Answer:
A
Step-by-step explanation:
vertex = (-4, -4)
vertex form:
y = a(x-h)^2 + k
__________
y = (x- (-4))^2 + (-4)
y = (x+4)^2 -4
y = (x+4)(x+4) - 4
y = x^2 + 8x + 16 - 4
y = x^2 + 8x + 12
answer: A

The perimeter of a triangle is 17x−5 units. One side is 3x+5 units and another is 8x−3 units. How many units long is the third side?
Answers
9514 1404 393
Answer:
6x -7 units
Step-by-step explanation:
Let c represent the length of the third side. The perimeter is the sum of the three side lengths.
P = a + b + c
(17x -5) = (3x +5) +(8x -3) +c
17x -5 = 11x +2 + c . . . . . . . . . . . . collect terms
6x -7 = c . . . . . . . . . . . . . . subtract 11x+2
The third side is 6x -7 units.

Which graph represents the solution to the inequality? 4v - 2 < 10
Answers
Answer:
Option C.
Step-by-step explanation:
First, simplify the inequality. Add 2 to both sides:
4v - 2 < 10
4v - 2 + 2 < 10 + 2
4x < 12
Divide both sides by 4:
4x ÷ 4 < 12 ÷ 4
x < 3
As 3 will not satisfy the inequality, it is not a solution. The option that shows x being less than 3 but not including is option C.

Answer:a 750g bag is better.
Step-by-step explanation: 3 bags would be more G the 2kg and less money 0.23/100 grams 700 g would be 1.4$ for that so 750 g is the best.
Answer:
750 grams at $1.39
Step-by-step explanation:
To make it easy to see, determine how much each option costs per gram.
750 grams cost 1.39. Divide 1.39 by 750 which gives you 0.001853
2 kg is 2000 grams costing 3.99. Divide 3.99 by 2000 which give you 0.001995
100 grams cost $0.23. Divide 0.23 by 100 which gives you 0.0023
So the 750 grams is the best price.

3x + y = 3
x - 2y = 4
Answers
Since we have a unique value of x and y, it shows that the system of the equation is consistent and independent.
Given the system of equation expressed as:
3x + y = 3
x - 2y = 4
Solve simultaneosly;
3x + y = 3 ............. 1 * 1
x - 2y = 4 ...............2 * 3
_________________________
3x + y = 3
3x - 6y = 12
Subtract
y-(6y) = 3 - 12
7y = -9
y = -9/7
Substitute y = -9/7 into the equation to get x
x - 2y = 4
x - 2(-9/7) = 4
x + 18/7 = 4
x = 4 - 18/7
x = 3/7
Since we have a unique value of x and y, it shows that the system of the equation is consistent and independent.

Answer:
1) 350
2) 195.83
Step-by-step explanation:
#1.Tuition fee = $12, 000 per year.
30% of it's being paid off by the scholarship, so she'll have to pay:
[tex] = 12000 - ( \frac{30}{100} \times 12000) [/tex]
[tex] = 12000 - 3600[/tex]
[tex] = 8400[/tex]
She'll have to pay $ 8400 by herself, her savings.
If she's saving $ 8400 for two years, she's actually saving $ 8400 for 24 months!
for one month, it'll be
= 8400/ 24
= $ 350 per month
#2one year fee = $ 10, 700
uncle pays half of it, I.e., 10700/ 2
= $ 5, 350
he gets a grant for $ 3,000
so, the part of the fee he ain't paying
= 5,350 + 3000
= $ 8,350
So, he'll have to save:
= 10,700 - 8,350
= $ 2,350
that is per year,
for per month = 2350/ 12
= $ 195.83
