The answer is 69.3
Step by step solution - just subtract
Divide 24 by 6 because that is how many numbers are on the cube which would equal 4
Then multiply 4 and 2 because that's how many possibilities there are of rolling a number less than 4 and is even and the solution is 8
Answer:
To decide whether to add or subtract, determine if the values of the coefficients are the same or opposites:
. If the values are the same, subtract the equations.
• If the values are opposites or additive inverses, add the equations.
Step-by-step explanation:
Given

How to solve
Options (1) and (2) are incorrect because none of the options eliminate x or y.
For option (3),
- Check for the coefficients of x and y
- If they are the same (sign and value), then subtract; otherwise add
For instance:
Rewrite the second equation
The coefficient of y are the same, so we subtract;
<em>See that y has been eliminated</em>
Answer:
(-5 , 0)
(-2, 0)
(0, 20)
Step-by-step explanation:
y = 2x² + 14x + 20
x intercepts occur when y = 0
0 = 2x² + 14x + 20
0 = (2x + 4)(x + 5)
x = -5
or
x = -2
y intercept occurs when x = 0
y = 2(0)² + 14(0) + 20
y = 20
