Represent the numbers as expressions.
number 1 - n
number 2 - n + 9

Isolate “n.”
n + n + 9 = 85
2n + 9 = 85
2n = 85 - 9
n = 76/2
n = 38

Determine the numbers by substituting the n value into the expressions.

1. n = 38
2. n + 9 = 38 + 9 = 47

Therefore the numbers are 38 and 47.

Answer:

38 and 47

Step-by-step explanation:

The first number would be = (85-9)/2

= 76/2 = 38

The second number would be either 85 - 38 or 38 + 9 = 47

Hope this help :3

Answer:

The length of the rectangle is \dfrac{ 1}{3} \text{ feet} .

Step-by-step explanation:

<u>The complete question is:</u> The area of a rectangle is 7/9 square feet. The width of the rectangle is 2 1/3 feet. What is the length of the rectangle?

Let the length of the rectangle be represented as 'L' and the width of the rectangle be represented as 'W'.

As we know that the area of the rectangle is given by;

  Area of rectangle =  Length of rectangle \times Width of rectangle

                                   Or

                       A  =  L \times W

Here, we know the value of A = 7/9 square feet and W = 2 1/3 feet.

SO,        \frac{7}{9} = \text{L} \times 2\frac{1}{3}

             \frac{7}{9} = \text{L} \times \frac{7}{3}

              \text{L} = \frac{7\times 3}{9\times 7}

              \text{L} = \frac{ 1}{3} \text{ feet}

Hence, the length of the rectangle is \frac{ 1}{3} \text{ feet} .

The degree of this polynomial is 3, so it has to have 3 roots or 3 zeros.
If it has one non-repeated x-intercept, that means that this polynomial has ine real zero.
So, it needs 2 more, and this 2 are complex zero.

Correct answer is B. One real and 2 complex zeroes.

Given four functions, which one will have the smallest y-intercept?
Natalka [10]
F(x) function has a starting value of $6.00 and increases from there.So the y-intercept is 6.

g(x) function shows in the table that when x = 0, y = 6. This is the y-intercept.

h(x) shows on the graph that the y-intercept is  4.

j(x) is an exponential growth function, a * b^x where a is the y-intercept.
y = 10^ x^x has a y-intercept at 10. 

The smallest y-intercept is function h(x).
