Answer:

The required expression is 7n²+89n+60

Step-by-step explanation

To get the expression, we will multiply the two linear expression by opening the bracket to give a quadratic equation.

(n + 12) x (5+7n)

We will use the variable and the constant of n + 12 to multiply that of 5+7n to give;

(n + 12)(5+7n) = 5n + 7n² + 60 + 84n

Rearranging the equation gotten we will have;

7n²+84n+5n+60

= 7n²+89n+60 which is the required quadratic expression.

d1i1m1o1n [39]

Answer:

The following points are not arranged in a parallelogram or rectangle order.

Step-by-step explanation:

Well first we need to graph the following.

A(1,1) B(2,2) C(3,3) D(4,4)

By looking at the image below we can tell it is not any shape, it’s not a parallelogram or a rectangle.

It is a line with a slope of 1 or x.

A contractor has at most $42 to spend on nails for a project. Finishing nails cost $0.45 per pound and common nails cost $0.60 p

mojhsa [17]

Question:

A contractor has at most $42 to spend on nails for a project. Finishing nails cost $0.45 per pound and common nails cost $0.60 per pound. He would like to purchase at least 30 pounds of nails total. Write a system of linear inequalities

Answer:

The system of linear inequalities are:

$x + y\geq 30\\\\0.45x+0.60y\leq 42$

Solution:

Let "x" be the pounds of finishing nails

Let "y" be the pounds of common nails

Given that,

He would like to purchase at least 30 pounds of nails total.

"at least" means that he can purchase 30 pounds or more than 30 pounds also

So, we have to use "greater than or equal to" symbol

$x + y\geq 30$

From given,

Cost of 1 pound of finishing nail = $ 0.45

Cost of 1 pound of common nail = $ 0.60

A contractor has at most $42 to spend on nails for a project

"at most" means he can spend 42 or less than 42

So we have to use " less than or equal to" symbol

Thus we frame a inequality as:

$x \times 0.45 + y \times 0.60\leq 42\\\\0.45x + 0.60y\leq 42$

Thus the system of inequalities are:

$x + y\geq 30\\\\0.45x+0.60y\leq 42$

A can of peas weighs 10 oz. Explain how you would make a graph to model the total weight of peas in terms of the number of cans

Vika [28.1K]

Ur x axis will be the number of cans and ur y axis will be the weight in oz

u will label ur x axis( the number of cans) in intervals of 1......from 0 to 4
u will label ur y axis (the weight) in intervals of 10....from 0 to 40

ur equation would be : y = 10x
points on this line are : (0,0), (1,10), (2,20), (3,30), (4,40)

The graph of the function f(x) = (x − 3)(x + 1) is shown. On a coordinate plane, a parabola opens up. It goes through (negative

mote1985 [20]

Answer:

Correct option: first one -> all real values of x where x < −1

Step-by-step explanation:

First we need to find the roots of the function f(x):

0 = (x - 3)(x + 1)

(x - 3) = 0 -> x = 3

(x + 1) = 0 -> x = -1

The roots of the function are x = 3 and x = -1.

The vertex is between the roots (x = 1) and has a negative value of y (y = -4), so the concavity of the parabola is upwards.

So the graph is decreasing until it reaches the vertex, then the graph is increasing.

Then, we can affirm that the graph is positive and decreasing for all real values of x where x < -1 (for x > -1 and x < 3 we have negative values)

Correct option: first one
