D. 8°
Explanation: A triangle is always 180° and we know of two points is 50° and 80°, the other must be 60, the 60° is cut in half so if it’s 30° the other side must be thirty. DBC Is 30+50
Answer:
For 30 mph it’s 44 feet.
For 60 mph it’s 88 feet.
Step-by-step explanation:
For the 30 mph, you have to divide 30 by 60 (minutes), then you divide it by 60 (seconds). After that, you multiply by 5280 and then you’ll get 44 feet.
For the 60 mph, you have to divide 60 by 60 (minutes), then you divide it by 60 (seconds). After that, you multiply by 5280 and then you’ll get 88 feet.
Answer:
x = -1
Step-by-step explanation:
Given
2x + 2 = 4x + 4 ( subtract 4x from both sides )
- 2x + 2 = 4 ( subtract 2 from both sides )
- 2x = 2 ( divide both sides by - 2 )
x = - 1
Answer:
53 Meters.
Step-by-step explanation:
34*34 + 41*41 = 2837.
1156 + 1681 = 2837.
The square root of 2837 would be your answer.
34*34 + 41*41 = 53.26349 * 53.26349
a*a + b*b = c*c.
a² + b² = c².
Subtract 2x from both sides.
3y = - 2x - 12
Divide every term by 3 to get the y-variable by itself.
y = - 2/3x - 4
Since the equation is not in slope-intercept form (y = mx + b), your y-intercept is just the number in the b slot. Y-intercept is - 4 or (0, - 4).
Now to find your x-intercept, plug in 0 where the y-variable is and solve for x.
0 = - 2/3x - 4
4 = - 2/3x
Multiply both sides by - 3/2 to isolate the variable.
4(- 3/2) = x
- 12/2 = x
- 6 = x.
Your x-intercept is - 6 or (- 6, 0).
