What is the slope of a line that passes through the points (12,7) and (-14,19)?
F) -13/6
G) -1
H) -6/13
J) 3
Answer:
H) -6/13
Step-by-step explanation:
To find the slope of the line between a pair of two points, use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]. Substitute the x and y values of (12,7) and (-14,19) into the formula and simplify like so:
[tex]m = \frac{(19)-(7)}{(-14)-(12)} \\m =\frac{19-7}{-14-12} \\m = \frac{12}{-26} \\m = -\frac{6}{13}[/tex]
So, Option H is correct.

Answer:
A.) Step 1
Step-by-step explanation:
The actual answer is g=4.
Trevor screwed up at Step 1.
His answer (g = 4/9) to Step 1 (g/3 ⋅ 3 = 4/3 ⋅ 1/3 ) is correct, but it's not the correct answer for g/3 = 4/3.
In Step 1, Trevor's equation was accurate, until the last number (1/3).
If he had flipped 1/3 to 3/1, he would've been correct.
g/3 ⋅ 3 = 4/3 ⋅ 1/3 ← MISTAKE.

There are 40 students in a class. Boys makeup 40% of the class. If 25% of the boys wearshirt jacs, how many boys wear shirt jacs?
Answer:
6
Step-by-step explanation:
Find out how many boys makeup the class.
100% = 40
1% = 40 ÷ 100 = 0.40
40% = 0.40 x 40 = 16
Find 25% of the class.
25% = 0.40 x 25 = 10
40 - 25 = 15% of the boys wear shirt jacs.
16 - 10 = 6

During the day, Lola's dog is tied by rope to a tree in the center of her yard. The scale drawing below shows the area that the dog has to run, in inches. If the actual length of the rope is 11 2/3 feet, what is the scale used in the drawing?
Answer:
5 /448
Step-by-step explanation:
Radius in drawing = 1 9/16 in
The actual length of rope = 11 2/3 feets
Converting actual length to inches :
1 feet = 12 inches
11 2/3 feets = (11 2/3) * 12 = 140 inches
To obtain the scale used, we divide the Radius in the drawing by the actual length :
1 9/16 ÷ 140
25 /16 ÷ 140
25 /16 * 1 /140
= 25 / 2240
= 5 /448
Hence, scale is 5 /448 times the actual length of drawing
Hence :
The scale used is :
1 feet = 7.4666 inches
Answer:
5/488

Answer:
El primer número es 10.
z = 45.
La edad de Jaime es de 3 años.
Step-by-step explanation:
Estos problemas los podemos resolver planteando las ecuaciones:
El triple del número (3X) + 9 veces el mismo número (9X) = 120
3X + 9X = 120
12X = 120
X = 120 / 12
X = 10

Alex drives at an average speed that is 2/5 of the average speed that Roy's train travels. Alex takes 30 minutes to travel 50 km in her car. Roy travels for 1 hour and 20 minutes on his train. How far does Roy travel to 2 dp (decimal places)?
Answer: 333.33km
Step-by-step explanation:
Average speed is calculated as:
= Distance / Time
Since Alex takes 30 minutes to travel 50 km in her car, Alex average speed will be:
= 50km / 30minutes
= 50km / 0.5hour
= 100km/hour
Since Alex drives at an average speed that is 2/5 of the average speed that Roy's train travels. Roy's average speed will be:
= 100 ÷ 2/5
= 100 × 5/2
= 250km/hour
Since Roy travels for 1 hour and 20 minutes on his train, his distance travelled will be:
= Speed × Time
= 250 × 1 hour 20 minutes
= 250 × 1 20/60
= 250 × 1 1/3
= 250 × 4/3
= 1000/3
= 333.33km
Roy travels 333.33km

4. An oil palm plantation uses fertiliser at a rate of 350 kg per hectare. State the rate of
fertiliser consumption in g per m². [1 hectare = 10 000 m²]
Answer:
35
Step-by-step explanation:
1kg= 1000g
1 hectare = 10 000 m²
1 kg/hct = 1000/10 000 g/m²
1 kg/hct = 1 / 10 g/m²
350 kg per hectare is equal to 350 / 10 = 35 g/m²
1,find the equation of the line with y-intercept (0,8) and slope ⅗. 2,Find the slope and y-intercept of y=10x-⅓. 3,Find the slopes of the lines containing these points. a) (4,-3) and (6,-4) b)
Answer:
1) y = 3/5x + 8
2) Slope: 10
y-intercept: -1/3
3) y = -1/2x - 1
Step-by-step explanation:
1) The equation you need to refer to for this problem is y = mx+b
m = slope (3/5 for this problem)
b = y-intercept(which is 8)
plug those numbers in and you get y = 3/5x + 8
2) look back at this equation: y = mx+b
10 is the slope and -1/3 is the y-intercept
3) This one is a bit more difficult as you need two other formulas to solve:
the slope formula, y1 - y2/x1 - x2, and the point-slope formula,
y - y1 = m(x - x1)
For this problem, you have the coordinates (4, -3) and (6, -4) which you would plug into the slope formula, like this:
-3 -(-4)/4 - 6 = -1/2
the numbers 1 and 2 in this formula refer to the first (x,y) value and the second. You subtract the two y values and the two x values, simplify, and you get your answer.
-1/2 is going to be the m, or slope, that you will use in the second formula, the point slope formula, y - y1 = m(x - x1)
To solve this you choose one of the original coordinates that you were given to plug into the y1 and x1, and plug -1/2, your slope, in for m:
(keep in mind, for this, I used (4,-3) but you can use either one)
y -(-3) = -1/2(x - 4)
To solve this you, first, distribute -1/2 to x and -4 inside the parentheses:
y -(-3) = -1/2x + 2
Then, on the other side, add the to negatives to get a positive 3:
y + 3 = -1/2x + 2
and subtract 3 from both sides:
y = -1/2x - 1
I hope this isn't too confusing
good luck!
If the car spends no time going 35 miles per hour how long would the trip take?
Answer:
can you specify how fast the car is going? if the car goes 35 miles per hour and the trip is 3 hours its 105 miles in total for your trip. I hope this helps.
The total time that the car will take to cover the trip would be {x}/35 hours.
What is distance?Distance in kinematics is defined as the product of speed and time.
Mathematically, we can write distance covered as -
distance = speed x time
Given to find the time duration of trip if the car is travelling at 35 miles per hour.
Assume that the total distance that has to be travelled by the car is {x}
miles. From the formula of distance covered, we can write that -
distance = speed x time
time = distance/speed
time = x/35
Therefore, the total time that the car will take to cover the trip would be {x}/35 hours.

On a field trip to the farm, students counted a combined total of 27 sheep
and cows. There are 15 more sheep than cows. If s represents the number
of sheep and c represents the number of cows, which system of equations
correctly represents this situation
Answer:
s = c + 15
s + c = 27
substitute for s:
(c + 15) + c = 27
2c = 12
c = 6
s = 21
The system of equation which correctly represents the situation is s + c = 27 and s - c = 15.
What does a System of Linear Equations define?Linear equations involve one or more expressions including variables and constants and the highest exponent of the variable is 1.
System of linear equations involve two or more linear equations.
Given that,
Combined total of sheep and cows = 27
Number of sheep = Number of cows + 15
Let s represents the number of sheep and c represents the number of cows.
s + c = 27
s = c + 15 ⇒ s - c = 15
Hence the system of equation is s + c = 27 and s - c = 15.
