If you were going to solve -3(x + 5) = 27, what is the first step that you would do? Why did you start there?
Answers
Answer:
Step-by-step explanation:
Multiply -3 for x and for 5
-3x-15=27
When you have this type of equation the first thing you do is take off the parentesis
Then you pass the 15 to the other side and you get -3x= 27 +15 . After that you divide that for -3 and you get the x . In this case x= -14

The length of the two legs of a right triangle are 18 cm and 24 cm.
What is the length of the hypotenuse of the triangle?
O A. 30 cm
OB. 36 cm
OC. 42 cm
D. 48 cm
Answers
Answer: 30 cm
Step-by-step explanation: Take note that ^2 means to the second power.
a^2 + b^2 = c^2 (hypotenuse)
18^2 + 24^2 = c^2
324 + 576 = c^2
900 = c^2
To find the length of c you have to find teh square root of 900.
√c^2 = √900
c = 30
The length of the hypotenuse is 30 cm!

Alysha’s average speed when walking home from the market was 5 mph, and it takes her 21 minutes longer than when she drives to the market. If she drives along the same route, at an average speed that is 8 times her average walking speed, how many minutes does it take her to drive home from the market?
Answers
9514 1404 393
Answer:
3 minutes
Step-by-step explanation:
Let x represent Alysha's time to drive home from the market.
Speed and time are inversely proportional to each other (for the same distance), so we have ...
(walking speed)(walking time) = (driving speed)(driving time)
5(x +21) = (8·5)(x)
x +21 = 8x . . . . . . . . . divide by 5
21 = 7x . . . . . . . . subtract x
3 = x . . . . . . .divide by 7
It takes Alysha 3 minutes to drive home from the market.

f(g(x))

Answers
Answer:
f(g(x)) = 3x + 1
Step-by-step explanation:
To find f(g(x)), substitute x = g(x) into f(x), that is
f(x + 1)
= 3(x + 1) - 2
= 3x + 3 - 2
= 3x + 1
A collect call costs $5.99 to connect plus 99 cents per minute. What is the cost of a 6 minute call?
Answers
Answer:
$11.93
Step-by-step explanation:
You can write an equation to represent this scenario, where x is the number of minutes spent on the call and y is the total cost of the call.
[tex]y=0.99x + 5.99[/tex]
Plug in 6 for x:
[tex]y=0.99(6)+5.99[/tex]
Multiply 6 x 0.99, representing the fact it costs 99 cents per each minute spent on the call:
[tex]y=5.94+5.99[/tex]
Add the sum of the $5.99 cost to connect the call, plus the charge ($5.94) for spending six minutes:
[tex]y=11.93[/tex]
Your answer is $11.93!

Question 2
Find three consecutive odd integers whose sum is 99.
Answers
Answer:
31, 33, 35
Step-by-step explanation:
Let 2n+1 be the first odd number. What will the next one be? Add two:
Let 2n+3 be the next odd number. Again, what is the next one? Add two:
Let 2n+5 be the third odd number.
The sum of those three numbers must be 99. You don't have to have the parenthesis here, but I think they help clarify where everything comes from.
(2n+1) + (2n+3) + (2n+5) = 99
Add like terms, and solve for n:
6n + 9 = 99
6n = 90
n = 15
The three odd numbers we want are:
2(15)+1 = 31
2(15)+3 = 33
2(15)+5 = 35
Double check: 31+33+35 = 99?

What is the difference between a system of equations and a system of inequalities?
Answers
Expressions can be expressed as equations or as inequalities.
The difference is that the variables in a system of equation have one solution each, while in a system of inequalities, the variables have a range of values.
Let the system of equation be:
[tex]\mathbf{ax + by = c}[/tex]
[tex]\mathbf{dx + ey = f}[/tex]
Let the system of inequality be:
[tex]\mathbf{ax + by < c}[/tex]
[tex]\mathbf{dx + ey > f}[/tex]
Both systems can be solved using the same method, such as: graphs, substitution and elimination.
However, the difference is that:
In a system of equation, the variables can have one solution each, while in a system of inequalities, the variables have a range of values.

(images to help with graph are below)
Step-by-step explanation:
okay! so once you get the hang of this, it is super super easy.
so the y-intercept is a point on that long line going up and down on the graph. it shows where the line intersects the middle!
so here it says that the y-intercept (y-int for short) is 2. so we will simply mark a little point on 2.
now the slope. the slope is -4. this can be written as -4/1. the -4 is on the top so i represents the y values. and the 1 is on the bottom so it represents the x values.
we know that when graphing, x goes from side to side and y goes up and down.
if an x value is positive you move it to the right (forwards), if it is negative you move it to the left (backwards). if a y value is positive you move it upwards, if it is negative you move it downwards. so we want to start graphing with our x.
The x value is 1 (because it is in the bottom of the slope! -4/1!). So we will move one point from the y-int (the point we marked).
Now for the y values. The y value is -4 (again, taken from the -4/1. the top number is the y value). FROM THE PLACE WE LEFT OFF FOR THE X VALUES (we left off at point (1,2) because we moved it one to the right!), we will move 4 points DOWN because it is negative (-4). Mark this place with a dot!
We should now have the points (0,2) and (1,-2) marked with a dot. draw a line through the 2 dots! this is ur finished graph. notice how the line intersects the middle on the y-intercept!! that will always happen.
Lastly, the equation! the formula for slope intercept form is y=mx+b
m is always your slope. b is your y-int. and y and x stay blank (for now. in the future you might use those spots). so simply fill in m and b!
the slope is -4. so m = -4
the y-int is 2. so b = 2
the finished equation should look like this:
y = -4x + 2
I hope this helped !!!
