Answer:

C and D

Step-by-step explanation:

We can see that the base of the bigger triangle is 6. Based on the straight sides adjacent to the hypotenuse, the bigger one's height is 6 and the smaller one's is 3. This means that the smaller one is half the size of the bigger one. This means that if the bigger base is 6, the smaller one is 3. Since it is 3, we move 3 spaces left from point Z to get point Y. If you moved 3 spaces left, it would be (-5,2). You can also move 3 spaces right and then your Y point would be at (1,2) so C and D are the 2 possible answers.

Write a polynomial FOR A third-degree polynomial with leading coefficient -4

umka2103 [35]

Answer:

$-4x^3 + 2x^2-3$

Step-by-step explanation:

Degree is the highest exponent on the variable in a polynomial.

A leading coefficient is the first terms coefficient when the polynomial is written in standard form.

To write this polynomial, write $-4x^3$ as your first term. Its leading coefficient is -4 and it has a degree of 3. Then add whatever terms after it being sure to not add any more with exponent 3 or higher.

Example: $-4x^3 + 2x^2-3$

How many intersections are there of the graphs of the equations below?

kipiarov [429]

Answer:

The number of intersections = ∞

Step-by-step explanation:

Given the system of equations:

0.5 x + 5y = 6

3x + 30y = 36

By multiplying the first equation by 6

∴ 6 (0.5 x + 5y) = 6 * 6

∴ 3x + 30y = 36

So, Those equations are "Dependent", because they are really the same equation, just multiplied the first equation by 6.

So, the two equations are identical

Therefore: They have infinity number of solutions.

See the attached figure.

0.5 x + 5y = 6 ⇒ in black color

3x + 30y = 36 ⇒ in red color
