Answer:
m∠1 = 52, m∠2 = 60
Step-by-step explanation:
68 and ∠2 are interior angles. 128 is exterior angle.
Formula : -
Sum of two interior angles = Exterior angle
68 + ∠2 = 128
∠2 = 128 - 68
∠2 = 60
∠1 and 128 are linear pair angles. Sum of linear pair angles is 180,
∠1 + 128 = 180
∠1 = 180 - 128
∠1 = 52
Martin has 128 pencils that he is putting
into boxes. Each box holds 6 pencils. If he
puts all the pencils into boxes, how many
more pencils will he need to fill the last box
completely?
128 pencils divided by 6 pencils that can be put in a box; 128÷6=21 with a remainder of 3
Martin needs 3 more pencils for the last box, beacuse he has 3 leftovers and 6 can go into the box. 6-3=3

Line segment XY has endpoints X(5,7) and Y(-3,3)
y=-2x+7
Step-by-step explanation:
line segment xy has endpoints x(5 7) and y(-3 3)
for the equation of the perpendicular bisector of line segment xy
slope of line segment xy = 7-3 / 5+3
= 4/8
=1/2
so slope of perpendicular bisector is -2
as m1m2= -1 or m1= -1/m2
As perpendicular bisector goes through midpoint of xy , let's find midpoint of xy
midpoint(x,y) = (5-3 / 2 , 7+3 / 2)
=(2/2, 10/2)
=(1,5)
find the equation of line(perpendicular bisector) passing through (1,5) and the slope -2
y-5 = -2(x-1)
y-5 =-2x+2
y=-2x+7

Solve the inequality and graph the solution on the line provided. 4 + 6 x < 4
Answer:
inequality: x<0
Step-by-step explanation:
Given that f(x) = x^2– 5x– 36 and g(x) = x + 4, find (f +9)(x) and express
the result in standard form.
Answer:
x^2 -4x-32
Step-by-step explanation:
f(x) = x^2– 5x– 36
g(x) = x + 4
(f +g)(x) = x^2– 5x– 36 + x + 4
Combine like terms
= x^2 -4x-32
Answer:
[tex] \longmapsto \: f(x) = {x}^{2} - 5x - 36 \\ \longmapsto \: g(x) = x + 4 \\ \longmapsto(f + g)(x) \\ = f(x) + g(x) \\ = ( {x}^{2} - 5x - 36) + (x + 4) \\ = {x}^{2} - 5x - 36 + x + 4 \\ = \boxed{ {x}^{2} - 4x - 32}[/tex]

Use vale 3.14 to help with answer
Answer:
circumference: 12.56 cm
area: 12.56 cm^2
Step-by-step explanation:
1. The formula to find the circumference of a circle is [tex]2\pi r[/tex] or [tex]\pi d[/tex]. In this case, pi is approximated to 3.14, and the diameter is 4.
[tex]3.14 * 4[/tex] [tex]12.56[/tex]Therefore, the circumference is 12.56 cm.
2. The formula to find the area of a circle is [tex]\pi r^2[/tex], and in this case, pi is approximated to 3.14. Also, the radius is half the diameter: 4/2 = 2.
[tex]3.14 * 2^2[/tex] [tex]3.14 * 4[/tex] [tex]12.56[/tex]Therefore, the area is 12.56 cm^2.

Answer:
(D)
Step-by-step explanation:
Becuase 81 is greater than 9 and 9 is less than 12 (I hope this helps) :)
Step-by-step explanation:
12 less ( subtracting 12 from something else)
the quotient-Dividing between two values
A number: let's use Y
so we want to substract 12 from the product of y/9
(Y/9) -12.
So 81 is greater than 9 but 9 is less than 12.

A bank offers an investment account with an annual interest rate of 1.28%
compounded monthly. Nicole invests $34,000 into the account for 3 years.
Answer:
$49320.40
Step-by-step explanation:
Let's work the small steps first. Nicole invests $34,000 into the bank, but the catch is that the value increases by "x%" every month, for 3 years. Since there are 12 months in a year, we know we will have to multiply 12 by 3, which yields us 36 months. Now we multiply our "x" value, which is 1.28% by 36, which yields us 45.06%. When we add that extra 45.06% to the already existing $34,000, the money increases to $49320.40
Your gain was +$15,320.40
If you're wondering what the one year value is, divide 45.06% by 3, and you will get 15.02%. If your instructor/teacher asks for the one year mark, the answer is $39106.80
Your gain was $5106.80
The two year mark would yield Nicole $44,213.60. The rate was 30.04% at two years, which means Nicole gained an extra $10213.60.
I hoped this helped buddy!
