1.
a. 5
b.5300
c.-891
d.-312
2.
a. y=3
b.x=-3
c.z=4
d. y=4.33
Step-by-step explanation:
1
a.Solution:
-32÷8×2+2+1
=-4×2+2+1
=-8+2+1
=-8+3
=-5
b. Solition:
53×9+109×53
=477+5777
=5300
c. Solution:
-891
d. Solution:
-63×12+12×37
=-756+444
-312
2.
a. Solution:
5y-3+3=-18+3
5y=-15
y=-15/5
y=3
b. Solution:
-3x-9+9=0+9
-3x=9
x=9/-3
x=-3
c. Solution:
4+3-3(z-8-3)=-23-3
4(z-5)=-20
4z-20=-20
4z-20+20=-20+20
4z
z=4
d. Solution:
1-2+2(y-4+2)=5+2
3(y-2)=7
3y-6=7
3y-6+6=7+6
3y=13
y=13/3
y=4.33
Answer:
40
Step-by-step explanation:
highest=2(lowest)+7
Replace the variables here:
87=2(lowest)+7
minus 7 on both sides
80=2(lowest)
divide both sides by 2
40=lowest
Answer:
1. remove parantheses by multiplying factors
2. use exponent rules to remove parentheses in terms with exponents
3.combine like terms by solving coefficients
4.combine the coefficients

A correct sequence of similarity transformations that shows AABC~ ADEF is that D. a counterclockwise rotation of 90 degrees about point E followed by dilation with a scale factor of 2 centered at point E.
<h3>What is similarity
transformation?</h3>
A similarity transformation refers to a geometric similarity, or to a matrix transformation that results in a similarity.
In this case, the correct sequence of similarity transformations that shows AABC~ ADEF is that a counterclockwise rotation of 90 degrees about point E followed by dilation with a scale factor of 2 centered at point E.
