Answer: correct option is B.
Step-by-step explanation:
Answer:
(2x - 5)(3x + 1)
Step-by-step explanation:
Do you mean 6x^2 - 13x - 5?
6x^2 factors into 6x, x or 3x, 2x
-5 factors into -1, 5 or -5, 1
Use combinations of the factors until you get the correct trinomial.
6x^2 - 13x - 5 = (2x - 5)(3x + 1)

A 40-degree angle is translated 5 inches along a vector. What is the angle measurement, in degrees, of the Image?
Answer:
40°
Step-by-step explanation:
As clarified in an online document, a translation along a vector (which is a line in a plane) of a figure, is equivalent to a translation along a coordinate grid, and therefore, given that a translation is a form of rigid transformation, the the dimensions and inclinations of the rays forming the preimage are the same as those in the image and the angles measurement in the preimage and the image are equal.
Therefore, given that the angle measurement of the image is 40-degrees, the angle measurement of the image is also 40-degree (40°) angle.

A point is rotated 270° about the origin. The image of the point is (-11,7). What are the coordinates of the preimage?
Choose the correct answer below.
O A. (11)
B. (7. - 11)
O C. (11,7)
OD. (-7, -11)
PLEASE HURRY
Answer:
The correct answer is C(11,7)
Step-by-step explanation:
I had this question and got it right lol
The required coordinates of the preimage are (-7, 11) when the point is rotated 270° about the origin.
What is a transformation?A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.
We have been given that a point is rotated 270° about the origin. The image of the point is (-11,7).
The coordinates of the preimage would be :
x = x cos θ + y sin θ
y = x sin θ + y cos θ
Here x = -11 ,y = 7 and θ = 270°
Substitute the values in the above equations,
x = (-11) cos 270° + 7 sin 270° = -7
y = (-11) sin 270° + 7 cos 270° = 11
Therefore, the required coordinates of the preimage are (-7, 11).

Brainliest for correct answer
Answer:
-21/5 or -4.2
Step-by-step explanation:
y = 2x + 6
3y - x + 3 = 0
Substitute the value for y from the first equation into the second equation. Solve for x.
3y - x + 3 = 0
3(2x + 6) - x + 3= 0
6x + 18 - x + 3 = 0
5x + 18 + 3 = 0
5x + 21 = 0
5x + 21 - 21 = 0 - 21
5x = -21
x = -21/5 or -4.2

Henry can type 3500 words in 70 minutes. Colin can type 1500 in 30 minutes. Brian can type 2200 words in 40 minutes. Who types at the fastest rate of words per minute?
Given:
Henry can type 3500 words in 70 minutes.
Colin can type 1500 in 30 minutes.
Brian can type 2200 words in 40 minutes.
To find:
The person who types at the fastest rate of words per minute.
Solution:
We know that,
[tex]\text{Rate of words per minute}=\dfrac{\text{Number of words}}{\text{Number of minutes}}[/tex]
Using this formula, we get
[tex]\text{Henry's rate of words per minute}=\dfrac{3500}{70}=50[/tex]
[tex]\text{Colin's rate of words per minute}=\dfrac{1500}{30}=50[/tex]
[tex]\text{Brian's rate of words per minute}=\dfrac{2200}{40}=55[/tex]
Since 55>50, therefore Brian's types at the fastest rate of words per minute.

Cameron is signing up for a gym membership with a one-time fee to join and then a monthly fee to remain a member. Let C represent the total cost of the gym membership over t months.
The graph of the function C = 100 +25m is given,
the equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.
Here,
C= 100+25t
Where C represents the total charge,
t represents the number of months as of 25 per month,
And 100 represents the one-time chargeable fee to join.
Thus, the y-intercept of the function is 100 which represents a one-time fee to join.

What survival rate in the 10th year would make the average rate of loss over the 10-year period equal to 38.0%?
Answer: 63%
Step-by-step explanation:
First find the rate of loss that would cause the average rate of loss over the 10-year period equal to 38.0%.
Assume that rate is x.
38 = (36.2 + 29.0 + 46.2 + 37.5 + 40.9 + 40.0 + 32.6 + 40.5 + 40.1 + x) / 10
38 = (343 + x ) / 10
380 = 343 + x
x = 380 - 343
x = 37%
The survival rate is the opposite of the rate of loss which means that the survival rate is;
= 1 - rate of loss
= 1 - 37%
= 63%
