Find the equation of the line through the points (-8,3) and (-4,5).
Answer:
[tex]2y - x = 14[/tex]
Step-by-step explanation:
Given
[tex](x_1,y_1) = (-8,3)[/tex]
[tex](x_2,y_2) = (-4,5)[/tex]
Required
The line equation
First, calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{5 - 3}{-4 - (-8)}[/tex]
[tex]m = \frac{2}{4}[/tex]
[tex]m = \frac{1}{2}[/tex]
The equation is then calculated as:
[tex]y = m(x - x_1) + y_1[/tex]
[tex]y = \frac{1}{2}(x - (-8)) +3[/tex]
[tex]y = \frac{1}{2}(x +8) +3[/tex]
Open bracket
[tex]y = \frac{1}{2}x +4 +3[/tex]
[tex]y = \frac{1}{2}x +7[/tex]
Multiply through by 2
[tex]2y = x + 14[/tex]
[tex]2y - x = 14[/tex]

Answer:
x = 23
Step-by-step explanation:
the sum of all interior angles of triangle is 180 dehrees.
top angle = 180-100 = 80 degrees
80 + 51 + (2x+3) = 180
2x+3 = 49
2x = 46
x = 23

John sells apples for $5 per bunch and watermelons for $3 a piece. He made $100 today and sold 10 watermelons. How many bunches of apples did he sell?
Answer:
14
Step-by-step explanation:
3*10=30
5*14=70
30+70=100!!!
Answer:
he sold 14 apples
Step-by-step explanation:
multiply 10 (watermelon) and 3 (the cost) which is 30
now subtract 30 from 100 which is 70
last do 5 (the cost of apple bunch) by 70 to find the total number of bunches he sold which is 14
Find the Median for the following set of numbers.
6, 9, 8, 11, 17, 17, 16
2t + 4(4 + 10t)
Simplify the expression
Answer:
=42t+16
Step-by-step explanation:
=2t+(4)(4)+(4)(10t)
=2t+16+40t
=2t+16+40t
=(2t+40t)+(16)
=42t+16
Simplify the expression
2t + 4(4 + 10t)
Simplifying
y = 2t4 + -10t2 + 13
Reorder the terms:
y = 13 + -10t2 + 2t4
Solving
Solving for variy = 13 + -10t2 + 2t4
able 'y'.
Move all terms containing y to the left, all other terms to the right.
Simplifying
y = 13 + -10t2 + 2t4
Hence the information I've given you, we can now state that the answer is
42 t + 16
Find the volume of a pyramid with a square base, where the perimeter of the base is 7.4 ft and the height of the pyramid is 8.1 ft. Round your answer to the nearest tenth of a cubic foot.
9514 1404 393
Answer:
9.2 ft³
Step-by-step explanation:
The side length of the square base is 1/4 of the perimeter, so is ...
s = P/4 = (7.4 ft)/4 = 1.85 ft
The area of the base is the square of this, or ...
A = s² = (1.85 ft)² = 3.4225 ft²
The volume of the pyramid is given by ...
V = 1/3Bh = (1/3)(3.4225 ft²)(8.1 ft) = 9.24075 ft²
The volume of the pyramid is about 9.2 cubic feet.
Every morning, Jim goes for a morning walk. His normal walking speed is 3 1/2 km per hour, and he walks a total distance of 10 km every day. How much time does he take to cover one km?
Hint 1 Notice the unit of Speed.
Hint 2 Can you figure out the distance covered in one hour
Answer:
Jim's walking speed = 312kmph
covered distance = 10km
time taken for one hour = ?
we know that: Distance =speed × time
=>Time = Distance/speed
=> Time = 10/312=5/156 hours
= Time = (5×60)/156=300/156=75/39=1.9 minutes
Step-by-step explanation:
The temperature changes from 9°F to -5°F. Which of the following expressions model the distance on thermometer between 9°F and -5°F? Choose all the correct answers
A I -5 -9 I
B I 9 -5 I
C I 9- (-5) I
D I -5 (-9) I
E I -9 - (-5) I
Answer:
[tex]d = |- 5- 9|[/tex]
Step-by-step explanation:
Given
[tex]Initial = 9^\circ F[/tex]
[tex]Final = -5^\circ F[/tex]
Required
Determine the difference
Represent this with d.
d is calculated using
[tex]d = |Final - Initial|[/tex]
The equation becomes
[tex]d = |- 5- 9|[/tex]
