Step-by-step explanation:
Step-by-step explanation:
thr standard form for a quadratic equation is:
ax²+bx+c
in this example, a=1, b=(-1), c=(-42)
His statement is incorrect since the opposite of -23 is 23 which is a positive number.
There are 5 large dogs and 3 small dogs
<h3><u>Solution:</u></h3>
Let "S" be the number of small dogs
Let "L" be the number of large dogs
<em><u>Given that There are a total of 8 small and large dogs</u></em>
So we can frame a equation as:
number of small dogs + number of large dogs = 8
S + L = 8 ------- eqn 1
<em><u>You realize there are 2 more large dogs than small dogs</u></em>
Number of large dogs = 2 + number of small dogs
L = 2 + S -------- eqn 2
<em><u>Let us solve eqn 1 and eqn 2 to find values of "L" and "S"</u></em>
Substitute eqn 2 in eqn 1
S + 2 + S = 8
2S + 2 = 8
2S = 6
<h3>S = 3</h3>
Substitute S = 3 in eqn 2
L = 2 + 3 = 5
<h3>L = 5</h3>
Thus there are 5 large dogs and 3 small dogs
