Answer: x ≥ 5

Step-by-step explanation:

7 is increased by the product of a number and 3: 7 + 3x

Is at least 22: ≥ 22

Your equation is: 7 + 3x ≥ 22

subtract 7 from both sides

3x ≥ 15

divide both sides by 3

x ≥ 5

2x + 7y + 3x - 4y

Collect all the like terms:

2x + 3x = 5x

7y - 4y = 3y

And you end up with 5x + 3y as your final answer :)

The perimeter of a rectangle is 100 yd. if its width is four times its length, what is the area?

7nadin3 [17]

Length = l

Width = w

Perimeter = p = 100

Perimeter of rectangle = 2(l+w)

100 = 2 (4w + w)

100 = 2(5w)

100 = 10w

100/10 = w

10 = w

w = 10

Area of rectangle = length * width

a = l*w

a = 4w*w

a = 4w^2............(1)

Put the value of w in (1)

a = 4(10)^2

a= 4(100)

a = 400 yd^2

15. Construct the slope-intercept form equation of the line passing through (-5,23) and (10,-5).

Radda [10]

Answer:

15y = -28 x + 205.

Step-by-step explanation:

Slope intercept form of equation is y = mx + c where m is slope and c is the y intercept.

Now slope of line passing through points (-5, 23) and (10, -5):

$m = \frac{y_{2} - y_{1} }{x_{2} - x_{1} } = \frac{-5 -23}{10 + 5} = \frac{-28}{15}$

Now equation of line:

y = mx + c

substituting the value of m in above expression,

$y = -\frac{28}{15} x + c$

Now, since the line is passing through the point (-5, 23) therefore, x = -5 and y = 23. By substituting these values in above equation,

$23 = -\frac{28}{15} \times (-5) + c$

$23 = \frac{28}{3} + c$

$c = 23 - \frac{28}{3} = \frac{69 - 28}{3} = \frac{41}{3}$

So equation of line in slope intercept form:

$y = -\frac{28}{15} x + \frac{41}{3}$

Further solving,

15y = -28 x + 205.
