Answer:
(x,y) = (
,
)
Step-by-step explanation:
We have to find point of intersection of two lines.
the given equations of line are:
10x - 4y = 43 - (1)
-3x - 3y = -15 - (2)
Multiplying the first equation by 3 we have:
(10x - 4y = 43)×3 = 30x - 12 y = 129 - (3)
Multiplying second equation by 10 we have :
(-3x - 3y = -15)×10 = -30x -30y = -150 - (4)
Now, adding equation (3) and (4) we have:
-42y = -21
⇒ y = 
Now, putting this value of y in equation (1), we have
10x - 2 = 43
⇒ 10x = 45
⇒x = 
Hence, the intersection of given two lines is (x,y) = (
,
)
Answer:
angle y
58 + 38 + y = 180 (angle sum property)
96 + y = 180
y = 180 - 96
y = 84
angle x
x = 29 (58/2)
(angle subtended by an arc at centre is double the arc at any point on remaining part of centre)
the values of x = 29 and y = 84
Answer:
A. 4 B. log₂(2^4)
Step-by-step explanation:
A. log₂ 2 = log₂ 2¹ = 1
log₂ 8 = log₂ 2³ = 3
log₂ 2 + log₂ 8 = 1 + 3 = 4
B. *log₂ 2⁴ = 4
Answer:
-28
Step-by-step explanation:
Plugging in -6 as x we get 5(-6) + 2, which simplifies to -30 + 2 or -28.
