Find the value of k such that the line through (k+3,7) and (-5,3 – k) has a
slope of 5/3.
Answers
Answer:
k= -14
Step-by-step explanation:
[tex]\boxed{slope = \frac{y1 - y2}{x1 - x2} }[/tex]
[tex] \frac{5}{3} = \frac{7 - (3 - k)}{k + 3 - ( - 5)} [/tex]
[tex] \frac{5}{3} = \frac{7 - 3 + k}{k + 3 + 5} [/tex]
[tex] \frac{5}{3} = \frac{4 + k}{k + 8} [/tex]
Cross multiply:
3(4 +k)= 5(k +8)
Expand:
12 +3k= 5k +40
Bring k terms to one side, constant to the other:
5k -3k= 12 -40
Simplify:
2k= -28
Divide both sides by 2:

Jeremy has $1200 in spending money for the fall semester of college. He needs to purchase car insurance at $120 for 4 months, $25 a week to buy his lunch in the cafeteria every day, and $20 bi weekly for entertainment. If the semester is 16 weeks long, will Jeremy have $200 to spend on Christmas presents for his family? Explain
Answers
Answer:
Jeremy Will have more than just $200 to spend on Christmas presents.
Explanation :
He has a total of $1200.
He spends a $120 for car insurance. (1)
He needs to spend $25 a week for lunch. He has to do this for 16 weeks so 25*16 = $400. (2)
He needs to spend $20 a week for entertainment. For 16 weeks that'll be 20*16 = $320 (3)
adding (1) (2) and (3)
We get Jeremy's total spending will be $840. Jeremy has $1200.
1200-840 = $360
So Jeremy will have $360 to spend on Christmas present.

Gabriel borrowed some money from his friend in order to help buy a new video game system. Gabriel agreed to pay the friend back some amount every week until his loan was paid off. Let LL represent the amount Gabriel owes his friend after tt weeks. A graph of LL is shown below. Write an equation for LL then state the slope of the graph and determine its interpretation in the context of the problem.
Answers
The equation of the line is y = (15/2)x + 80.
The slope of the line is 15/2.
We have,
The coordinates from the graph:
(0, 80) (2, 65) and (3, 55).
Now,
The slope can be calculated as:
= (d - b) / (c - a)
where (a, b) and (c, d) are the two coordinates.
Consider (a, b) = (0, 80) and (c, d) = (2, 65)
Slope = (65 - 80) / (2 - 0)
Slope = 15/2
Now,
The equation of the line:
y = mx + c _______(1)
Where m is the slope and c is the y-intercept.
Consider: (0, 80) = (x, y)
80 = 15/2 x 0 + c
c = 80
And,
Substitute c = 80 and m = 15/2 in (1).
y = (15/2)x + 80
Thus,
The equation of the line is y = (15/2)x + 80.
The slope of the line is 15/2.

Answers
Answer:
CM = 16
MD = 16
CD = 32
Step-by-step explanation:
To find the value of x
3x + 1 = 8x - 24 (we know that M is the mid point so both of the lines will be equal)
Transpose
1 + 24 = 8x - 3x
25 = 5x
x = 25/5
x = 5
CM = 3x + 1
= 3(5) + 1
= 15 +1
= 16
MD = 8x - 24
= 8(5) - 24
= 40 - 24
= 16
CD = CM + MD
= 16 + 16
= 32

• Negatives are on the LEFT side of the number line
• Positives are on the RIGHT side of the number line.
• Negatives are BELOW 0 (less than 0)
• Positives are ABOVE 0 (more than 0)
• You have to take the value of the LARGER number.
• If your LARGER number is a negative number then your result will be a negative.
• If your LARGER is a positive number then your result will be a positive
• Negative & Negative = Positive
• Negative & Positive = Negative
• Positive & Positive = Positive
• Positive & Negative = Negative
y = -50 + 31
• So, you start from -50 and go UP 31 spaces to the right because “31” is a positive number.. once when you have moved UP your 31 spaces you have reached your answer for this given equation
y = -50 + 31
y = -19
Therefore, your answer is: y = -19

Answers
Answer:
12 or 15Step-by-step explanation:
Let the first term is a and common difference is d.
Given:
a, a₅ and a₁₀ form a GP ⇒ a₅/a = a₁₀/a₅a₂ + a₈ = 30a = ?Use the equation of nth term:
a₅ = a + 4da₁₀ = a + 9da₂ = a + da₈ = a + 7dAccording to the given we have:
(a + 4d)² = a(a + 9d) a² + 8ad + 16d² = a² + 9ad16d² = add(16d - a) = 01. d = 0or
2. a = 16dNow, use the equation of sum:
a + d + a + 7d = 302a + 8d = 30a + 4d = 15a = 15 - 4dCompare the value of a and find d:
1. d = 0
a = 15 - 4*0 = 15, in this case all the terms are same2. a = 16d
15 - 4d = 16d20d = 15d = 15/20d = 0.75Find a:

Use the formula to find the height of a traingle with a base length of 8 inches and an area of 39 square inches.
Answers
Answer:
h=39/4
Step-by-step explanation:
area of a triangle = 1/2(b*h)
base = 8 inches
area =39 square inches
input the values given:
39=1/2(8*h)
multiply the right side by 1/2
39=(1/2)8h
find half of 8
39=1/2*8 (h)
hence,
39=4h
divide both sides by 4
hence,

Now show why there are other possibilities wrong
Option A increases with the altitude, which violets the particular condition.Option C again increases at this temperature as the altitude increases and abruptly falls to 20, which is not our condition.option D up to 51.8 sounds excellent, however, this is achievable as is our given situation but the temperature goes to 59.3, therefore, this option is also refused.Learn more:
