Step-by-step explanation:
Red taxi : y = 2x + 2
Green taxi : y = x + 5
Y are the costs of a ride, X are the miles of a ride.
The y-intercepts are the cost of just getting into a cab.
So, that is $2 for a red cab and $5 for a green cab.
Every mile with a red cab costs $2, while every mile with a green cab costs $1.

Graph the linear function w(x) = 3/5x + 2
Answer:
Coordinates or points would be (0,2), (1,2.6) (2,3.2) (3,3.8)
Step-by-step explanation:
Formula
w(x) = 3/5x +2 in each coordinate I have a x so for example 3.
I would rewrite this as 3/5(3) + 2
w(x) = 3/5x +2
w(3) = 3/5(3) + 2
y = 1.8 + 2

What is the slope of this line?
y=−13x+14
A. -1/3
B. 1/4
C. 1/3
Answer:
see below
Step-by-step explanation:
y = -13x+14
This is in slope intercept form
y = mx+b where m is the slope and b is the y intercept
The slope is -13 and the y intercept os 14
If you mean y = -1/3x + 1/4
The slope is -1/3 and the y intercep is 1/4
Answer:
-1/3 is the slope because the equation is in a form of y =mx + c, where m is the slope

Hello my name is Galaxy and I'll be helping you today. I hope you are having a nice day!
Simplification
To figure out how we can order them, we can first simplify the problems so that we can easily determine its place. We can put the fractions into decimal form so that they are are in one form and will be easy for us to comprehend.
[tex]\frac{19}{5}=3\frac{4}{5}=3.80[/tex]
We know that [tex]\frac{1}{5}[/tex] is equal to 0.20 because we know that 1.00 will be equal to 100 in this case and we can divide that by five to get 20 which will be divided back to get to 0.20.
As I've explained how I've simplified the first one, simplifying the others should be a quite similar process, feel free to comment below if you need any assistance with this.
[tex]\frac{19}{5}=3.80\\1.62=1.62\\\frac{-14}{3}=-4.6667\\ -0.5=-0.5[/tex]
(Everything simplified to decimal form.)
We can now proceed to ordering them.
Ordering
Ordering decimals doesn't have to be as hard as it looks, we know that as per the number line a number that is more negative (e.g. -37) will be less than (e.g. -5) as it is closer to the number 0.
Now that we know how to order the negative numbers, we can order them into order, and for ordering the positive numbers, we should already know how to do that.
So, now, in order from Greatest to Least. We can order them by what I said above.
[tex]3.80>1.62>-0.5>-4.666[/tex]
We can convert the numbers back into their original form by looking at how we converted them in the Simplification section.
Final Answer
After converting them into a way that we can comprehend, we get our final answer in terms of greatest to least as:
[tex]\frac{19}{5}>1.62>-0.5>\frac{-14}{3}[/tex]

last time i'm asking about this bc i keep getting this wrong!!
I need help with these. I have no idea how to find the answer for them. My teacher told me the first one was 136 but she didn’t explain how to find the answer or anything. Can someone please explain how you get the answers step by step & not just give them to me. Thank!
Answer:
136
55
53
70
Step-by-step explanation:
1) here x and 136 are alternate interior angles and they are equal
2) here x and 125 lie on the same straight line
so x + 125 = 180
x = 55
3) here 53 and x are corresponding angles and they are equal
x = 53
4) for this see picture below
side angle to 110 becomes x because of corresponding angles
and as this x and 110 lie on same line
x + 110 = 180
x = 70
Answer:
A) If a line crosses 2 parallel lines, then each angle it forms with the first line is the same angle on the second line. And when 2 lines crosses, the opposite angles are the same.
B) x is 180° - 125° = 55°
C) x is 53° (If a line crosses 2 parallel lines, then each angle it forms with the first line is the same angle on the second line.)
D) x is 180° - 110° = 70°

The ratio of two numbers is 4:9. When 5 is subtracted from each of them ,the now 38. Find the numbers
Given : The ratio of two numbers is 4:9. When 5 is subtracted from each of them the ratio is 3:8. Find the numbers
Need to Find : The numbers
Solution : According to the question here we are given that the ratio is 4:9 and 5 is subtracted from each of these ratios after which the ratio becomes 3:8. Let's follow the steps to get the answer.
Let the constant multiple be x
Now, according to the question:
The numbers are 4x and 9x
As we get to know that each of them is subtracted by 5. So,
1st number = 4x - 5
2nd number = 9x - 5
New ratio becomes 3:8
⇢ (4x - 5)/(9x - 5) = 3/8
⇢ 8(4x - 5) = 3(9x - 5)
⇢ 32x - 40 = 27x - 15
⇢ 32x - 27x = - 15 + 40
⇢ 5x = 25
⇢ x = 25/5
⇢ x = 5
Now, getting the numbers. Instead of x we need to put 5 and multiply with the constant.
1st number = 4x = 4(5) = 20
2nd number = 9x = 9(5) = 45
∴ The numbers are 20 and 45 respectively.

A barrel of oil was filled at a constant rate of 7.9 gal/min. The barrel had 12 gallons before filling began.
The equation that models this situation is z = 7.9y + 12.
A linear equation is a function that has a single variable raised to the power of 1. An example is x = 4y + 2.
Where:
2 is the constantx = dependent variable y = independent variableFrom the equation given, 12 would be the constant, the independent variable would be 7.9 and z would be the dependent variable.
z = 7.9y + 12
Here is the complete question: A barrel of oil was filled at a constant rate of 7.9 gal/min. The barrel had 12 gallons before filling began. write an equation in standard form to model the linear situation.

Is it all clear?
Please answer this for me!! Thank you!
Answer:
B
Step-by-step explanation:
Okay, so we know all answers that apply, so why did I pick only one answer?
Think of a graph: have you heard of y = mx + b? even if you haven't the m is slope and b is y-intercept. You can use this to graph.
So if you have same slope and y-intercept you'll get infinite solutions
So if you don't know y = mx + b? it's ok! You're basically looking for the same thing on both sides. When it's the same, they'll cancel out.
Hopefully this helps! You may want to ask your teacher to make sure. :))

Answer:
30y+14
Step-by-step explanation:
add the values of all the sides together: (5y+4) + (5y+4) + (10y+3) + (10y+3) = (5y + 5y + 10y + 10y) + (4 + 4 + 3 + 3)= 30y + 14

Answer:
[tex]k=\pm3[/tex]
Step-by-step explanation:
[...] if you can write the LHS as a perfect square, or if you can't spot a factorization of it right away, if and only if the discriminant [tex]\Delta = b^2-4ac[/tex] (or, if b is an even number, 1/4 of it) is zero.
I see it! I see it!
Stare at it for a while. First term is [tex]3(2x)^2[/tex], third term is [tex]3(1)^2[/tex], we are missing a double product, but we can play with k. For the LHS to be [tex]3(2x\pm1)^2 = 3(4x^2\pm4x+1) = 12x^2\pm12x+3[/tex] you just need [tex]4k= \pm12 \rightarrow k=\pm3[/tex].
I don't see it...
Then number crunching it is. Set the discriminant to 0, solve for k
[tex]\frac{\Delta}4 = 4k^2-12\cdot 3 =0 \rightarrow 4k^2=36 \\k^2 = 9 \rightarrow k=\pm3[/tex]
