Answer:
(1, 4)
Step-by-step explanation:
y=x+3
y=3x+1
y=x+3
x+3=3x+1
x=3x-2
-2x=-2
x=1
y=1+3
y=4
Answer:
Let x represents the number of pants and y represents the number of shirts.
As per the statement:
Since, a clothing store are selling pants for $8.99 and shirts for $3.99
then;
total number of Pants cost is, $8.99x and total number of Shirt cost is, $3.99
Also, it is given that: You can spend as much as $60 and want to buy at least two pairs of pants.
then, we have the equation of inequality;
;......[1] where x, y are natural number.
x-intercept:
Substitute the value y= 0 in [1] and solve for x;


Simplify:

Since, x is in natural number;

Similarly.
For y-intercept:
Substitute the value x= 0 in [1] and solve for x;


Simplify:


Therefore, we have
;
and 
Answer:
-2x+25 D
Step-by-step explanation:
To determine how far it will go in an unspecified number of hours, we can let t = time in hours. The letter t will be our variable. Assuming that the car travels at the same speed, we can state that the rate is 55, and that will be our constant. The expression would then be:
Distance of car traveled in t hours, which we can denote as D(t) = 55 x t = 55t
This means that D is a function of t, and D represents the total distance traveled in t hours.
