We know that the slope-intercept form of an equation is represented by:
y = mx + b
Where m is the slope, b is the y-intercept, and x and y pertain to points on the line in the graph.
So the slope of the line is know to be 3, and we are able to plug that into the equation:
y = 3x + b
We also know that the point (-2, 6) is on the line. With this information, we can then plug in the point into the equation to find b:
6 = 3(-2) + b
Then we can solve for b:
6 = -6 + b
b = 12
Knowing that b is 12, we can then rewrite the equation in a more general slope-intercept form that is applicable to any point on that line:
y = 3x + 12
Thus, your answer would be C.
B is correct
25% of 500 is 125, 500-125 is 375 which is how many remaining star stickers there are.
The answer is 74.90.
I don't understand what you mean by 'Why it doesn't show'
Answer:
A.2
Step-by-step explanation:
We know that |x|² = 13 and x = 3+bi:
(3+bi)² = 13
3² + b² = 13
9 + b² = 13
Subtract 9 from each side:
9 + b² - 9 = 13 - 9
b² = 4
Take the square root of each side:
√b² = √4
b = 2
Answer: D = 300 km
Total distance travelled is 300 km
Step-by-step explanation:
Distance = speed × time
The total distance travelled is the sum of the two distance travelled during the phases of speed.
D = v1t1 + v2t2 .....1
Given ;
speed v1 = 60km/hr ; v2 = 120km/hr
Time taken t1 = 1 hr ; t2 = 2 hr
Substituting the given values into equation 1, we have;
D = 60×1 + 120×2 = 60 + 240
D = 300 km
Total distance travelled is 300 km
