Answer: -4,-3

Step-by-step explanation:

You start at the point (1,4) on the coordinate plane. The first number is on the x-axis, which moves horizontally and is divided down the middle by the y-axis. The left side of the x-axis is negative, while the right side of the x-axis is positive. The second number is on the y-axis, which moves vertically and is divided in half by the x-axis. The upper half of the y-axis is positive, while the lower side of the y-axis is negative.

If you start at the point (1,4) then the x coordinate would be 1 and the y coordinate would be 4. So moving left by 5 units you would be subtracting 5 from the x coordinate. Similarly, by moving down seven units you would be subtracting 7 from the y coordinate.

Solve:

1 - 5 = -4

-4 is your x coordinate

4 - 7 = -3

-3 is your y coordinate

The coordinate (-4,-3) is your answer

Answer:

If there are 13 guests, it would cost Norma $26

Step-by-step explanation:

Since 12 guest equals 24 dollars all you have to do is divide 24/12 which would give you 2dollars. this means that she has to pay 2 dollars per guest. Multiply 13 becuase you want to know how much money it would cost with 13 guests and you get 26 dollars. Hope this helps.

Answer:

It'll cost $26 !

Step-by-step explanation:

if you set it up like this;

[tex]\frac{13}{x}= \frac{12}{24}[/tex]

you can see a few ways of solving this !

one way is cross multiplication .

13 x 24 = 312

312 / 12 = 26

Answer:

C. IV

Step-by-step explanation:

All the points on the graph have an x value of -3

Answer:

H

Step-by-step explanation:

H is the answer because in the simplest and easy way I can explain this is that it does have the same x in the table. If you look at F the x 0 repeats twice in the third and forth point. If you look at G the x -3 repeats twice in the first and second point. If you look at J the x 2 repeats twice in the first and forth point. The only answer choice does repeats any of the x's is H with the x's of -4, -2, -1, and 3. So with this being said H is the answer.

The y can repeat as a function just not the x.

Answer:

Rajeev is incorrect.

Step-by-step explanation:

Rajeev has 26 (4+12+10) plants in his home. Catarina has 25 (12+9+4) plants in her home.

From this, we get:

4+12+10 > 12+9+4

because:

26>25

So, Rajeev has more plants than Catarina, rather than the same amount.

You could use the bolded inequality to show your thinking.

Answer: 3) [tex]\sqrt{5}[/tex]

Step-by-step explanation:

Radical Form and Exponent Form

A radical can be expressed as a rational exponent following the identity:

[tex]\displaystyle \sqrt[m]{x^n}=x^\frac{n}{m}[/tex]

We should also recall that:

[tex](x^n)^m=x^{nm}[/tex]

We are given the expression:

[tex]\displaystyle \left(5^{\frac{3}{4}}\right)^\frac{2}{3}[/tex]

Applying the power of power:

[tex]\displaystyle \left(5^{\frac{3}{4}}\right)^\frac{2}{3}=\left(5^{\frac{3}{4}\cdot \frac{2}{3}}\right)[/tex]

Simplifying:

[tex]\displaystyle \left(5^{\frac{3}{4}}\right)^\frac{2}{3}=5^{\frac{1}{2}}[/tex]

Converting to radical form:

[tex]\displaystyle \left(5^{\frac{3}{4}}\right)^\frac{2}{3}=\sqrt{5}[/tex]

Answer: 3) [tex]\sqrt{5}[/tex]

Answer:

11. B      12. B, C, and D

Step-by-step explanation:

A = Rational numbers

B = Integers

C = Whole numbers

D = Natural numbers

E = Irrational numbers

11.  B

60/15 is a natural number because it equals 4 and is a positive integer

12. B, C, and D

An integer is a whole number meaning that because B. 42/6 = 7, C. 2√100 = 10, and D. 8 are all not fractions or decimals, they are integers.

Answer:

An Overview of the Cell Cycle. The most basic function of the cell cycle is to duplicate accurately the vast amount of DNA in the chromosomes and then segregate the copies precisely into two genetically identical daughter cells. These processes define the two major phases of the cell cycle.

Let, speed of 1st bicyclist is x.

So, speed of 2nd bicyclist is x-3 .

We know, relative speed when two objects moves towards each other :

[tex]v = x + ( x-3 )\\\\v = 2x - 3[/tex]

Now, distance travelled in 3 hours is (98-2) miles .

So,

[tex]2x-3 = \dfrac{96}{3}\\\\2x - 3 = 32\\\\2x = 35\\\\x = 17.5\ mph[/tex]

Therefore, speed of bikes are 17.5 mph and 14.5 mph.

Hence, this is the required solution.

Answer:

Step-by-step explanation:

So initially you have a square piece of metal, 15" x 15". You cut out squares from the corners of each side with side length x.

So you'll have a sheet that looks something like this now (assuming the formatting works):

   _____

__|       |__

|               |

|__        __|

   |____|

Your original side length was 15, but it has now been reduced by x on each side, so you're now going to have a new side length of 15 - 2x

When you fold the box up, the box will have a height of just x.

So you have a base with lengths (15 - 2x) and (15 - 2x), and a height which is just x.

V = l*w*h

So

V = (15 - 2x)(15 - 2x)(x)

= 225x - 60x^2 + 4x^3

Hope this helps

3 purple : 1 white

30 arangement will need so

minimum will need (3+1)=4 flowers per 30 arangements =120 flowers

minimum will be (90 purple: 30 white)

Answer:

120 flowers

Step-by-step explanation:

3 purple: 1 white

We know he wants to make 30 arrangement so

1 x 30=30 white flowers

3 x 30=90 purple flowers

30 + 90=120

Answer:

The average change in water level is: -3/4

Step-by-step explanation:

The average is calculated by adding up all the values and then dividing the sum by total number of values.

Given values are:

3/4, -9/4, -11/4, 5/4

The sum of values will be:

[tex]=\frac{3}{4}+(-\frac{9}{4})+(-\frac{11}{4})+\frac{5}{4}\\=\frac{3}{4}-\frac{9}{4}-\frac{11}{4}+\frac{5}{4}\\=\frac{3-9-11+5}{4}\\=\frac{-12}{4}\\=-3[/tex]

Total number of values is 4

So,

[tex]Average = \frac{Sum}{Values}\\= \frac{-3}{4}[/tex]

Hence,

The average change in water level is: -3/4

Answer:

99 marks

Step-by-step explanation:

Let 'x' be the mark in final exam

Sum of all the data's/ Number of data's = Mean

[tex]\frac{65+83+93+x}{4}=85\\\\\\\frac{241+x}{4} = 85[/tex]

241 + x  = 85*4

241 + x = 340

       x = 340 - 241

x = 99

Answer: = UwU

Step-by-step explanation:

Answer:

5u

Step-by-step explanation:

Simplifying

5u + -1u = u + 15

Combine like terms: 5u + -1u = 4u

4u = u + 15

Solving for variable 'u'.

Move all terms containing u to the left, all other terms to the right.

Add '-1u' to each side of the equation.

4u + -1u = 15 + u + -1u

Combine like terms: 4u + -1u = 3u

3u = 15 + u + -1u

Combine like terms: u + -1u = 0

3u = 15 + 0

3u = 15

Divide each side by '3'.

u = 5

Simplifying

u = 5
