Answer:

We get the value of a: [tex]\mathbf{a<-9}[/tex]

Step-by-step explanation:

We have to solve the inequality [tex]1<\frac{a+7}{-2}[/tex]

So, solving the inequality and finding value of a

First step is to switch both sides and for doing so, the inequality will be reversed

[tex]\frac{a+7}{-2}>1[/tex]

Multiply both sides by -2, as we are multiplying by a negative number, the inequality will be reversed

[tex]\frac{a+7}{-2}\times -2<1\times -2[/tex]

[tex]a+7 < -2[/tex]

Now, subtracting both sides by 7, to find value of a

[tex]a+7-7<-2-7\\a<-9[/tex]

We get the value of a: [tex]\mathbf{a<-9}[/tex]

Step-by-step explanation:

The function f(x)f(x) is a quadratic function and the zeros of f(x)f(x) are 11 and 55. The y-intercept of f(x)f(x) is 2020. Write the equation of the quadratic polynomial in standard form.

Answers

Answer: [tex]4x^2 -24x+20[/tex]

Step-by-step explanation:

If p and q are zeroes of f(x), then f(x) = k (x-p)(x-q) , where k is a constant.

Given: The function f(x)f(x) is a quadratic function and the zeros of f(x)f(x) are 1 and 5.

f(x) = k (x-1)(x-5)

y-intercept = Value of function at x=0

So, y-intercept =  k (0-1)(0-5)= 5k

Since,  y-intercept of f(x) = 20

so, 5k = 20

⇒ k= 4

Quadratic polynomial [tex]= 4(x-1)(x-5)[/tex]

[tex]=4(x^2-6x+5)\\\\= 4x^2 -24x+20[/tex]

Hence, the equation of the quadratic polynomial in standard form =[tex]4x^2 -24x+20[/tex]

i believe it’s (4,22)
i’m sorry if that’s not correct
have a great day!:)

Answer:

(4, 22)

Step-by-step explanation:

y = 5x + 2

y  = 3x + 10

Since both equations are equal to y, we can have both equations equal to each other).

5x + 2 = 3x + 10

5x + 2 - 3x - 2 = 3x + 10 - 3x - 2

5x - 3x = 10 - 2

2x = 8

2x/2 = 8/2

x = 4

(Substitute the x value to any equation to solve for y).

y = 5x + 2

y = 5(4) + 2

y = 20 + 2

y = 22

So, the answer is (4, 22).

Justin has a roll of tape 549 centimeters long. he cuts the tape into pieces that are 9 centimeters long. How many 9 centmeter pieces can Justin cut from his roll of tape?

Answers

Answer: 61

Step-by-step explanation: My Teacher told me is Right

The number of the 9-centimeter long tape will be 61. The correct option is C.

What is division?

Discovering the maximum number of equal pieces that can be made by splitting an integer into equal parts.

One of the four fundamental arithmetic operations, or how numbers are combined to create new numbers, is division. The other operations are multiplication, addition, and subtraction.

Given that Justin has a roll of tape 549 centimeters long. he cuts the tape into pieces that are 9 centimeters long.

The number of 9 centimeters tapes will be calculated as below:-

Number = 549 / 9

Number = 61

Therefore, the number of the 9-centimeter long tape will be 61. The correct option is C.
