 15
Consider the product of the factors of the coefficient of the z² term and the constant term which sum to give the coefficient of the z- term
product = 7 × 15 = 105 and sum = - 38
The factors are - 35 and - 3
Use these factors to split the z- term
7z² - 35z - 3z + 15 ( factor the first/second and third/fourth terms )
= 7z(z - 5) - 3(z - 5) ← factor out (z - 5) from each term
= (z - 5)(7z - 3) ← in factored form

Subtract. Express your answer in lowest terms. 10 5/11 - 4 2/11
Answer:
6 3/11
Step-by-step explanation:
Subtract the whole numbers: 10 - 4 = 6
Subtract the fractions: 5/11 - 2/11 = 3/11
10 5/11 - 4 2/11 = 6 3/11

Owen is planning surgery to repair the torn ligament in his knee. The total cost of the surgery is expected to be about $7,000. Owen has a $1,000 deductible and then a 20 per- cent co-pay for this procedure. How much will Owen pay for his part of the surgery?
Answer:
$2200
Step-by-step explanation:
Given that Owen has $7000 to pay, with a $1000 deductible. This means that he has, left to pay, $6000.
Again, we're told that he has 20% Co pay for the procedure. Taking 20% of $6000, we have
20/100 * 6000 = $1200. This means be has $1200 to co pay for the procedure.
Adding this newly calculated $1200 with the previously set aside $1000, we have a total of $2200. This is the price Owen will pay from his part, as part of the surgery

Write a function to represent each series of transformations:
• rotation of 90 degrees counterclockwise about the origin, point O, then a reflection across the x-axis
• reflection across the y-axis, then a translation a units to the right and b units up
• translation a units to the right and b units up, then a rotation of 180 degrees counterclockwise about the origin, then a reflection across the y-axis
Answer:
Step-by-step explanation:
For the first one, I believe you would need to use a rotation matrix; to rotate 90º counterclockwise, the matrices would look like ; you would then multiply those out. A reflection across the x-axis would be changing the sign of f(x) (from negative to positive or positive to negative), a reflection across the y-axis would be changing the sign of x, translation a units to the right would be subtracting a from x, translation b units up would be adding b to x. Rotation of 180º about the origin would be the same format as the first matrix, except it would be cos180 and cos0 on the top and sin180 sin0 on the bottom. Reflection across the y-axis would be changing the sign of x again.
OR
1. We know that, 'Translation shifts the figure in any direction'.
As, the function f(x) is translated 'a' units to the right, the new form of function is f(x-a).
Again, the function is translated 'b' units up, the final form of the function is f(x-a)+b.
2 and 3. We know that, ' Reflection flips the image over a line'.
As the function g(x) is reflected over y-axis, the new form of the function is g(-x).
As the function h(x) is reflected over x-axis, the new form of the function is -h(x).
4 , 5 and 6. We know that, 'Rotation turns the image around a point to a certain degree'.
Let us assume the function to be a point (x,y).
As the function is rotated by 90° counterclockwise about the origin, the new function becomes ( y,-x ) i.e. R_{90}R
90
(x,y) = ( -y,x ).
As the function is rotated by 180° counterclockwise about the origin, the new function becomes ( y,-x ) i.e. R_{180}R
180
(x,y) = ( -x,-y ).
As the function is rotated by 2700° counterclockwise about the origin, the new function becomes ( y,-x ) i.e. R_{270}R
270

PLEASE HURRY!! What is the location of point A?
Answer:
(-2,1) or Option 4
Step-by-step explanation:
So the way I did it is you look at the row x first then y. So when looking at row x you see that point A is located at -2. Then when you are looking at column y you see that point A is at 1.
So (-2,1) is your answer.

Energy and mass are related by the formula
E = mc².
m is the mass of the object
c is the speed of light
Solve the equation for the mass of the object, m.
Answer:
m=E/c².
Step-by-step explanation:
Transposing the formula
E=mc²
we divide both sides by c² then cancel out where necessary so m would stand alone
E/c²=mc²/c²
cancelling c² on the right hand side, equation becomes
m= E/c²

What is the slope of the line
Answer:
B) 4
Step-by-step explanation:
Use the slope formula:
slope [tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Let:
[tex](x_1 , y_1) = (1 , -2)\\(x_2 , y_2) = (2 , 2)\\[/tex]
Plug in the corresponding numbers to the corresponding variables:
slope:
[tex]m = \frac{2 - (-2)}{2 - 1} \\m = \frac{2 + 2}{2 - 1}\\m = \frac{4}{1} = 4[/tex]

tara has two bags of marbles. the first bag contains 6 red marbles, 5 blue marbles and 4 green marbles. the second bag contains 3 red marbles, 2 blue marbles, and 4 green marbles. tara will randomly select 1 marble from each bag. what is the probability that tara will select a blue marble from each bag.
Answer:
From the first bag the probability is 5 out of 15 or 1/3 simplified
The second bags probability is 4 out of 9
All the bags combined the probability is 9 out of 24
Step-by-step explanation:
The probability should be set up by putting the blue marbles as the numerator and the sum of all the marbles combined for the denominator
