Easy 4,500 - 750x = y x is the number of months which is the independent variable (yes this is science in math) y which is the dependent variable which is the amount he has after x amount of months Ex: 2= x 4500 - 750 x 2 = 4500 - 1500 = $3,000 left in his account
Answer:
∠ ABC = 40°
Step-by-step explanation:
the 3 angles lie on a straight line ABE and sum to 180° , that is
50 - x + 80 + 2x + 40 = 180
x + 170 = 180 ( subtract 170 from both sides )
x = 10
Then
∠ ABC = 50 - x = 50 - 10 = 40°
Answer:
x = 120°
y = 60°
Step-by-step explanation:
As l and m are parallel
120° and x are corresponding angles, therefore x = 120°
y and x are supplementary angles along m therefore y = 180 - 120 = 60°
This tells us that p and q are not parallel as the alternate angles y and 70 are not equal. p and q would intersect somewhere to the left of the picture.
The complete statement is divide factors of ± 8 by factors of ± 1
<h3>How to complete the statement?</h3>
The polynomial is given as:
4x^3 + x^4 - 7x^2 - 8x - 8
Rewrite properly as:
x^4 + 4x^3 - 7x^2 - 8x - 8
The first term in the above equation is 1 i.e. 1x^4, while the last term is 8
To determine the possible rational roots, we divide the factors of the last term i.e. 8 by the factors of the first term i.e. 1
Hence, the complete statement is divide factors of ± 8 by factors of ± 1

Answer:
8cm
Step-by-step explanation:
1. x = width
length = 2x - 4
(2x - 4)x = 96
2x ^ 2 - 4x - 96 = 0
x ^ 2 - 2x - 48 = 0
(x + 6)(x - 8) = 0
Since the width cannot be negative, the width would be 8cm.
