Answer:
y = -3x^2 -9x +30
Step-by-step explanation:
When a polynomial has a zero at x=p, it has a factor of (x -p). The factors of your quadratic are ...
f(x) = (x +5)(x -2)
At the point x=3, the value of this product is ...
f(3) = (3 +5)(3 -2) = (8)(1) = 8
In order for that value to be -24, it needs to be multiplied by a scale factor of -3. The quadratic you want is ...
y = -3(x +5)(x -2)
y = -3x^2 -9x +30 . . . . . standard form
Answer:
The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same rate. The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.
Step-by-step explanation:
<1=<2
<3+(<1 or <2)=180
6x+y-4=x-9y+1
5x+10y=5
12x-9y=177
Solve for x and y

Answer:
D
Step-by-step explanation:
In an arithmetic sequence, the order must be least to greatest and there must be a consecutive sequence in addition, not any other operation. A is wrong because it is in greatest to least. B is wrong because 0 is the least so all 0's should be at the front instead. C is wrong because each following value is x2.
Answer:
9 7/40
Step-by-step explanation:
3 4/5 + 5 3/8
First we need to get a common denominator of 40
3 4/5 * 8/8 = 3 32/40
5 3/8 *5/5 = 5 15/40
Add the fractions together
3 32/40+ 5 15/40
8 47/40
Rewriting
8 + 40/40 + 7/40
8 + 1+ 7/40
9 7/40
