What is a straight line?A straight line is an endless one-dimensional figure that has no width. It is a combination of endless points joined both sides of a point and has no curve.
Here, we have to points (1.5,0) and, (0,-3)
So, by using the formula of equation of straight line of two-point form, we get,
(y-y_1)/(x-x_1 )=(y_2-y_1)/(x_2-x_1 )
=>3x-1.5y=4.5
y=2x-3
Again,
Here, we have to points (-1.5,0) and, (0,-3)
So, by using the formula of equation of straight line of two-point form, we get,
(y-y_1)/(x-x_1 )=(y_2-y_1)/(x_2-x_1 )
=>3x+1.5y=-4.5
y=2x+3
Here, we have to points (1.5,0) and, (0,-3)

=>-3x+1.5y=4.5
y=-2x+3
Here, we have to points (-1.5,0) and, (0,3)

Step-by-step explanation:
A fruit punch recipe uses 4 cups of orange juice for EVERY 1 cup of cranberry juice.
This means that if i wanted 2 cups of cranberry juice, i also need double the amount of orange juice, which would be 8 cups.
In this way we can say the ratio of orange juice to cranberry juice would be 4:1.
This is the same as saying for every 1 cup cranberry juice, we need 4 cups orange juice . This is written as 1:4

What is the equation of the line that passes through the point (-2,0) and has a slope of -2
Answers
Answer:
y = -2x -4
Step-by-step explanation:
The equation of a line is y = mx + b, where m is the slope of the line, and b is the y-intercept. We are told that the slope of the line is -2, so we can start with
y = mx + b
y = -2x + b
We can figure out the value of b by plugging in the coordinates of the point given (-2, 0)
0 = -2(-2) + b
0 = 4 + b
Subtract 4 from both sides of the equation
-4 = b
Then plug that value of b back into the equation above:
y = -2x + (-4) or y = -2x -4
Answer:
y=mx+c
we will find c
0=(-2)(-2)+c
c=-4
y=-2x+(-4)
y=-2x-4
2x+y+4=0
An international calling plan charges a rate per minute plus a connection fee. You can make a phone call from France to the United States for $0.22 per minute plus a $0.99 connection fee. Write a linear equation that could be used to represent the cost of an x minute phone call.
Answers
Answer:
y=0.22x+0.99
Step-by-step explanation:
Notice that in this problem they are giving us a rate $0.22 per minute. This means that whenever we multiply that rate by the number of minutes used, we will get the total amount of money spent. In this case, since we don't know the amount of minutes (variable) we will call them x, so the first part of the equation should be:
0.22x
the connection fee is $0.99, which means that no matter the time you take talking by the phone, you will be charged a constant value of $0.99, so we can add that to the previous value we got:
0.22x+0.99
and for the equation to be complete, we can set variable y= to the total cost of the call, so the whole equation would be:
y=0.22x+0.99

→Now, back when I was a kid, the closest thing to sending an e-mail was tying a note to a pigeon and throwing him in the direction of the person you wanted to talk to. I never thought in a million years that I'd be sued for illegally downloading music.
I was doing my morning crossword puzzle, enjoying my coffee and prune juice, when the mailman knocked on my door. I got some not-so-good news in a letter from a company called the Recording Industry Association of America, or the RIAA for short. They're the folks who represent record companies and their performers. They told me in this pretty, pink stationery that I was violating copyright laws by downloading music off the Internet, and they weren't too happy about it. Copyright laws are these doohickeys that give artists, writers, or musicians control over how their work is used and reproduced. Apparently, today, downloading music is like when we used to steal a pie off old Ms. Roundtree's windowsill. But, rather than a paddle to the keister, the RIAA will sue your keister.
Now, the funny thing is, I didn't even know I had connection to the Internet, let alone how to download a song by P-Doody, or whatever that wisecracking young man's name is. So, I had a talk with my grandkids (whom I've nicknamed Up To and No Good) after this little runabout with the law, because I have a sneaking suspicion that they might have something to do with this.

Question 8: Ramiro is correct because the triangles are similar by AA (the measure of angle C in triangle ABC is 180-62-39=79 degrees). Julie is wrong because you would need at least 1 pair of corresponding congruent sides to prove the triangles congruent (angles alone are not sufficient)
The question with the angle diagram:
Since angles A and B are supplementary (since they form a linear pair), their measures add to 180 degrees. Hence, the measure of angle B is 180-140=40 degrees.
The measure of angle E can be found by the same logic, and has a measure of 50 degrees.
Since the sum of the measures of the angles of a triangle is 180 degrees, the measure of angle C is 180-40-50=90 degrees.
Hence, since angles C and D are supplementary, angle D has a measure of 90 degrees.

Volume of the figure = volume of triangular prism + volume of trapezoidal prism = 497 m³.
What is the Volume of a Prism?Volume of any prism = Base area × height of the prism
Thus:
Volume of the figure = volume of triangular prism + volume of trapezoidal prism
Volume of triangular prism = 1/2(b×h)×L = 1/2(8 × 4) × 14
Volume of triangular prism = 224 m³
Volume of trapezoidal prism = 1/2(b1+b2)×h×L = 1/2(8 + 5) × 3 × 14
Volume of trapezoidal prism = 273 m³
Volume of the figure = 224 + 273 = 497 m³.

Multiplicative inverse of (7/3)^-3
Answers
Hello.
First, let's calculate
[tex]\tt{\displaystyle(\frac{7}{3}) ^{-3}[/tex]
Remember the Properties of Exponents:
If we have a number to a negative power, we flop the number over:
[tex]\tt{a^{-b}=\displaystyle\frac{1}{a^b}[/tex]
Now, let's use this property to simplify our expression.
Flop the number over:
[tex]\tt{\displaystyle(\frac{3}{7} )^3[/tex]
Now, we should recall another property of exponents:
[tex]\tt{\displaystyle(\frac{a}{b} )^m=\frac{a^m}{b^m}[/tex]
Since we have a fraction to a power, we should raise both the numerator and the denominator to the power:
[tex]\tt{\displaystyle\frac{3^3}{7^3}[/tex]
3 cubed is 9, and 7 cubed is 343:
[tex]\tt{\displaystyle\frac{9}{343}[/tex]
Now, the multiplicative inverse of that number is simply that number flopped over:

Answer:
this is how!!!
Step-by-step explanation:
so since it says “unit price” (also says dollar per bananas) all you have to do is make a variable and substitue
So:
Let number of bananas be “ b “
0.50b
0.5(4)
2
2 dollars
It the same for the rest except the last two
Since you dont know the number of bananas, let b be unknown, but may it equal to the cost given. For example:
10 = 0.5b
Since you dont know b
To solve for b, you have to make b be all by itself (like me when my cousin is sleeping on the other side of the world ;’) )
To do that you have to divide 0.5 to both sides
10 / 0.5 = 0.5b / 0.5
This will remove 0.5 from the right side and isolate b
Since b and 0.5 are being multiplied you can factor 0.5 out from the right side
10 / 0.5 = b
Now simplify
B = 20 bananas

Why is he wrong?
Answers
Answer:
He is wrong since reflecting the image across the x-axis means reflecting it on the axis that is horizontal and reflecting it over the y-axis means reflecting it on the y-axis which is verticle.
Answer:No, it would not be the same if you reflect it from the X axis.
Step-by-step explanation:
because the the shape is not "on" the X axis. When you reflect the shape across the X axis, then you will not really get a shape. It's easier if you imagine you put a mirror on the x axis and looked at it. Malik would have to shift the whole shape down so that the current points (3,1) and (-3,1) would change to (3,0) and (-3,0) Also shifting down the other two points too. Reflecting it is like if you had the shape in paper and you folded it in half. If it matches perfectly, then you know that you have a match and that it is reflecting. If it doesn't fold perfectly, then it doesn't reflect. So if you folded the shape from the X axis, you wouldn't get a perfect match so he is wrong. Does it help?

Where:
m is the slope, and b is the y-intercept
All you really have to do here is replace m with 1/2, which is the slope you gave, and replace b with -5, the y-intercept you gave, in the equation y=mx+b. And you will get y = 1/2x-5
