Answer:
P' = (2, -2)
Step-by-step explanation:
You have the x-value and the y-value of the pre-image, so all you have to do is plug that into the translation statement (x + 9 , y - 3).
Since x = -7 and y = 1 that would be (-7 + 9, 1 - 3), or (2, -2).
Answer:
7 ft or 72 inches
Step-by-step explanation:
Answer:
Step-by-step explanation:
X = whole number
Z = fraction numarater
Y = fraction denometer
you can do
X = X/1
Z and Y = Z/Y
X/Z = C(the new numartater)
Y/1 = Y
C/Y
Answer:
The mean score in the math test for class B=28.47
Step-by-step explanation:
<em>Step 1: Determine the total number of students in both Classes</em>
Total number of students=number in class A+number in class B
where;
number in class A=11 pupils
number in class B=15 pupils
replacing;
Total number of students=11+15=26 students
<em>Step 2: Determine total score for both classes</em>
Total score for both classes=total score for class A+total score for class B
total score for both classes=mean score for both classes×total number of students
total score for both classes=(49×26)=1,274
total score for class A=mean score for class A×total number of class A students
total score for class A=(77×11)=847
total score for class B=mean score for class B×total number of class B students
total score for class B=m×15=15 m
replacing;
1,274=847+15 m
15 m=1,274-847
15 m=427
m=427/15=28.47
The mean score in the math test for class B=28.47
