X=2 And x+3^2 I do not understand

Answer:

If the discriminant of the quadratic equation is zero then it will have 2 equal roots.

If the discriminant of the quadratic equation is greater than zero then it will have 2 different roots.

If the discriminant of the quadratic equation is less than zero then it will have no roots.

Answer:. 30 : 48

40:64

Step-by-step explanation: The hint is in the table where the rows highlighted in pink, multiples of 5 and 8, contain the values of the original given ratio, 10:16

Equivalent ratios include any of the corresponding values in columns AND that are in the pink rows.

5:8, 10:16, 15:24, 20:32 . . .

We can see the pattern; pairs of multiples of the factors of the numbers in the original ratio are equivalent ratios.

Answer:

0.57575757 / 1

Step-by-step explanation: :)

Answer:

0.5757=19/33

Explanation:

Let x=0.5757

100x=57.5757

100x−x=57.5757−0.5757=57

99x=57

x=57/99=19/33

Inequalities help us to compare two unequal expressions. The correct option is D.

Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.

The two of the given inequalities can be solved as shown below.

2x + 6 < 10

Subtract 6 from both sides of the equation,

2x + 6 - 6 < 10 - 6

2x < 4

Divide both the sides of the equation by 2,

2x/2 < 4/2

x < 2

2x + 8 > 20

Subtract 8 from both sides of the equation,

2x + 8 - 8 > 20 - 8

2x > 12

Divide both the sides of the equation by 2,

2x/2 > 12/2

x > 6

Hence, the correct option is D.

Step-by-step explanation:

Y-3 = -2(x+5)

Rewrite in slope intercept form:

y-3 = -2(x+5)

Simplify the right side:

y-3 = -2x -10

Add 3 to both sides:

y = -2x -7

The y intercept is -7

Step-by-step explanation:

Answer:

[tex](s.t)(x) = 4x^2+24x^2\\(s-t)(x) = x+6-4x^2\\(s+t)(-3) = 39[/tex]

Step-by-step explanation:

Given functions are:

[tex]s(x)= x+6\\t(x)= 4x^2[/tex]

We have to find:

(s.t)(x) => this means we have to multiply the two functions to get the result.

So,

[tex](s.t)(x) = s(x)*t(x)\\= (x+6)(4x^2)\\=4x^2.x+4x^2.6\\=4x^3+24x^2[/tex]

Also we have to find

(s-t)(x) => we have to subtract function t from function s

[tex](s-t)(x) = s(x) - t(x)\\= (x+6) - (4x^2)\\=x+6-4x^2[/tex]

Also we have to find,

(s+t)(-3) => first we have to find sum of both functions and then put -3 in place of x

[tex](s+t)(x) = s(x)+t(x)\\= x+6+4x^2[/tex]

Putting x = -3

[tex]= -3+6+4(-3)^2\\=-3+6+4(9)\\=3+36\\=39[/tex]

Hence,

[tex](s.t)(x) = 4x^2+24x^2\\(s-t)(x) = x+6-4x^2\\(s+t)(-3) = 39[/tex]

Answer:

7 cookies are left out, If Amanda packs 11 boxes of cookies.

Step-by-step explanation:

Amanda has to pack cookies in boxes. The function describes how many cookies she puts in a certain number of boxes:

[tex]c=-6b+ 73[/tex]

here variable c represents number of cookies and variable b represents the number of boxes packed.

We need to find If she packs 11 boxes, how many cookies are left out.

We are given:

b = 11

We need to find c

Putting value of b and finding value of c in the equation.

[tex]c=-6b+ 73\\c=-6(11)+73\\c=-66+73\\c=7[/tex]

So, we get the value of c: c=7

Therefore,  7 cookies are left out, If Amanda packs 11 boxes of cookies.
