Hello:
the equation of "m" is : y = ax+b
the slope is a : a×(- 2/3) = -1......( perpendicular to a line : y=-2/3x+6 when the slope is -2/3 )
a = 3/2
the line " n" that passes through (4, - 3) and parallel to line "m" :
when the slope is 3/2 ( same slope )
the equation in slope-intercept form of the line" n" is :
y – (-3)= (3/2)(x – 4)
Answer:
5 tripled is 15, x=5
Step-by-step explanation:
14-9=5 which is the number you're looking for, and 3×5=15
△ABC right angle C, leg BC > leg AC. So angle A > angle B.
a=BC, b=AC, c=AB
a > b
sin A= cos B = a/c
sin B = cos A = b/c
a = c sin A = c cos B
b = c sin B = c cos A
a > b
c sin A > c sin B
sin A > sin B
c cos B > c cos A
cos B > cos A
Answer: B, E
Answer:
a).
= (67×10)÷2
= 670 ÷ 2
= 335
Explanation:
a).
= (67×10)÷2
= 670 ÷ 2
= 335
So, 5×67 = (67×10)÷2
=> 335 = 335
b).
= (67x2)+(67×2)
= 134 × 134
= 268
So, 5×67 ≠ (67x2)+(67×2)
=> 268 ≠ 335
c).
= (6 ×7)×5
= 42 × 5
= 210
So, 5×67 ≠ (6×7)×5
=> 210 ≠ 335
d).
= (5×6)+(5×7)
= 30 + 35
= 65
So, 5×67 ≠ (5×6)+(5×7)
=> 65 ≠ 335

Answer: D
Step-by-step explanation:
because 320/4 = 80 mi/hr because it can not km or min and hr^2 would not make any sense
