please help me Herbert and Samantha are both driving from Orlando to Miami. Herbert
leaves at 9:00 and averages 60 mph (miles per hour) on the way. Samantha
leaves at 9:10 and averages 65 mph on the way. The situation is modeled by
this system, where x is the number of hours after Samantha leaves and y is
the distance each will travel:
y = 60x + 10
y = 65x
How long after Samantha leaves will she pass Herbert, and how far will they
each have traveled?
A. Samantha will not pass Herbert, because she will never catch up
with him
B. Samantha will pass Herbert after 3 hours, and they each will have
traveled 180 miles.
O C. Samantha will pass Herbert after 2 hours, and they each will have
traveled 130 miles.
O D. Samantha will pass Herbert after 3 hours, and they each will have
traveled 190 miles.
Answer:
B 2 hours of 130 miles is the 60th term of the y intercept!

2/3y - 2/5 = 5, what is the value of y? *
Answer:
y=3.6 or 18/5 or you can turn it into any other fraction
Step-by-step explanation:
2/3y - 2/5 = 5
+2/5 +2/5
2/3y = 27/5
multiply by 2/3 on both sides
y=3.6 or 18/5 or you can turn it into any other fraction

If sin theta + cos theta=mand sec theta+ cosec theta =n then n(m+1)(m-1)=?
sin A + cos A = m -- equation (1)
sec A + Cosec A = n -- equation (2).
Find:value of n(m+1)(m-1)
Solution:We have to find:
n(m + 1)(m - 1)
using (a + b)(a - b) = a² - b² we get,
⟹ n (m² - 1²)
⟹ m²n - n
Putting the values from equations (1) & (2) we get,
⟹ (sin A + cos A)² * (sec A + Cosec A) -
(sec A + Cosec A)
(a + b)² = a² + b² + 2ab
⟹ (sin² A + cos² A + 2sin A Cos A ) * (sec A + Cosec A) - sec A - Cosec A
using the identity sin² A + cos² A = 1 we get,
⟹ ( 1 + 2 sin A cos A ) * (sec A + Cosec A) - sec A - Cosec A
⟹ 1(sec A + Cosec A) + 2sin A cos A(sec A + Cosec A) - sec A - Cosec A
⟹ sec A + Cosec A + 2 sin A * cos A * sec A + 2 sin A cos A Cosec A - sec A - Cosec A
using sin A * Cosec A = 1 & cos A * sec A = 1 we get,
( sec A + Cosec A & - sec A - Cosec A are being cancelled )
⟹ 2 sin A + 2 cos A
⟹ 2 (sin A + cos A)
Putting the value sin A + cos A from equation (1) we get,
⟹ 2m
∴ n (m + 1)(m - 1) = 2m.

What would the equation of y = x + 3 be if it is translated seven units up?
Answer:
y=x+10 would be the answer
Answer:
y = x + 10
Step-by-step explanation:
A graph translated 7 units up is just x + 7. However, we already have an equation, so we need to add 7 to 3 first.
y = x + (3 + 7)
y = x + 10

a.) y - 11 = (x+3)
Slope of line
Answer:
m = 1
Step-by-step explanation:
y - 11 = (x+3) can be compared to the gneral point-slope formula
y - k = m(x - h), where (h, k) is a point on the line.
Notice that the coefficient of (x + 3) is 1; therefore we know immediately that the slope of the line is m = 1.

A linear function is shown on the graph and in the table.
What are the slope and y-intercept of the linear function?
A) The slope is - 1/3 and the y-intercept is 147.
B) The slope is 3 and the y-intercept is 147.
C) The slope is –3 and the y-intercept is 150.
D) The slope is 1/3 and the y-intercept is 150.
Answer:
slope is -3, y-intercept is 150 [C]
Step-by-step explanation:
The slope is –3 and the y-intercept is 150. Therefore, option C is the correct answer.
What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The formula to find the slope of a line is slope = (y₂-y₁)/(x₂-x₁).
From the table we have (1, 147) and (3, 141).
Here, slope (m) = (141-147)/(3-1)
= -6/2
= -3
Substitute m=-3 and (x, y)=(1, 147) in y=mx+c, we get
147=-3(1)+c
c=147+3
y-intercept =c=150
Therefore, option C is the correct answer.

L.B. Johnson Middle School held a track and field event during the school year. Miguel took part in a four-person shot put team. Shot put is a track and field event where athletes throw (or “put”) a heavy sphere, called a “shot,” as far as possible. To determine a team score, the distances of all team members are added. The team with the greatest score wins first place. The current winning team’s final score at the shot put is 52.08 ft. Miguel’s teammates threw the shot put the following distances: 12.26 ft., 12.82 ft., and 13.75 ft. Exactly how many feet will Miguel need to throw the shot put in order to tie the current first-place score? Show your work.
Answer:
11.25 ft
Step-by-step explanation:
To determine a team score, the distances of all team members are added.
The current winning team’s final score at the shot put is 52.08 ft.
So, in order to tie the score Miguel's team must equal the above score.
The total score before Miguel's throw was 12.26+12.82+13.75= 38.83 ft
so , Miguel will have throw 52.08-38.83= 11.25 ft in order to tie the score.

I need to find the answer for d
[tex]\tt Step-by-step~explanation:[/tex]
To solve for d, we have to move all the terms that do not equal to d to one side of the equation and leave d on the other side.
[tex]\tt Step~1:[/tex]
First, subtract n from both sides.
[tex]\tt 9d+n-n=57-n\\9d=57-n[/tex]
[tex]\tt Step~2:[/tex]
Divide all terms by 9 to get the variable d by itself.
[tex]\tt \frac{9d}{9} =d\\\\\frac{-n}{9} =-\frac{n}{9}\\\\\frac{57}{9}=6\frac{1}{3} ~or~\frac{19}{3} \\\\d=-\frac{n}{9} +\frac{19}{3}[/tex]
[tex]\Large\boxed{\tt Our~final~answer:~d=-\frac{n}{9} +\frac{19}{3} }[/tex]
[tex] \LARGE{ \underline{ \pink{ \bf{Required \: answer:}}}}[/tex]
Since there are two variables in the equation and no other simultaneous equation is not given, We need to express d in terms of other elements in the equation.
GiveN:
9d + n = 57So, Let's find d from the above equation. Subtracting n from both sides of the equation.
⇛ 9d = 57 - n
Now dividing the equation by 9,
⇛ 9d / 9 = 57 - n / 9
⇛ d = 57 - n / 9
Thus, the required answer for d is:
[tex] \boxed{ \rm{d = \frac{57 - n}{9} }}[/tex]
And we are done ......

Point B(-8,5) is dilated from the origin by scale factor r=1/2 what are the coordinates of point B?
Answer:
The coordinates of point B are (-4,5/2)
Step-by-step explanation:
The transformation B(-8,5) →(-8/2, 5/2) represents a dilation centered at the origin.
What is a transformation?When a point is relocated from its original place to a new location, it is changed. Different transformations include translation, rotation, reflection, and dilation.
You can dilate figures on the coordinate plane. The origin is commonly used as the dilatation center. You can identify the points in the picture if you deform a figure centered at the origin by multiplying the coordinates of the points in the preimage by the scale factor.
We have been given that Point B(-8,5) is dilated from the origin by scale factor r = 1/2
The scale factor i.e. 0.75 is multiplying the coordinates of the points B(-8,5)
So the coordinates of point B = (-8/2, 5/2)
Thus, the transformation B(-8,5) →(-8/2, 5/2) represents a dilation centered at the origin.

One angle of a triangle measured 70 the other two angles are in a ratio of 7 : 15 what are the measures of those two angles
Answer:
35°, 75°
Step-by-step explanation:
Let the measures of the remaining two angles be 7x and 15x
By interior angle sum Postulate of a triangle.
70° + 7x + 15x = 180°
22x = 180° - 70°

x = 5°
7x = 7*5° = 35°
15x = 15*5° = 75°
Suppose that diastolic blood pressure readings of adult males have a bell-shaped distribution with a mean of 82 mmHg and a standard deviation of 12 mmHg. Using the empirical rule, what percentage of adult males have diastolic blood pressure readings that are no more than 94 mmHg?
Answer:
68%
Step-by-step explanation:
Suppose that diastolic blood pressure readings of adult males have a bell-shaped distribution with a mean of 82 mmHg and a standard deviation of 12 mmHg. Using the empirical rule, what percentage of adult males have diastolic blood pressure readings that are no more than 94 mmHg?
Empirical rule states that:
68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ.
95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ.
99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ.
We are given:
mean of 82 mmHg and a standard deviation of 12 mmHg.
68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ.
μ - σ
