find the value of this expression if x= -7

x^2+5/x+1

Answer:

y=

Step-by-step explanation:

Perpendicular means opposite reciprocal of the slope. This means that the slope would change from 2/5 to 5/2 and add a negative, so it is -5/2.

y=-5/2x+b

2=-5/2 (2) +b

7=b

y=-5/2x+7

Answer:

Band A:y=700

Band B:y=550+1.50x

Step-by-step explanation:

Band A: since they are a fixed rate no matter how many students the equation  would be y=700 . There is no need for x since there is no extra price for students

Band B: Since this band charges 550 plus 1.50 per student we will need a x in our equation

y=550+1.50x

The difference between the two equations is that in Band B we need to add the price per student.

Answer:

2y^3x^7-3y

Step-by-step explanation:

I had the same problem on my test and got it right trust me

The expression 12(x⁷)(y³) divided by 6(x³)(y) is equal to 2x⁴y².

An expression that consists of variables, constants, and exponents that are combined using mathematical operations like addition, subtraction, multiplication, and division is referred to as a polynomial.

To simplify the expression, we can divide the coefficients and subtract the exponents of the variables with the same base.

Therefore:

12(x⁷)(y³) divided by 6(x³)(y)

= (12/6)(x⁽⁷⁻³⁾(y⁽³⁻¹⁾)

= 2x⁴y²

Therefore, 12(x⁷)(y³) divided by 6(x³)(y) is equal to 2x⁴y².

Step-by-step explanation:

Mathematically, the area of a triangle

A = 1/2 * b * h

b is base, h is height

For 12 square units, we can have a base of 6 and a height of 4

By tripling the dimensions for the second triangle, we will have a triangle of 18 by 12

So the new area is;

A = 1/2 * 12 * 18

That was how we got 108 square units

Letter A?

Answer:

For the chart, the missing number on top is 10. the bottom numbers are 1.5 then 9.

For the question, all of the numbers equal the ration 5:3.

Question 2: Yes. 30/x=2/4 which equals 60 (minutes) which is an hour.

Step-by-step explanation:

1A:

2.5 amount of water  - 1.5 amount of pasta

10 amount water - 6 amount pasta

15 amount water - 9 amount pasta

2.5 : 1.5

5 : 3

10 : 6

15 : 9

1B. these quantities are proportional because they can all be simplified to the same unit rate of 5 : 3.

2. Johnny is correct. The rate is 4 : 2, with a unit rate of 2 : 1. If you multiply both sides by 30 (how many inches deep the hot tub is) you get a ratio of 60 : 30, meaning it would take an hour to fill up the tub.

Answer:

x=-25

6x/5 - x = x/15 - 10/3

x/5 = x/15 - 10/3

3x = x - 50

3x - x = -50

2x = -50

x = -50/2

X=-25

Junior is 1 1/5 of his brother height

Junior = 1 1/5 of 1 1/2

= 6/5 × 3/2

= 6 * 3 / 5 * 2

= 18/10

= 1 8/10

= 1 4/5 meters

Step-by-step explanation:

Ok to start of lets identify the money in each bank account

I will not be using names to make this simpler.

Student A: $-100.54

Student B: $95.88

Student C: $50.00

Student D: $-120.37

Lets pretend that were not talking about money to help you understand this.

So just from glancing at this you'd think -120.37 would be the most because its the largest number correct?

Well you have to include the negative sign. The negative sign shows that this number is below 0.

Lets take a look at the other negative number.

-100.54

Greater or less than -120.37?

-100.54 is actually greater than -120.37

Why?

On a number line, the negative side, your counting back from 0. So the farther away you are from 0 for negatives, the less that number is.

So -120.37 would be the least and -100.54 would be the second least.

The greatest would be 95.88 because its greater than 50.

So the order would be 95.88, 50, -100.54, then -120.37

Just find which students that goes with and your done!

Step-by-step explanation:

Francice says 86 divided by 4 is 20 with a reminder of 6 she reasons it's correct because ( 4x20 + 6 = 86 what mistake did franchise make. ( if you can answer this ill give you 40 brainless.

i dont know if this is it or not here 436

The remainder should be 2, not 6. Francine mistakenly added 6 instead of 2, leading to the incorrect conclusion. The correct statement is that 86 divided by 4 is 21 with a remainder of 2.

Francine made a mistake in her reasoning. The correct statement would be that 86 divided by 4 is 21 with a remainder of 2, not 20 with a remainder of 6.

Let's analyze her reasoning using the equation she provided:

4x20 + 6 = 86

If we multiply 4 by 20, we get 80, not 86. So, the correct equation should be:

4x20 + 2 = 86

By solving this equation, we find that:

80 + 2 = 86

Hence, the remainder should be 2, not 6. Francine mistakenly added 6 instead of 2, leading to the incorrect conclusion. The correct statement is that 86 divided by 4 is 21 with a remainder of 2.

Answer:

Multiply the first equation by 2 and the second equation by 3 to eliminate y

Step-by-step explanation:

First equation: 4x − 3y = 34

Second equation: 3x + 2y = 17

Multiply the first equation by 2 and the second equation by 3 to eliminate y

2( 4x − 3y = 34 )  = 8x -6y = 68

3( 3x + 2y = 17) = 9x  +6y = 51

Add the equations together

8x -6y = 68

9x  +6y = 51

----------------------

17 x    = 119

The correct answer should be A.

Answer:

x = -9

-8x + -56 = 16

-8x - 56 = 16

-8x = 16 + 56

-8x = 72

x = 72/8

x= -9

Answer:

-9

Step-by-step explanation:

-8x + (-56) = 16

Take away -56 from both sides

-8x = 72

Divide both sides by -8

x = -9

Answer:

[tex]Sea\ of\ Galilee = -690ft[/tex]

Step-by-step explanation:

Given

[tex]Lowest\ Elevation = 23ft[/tex] below sea level

Sea of Galilee = 30 times Lowest in Lammefjord, Denmark

Required

Determine the elevation of the Sea of Galilee

We have that the lowest elevation in Lammefjord is:

[tex]Lowest\ Elevation = -23ft[/tex]

It is negative because, the elevation is below sea level.

Calculating the elevation of Sea of Galilee, we have:

Sea of Galilee = 30 times Lowest in Lammefjord, Denmark

[tex]Sea\ of\ Galilee = 30 * -23ft[/tex]

[tex]Sea\ of\ Galilee = -690ft[/tex]

Hence, the elevation of Sea of Galilee is -690ft or 690ft below sea level
