Hello :
an equation is : y-5 = 0( x+7)...(the slope =0 '<span> horizontal line ' )</span> y=5
Step-by-step explanation:
-4(4x-9)=2x
-16x+36= 2x
-16x - 2x = -36
-18x = -36
x = 2
6x-8=13 start off with adding 8 to 13 then 6x=21 then divide 6 to both sides getting x=3.5
The two cars lying on one side of the plane are 50 meters apart.
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
let us assume that the height is 100 m. Let d represent the horizontal distance. For depression of 38°, Ф = 90 - 38 = 52°, hence:
tan(52°) = d / 100
d = 128 m
For depression of 52°, Ф = 90 - 52 = 38°, hence:
tan(38°) = d / 100
d = 78 m
Distance apart = 128 - 78 = 50 m.
