Answer:
295 SUVs were sold, and 215 passenger vehicles.
Step-by-step explanation:
Let s and p represent the number of SUVs and p the number of passenger cars.
Then s = p + 80 and s + p = 510.
Substitute p + 80 for s in the second equation, obtaining:
p + 80 + p = 510, or:
2p = 430
Dividing both sides by 2 isolates p: p = 215.
Since s = p + 80, we add 80 to 215 here, obtaining s = 295.
295 SUVs were sold, and 215 passenger vehicles.
Answer:
1875L = 1.875x10^6 mL
multiply by density to get 2.14x10^6
multiply by percentage to get 6.63x10^4 g of NaCl (66.3 kg)
Step-by-step explanation:
1b ONLY LESS THAN
2c ONLY MORE THAN
3a HIGHEST means less than OR equal to
4d 7.54 miles OR MORE means greater than or equal to
A: 45x + 30y = 1350
Since we don’t know how many adults and children are in the group, we use x and y
b: x-intercept= 30 y-intercept=45
To find the x-intercept you need to isolate the variable. 45x/45 = x
Then you do the same thing to the other side. 1350/45 = 30
So x=30
Same thing with the y-intercept.
30y/30 = y 1350/30 = 45
y=45 (Not really sure what it means by “what they represent” but I thinks it’s that there are 30 adult tickets and 45 children tickets )
c: so our points are (30,0) and (0,45) so you would graph that.
To find how many children tickets were bought if there were 20 adult tickets just look at the photo I put. I don’t know how to explain this.
Hope this helps
Considering the given linear function, the inequality graphed is:

<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
The line intersects the y-axis at 2 units, hence the y-intercept is b = 2. The function also passes through (1,4), hence the slope is:
m = (4 - 2)/(2 - 1) = 2.
Thus the equation of the line is:
y = 2x + 2.
The left-side of the line is the values above the line, hence the inequality is:
B.
