Answer:
(a) (4, 8)
Step-by-step explanation:
Apply the transformation rule to the coordinates of point H.
(x, y) → (x +8, y +5)
H(-4, 3) → H'(-4 +8, 3 +5) = H'(4, 8)
Answer:
663
Step-by-step explanation:
the total number of students can be determined using this equation :
(total ratio of Chinese and Indian students / total ratio of students) x n = 468
total ratio of Chinese and Indian students = 4 + 8 = 12
total ratio of students 4 + 8 + 5 = 17
N = TOTAL NUMBER OF STUDENTS
12/17) x n = 468
multiply both sides of the equation by 17/12
n = 663
Answer:
a) -3
b) 5
c) 7
d) 4
Step-by-step explanation:
We have the function 
a) We need to find the coefficient of
.
This means that we need to find out what number is alongside the
in this equation. From the function, we can find that it is -3
b) Now we need to find the degree of
. Recall that the degree refers to the highest power of x that is present. As
is the largest power, our degree would be 5.
c) The constant term refers to the number within the function that does not have any x's with it. In this function, that number would be 7.
d) Now we need to find the number of terms. For this one, we just need to count how many terms are separated by + or - signs. There are 4 in this function.
First simplify the expression into polynomial form,



Now factor into,

Which means the solutions are,


and then two complex solutions because determinant of the third factor
,

Answer:
Tom weighs 70 pounds
Step-by-step explanation:
first, you have to set up your equation which would be, x + 3x = 280.
The x stands for Tom's weight and the 3x stands for three times Tom's weight for the dad. You would then add your like terms, then divide by 4 to get 70.
x + 3x = 280
4x = 280
280/4 = 70
x = 70
Hope this helps!
