Option A
Step-by-step explanation:
Option A
f(x) = -3(x + 7)(x + 4),
Remember that to solve for the x-intercepts we equate y to 0,
-3(x + 7)(x + 4) = 0
Using the zero product property,
x + 7 = 0, x + 4 = 0
x = - 7, x = -4
x -intercepts: (- 7, 0) & (- 4, 0)
Hence proved.

If f(x) = 2 (3x) + 1 , what is the value of f(2) ?
Answers
Answer:
13
Step-by-step explanation:
f(x)=2(3x)+1
f(2)=2(3X2)+1
f(2)=2(6)+1
f(2)=12+1
f(2)=13
The value of function f(2) is 13.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
Given function; f(x) = 2 (3x) + 1
We need to find the value of f(2) .
f(x) = 2(3x)+1
f(2) = 2(3 * 2)+1
f(2) = 2(6)+1
f(2)=12+1
f(2)=13
Therefore, the value of function f(2) is 13.

estimate a 15% on a dinner bill of $42.58 by first rounding the bill amount to the nearest ten dollars
Answers
Answer:
$6
Step-by-step explanation:
Round $42.58 to the nearest ten dollars to get $40. $40 ÷ 100 = $0.4 so this is one percent. $0.4 × 15 is $6 which is an estimate of 15% of $42.58.
The answer is $6 (unless if you are meant to add this to $42.58 - then the answer would be $48.58 - but I am not sure because of the wording of the question).

Solve for p in 2.5+3(5 – 2.1p) = -13.37
Answers
Answer: p = 4.9
Step-by-step explanation:
2,5 + 3(5-2.1p) = -13,37
2,5 + 3(5-2.1p) - 2,5 = -13,37 - 2,5
3(5-2.1p) = -15,87
3(5-2.1p) / 3= -15,87 /3
5-2.1p = -5.9
5+5.29 = 2.1p
(5+5.29 ) /2.1 = 2.1p /2.1

In a high school stadium there are 1575 seats. There are two and a half times as many seats in the home section as there are in the visitor section. Which system of equations could be used to determine the number of seats in the home section, h, and the number of seats in the visitor section, v, in the stadium?
Answers
Answer:
h = 1,125
v = 450
Step-by-step explanation:
Total number of seats = 1575
h = number of seats in the home section
v = number of seats in the visitor section
There are two and a half times as many seats in the home section as there are in the visitor section.
h = 2 1/2 * v
h = 2 1/2v
Total = h + v
1575 = 2 1/2v + v
1575 = 3 1/2v
1575 = 7/2v
v = 1575 ÷ 7/2
= 1575 × 2/7
= (1575*2) / 7
= 3150 / 7
= 450
v = 450
h = 2 1/2v
= 5/2*450
= 2250/2
= 1,125
h = 1,125

400miles uses15g what about 6g.
Using cross multiplication. Multiply 6x400/15 = 160miles
Answer:
160 miles
Step-by-step explanation:
If it travels 400 miles on 15 gallons, then it will travel x miles on 6 gallons
400 miles -> 15 gallons
x miles -> 6 gallons
15 * x = 6 * 400
15x = 2400
x = 2400 / 15
x = 160 miles

Answer:
-17√2 /26 or -0.9247 to the nearest ten thousandth.
Step-by-step explanation:
The hypotenuse of the right triangle in which tan x = 2/3 is √(2^2 + 3^2)
= √13 so sin x = 2/√13 and cos x = 3/√13
sin2x = 2sinxcos
= 2* 2/√13 * 3/√13
= 12/13.
cos2x = cos^2x - sin^2x
= 9/13 - 4/13
= 5/13.
sin(2x + 5π/4)
= sin2x cos5π/4 + cos2x sin5π/4
= 12/13 * -1/√2 + 5/13 * -1/√2
= -12 / 13√2 - 5 / 13√2
= -17/13√2
= -17√2 /26.

What is linear inequality?Linear inequality refers to the relation between a linear algebraic expression to some known value that contains inequality sign.
Unlike a linear equation it can have a range of values inside an interval.
The given inequality can be solved as follows,
4x - 5 ≥ 7
Subtract 7 from both sides to obtain,
4x - 5 - 7 ≥ 0
=> 4x - 12 ≥ 0
