Answer:
Step-by-step explanation:
2.9687=
Answer:
You first start by making your equation: 45 +.25x = 70 +.15x. then subtract .15x from both sides. it should look like 45 +.10x = 70. subtract 45 from both sides then you get .10x = 25. divide 10 to both sides and you get 250. so the two companies will be the same at 250 texts.
Step-by-step explanation:
First off, let's keep in mind that perpendicular lines have negative reciprocal slopes, hmmm so what's the slope of y = 2x + 5?
well, notice, that equation is in slope-intercept form, thus

.

so, we're really looking for the equation of a line whose slope is -1/2 and runs through 1,4.
The answer is D because you have to divide 812 by 25.3
Answer:
$65
Step-by-step explanation:
All 12 of the televisions have extended warranties so 12*15= 180
Then subtract 960-180= 780
Now divide 780/12 = $65
