Answer:
1). t ≥ -
2). k ≥
3). y < -
4). b >
5). w ≤ 0
Step-by-step explanation:
1).
t ≥ -
2). 15k + 11 ≤ 18k - 5
15k - 18k ≤ -5 - 11
-3k ≤ - 16
3k ≥ 16
k ≥
3). 44y > 11 + 88y - 22y
44y > 11 + 66y
44y - 66y > 11
-22y > 11
22y < -11
y <
4).
(b - 27) >
b >
b >
5). 11w - 8w ≥ 14w
3w - 14w ≥ 0
-11w ≥ 0
w ≤ 0
times by a on both sides
a(a+8)= -5
expand brackets
a^2 + 8a = -5
minus 5 on both sides to set equal to 0
a^2 + 8a -5 = 0
use quadratic formula to get 2 solutions

Answer:
Step-by-step explanation:
we know that
The linear equation in slope intercept form is equal to
where
m is the slope
b is the y-intercept
<em>Find the slope</em>
The formula to calculate the slope between two points is equal to
take the points
(0,2.5) and (100,97.5)
substitute in the formula
Find the y-intercept b
we have
substitute i the linear equation
solve for b
Note It was not necessary to calculate the value of b because the value is given in the table
Remember that the y-intercept is the value of y when the value of x is equal to zero (the y-intercept is the point (0,2.5))
The linear equation is
Answer:
9 feet away
Step-by-step explanation:
40²+b²=41²
1600+b²=1681
b²=81
b=9
7x^21 so u do 7*7*7*7 , or do 7+7= 14 then do 7+7= 14 add 3 7's for exponent
