Answer:
(2,-2)
Step-by-step explanation:
Answer:
x = 2, y = -2
Step-by-step explanation:
This means that [tex]-3x + 4 = 4x - 10[/tex]
Now, you just have to solve the equation
[tex]-3x + 4 = 4x - 10\\\\[/tex]
add 3x to both sides
[tex]4 = 7x - 10[/tex]
add 10 to both sides
[tex]14 = 7x[/tex]
divide both sides by 7
[tex]x = 2[/tex]
Substitute this into the equation [tex]y = -3x + 4[/tex]
[tex]y = -3(2) +4\\y = -6 + 4[/tex]
[tex]y = -2\\[/tex]
When you multiply two complex numbers in polar form, what happens to the angles?
The angles get added.
Let z = r exp(i θ) and w = s exp(i φ). Then
zw = rs exp(i θ) exp(i φ) = rs exp(i (θ + φ))

8x - 16 = -4x - 4(1-6x)
please show work
Answer:
x= -1
Step-by-step explanation:
8x - 16 = -4x - 4(1-6x)
8x - 16 = -4x - 4+24x
8x - 16 = 20x-4
8x - 16+16 = 20x-4+16
8x = 20x+12
8x-20x = 20x-20x+12
-12x=12
Divide both by -12, and you get -1.
[tex]8x - 16 = - 4x -4 + 24x[/tex]
Solve the equation for x-term by making x as the subject.[tex]8x + 4x - 24x = 16 - 4 \\ 12x - 24x = 12 \\ - 12x = 12 \\ x = \frac{12}{ - 12} \Longrightarrow \frac{1}{ - 1} \Longrightarrow - 1 \\ x = - 1[/tex]
Answer Check by substituting x = -1 in the equation.[tex]8( - 1) - 16 = - 4( - 1) - 4 + 24( - 1) \\ - 8 - 16 = 4 - 4 - 24 \\ - 24 = 0 - 24 \\ - 24 = - 24[/tex]
The equation is true for x = -1.

A triangle has two equal sides.
a)
What is the special name for this type of triangle?
b)
One of the angles in this triangle measures 100°.
What is the size of each of the other two angles?
+
Answer:
A. isosceles triangle
B. each two angles equal 40°
Step-by-step explanation:
A. the special name for this type of triangle is isosceles triangle.
As isosceles triangles are the triangles whose base angels are equal and the Two sides are equal.
B.
given
one angle = 100°
As it is isosceles triangle so two angles are equal. So let the angle be x
Then
x + x + 100° = 180° [sum of angles of triangle ]
2x = 180° - 100°
2x = 80°
2x = 80°
x = 40°
Hey there ..
Here is ur answer ..
a) Isosceles triangle
b) 40° and 40°

Answer:
x=65
Step-by-step explanation:
Step 1: Add -3 to both sides.
√x−1+3+−3=11+−3
√x−1=8
Step 2: Solve Square Root.
√x−1=8
x−1=82(Square both sides)
x−1=64
x−1+1=64+1(Add 1 to both sides)
x=65
Check answers. (Plug them in to make sure they work.)
x=65(Works in original equation)
A small box holds 40 stuffed toys. A large box holds 150% as many stuffed toys as than a small box how many stuffed toy does the large box hold.
Answer: 60
Step-by-step explanation:
From the question, we are informed that a small box holds 40 stuffed toys and that a large box holds 150% as many stuffed toys as that of a small box.
The number of stuffed toy that the large box hold would be calculated as:
= 150% × 40
= 150/100 × 40
= 1.5 × 40
= 60

Answer:
D. all real numbers
Step-by-step explanation:
4(x+3)-7greater than or equal to x+3(x+1)
4x+12-7> or equal to x+3x+3
4x+5>or equal to 4x+3
so, by testing
if x=1, is it true that 4x+5 is greater than or equal to 4x+3
4(1)+5=4(1)+3
9=7
hence it true 9 is greater than 7
Option D is collect
Answer:
Step-by-step explanation:
4(x+3) - 7 ≥ x + 3(x + 1)
4x + 12 -7 ≥ x + 3x + 3
5≥3
so this answer tells us that this equation will always be true no matter what number you plug in for x ... so all real numbers works
