What is the value of the expression (x – 2y) (x + 2y) when x= 4 and y=1/2
Answer:
15
Step-by-step explanation:
First you would plug in the 4 and 1/2 in the x and y's places, making the expression (4 - 2 (1/2))*(4 + 2 (1/2). Then you solve (below).
(4 - 2 (1/2))*(4 + 2 (1/2)
(4 - 1)*(4 + 1)
(3)*(5)

Which is the graph of the line LaTeX: y-2=3\left(x-1\right)y − 2 = 3 ( x − 1 )?
Answer:
D.
Step-by-step explanation:
The equation given takes the point-slope form which is, [tex] y - b = m(x - a) [/tex]. Where,
(a, b) = (x, y) coordinates of a point on the line.
m = slope of the line .
To find which graph has a line equation of [tex] y - 2 = 3(x - 1) [/tex], look for the points which will give you something almost exactly as the equation if you substitute their values into [tex] y - b = m(x - a) [/tex].
Let's consider option D.
We have a given point (1, 2). a = 1, b = 2.
Substitute these into [tex] y - b = m(x - a) [/tex]
We have:
[tex] y - (2) = m(x - (1)) [/tex]
[tex] y - 2 = m(x - 1) [/tex]
As you can see, this looks almost exactly as
[tex] y - 2 = 3(x - 1) [/tex].
If you want to be certain that option D is the answer, find m by using the coordinates of any other point on the line and plug into [tex] y - 2 = m(x - 1) [/tex] to find m:
In graph D, let's take the points (0, -1)
[tex] -1 - 2 = m(0 - 1) [/tex]
[tex] -3 = m(-1) [/tex]
[tex] -3 = -m [/tex]
Divide both sides by -1
3 = m
m = 3.
Therefore, option D is the graph of the line [tex] y - 2 = 3(x - 1) [/tex].
Given the quadratic function f(x) = (x + 6)(x – 3):
The x-intercepts are
The y-intercept is
Answer:
Step-by-step explanation:
Given quadratic function is,
f(x) = (x + 6)(x - 3)
For x-intercept,
Substitute the value f(x) = 0.
(x + 6)(x - 3 = 0
x = 3, -6
So the x-intercepts will be,
(-6, 0) and (3, 0)
For y-intercept,
Substitute the value for x = 0,
f(0) = (0 + 6)(0 - 3)
= -18
Therefore, y-intercept of the given quadratic function will be (0, -18).

-4p+(-6p) combine like terms to create an equivalent expression
Answer:
-10p
Step-by-step explanation:
-4p+(-6p) for me I like to think of the negative or subtraction sign
overpowering the positive or addition sign
so in this case
-4p-6p
then since the variable p is the same -4-6 is -10
the end result is -10p

“Write an equation and solve for the unknown” I know it’s a lot but can someone help me with this
Answer:
g) x = 30
h) x = 30
i) m = 55
j) x = 24
k) k = 45
Step-by-step explanation:
G)
all angles of a triangle add up to 180.
the square in the bottom right of the triangle is 90 btw
2x + x + 90 = 180
3x + 90 = 180
3x + 90 - 90 = 180 - 90
3x = 180 - 90
3x = 90
3x/3 = 90/3
x = 30
H)
this is an Isosceles triangle.
that means the bottom two angles are equal.
75 + 75 + x = 180
x + 150 = 180
x + 150 - 150 = 180 - 150
x = 180 - 150
x = 30
I)
2m is supplementary to the bottom right angle of the triangle.
that means they add together to make 180.
80 + 30 + (180 - 2m) = 180
110 - 2m = 180 - 180
110 - 2m = 0
110 = 2m
110/2 = m
55 = m
J)
to save time I'm not going to write out the steps, its the same as the i.
2x + 3x + (180 - 120 ) = 180
5x + 60 = 180
5x = 180 - 60
5x = 120
x = 120/5
x = 24
K)
imagine this as a triangle and a square.
sorry I'm not sure how to explain this -.-
but the equation would be
k + k + 90 = 180
2k + 90 = 180
2k = 180 - 90
2k = 90
k = 45
L)
Im not sure how to solve this, I'm sorry :( hope you figure it out!
What is the area of this triangle? And it's not 60, I already checked. PLEASE EXPLAIN!!!!
Answer:
A = 4 cm^2
Step-by-step explanation:
The area of a triangle is
A = 1/2 b*h
The base is 4 and the height is 2
A = 1/2 ( 4*2)
A = 1/2*8
A = 4 cm^2
Answer:
4
Step-by-step explanation:
A = BH/2
or Area = Base multiplied by Hieght divided by 2.
(b)4 x (h)2 = 8
8/2 = 4

C. yes
Step-by-step explanation:
A. not enough information is given other than the fact that ∠E ≡ ∠B (45°)
B. SAS (side angle side). To make ∠ABC into ∠DEF, you need to multiple the side lengths in ∠ABC by 3/2
12/x = 8 .... rearrange .... x = 3/2
C. AA (angle angle). ∠A is congruent to ∠Y and this is given by those two lines. ∠B is congruent to∠Z and this given because it has one line. This means that the other angle (C and X) would be congruent.

12 = 7 - 3x + 5x
Answer: 12=7−3x+5x
Step 1: Simplify both sides of the equation.
12=7−3x+5x
12=7+−3x+5x
12=(−3x+5x)+(7)(Combine Like Terms)
12=2x+7
12=2x+7
Step 2: Flip the equation.
2x+7=12
Step 3: Subtract 7 from both sides.
2x+7−7=12−7
2x=5
Step 4: Divide both sides by 2.
