The square in the graph represents one unit. In the diagram, the line has coordinates (0,4) and (4,0). Use the cpordinates, find the gradient and the equation using y = mx + c. So the equation of this line is x + y = 4. Now having obtained the equation of yhe line, the shaded part is below the line, therefore the inequality is : x + y =< 4
Answer:
b = 16
Step-by-step explanation:
16*x + b*x + 4 = 0
Solving for x we get:
x₁,₂ = - b ± √ b² - 4*a*c ] / 2*a (1)
If we take a look to the square root
√ b² - 4*4*16 = √ b² - 256
if we make √ b² - 256 = 0
b² = 256 ⇒ b = 16
Then equation (1) becomes:
x₁,₂ = ( - 16 ± 0 ) / 32
x = - 1/2
Answer:
1
Step-by-step explanation:
the y axis is the same the x axis is different by 1. because 7-6= 1
Answer:
D
Step-by-step explanation:
plug in the coordinates for x and y
We know that :
From the Figure :
Given : Height of the Tree = 10 m
Length of its Shadow = 17.3 m
⇒ 
⇒ 
⇒ x° = 30°
