Answer:
Step-by-step explanation:
so these two lines cross at some point.. and they want to know the y point at which they cross... sooo..
solve them as a system to find the points that are common to both
Eq. 1) 5x -2y = 16
Eq. 2) -4x+6y=-15
i'll use the elimination method as these equations "lend" themselves to that way.. they are easy to solve that way .. in other words..
multiply Eq. 1 by 3 the add Eq. 2 .. to it... add the terms as columns....
15x-6y = 48
<u> + ( -4x+6y=-15)</u>
= 11x+ 0y =33
x=3
nice, now plug 3 in for x in one of the Eq. try Eq. 1
5(3)-2y=16
15-2y=16
-2y =1
y = 
since we're looking for the y coordinate... that's your answer 
Answer:
x = −3
Step-by-step explanation:
The equation is
log(2x + 6) + 8 = 3
We combine first subtract 8 on both sides
log(2x + 6) + 8-8 = 3 -8
log(2x + 6) = -5
The log is to base 10
Thus;
10 ⁻⁵ = 2x + 6
0.00001 = 2x + 6
2x = 0.00001 -6
2x = -5.99999
Dividing both sides by 2
x = - 2.999995
<u> ≈ - 3</u>
Answer:

Answer:
d option
Step-by-step explanation:
Area of rectangle = length × breadth
Placing the values,
143 m² = length × 6.5 m
length = 143 m²/6.5 m = 22 m.
