Given y = x^2 - 4, what is the value of y when x = -5?​

Answers

Answer 1

Answer:

21

Step-by-step explanation:

y = [tex]x^{2}[/tex] -4  Substitute in -5 for x

y = [tex](5)^{2}[/tex] - 4

y = 25 - 4

y = 21

Answer 2

Answer:

y = 21

Step-by-step explanation:

Plug in -5 into the equation

(-5)² - 4
25 - 4 = 21

A programme declares a variable whenever it states that it requires one. Place declaration statements for our brief programmes in-between the main method's two curly braces. The variable's name and data type are provided in the declaration. It could also provide a specific value that has to be entered into the variable.

When a variable is given a value for the first time, it is said to be initialized. The symbol = stands in for the assignment operator. Instead of writing int I and then 9, you can establish a variable for addition and then give it a value in the same line by writing int I = 9.

Gabriel started training with the track team five weeks ago. During the first week, he ran 0.5 mile at each practice. The next three weeks he ran 0.75 mile, 1 mile, and 1.25 miles at each practice. If he continues this pattern, how many miles will he be running at each practice during the 7 th week?

Answers

If Gabriel continues the pattern of running that he has done on the past four weeks, the miles he will run on the 7th week is 2 miles.

How many miles will Gabriel run?

Gabriel's pattern of running is such that he increases the number of miles by 0.25 miles every week.

This is why he ran 0.5 miles, and then 0.75 miles and then 1 mile.

If he keeps going like this, one the 7th week, he will run:

5th week = 1.5 miles

6th week = 1.75 miles

0.125 gallons of the 35% acid solution Eli should add.

Step-by-step explanation:

Given: Eli wants to combine 0.5 gallon of a 10% acid solution with some 35% acid solution to make a 15% acid solution.

To find: Equation can you use to determine how many gallons of the 35% acid solution Eli should add?

Solution:

Let x be the gallons of the 35% acid solution.

According to question,

For 0.5 gallon of a 10% acid solution = 0.5×0.1

For x gallon of a 35% acid solution = x×0.35

For (0.5+x) gallon of a 15% acid solution = 0.5 + x × 0.15

The equation form is

0.5 gal × (0.1) + x gal × (0.35) = (0.5+x) × (0.15)

Solving the above equation,

0.05 + 0.35x = 0.075 + 0.15x

0.2x = 0.025

x = 0.025/0.2

x= 0.125

Therefore, 0.125 gallons of the 35% acid solution Eli should add.

Therefore, 0.125 gallons of the 35% acid solution Eli should add.The equation is 0.5 gal × (0.1) + x gal × (0.35) = (0.5 + x) × (0.15)

Which inequality represents this situation?

Answers

Answer:

5s + 3.50d < 40

Step-by-step explanation:

if you were to total up the costs of a snack and drink together you'll end up with $8.50

-multiply $8.50 until you reach $40 mark

i.e 8.50×2(means 2 of each item) = $17

8.50×3 = $25.5

8.50×4 = $34

8.50×5= $42.5

-if you look at it, the calculation for 5, the pricing is now over the budget therefore the answer is then 5s + 3.50d < 40 because she can only spend up to $34 at most

What is an integer?

The collection of positive and negative integers is known as an integer. Integers, like whole numbers, do not include the fractional portion. Integers can therefore be defined as numbers that can be positive, negative, or zero but not as fractions. On integers, we can carry out all arithmetic operations, including addition, subtraction, multiplication, and division. Integer examples include 1, 2, 5, 8, -9, -12, etc. "Z" stands for an integer. The Latin term "Integer," which implies entire or intact, is where the word "integer" first appeared. Zero, positive numbers, and negative numbers make up the particular set of numbers known as integers.

Integer examples include: -1, -12, 6, and 15.

Zero is not an integer that can be positive or negative. There is no (+ or -) sign on zero, making it a neutral number.

F(2) = 3

We learn that for the majority of the graphs by examining different graphs.

The domain and range of the given function are: domain: {-7,-3,-2,2,4,6} range: {-3,0,1,2,3,6}. (Option A).

What is domain and range?The terms Domain and Range describe the input values and the function's output values, respectively.In terms of coordinates, domain is the x-coordinate and range is the y-coordinate of a function.

Now,

In the given function {(-3,4),(0,6),(2,-2),(1,-3),(6,-7),(3,2)},

the x- coordinates are: {-3, 0, 2, 1, 6, 3} and the y-coordinates are: {4, 6, -2, -3, -7, 2}.

Thus, According to the definition of domain and range,

the domain is {-3, 0, 2, 1, 6, 3} and the range is {4, 6, -2, -3, -7, 2}.

Hence, Option A is correct, i.e., the domain and range of the given function are: domain: {-7,-3,-2,2,4,6} range: {-3,0,1,2,3,6}.

Is this how you solve this (finding the inverse)

Answers

There are a couple ways to go about this.

By definition of inverse function, if [tex]j^{-1}[/tex] exists, then

[tex]j\left(j^{-1}(x)\right) = x[/tex]

All this means is that if you provide some input [tex]x[/tex], plug it into [tex]j^{-1}(x)[/tex], then plug that into [tex]j(x)[/tex], you end up recovering the original input [tex]x[/tex] that you started with.

We can also do this in the opposite direction, so

[tex]j^{-1}(j(x)) = x[/tex]

So now if [tex]j(x)[/tex] is invertible, then

[tex]j(x) = -\dfrac23 x - 9 \implies j\left(j^{-1}(x)\right) = -\dfrac23 j^{-1}(x) - 9 = x[/tex]

Solve for [tex]j^{-1}[/tex].

[tex]-\dfrac23 j^{-1}(x) - 9 = x[/tex]

[tex]\dfrac23 j^{-1}(x) = -x - 9[/tex]

[tex]j^{-1}(x) = -\dfrac32 (x+9)[/tex]

[tex]\boxed{j^{-1}(x) = -\dfrac32 x - \dfrac{27}2}[/tex]

Another way to do it is by algebraically substituting [tex]x[/tex] within the definition of [tex]j(x)[/tex]

Starting with the given definition

[tex]j(x) = -\dfrac23 x - 9[/tex]

we replace [tex]x[/tex] with some new expression in a new variable [tex]y[/tex] that makes the right side reduce to just [tex]y[/tex]. To demonstrate, if we multiply [tex]-\frac23 x[/tex] by [tex]-\frac32[/tex], we end up with a coefficient of 1. So let [tex]x=-\frac32 y[/tex]. Then

[tex]j\left(-\dfrac32 y\right) = -\dfrac23 \left(-\dfrac32 y\right) - 9 = y - 9[/tex]

As you can see, this doesn't completely reduce to [tex]y[/tex], so we're not done. To adjust for this, we just add 9 to [tex]y[/tex], so our ultimate substitution is [tex]x=-\frac32(y+9)[/tex]. Then

[tex]j\left(-\dfrac32 (y+9)\right) = -\dfrac23 \left(-\dfrac32 (y+9)\right) - 9 = (y+9) - 9 = y[/tex]

Now applying [tex]j^{-1}[/tex] to both sides,

[tex]j^{-1}\left(j\left(-\dfrac32 (y+9)\right)\right) = j^{-1}(y)[/tex]

[tex]\implies \boxed{j^{-1}(y) = -\dfrac32 y - \dfrac{27}2}[/tex]

(we can freely swap out [tex]y[/tex] for [tex]x[/tex] at this point)

Yet another way, since the function here is quite simple, we can just think about the action of [tex]j[/tex] on a given number [tex]x[/tex] - multiply it by -2/3, and subtract 9.

[tex]x \mapsto -\dfrac23 x \mapsto -\dfrac23x - 9 = j(x)[/tex]

The inverse operation undoes this, so given some number [tex]j(x)[/tex], we recover [tex]x[/tex] by adding the additive inverse of -9, or 9, then multiplying the whole result by the multiplicative inverse of -2/3, or -3/2.

[tex]j(x) \mapsto j(x) + 9 \mapsto -\dfrac32(j(x) + 9) \mapsto -\dfrac32 j(x) - \dfrac{27}2 = x[/tex]

You seem to be using some version of this method. You made the mistake of thinking the "multiply by -3/2" step applies only to [tex]j(x)[/tex], and not [tex]j(x) + 9[/tex].
