Answer:
25
Step-by-step explanation:
Let us assume that m<1 nad m<2 are supplementary. Since the sum of supplementary angles is 180degrees, hence;
<1 + <2= 180
123+2x+7 = 180
130+2x = 180
2x = 180 - 130
2x = 50
x = 50/2
x = 25
Hence the value of x is 25
Answer:
a) 3 people will need 35 days to paint the bridge
b) p=105/t
Step-by-step explanation:
a)
We have 7 people each one is to work 15 days, so the bridge needs a total of 7(15) days of work
7(15)=105
Then we have 3 people each one is to work t days, altogether should do a total of 105 days of work
3(t)=105
Solve for t
t=35
b)
Substitute p for 3 in the second equation
p(t)=105
Solve for p
p=105/t
(x - 4)² = 25
x - 4 =
√25
x - 4 =
5
x = 5 + 4 or x = -5 + 4
x = 9 or x = -1
Method Use : Completing the square-------------------------------
Answer: x = 9 or x = -1-------------------------------
Answer:
Option B True
Step-by-step explanation:
we know that
A function relates <u>each element</u> of a set (input) with <u>exactly one</u> element of another set (output)
1) "...each element..." means that every element in X (input) is related to some element in Y (output)
2) "...exactly one..." means that a function is single valued. It will not give back 2 or more results for the same input
therefore
f(x) is a function
