Algebra 1 question 4.
Brrunno [24]

Greetings!

To start this problem, let's first assign a variable for the missing, consecutive odd numbers. Since they are consecutive and odd, we add two.

<u>Proof:</u> <em>3-1=2, 5-3=2</em>

The first, consecutive, odd number: x

The second, consecutive, odd number: x+2

The third, consecutive, odd number: x+4

The fourth, consecutive, odd number: x+6

The sum of the values are equal to 3 times the sum of the first two numbers, of which this is equal to 35 less than the fourth number. Let's create an equation to simplify this:

3((x)+(x+2))=(x+6)-35

Complete the operations inside the parenthesis:

3(2x+2)=(x+6)-35

Distribute the parenthesis (utilizing the distributive property)

(((2x)(3))+((2)(3)))=(x+6)-35

(6x+6)=(x+6)-35

Simplify both sides:

6x+6=x-29

Add -6 and -x to both sides of the equation:

(6x+6)+(-6)+(-x)=(x-29)+(-6)+(-x)

5x=-35

Divide both sides of the equation by 5:

\frac{5x}{5}=\frac{-35}{5}

x=-7

If x is equal to -7:

x+2=-5

x+4=-3

x+6=-1

The four numbers are:

\boxed{-7,-5,-3,-1}

I hope this helps!

Jaqueline used 2.5 pounds of ground beef to make 25 tacos for a family gathering. Peter wants to use the same recipe using 1 pou
enot [183]

Answer:

Peter can make 10 tacos.

Step-by-step explanation:

Jaqueline's recipe calls for .1 pounds of beef per taco.

Given only 1 pound, multiply by, taking the reciprocal of .1 gives us 10 tacos.

f(x)=x2+5x-4 has a domain D={-4,-2,0,3,5} find the range (f(x)) value for each x value in the domain
True [87]

Answer:

The range here is the set {8, -10, -4, 20, 32}.

Step-by-step explanation:

Please use " ^ " to denote exponentiation.  Thanks.   f(x)=x^2 + 5x - 4

f(-4)=(-4)^2 + 5(-4) - 4  =  8

f(-2)=(-2)^2 + 5(-1) - 4   = -10

f(0)=0^2 + 5(0) - 4 = -4

f(3) =3^2 + 5(3) - 4      =   20

f(4)=4^2 + 5(4) - 4       = 32

In this problem we have to calculate the actual function values for the given domain (input values).  The range here is the set {8, -10, -4, 20, 32}.
