Evaluate: f(-3) =
Answer:
f(-3) = 0
Step-by-step explanation:
The question is asking you to evaluate the function when x = -3. Therefore, substitute -3 in for x and simplify.
f(x) = x² + 7x + 12 <---- Original equation
f(-3) = (-3)² + 7(-3) + 12 <---- Substitute -3 for x
f(-3) = 9 + 7(-3) + 12 <---- Square -3
f(-3) = 9 - 21 + 12 <---- Multiply 7 x -3
f(-3) = 0 <---- Combine terms

Solve the system of equations by substitution.
Given equations:
x + y = 15 . . . . . . . . (1)y = 4x . . . . . . . . . . . (2)To find :
value of xvalue of yPut value of y of second equation (i.e y = 4x) in equation one (i.e x + y = 15)
➞ x + y = 15
➞ x + 4x = 15
➞ 5x = 15
Divide both LHS and RHS by 5
➞ (5x)/5 = 15/5
➞ x/1 = 3/1
➞ x = 3
Now put value of x in equation 2
{Note : value of x can be inserted both in equation 1 and 2}
➞ y = 4x
➞ y = 4 × 3
➞y = 12
Verification :
put value of x and y in equation 1 :
x + y = 1512 + 3 = 1515 = 15LHS = RHS
hence verified !
put value of x and y in equation 2 :
y = 4x12 = 4 × 312 = 12LHS = RHS
hence verified !
∴ Value of x and y is 3 and 12 respectedly .
REQUIRED ANSWER :
(x , y) = (3 , 12)
Answer:
(3, 12)
Step-by-step explanation:
Given equations:
Equation 1: x + y = 15Equation 2: y = 4xSubstitute Equation 2 into Equation 1 and solve for x:
⇒ x + 4x = 15
⇒ 5x = 15
⇒ x = 15 ÷ 5
⇒ x = 3
Substitute the found value of x into Equation 2 and solve for y:
⇒ y = 4(3)
⇒ y = 12
Therefore, the solution of the system is (3, 12)

o 7 days
o 8 days
56 days
o 128 days
Answer:
56 days
Explanation:
[tex]\sf Half \ Life : A = A_O \ x \ (\dfrac{1}{2} )^{\dfrac{t}{h} }[/tex]
where A is final amount, Ao is initial amount, t is time taken, h is half life
Here given:
initial amount: 400 millicuries
final amount: 3.125 millicuries
half life: 8 days
time taken: ?
Hence solve for time taken:
[tex]\sf \rightarrow A = A_O \ x \ (\dfrac{1}{2} )^{\dfrac{t}{h} }[/tex]
insert values given
[tex]\sf \rightarrow 3.125 = 400 \ x \ (\dfrac{1}{2} )^{\dfrac{t}{8} }[/tex]
divide both sides by 400
[tex]\sf \rightarrow (\dfrac{1}{2})^{\dfrac{t}{8}}=0.0078125[/tex]
apply exponent rule
[tex]\sf \rightarrow {\dfrac{t}{8}}=\dfrac{ln(0.0078125)}{ln(1/2)}[/tex]

he Anwar family is planning to build a new home. They have hired 2 different architects to create blueprints for the house. Anderson Architects uses a scale of 1 in. to represent 1.5 feet. Charleston Architects uses a scale of 1.5 inches to represent 1 foot. If each group draws a room that is 12 inches by 12 inches on the plans, what is the difference in size in real life of the two drawings?
The difference in sizes in real life of the two scale drawing is 10 feet.
How to use scale to find the real length?They hired two different architect to create a blueprints for the house.
Anderson Architects uses a scale of 1 in. to represent 1.5 feet.
Therefore,
1 inches = 1.5 feet
Real life size of 12inches by 12 inches
12 inches = ?
size = 12 × 1.5 / 1 = 18 feet
Charleston Architects uses a scale of 1.5 inches to represent 1 foot.
Therefore,
1.5 inches = 1 foot
Hence,
Real life size of 12inches by 12 inches
12 inches = ?
size = 12 / 1.5 = 8 feet
Therefore, the difference in real life is 18 - 8 = 10 feet.

The triangles are congruent and the measures of angle ∠K ≅ ∠N
What are Congruent Triangles?Transformations change the size or position of shapes. Congruent shapes are identical, but may be reflected, rotated or translated. Scale factors can increase or decrease the size of a shape. Congruent Triangles simply mean the triangles that possess the same size and shape
The three sides are equal (SSS: side, side, side)
Two angles are the same and a corresponding side is the same (ASA: angle, side, angle)
Two sides are equal and the angle between the two sides is equal (SAS: side, angle, side)
A right angle, the hypotenuse and a corresponding side are equal (RHS, right angle, hypotenuse, side)
Given data ,
Let the first triangle be ΔJKL
