I would use subsitution
y=x-7
sub x-7 for every x
5x+2(x-7)=14
5x+2x-14=14
add 14 to both sides
7x=28
divide both sides by 7
x=4
sub
y=x-7
y=4-7
y=-3
x=4
y=-3
(4,-3)
<h2>Greetings!</h2>
Anything to the power of 1 is still 1, because 
is simply 1 x 1 x 1 x 1 x 1 = 1 ect.
<h3>So this changes the equation to 1x = 2, which means that:</h3>
x = 2
<h2>Hope this helps!</h2>
This problem can be solved using two equations:
The first represents the total trip, which is the miles driven in the morning added to those in the afternoon. Let's call the hours driven in the morning X and the hours driven in the afternoon Y. We get: X + Y = 248.
The second equation relates the miles driven in the morning compared to the afternoon. Since 70 fewer miles were driven in the morning than the afternoon, then X = Y - 70.
Now substitute the equation for morning hours (equation 2) into the total miles equation (equation 1). We get:
(Y - 70) + Y = 248
2Y - 70 = 248
2Y = 318
Y = 159
We know that Winston drove 159 miles in the afternoon.
To find the morning hours, just substitute 159 into the equation for morning hours (equation 2)
X = 159 - 70
X = 89
We now know that Winston drove 89 miles in the morning.
We can check our work by plugging both distances into the total distance equation: 89 + 159 = 248
F(x)= (x+13)(x-2) in expanded form, it would be x^2+11x-26
Answer:
a) 60%
b) $1240
c) $744
Step-by-step explanation:
a. the company's percentage %
If Jack pays 40%, the company pays the other 60%
b. the total premium $
Jack payment is 40% of the total. 40% of the total is 496. So:
The total premium is $1240.
c. the company's payment $
The company payment is 60% of 1240. So 0.6*1240 = 744.
