The sum of two numbers is 62 and their difference is 16.Which system of equations represents the word problem? x + y = 62 and x - y = 16 x + y = 62 and 62-x = 16 x + 62 = y and x - 16 = y

Which function has real zeros at x = −10 and x = −6?A. f(x) = x2 + 16x + 60
B. f(x) = x2 − 16x + 60
C. f(x) = x2 + 4x + 60
D. f(x) = x2 − 4x + 60

Answers

Answer:

Option (a) is correct.

$f(x)=x^2+16x+60$

Step-by-step explanation:

Given :A function has real zeros at x = −10 and x = −6 .

We have to find the function that has real zeros at x = −10 and x = −6.

Consider real zeros at x = −10 and x = −6.

x = - 10 ⇒ x + 10 = 0

x = - 6 ⇒ x + 6 = 0

Multiply both zeroes, we have,

$(x+10)(x+6)$

Apply Distributive rule,

$(a+b)(c+d)=ac+ad+bc+bd$

we have,

$(x+10)(x+6)=x^2+10x+6x+60$

Simplify, we have,

$(x+10)(x+6)=x^2+16x+60$

Thus, $f(x)=x^2+16x+60$

Option (a) is correct.

At Elisa's printing company llc there are two kinds of printing presses: model a which can print 70 books per day and model b which witch can print 55 books per day. Company owns 14 total Printing Presse sand this allows 905 books per day. How many of each type of press do they have..

Answers

a (70 books/day) A=number of model A
b (55 books/day) B =number of B , A=number of a then
A+B =14 ........ A=14-B
aA+bB =905
70(14-B) +55B =905
980-70B+55B=905
-15B=-75
B=-75/-15 =5
A=14-B=14-5=9

Elisa's Printing Company has 9 Model A printing pressesand 5 Model B printing presses.

Given that Elisha's printing company have two kinds of printing presses,

Model A = 70 books per day

Model B = 55 books per day

In total they have printing presses, which allows 905 books per day.

We need to find number of each of press,

Let's assume Elisa's Printing Company has x Model A printing presses and y Model B printing presses.

According to the given information, the total number of Model A printing presses (x) can print 70x books per day, and the total number of Model B printing presses (y) can print 55y books per day. Since the company owns 14 total printing presses, we can create the following equation:

x + y = 14 (Equation 1)

The total number of books printed per day is given as 905. So, we can set up another equation based on the printing capacities of each model:

70x + 55y = 905 (Equation 2)

Now, we can solve these equations simultaneously to find the values of x and y.

Multiplying Equation 1 by 70, we get:

70x + 70y = 980 (Equation 3)

Subtracting Equation 2 from Equation 3:

(70x + 70y) - (70x + 55y) = 980 - 905

Simplifying:

15y = 75

Dividing both sides by 15:

y = 5

Substituting the value of y in Equation 1:

x + 5 = 14

x = 14 - 5

x = 9

Therefore, Elisa's Printing Company has 9 Model A printing pressesand 5 Model B printing presses.

Nine more than thirty divided by ten

Answers

3.9

9 more than so 9+30 so 39÷10 so 3.9

Step-by-step explanation:

Nine more than thirty divided by ten

This is not algebra but a simple expression, but written like this it has 2 interpretations, so in mathematics numbers and signs are used instead of words, the two expressions could be 9 + 30 : 10 = or (9 + 30) : 10 =

9 + 30 : 10 = (remember PEMDAS)

9 + 3 =

(9 + 30) : 10 =

39 : 10 =

39/10 or 3.9
