Answer:
Step-by-step explanation:
We are given the line y=2x+8. It is in slope-intercept form or y= mx+b, where m is the slope and b is the y-intercept.
The slope of the line is 2.
We want to find the equation that is perpendicular. Perpendicular lines have negative reciprocal slopes.
1. Negate
- Negate the slope, or switch the sign
- (+) 2 --> -2
2. Reciprocal
- Flip the numerator and denominator of the slope.
The perpendicular slope is -1/2, so the correct equation must be B.
Isiah is 5.83 miles away from his starting point.
When you draw the the miles Isaiah walks, you will discover that you are forming a right angle triangle.
To measure the length from the starting point to the ending point. We must used the Pythagorean equation. Where in the square of the hypotenuse is equal to the sum of squares of the other two sides.
a² + b² = c²
a = 3 miles 3² + 5² = c²
b = 5 miles 9 + 25 = c²
c = hypotenuse. 34 = c²
We must get the hypotenuse, since 34 is the square of the hypotenuse we must look for its square root.
c² = 34
c = √34
c = 5.83 miles
Answer:
y = -6x + 7 has greater rate of change
Step-by-step explanation:
for the first one, the rate of change is -6x and for the second one, the rate of change is -5x so the rate of change for y = -6x + 7 is greater.
Use the formula y2 - y1 / x2 - x1 to find the slop for the second equation. the second equation is y = -5x
Answer:
The correct ans is...
3 x square + 5 x - 5
Step-by-step explanation:
U can only subtract or add if u hv the same variable..
here -2x and 7x have the same variable...
so -2x + 7x = 5x
Therefore the ans is....
3 x square + 5 x - 5
Hope this helps....
Have a GOOD DAY !!!!
Pls mark my ans as brainliest
If u mark my ans as brainliest u will get 3 extra points
Sry to say....
U really need to read ur Math TBK
Answer:
$40,000
Step-by-step explanation:
25% of x = $10,000
0.25x = 10,000
x = 10,000/0.25
x = 40,000
Answer: $40,000
