Write the equations using point slope form. Then put into slope intercept form. (3,-4), m=2 and (-5,1), m=4/3
Answer:
Y= 2x + 10
Y= 4/3 x + 7 2/3
For the first equation with points (3,-4) and m there are three values that we can plug into the equation y=mx + b to find the missing value in this situation, the y-intercept.
First, write the equation with the given values and you should have something like this:
-4 = 2(3) +b
The only value that hasn't been discovered yet is b so we solve the equation appropriately to get our value.
-4 = 6+ b
-10= b
And now that we know that the value of b is -10 we can plug -10 into the equation and get the equation Y= 2x + 10
Now for the second, we complete the same steps. We know that we have the points and the slope and subsequently plug it into the equation and receive our answer( for the y-intercept).
1= -5(4/3) +b
1= - 6 2/3 + b
7 2/3 = b
Once we see that the value of b is 7 2/3 we plug it into the equation and get Y= 4/3x + 7 2/3

Shreya has a photo that is 16 cm tall and 20 cm wide. She wants to put a frame around the photo which would have the same width all around.
Represent the area of the whole frame as a polynomial in terms of the width around the photo.
A.[tex]x^{2} + 36x + 320[/tex]
B.[tex]-4x^{2} - 72x + 320[/tex]
C.[tex]4x^{2} + 72x + 320[/tex]
D.[tex]-x^{2} - 36x - 320[/tex]
A photo is usually rectangular in shape. This means that if a frame is to be put around the photo with the same width all round, it means that if the width is "x", then the new length and width will be (l + 2x) and (w + 2x) respectively where l is length and w is width.
Option C is the correct answer
Data Given;
Height of Photo: 16 cm
Width of Photo: 20 cm
Since she wants to put a frame with same width around the photo, let's represent this width as x.
Thus;
New height = 16 + 2x
New width = 20 + 2x
Area of a rectangle is given as:
A = Length * width
Thus, in this case;
A = (16 + 2x) × (20 + 2x)
Multiplying out, we have;
A = [tex]4x^{2} + 32x + 40x + 320[/tex]
A = 4[tex]x^{2} + 72x + 320[/tex]
Looking at the given options, Option C is the correct answer

E15 gasoline contains 15% of alcohol calculate the volume in liters of alcohol in a full 20 gallon gas tank
Since, 1 gallon = 3.78541 liters
Therefore, 20 gallons = 75.7082 liters
That means amount of gasoline in the gas tank is 20 gallons or 75.7082 liters.
It's given in the question that E15 gasoline contains 15% of alcohol.
Therefore, amount of alcohol in the gas tank = 15% of 75.7082

You choose to tip a taxi driver 20%. if the tip is $2.00, how much was the original cost of the ride?
A grocery store sign indicates that bananas are 3 for $1.50, and a sign by the oranges indicates that they are 5 for $3.00. Find the total cost of buying bananas and 4 oranges.
PLEASE ANSWER THANK YOU
Answer:
Below
Step-by-step explanation:
1. To find the percentage of a number you would need to multiply it by 0. whatever the percent. In this case we are given the percentage and the tip amount, so we can find the original cost of the ride like this :
2 = 0.2 (x)
Multiply both sides by 10
20 = 2x
Divide both sides by 2
10 = x
The original cost of the ride was $10
2. For this one we already know the cost of the 3 bananas so all we need to find is the cost of 4 oranges
Each orange = $3.00 / 5
= $0.6
For 4 oranges, it would be 0.6 x 4 = $2.4
Adding the price of 4 oranges and 3 bananas together....
2.4 + 1.5 = $3.9
The total cost of buying 3 bananas and 4 oranges is $3.9

Marcus is tying two bows for birthday gifts. He uses 3 3/8 feet of ribbon for Crystal's gift and 2 3/4 feet for Tim's gift. If he has an 8-foot roll of ribbon, how much will Marcus have left over?
Marcus will have [tex]1\frac{7}{8}[/tex] feet as left-over.
It is important we understand that foot refers to single unit of measurement while feet is the plural of foot.
Marcus needs to tie two bows for birthday gifts and he has an 8-foot roll of ribbon.
• He uses 3 3/8 (27/8 as a fraction) feet of ribbon for Crystal's gift.
• He uses 2 3/4 (11/4 as a fraction) feet for Tim's gift.
The left-over computation is as follows:
= [tex]8 - \frac{27}{8} - \frac{11}4}[/tex]
= [tex]\frac{256-108-88}{32}[/tex]
= [tex]\frac{60}{32}[/tex]
= [tex]\frac{15}{8}[/tex] or [tex]1\frac{7}{8}[/tex] feet
Marcus will have [tex]1\frac{7}{8}[/tex] feet as left-over.

find the smallest value of k, such that 525k is a perfect cube
Answer:
why should the government provides security to it's people
Answer: 2205
Step-by-step explanation:
From the prime factorisation of 525 we get
525 = 3×5×5×7
We have to make sure that all the factors are in cube form
To do that we have to add 3×3×5×7×7 to the factors
We get
525 = 3×3×3×5×5×5×7×7×7
So the 3×3×5×7×7 gives us the smallet value of k, which is 2205
And 525×2205 gives us 1157625 which is a perfect cube.
