Answer:

x=11

Step-by-step explanation:

7x-9=28+4(x-1)

7x-9=28+4x-4

7x-9=24+4x

7x-9-4x=24

3x-9=24

3x=24+9

3x=33

x=33/3

x=11

Answer:

B

Step-by-step explanation:

if a number (lets say 'y' is that number) is equal to (I.e. y = )..mathematically

now y is equal to twice the smaller number ( lets say that the smaller number is 'x' ) plus (+) 3 . that brings us to the linear equation...

y = 2x + 3;

also the second part of the question says that the same number ( I.e. 'y' here ) is twice the sum of smaller number (I.e. '2x' here ) and 1.

which gives us 2nd equation I.e.

y = 2x + 1 ;

the question is to find the possible number of solutions for both these equation

to find solution means to find all those points or say numbers which would satisfy both these equations

now for the first equation..

lets say ( y = 5 ) this means ( 2(1) + 3 )

so the solution will be ( 1, 5)

now for the second equation..

we will proceed with whatever data we know..

I.e. we know that value of ' y ' is 5, as we assumed

putting value of y in 2 nd equation we get ( 2(2)+1 )

I.e solution will be ( 2, 5)

now what does this signify...?

it signifies that there is no such point that will satisfy both these equations simultaneously..

hence we can say that there is no solution possible to this situation.

Answer:15.5

Step-by-step explanation:

Answer:

15.5 feet

Step-by-step explanation:

To work out the perimeter of any shape, you need to add the lengths of all the sides together for the total perimeter.

4.5 + 6.4 + 4.6 = 15.5 ft

60 pounds of sausage and 80 pounds of bacon are not solution of inequality. Therefore, option C is the correct answer.

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Given that, the inequality 5x+4y≤500 represents the possible combinations of pounds of sausage (x) and bacon (y) you can buy.

The inequality reduced to y≤-5/4x+125

A) 20 pounds of sausage and 90 pounds of bacon

90≤-5/4×20+125

90≤100

B) 40 pounds of sausage and 40 pounds of bacon

40≤-5/4×40+125

40≤75

C) 60 pounds of sausage and 80 pounds of bacon

80≤-5/4×60+125

80≤50

Does not represent the solution of equation.

D) 80 pounds of sausage and 20 pounds of bacon

20≤-5/4×80+125

20≤25

Therefore, option C is the correct answer.

Answer:

[tex]\frac{10}{3}[/tex]  

I hope this helps!

Answer:

The answer is m= 2.4r.

The equation that represents and reflects the relationship between x and y is [tex]\mathbf{y =2.4x}[/tex]

Let y represents the amount they collect, and x represents the number of raffle tickets they sell.

So, the ratio is represented as:

[tex]\mathbf{y : x =24 : 10}[/tex]

Express the ratio as fractions

[tex]\mathbf{\frac{y }{ x} =\frac{24 }{ 10}}[/tex]

Divide 24 by 10

[tex]\mathbf{\frac{y }{ x} =2.4}[/tex]

Multiply both sides by x

[tex]\mathbf{y =2.4x}[/tex]

So, the equation that represents and reflects the relationship between x and y is [tex]\mathbf{y =2.4x}[/tex]

See attachment for the graph of [tex]\mathbf{y =2.4x}[/tex]

Answer:

[tex]d=\frac{3}{2}=1.5[/tex]

Step-by-step explanation:

We have the function:

[tex]y=a(x-2)(x-1)[/tex]

And we want to find x=d for which the minimum/maximum value will occur.

Notice that our function is a quadratic in factored form.

Remember that the minimum/maximum value always occurs at the vertex point.

And remember that the x-coordinate of the vertex is the axis of symmetry.

Since a quadratic is always symmetrical on both sides of its axis of symmetry, a quadratic’s axis of symmetry is the average of the two roots/zeros of the quadratic.

Therefore, the value x=d such that it produces the minimum/maximum value is the average of the two roots.

Our factors are (x-2) and (x-1).

Therefore, our roots/zeros are x=1, 2.

So, the average of them are:

[tex]d=\frac{1+2}{2}=3/2=1.5[/tex]

Therefore, regardless of the value of a, the minimum/maximum value will occur at x=d=1.5.

Alternative Method:

Of course, we can also expand to confirm our answer. So:

[tex]y=a(x^2-2x-x+2)\\y=a(x^2-3x+2)\\y=ax^2-3ax+2a[/tex]

The x-coordinate of the vertex is still going to be the place where the minimum/maximum is going to occur.

And the formula for the vertex is:

[tex]x=-\frac{b}{2a}[/tex]

So, we will substitute -3a for b and a for a. This yields:

[tex]x=-\frac{-3a}{2a}=\frac{3}{2}=1.5[/tex]

Confirming our answer.
