p = 14/4
Answer:
To solve a system of linear equation graphically, it is best to write both equations in slope-intercept form first. After you put them in slope-intercept form, you should be able to graph them easily.For one solution, the two lines have to intersect at exactly one point, since both equations are satisfied at the intersection.
For no solution, the two lines have to never intersect, which means they have to be parallel lines. In other words, no solution will satisfy both equation.
Answer:
The y-coordinate is changing by the rate of -70 cm per sec.
Step-by-step explanation:
Given equation,

Differentiating with respect to time (t),

We have,


Answer: 120 cm².
Step-by-step explanation:
1. To solve this problem you must apply the formula for calculate the area of a triangle, which is:

Where <em>b</em> is the base and <em>h</em> is the height of the triangle.
2. Then, when you substitute the values given in the problem you obtain:

3. You know that the shape is made of 12 right triangle of equal size, therefore, multiply the area obtained by 12.
4. Then the area of the shape is:
