lukranit [14]2 years ago
3 0

Answer:

(-1,4), (-5,0), (3,10) I hope this helps.

What I did I reduced the equation and got y by itself. The new equation would be y=3/2x+11/2x. I started plugging in points. I put the equation on a graph and found those points on the graph.

Solve the inequality<br> 3 + 9x &gt;4(x+7)<br> pls help
alexandr402 [8]

Answer:

x<5

Step-by-step explanation:

the greater sign will firstly be changed to = for better solving so we obtain

3+9x=4(x+7)by opening bracket

3+9x=4x+28

9x-4x=28-3

5x=25

divide all through by 5x

we obtain

x=5

the greater sign change here

which is x<5

What is “ f(x) = 2x^2- 32x” in standard form if it has one?
kap26 [50]
Most textbooks interpret standard form of a quadratic function to be as follows:

f(x) = a x^{2}  + bx + c

In the function f(x) = 2 x^{2}  - 32x , notice we do not have a value for "c". Just place a "0" in for the c and you have standard form.

the criteria for standard form:
1. All like terms are combined
2. Degree must drop from left to right
3. The leading coefficient cannot be equal to zero.

Which of the following is a function?
seropon [69]

Answer:

C

Step-by-step explanation:

For any of the functions described above, the only way any of those could be functions is that there has to be a difference value for each x, unless it is the same x-value. If the x is mentioned twice, that is fine, as long as the y point is also the same. If it is different, it is not a function.

The altitude of a triangle is 2 m longer than its base. What are the dimensions of the altitude and the base if thearea of the t
HACTEHA [7]

Step-by-step explanation:

Let base of triangle be x m.

Therefore, altitude =( x + 2)m

area \: of \:  \triangle =  \frac{1}{2}  \times base \times altitude \\  \\ 40 =  \frac{1}{2}  \times x \times (x + 2) \\  \\ 80 =  {x }^{2} +2x \\  \\   {x}^{2}  + 2x - 80 = 0 \\  {x}^{2}  + 10x - 8x - 80 \\ x(x + 10) - 8(x + 10)  = 0\\ (x + 10)(x - 8) = 0 \\ x + 10 = 0 \:  \: or \:  \: x - 8 = 0 \\ x =  - 10 \:  \: or \:  \: x = 8 \\ base \: can \: not \: be \:  - ve \\ x \neq - 10 \\ x = 8 \\ x + 2 = 8 + 2 = 10 \\

Therefore

Altitude = 10 m

Base = 8 m
