(x - 3)2 + (y + 2)2 = 4
Answer:
x = -y + 3
y = -x + 3
In standard form, it would be 2x + 2y = 6
Find the solution of this system of equations.
Separate the x- and y-values with a comma.
X-6y = -8
x - y = 12
Answer:
The answer is (16, 4)
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.

Answer:
PART A: 8(a + 2c)
PART B: -56
Step-by-step explanation:
PART A:
8a + 16c
8(a) + 8(2c)
8(a + 2c)

Step-by-step explanation:
Madison has a collection of 220 coins. How many coins represent 5% of her
collection?
Help me please
Answer:
11
220/x=100/5
(220/x)*x=(100/5)*x - we multiply both sides of the equation by x
220=20*x - we divide both sides of the equation by (20) to get x
220/20=x
11=x
x=11.
Mark's dad is three times older than Mark. Mark's sister is 2 years younger than Mark. (3m) The sum of their ages is 48. How old are Mark, his sister, and his dad?
Answer:
Age of Mark [tex]=10[/tex] years
Age of Mark's dad [tex]=30[/tex] years
Age of Mark's sister [tex]=8[/tex] years
Step-by-step explanation:
Let age of Mark be [tex]x[/tex] years.
Mark's dad is three times older than Mark
Age of her Mark's dad [tex]=3x[/tex]
Mark's sister is 2 years younger than Mark
Age of Mark's sister [tex]=(x-2)[/tex] years
The sum of their ages is 48.
[tex]x+3x+x-2=48\\5x-2=48\\5x=50\\x=10[/tex]
Age of Mark [tex]=x=10[/tex] years
Age of Mark's dad [tex]=3x=3(10)=30[/tex] years
Age of Mark's sister [tex]=x-2=10-2=8[/tex] years
Calculate the area of the parallelogram, giving your answer correct to 3 significant figures.
Answer:
114 units²
Step-by-step explanation:
The opposite sides of a parallelogram are congruent, so
AB = CD , that is
13x - 7 = 5x + 9 ( subtract 5x from both sides )
8x - 7 = 9 ( add 7 to both sides )
8x = 16 ( divide both sides by 8 )
x = 2
Then
5x + 9 = 5(2) + 9 = 10 + 9 = 19
3x = 3(2) = 6
The area (A) of a parallelogram is calculated as
A = bh ( b is the base and h the perpendicular height ), thus
A = 19 × 6 = 114 units²
Solve for x (X-9)(x+5)=8(21)

Answer:
The solution of the given inequality
x > 10
Step-by-step explanation:
Step(i):-
Given inequality
3 ( x-8) > -4 + x
Multiply
3 x - 24 > -4 +x
subtract 'x' on both sides , we get
3 x - 24 - x > - 4 + x - x
⇒ 2 x - 24 > - 4
Step(ii):-
Adding '2'4' on both sides , we get
⇒ 2x - 24 + 24 > -4 +24
⇒ 2 x > 20
Dividing '2' on both sides , we get
[tex]\frac{2x}{2} > \frac{20}{2}[/tex]
x > 10
Final answer:-
The solution of the given inequality
x > 10

Answer:
6, 7, 2, 3
Step-by-step explanation:
supplementary means that two or more angles add together to equal 180 degrees
a straight line equals 180 degrees so the intersecting of a line creates two angles that are supplementary. That means <5 is supplementary with 6 and 7.
<5=<1 because the lines intersecting it are parrell. Using the same thinking process for angle 1 as above, it is supplementary with 2 and 3. and since 1 is equal to 5 it is also supplementary to 2 and 3.
