Answer:
Step-by-step explanation:
a line parallel to the equation would have the same slope (7/8)
so what we know so far is
y = 7/8x + b
since it has to go through point C (-4, 8)
we’ll plug in those values for x and y (x = -4, y = 8)
8 = 7/8(-4) + b
8 = -28/8 + b
8 = -3.5 + b
b = 11.5
so the equation is
y = 7/8x + 11.5
Answer:
38°
Step-by-step explanation:
The measure of required angle can be obtained by using cosine law.
From the given triangle we find that:
a = 5, b = 3, c = 7,
Since,
cos (A) = (b^2 +c^2 - a^2) /2bc
Therefore,
cos (A) = (3^2 + 7^2 - 5^2) /(2*3*7)
cos (A) = (9 + 49 - 25) /(42)
cos (A) = (33) /(42)
cos (A) = 0.785714286
A = arccos(0.785714286)
A = 38.213210675°
A = 38°
M=-20/7. .........!!!!!!!!
Answer:
7x3=21
Step-by-step explanation:
7+7+7=21, 7x3=21
5x + 6 = 1
Subtract 6 from both sides.
5x = -5
Divide from both sides.
x = -1 (ANSWER)
hope this helps!!
