X+ 3y = 13
(y - 3) + 3y =13
4y - 3 = 13
4y -3 + 3 = 13+3
4y = 16
4y/4 = 16/4
y=4
x = 4 - 3
x = 1
A) (1, 4)
Check x+3y =13
1+ 3(4) =13
1 + 12=13
13=13
The rate of change is ur slope.
The table : company p
y/x = 0.4/10 = 0.04
the graph : company s
y/x = 6/100 = 0.06
Company s (the graph) has the greatest rate of change
Answer:
r = c -km÷m
Step-by-step explanation:
C=( r+k) m (multiple the m with the letters in the brackets)
rm + km= c (cross the km over the equal sign and it will be a negative)
rm= c- km (then divide everything by my)
rm÷m = c - km÷ m
r = c- km÷ m
Answer: 9.19 ft
Step-by-step explanation:
Hi, since the situation forms a right triangle (see attachment) we have to apply the next trigonometric function.
Sin α = opposite side / hypotenuse
Where α is the angle of elevation of the ladder to the ground, the hypotenuse is the longest side of the triangle (in this case is the length of the ladder), and the opposite side (x) is distance between the top of the ladder and the ground.
Replacing with the values given:
Sin 45 = x/ 13
Solving for x
sin45 (13) =x
x= 9.19 ft
