d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (- 4, - 6) and (x₂, y₂ ) = (- 9, 6)
d = [tex]\sqrt{(-9+4)^2+(6+6)^2}[/tex]
= [tex]\sqrt{(-5)^2+12^2}[/tex]
= [tex]\sqrt{25+144}[/tex]
= [tex]\sqrt{169}[/tex]
= 13

C. 25% increase
D. 25% decrease
Answers
Answer:
D. 25% decrease
Step-by-step explanation:
Since it's clear that they read less books to find how much it decreased we multiply 100 with 15 then divide it by 20
100 × 15 ÷ 20 = 75 this result shows a 25% decrease.

Answer:
$50.40
Step-by-step explanation:
Adding the tax multiplies the amount by 1+8.1% = 1.081.
Adding the tip multiplies the amount by 1+17% = 1.17.
Then the amount with tax and tip is ...
$39.85 × 1.081 × 1.17 = $50.40
The Smith family paid $50.40 for the meal.

Answer:
1/ -6=12+1/3a
Rewrite the equation as 12+1/3a=−6.
12+1/3a= −6
Combine 1/3 and a.
12+a/3= −6
Move all terms not containing a to the right side of the equation.
a/3= −18
Multiply both sides of the equation by 3.
3⋅a/3=3⋅ −18
Simplify both sides of the equation.
a= −54
2/ -6 =12 -1/3a
Rewrite the equation as 12−13a=−6.
12−1/3a=−6
Combine a and /13.
12−a/3=−6
Move all terms not containing a to the right side of the equation.
−a/3=−18
Multiply both sides of the equation by −3.
−3⋅(−a/3)=−3 ⋅−18
Simplify both sides of the equation.
a=54

Question 4: x = 106
Question 5: x = 118
Step-by-step explanation:
Question 4: The exterior angles of a triangle are going to add up to 360.
128 + 126 = 254
360 - 254 = 106
x = 106
Question 5: The exterior angles of a polygon add up to 360 (a quadrilateral is a polygon).
A right-angle = 90
90 + 34 = 124
360 - 124 = 236
236 / 2 = 118
x = 118

B (27, 30)
Point A has coordinates (3, 2)
Point B has coordinates (27, 30)
Point C is marked on the diagram.
Work out the coordinates of C.
Answers
Answer:
The coordinates of C are (15,16)
Step-by-step explanation:
As we can see, point C lies half the distance of AB
So we can use the midpoint formula to get the coordinates of C
we have this as:
(x,y) = (x1 + x2)/2 , (y1 + y2)/2
(x1,y1) = (3,2)
(x2,y2) = (27,30)
Thus, we have
(x,y) = (3 + 27)/2, (30 + 2)/2
(x,y) = 30/2 , 32/2
(x,y) = (15,16)

Which of the following equations could you solve by first adding six and then dividing by negative three?
6 - 3 x = -9
+ 6 = -9
-3 x - 6 = -9
3 x - 6 = -9
Answers
Answer:
-3x - 6 = -9 (The third answer)
Step-by-step explanation:
When solving for x, you have to undo each operation. When solving -3x - 6 = -9, you have to undo the -6 first. To do this, add 6 to both sides. Then, you must undo the -3x. To do this, divide by -3 from both sides.
9 A rectangle of perimeter 42 cm is
pcm long and q cm broad. If the
difference between the length and
breadth is 9 cm. find
pand q
the area of the rectangle
Answers
Answer:
The correct answer is = p = 15 and q = 6.
Step-by-step explanation:
Given:
Perimeter of rectangle = 42 cm
p - q = 9 cm
length = p
width = q
we know:
Perimeter of rectangle= 2(l+w)
solution:
42 = 2(P+q)
21= p+q
Difference of p and q = 9 cm.
Then, P+q=21 .... 1
P-q=9 ....2
Adding both 1 and 2
2P = 30
P= 15cm and
q = 15-9
= 6cm
