O C. x = -1, x = 14
O D. x=-14, x = 1
Answer ASAP!
Answers
Answer:
A
Step-by-step explanation:
Given
x² - 5x - 14 = 0
Consider the factors of the constant term (- 14) which sum to give the coefficient of the x- term (- 5)
The factors are - 7 and + 2, since
- 7 × 2 = - 14 and - 7 + 2 = - 5, thus
(x - 7)(x + 2) = 0
Equate each factor to zero and solve for x
x - 7 = 0 ⇒ x = 7
x + 2 = 0 ⇒ x = - 2

Write an equation of the line passing through the points (3,8) and (-2,-22)
Answers
Answer:
y=6x+8 or y=6x-22
Step-by-step explanation:
use the equation y=mx+b
m is the slope and b is the y-intercept
to find the slope use the equation m = y2-y1 over x2-x1
-22 - 8 / -2 - 3 = -30 / -5 = 6
6 is your slope and for the y-intercept you can choose whichever y-intercept to put into the equation.

Step-by-step explanation:
At her birthday party, Ms. Willow would not give her age directly. She said, 'If you add the year of my birth to this year, subtract the year of my 25th birthday and the year of my 55th birthday, and then add my present age, the result is 58.
Answers
Answer:
69 years
Step-by-step explanation:
Given that:
Let year of birth = x
This year = 2020
Year of 25th birthday = x + 25
Year of 55th birthday = x + 55
Present age = 2020 - x
Hence,
x + 2020 - (x + 25 + x + 55) + (2020 - x) = 58
x + 2020 - (2x + 80) + (2020 - x) = 58
x + 2020 - 2x - 80 + 2020 - x = 58
-2x + 4040 - 80 = 58
-2x + 3960 = 58
-2x = 58 - 3960
-2x = - 3902
x = 1951
Birth year = 1951
,
Hence, age =
2020 - 1951 = 69 years

Step-by-step explanation:
gradient = -2
x = 6, y = 8
y - 8 = -2(x - 6)

Step-by-step explanation:
zeros are the x-intercepts of any function. to find the x-intercept of this given function, we have to set y equal to 0.
0= -1/2x+6
-6=-1/2x
12=x
x=12
the x-intercept is (12,0), meaning 12 is the zero of this function.
A scale drawing of a school bus has a scale of 12 inch to 5 feet. If the length of the school bus is 412 inches on the scale drawing, what is the actual length of the bus? Explain or show your reasoning. A scale drawing of a lake has a scale of 1 cm to 80 m. If the actual width of the lake is 1,000 m, what is the width of the lake on the scale drawing? Explain or show your reasoning.
Answers
Answer: Actual length of the bus = 171.67 feet
Width of the lake on the scale drawing = 12.5 inches
Step-by-step explanation:
Given : A scale drawing of a school bus has a scale of 12 inch to 5 feet.
i.e. 12 inch = 5 feet
[tex]\Rightarrow \text{ 1 inch}=\dfrac{5}{12}\text{ feet}[/tex]
If length of school bus on scale drawing = 412 inches
Then, Actual length of bus = [tex]\dfrac{5}{12}\times412=171.67\ \text{feet}[/tex]
A scale drawing of a lake has a scale of 1 cm to 80 m.
If the actual width of the lake is 1,000 m
then, the width of the lake on the scale drawing = [tex]\dfrac{1000}{80}=12.5\text{ inches}[/tex]
Are these lines parallel,
perpendicular, or neither?
Line 1 passes through (0,3) and (3,1)
Line 2 passes through (-1,4) and (-7,-5)
Answers
First, find the slope of each line by using the point slope formula [(y2-y1)/(x2-x1)]. You should get that the slope line 1 is -2/3 and the slope of line 2 is 3/2. Using this, we can conclude that both the lines are perpendicular because their slopes are opposite reciprocals (meaning you flip one fraction and change its sign to get the other fraction).

For a data set of weights? (pounds) and highway fuel consumption amounts? (mpg) of eight types of? automobile, the linear correlation coefficient is found and the? P-value is 0.001. Write a statement that interprets the? P-value and includes a conclusion about linear correlation.The? P-value indicates that the probability of a linear correlation coefficient that is at least as extreme is nothing?%, which is ? low, high, so there ? is not is sufficient evidence to conclude that there is a linear correlation between weight and highway fuel consumption in automobiles
Answers
Answer:
The correct option is;
Low
Step-by-step explanation:
Given that the P-value of the linear correlation = 0.001, we have that the P-value is a demonstration that a linear correlation that has a value in the range of the given correlation is ,most arguably very low
From the z-table, a P-value of 0.001 corresponds to a z-value of -3.09, we have that in a normal distribution since 95% of the scores have a z-score of between -2 and 2, the z-score of -3.09 is very distant from the mean and having a low value, whereby the P-value shows that the likelihood of finding another linear correlation that is as far from the mean as the given correlation is very low.
