Step-by-step explanation:
f(x) = x² + 6x + 12
= (x² + 6x + 9) + 3
= (x + 3)² + 3.
Since a² >= 0 for all real values of a,
(x + 3)² >= 0 for all real values of x,
(x + 3)² + 3 >= 3 for all real values of x.
Hence f(x) >= 3. (Shown)
solve the system of equations
Answer:
x= -8
y=7
Step-by-step explanation:
make it so the x's cancel out
to do this multiply the bottom equation by 2
2x+3y=5
2x+4y=12
subtract to cancel out the x
-y=-7
y=7
now substitute y into one of the equations(I'm going to do x+2y=6)
x+2(7)=6
x+14=6
x=-8
What is the perimeter (please explain your answer)
Answer:
Answer: B. 38 mm
Step-by-step explanation:
The Perimeter of a Shape
The perimeter of a given shape is the sum of all exterior lengths surrounding the shape.
The figure shows a shape where all the external measures are given except the leftmost side.
This length is the sum of 3 mm + 10 mm = 13 mm.
Now calculate the perimeter:
P = 4 mm + 3 mm + 10 mm + 8 mm + 13 mm = 38 mm
Answer: B. 38 mm
PLEASE HELP!! The measure of angle 3 is 101 degrees. Find the measure of angle 4. ILL MAKE YOU BRAINLIEST.
Answer:
The answer is A aka 79*
Step-by-step explanation:
Based on the information given, the value of angle 4 will be 79°.
Solving angles.It should be noted that the sum of angles on straight line is always 180°.
In this case, the value of the other angle is 101°. Therefore, the value of angle 4 will be:
= 180° - 101°
= 79°

Answer:
The 3 possible values of x are;
6, 4 and 2
Step-by-step explanation:
If the triangle is isosceles, then two of the sides must be equal
So we equate the sides, 2 at a time to get the different values of x
3x + 4 = 2x + 10
3x-2x = 10-4
x = 6
3x + 4 = x + 12
3x-x = 12-4
2x = 8
x = 8/2 = 4
2x + 10 = x + 12
2x - x = 12-10
x = 2

When you multiple/divide by a negative you have to flip the sign
x < -6
Answer:
c
Step-by-step explanation:
Given
- 10 - 6x > 26 ( add 10 to both sides )
- 6x > 36
Divide both sides by - 6, reversing the symbol as a result of dividing by a negative quantity.
x < - 6 → c

What is a transversal?We know when a transversal intersects two parallel lines at two distinct points,
Two pairs of interior and alternate angles are formed such that the measure of interior angles are same and the measure of alternate angles is also the same.
So, (3y + 32)° + 73° = 180°, as pair of the corresponding exterior and interior angle form 180°.
(3y + 32)° + 73° = 180°.
3y + 105° = 180°.
3y = 180° - 105°.
3y = 75°.
y = 25°.
We also know that vertically opposite angles are equal,
∴ (3y + 32)° = z°.
75° + 32° = z°.
z° = 107°.

Let f (x) = 3x2 + 2 and g(x) = 2x, find f (g(x))
Answer:
D) 12x^2+2
Step-by-step explanation:
As we are dealing with composite functions, the rule is that f(g(x)) means whatever the value of g(x) is, we substitute that value for x in f(x):
[tex]f(x)=3x^2+2\\g(x)=2x\\f(g(x))=3(2x)^2+2\\f(g(x))=3(4x^2)+2\\f(g(x))=12x^2+2[/tex]
So, f(g(x))=12x^2+2, making D the right answer

DONE
What do the equations have in common and how are they different
Answer:
Slope -intercept for of equation 1: [tex]y=-2x+5[/tex]
Slope -intercept for of equation 2: [tex]y=-2x+3[/tex]
Looking at slope-intercept form of both equations, we have slope m = -2
Both have same slopes so, the lines are parallel.
Step-by-step explanation:
We need to write equations in slope-intercept form.
The general formula of slope-intercept form is: [tex]y=mx+b[/tex] where m is slope and b is y-intercept.
The first equation is:
[tex]2x+y=5[/tex]
Slope-intercept form:
[tex]y=-2x+5[/tex]
The second equation is: [tex]3y=9-6x[/tex]
Rearranging: [tex]3y=-6x+9[/tex]
Slope-intercept form:
[tex]y=\frac{-6}{3} x +\frac{9}{3}\\y=-2x+3[/tex]
Slope -intercept for of equation 1: [tex]y=-2x+5[/tex]
Slope -intercept for of equation 2: [tex]y=-2x+3[/tex]
Looking at slope-intercept form of both equations, we have slope m = -2
Both have same slopes so, the lines are parallel.
They have different y-intercepts.
