Step-by-step explanation:
Given h(x) = -X – 1, solve for 2 when h(x) = -3.
Answer and Step-by-step explanation:
We are given the function h(x), which is equal to -x - 1.
We are told to solve for x and are given information the h(x) is equal to -3.
First, plug -3 in for h(x).
-3 = -x - 1
Second, add 3 to both sides, then add x to both sides.
-3 +(3 + x) = (-x - 1) +(3 + x)
(The 3's cancel out on the left, leaving the x, the x's cancel out on the right, leaving the -1 + 3, and -1 + 3 equals 2).
x = 2
When h(x) is equal to -3, x is equal to 2.

We know that diagonal of a square is equal to the diameter of circle
So, Given side of a square = 4 cmwe know diagonal of sqaure = √2 × side = 4 × √2 = 4√2 cm.So, diameter of circle = 4√2 cm.Hence, the required answer is = 4√2 cm.

Estimate the force needed for a 2.5 kg mass.
Answer:
F=ma
We need an acceleration to calculate a force. For now, we can only say that F = 2.5kg*a
Step-by-step explanation:
Mass alone tells us nothing about any forces on the object. 2.5kg is the same whether in space or next to a black hole. The forces would be quite different, however.

PLEASE HELP!! Please answer
Answer:
O x = 75, y = 68 (second option)
Step-by-step explanation:
74° = (x - 1)°
x - 1 = 74
x = 74 + 1
x = 75
40° + (y - 2)° + 74° = 180°
y - 2 = 180 - 40 - 74
y - 2 = 66
y = 66 + 2
y = 68

Help :C Two cities are 45 miles apart. Two trains, traveling at speeds of 70 mph and 60 mph, leave the two cities at the same time and travel in the same direction so that the faster train will catch up to the other one. How long after the trains leave will the distance between them be 10 miles? How long after the trans leave will they be 10 miles apart for the first time? Help :(
=======================================================
Explanation:
Draw a horizontal number line. Plot point A at 0 and point B at 45 on the number line. The distance from A to B is 45 units to represent that 45 mile gap between the cities.
Let's say the trains travel to the right (aka to the east) along this number line train track. We'll place the faster train at location A, and the slower train at location B. This allows the slower train a head start. Eventually the faster train will catch up. If this was swapped and the trains still aimed to the right, then the trains will never be 10 miles apart.
-----------------------
Now we'll define two variables
x = number of hours that have elapsedy = the train's location on the number lineFor the faster train at location A, which I'll just refer to "train A" from now on, we can form the equation y = 70x. I'm using the idea that distance = rate*time to help form this equation.
For example, if x = 2 hours have passed by, then train A is at location y = 70*2 = 140 miles on the number line train track.
Train B will have the equation y = 60x+45. The 60x is formed in a similar manner compared to the 70x. The plus 45 at the end is due to the 45 mile head start. In other words, train B travels 60x miles on top of the 45 miles already done so far.
-----------------------
The two key takeaways from that last section is that we have these equations
y = 70xy = 60x+45which correspond to the locations of train A and train B in that order.
Now to the question at hand: how can we determine when the trains are 10 miles apart? The short answer is through subtraction. Moreover, we'll need to involve absolute value to ensure that distance is never negative.
So the distance expression between the trains at any given time x is:
distance between trains = |trainA - trainB|
distance = |70x - (60x+45)|
distance = |70x-60x-45|
distance = |10x-45|
Next, we set that distance expression equal to 10 and solve for x.
distance = 10 miles
|10x-45| = 10
10x-45 = 10 or 10x-45 = -10
10x = 10+45 or 10x = -10+45
10x = 55 or 10x = 35
x = 55/10 or x = 35/10
x = 5.5 or x = 3.5
-----------------------
Those two results mean that at the hour marks of 3.5 hours and 5.5 hours is when the two trains are 10 miles apart exactly.
The two trains start off being 45 miles apart. They both take off and train A will catch up to train B. Their gap will be 10 miles at the 3.5 hour mark. That gap shrinks to 0 at some point, and then grows again afterward. By the 5.5 hour mark is when the trains are again 10 miles apart. This time is when train A is in the lead and will remain so assuming the speeds stay the same.
It seems like your teacher is only concerned with when the trains are 10 miles apart for the first time and not the second. So your teacher is likely only expecting one answer and that would be 3.5 hours
Side notes:
3.5 hours = 3 hours, 30 minutes = 210 minutes.5.5 hours = 5 hours, 30 minutes = 330 minutes.Multiply by 60 to convert from hours only to minutes only.10.0 x 0.01
----------------- =
0.01 x 0.01
10.0 x 0.01 0 . 1
----------------- = -------------
0.01 x 0.01 0 . 0001

if a domain is "all real numbers" can it be a function?
Hello!
Answer:
Yes
Step-by-step explanation:
Functions assign outputs to inputs. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited.
Hope this helps!
Answer:
Yeah
Step-by-step explanation:
you know real numbers are the combination of. the rational and irrational number so they domain over all other functions

Answer:
40°
Step-by-step explanation:
As per the provided information in the given question, we have :
∠AOC = 60°∠BOC = 3xAB is a straight line.We've been asked to calculate the measure of ∠BOC.
Here, ∠AOC and ∠BOC are making linear pair of angles.
[tex]\odot [/tex] Linear pair : Linear pair of angles are nothing but the two adjacent angles of which non-common arms are two opposite rays. Now, as these both angles are making linear pair so,
[tex] \longrightarrow \sf{\quad { \angle AOC + \angle BOC = 180^\circ }} \\ [/tex]
Substitute the measure of ∠AOC and the expression of ∠BOC.
[tex] \longrightarrow \sf{\quad { 60^\circ+ 3x = 180^\circ }} \\ [/tex]
Transposing the like terms.
[tex] \longrightarrow \sf{\quad {3x= 180^\circ -60^\circ }} \\ [/tex]
Performing subtraction of the terms in RHS.
[tex] \longrightarrow \sf{\quad {3x= 120^\circ }} \\ [/tex]
Now, transpose 3 from LHS to RHS, its arithmetic operator will get changed.
[tex] \longrightarrow \sf{\quad {x= \cancel{\dfrac{120^\circ}{3}} }} \\ [/tex]
Dividing 120° by 3.
[tex] \longrightarrow \quad\underline {\boxed{ \textbf{\textsf{ x= 40}}^\circ }} \\ [/tex]
∴ The value of x is 40°.
[tex] \underline{ \qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad} \\ [/tex]

2) <3 and <4 are complementary angles. If m<23 = (x + 24)° and m<4 =(x)º, then
find the measures of these angles.
Answer:
angle 3: 57; angle 4: 33
Step-by-step explanation:
because they are complementary angles they add up to 90 so we set the equation up like this
x + 24 + x = 90
after combining like terms and subtracting 24 from each side you get this
2x = 66
when you simply you get this
x = 33
angle 3 is 57 when we add and angle 4 is 33

Write down the lower and upper bounds of the number.
A number, truncated to 1 decimal place, is equal to 15.4
Write down the lower and upper bounds of the number.
Answer:
Step-by-step explanation:
truncated means when its rounded up from the lower bound and upper bounds meaning lower bound=15.4 and upper bound=15.5
The lower and upper bounds of the number are 15.4 and 15.5 respectively.
Given data:
When a number is truncated to 1 decimal place, it means that only the first decimal digit is considered, and the rest of the decimal places are discarded. In this case, the number truncated to 1 decimal place is 15.4.
The lower bound of the number is the largest number that rounds down to 15.4 when truncated to 1 decimal place. Since 15.4 is already rounded down, the lower bound is simply 15.4.
The upper bound of the number is the smallest number that rounds up to 15.4 when truncated to 1 decimal place. The next number that rounds up to 15.4 is 15.5.
Hence, the lower bound is 15.4 and the upper bound is 15.5.
