Answers:
<h2>y = 7 when x = 1</h2><h2>y = 10 when x = 2</h2><h2>y = 13 when x = 3</h2>
Step-by-step explanation:
To solve this, we plug in the given values for x, 1, 2, and 3.
<h2>Scenario 1. What is y when x is 1?</h2>
y = 3x + 4
y = 3(1) + 4
y = 3 + 4
y = 7
<h2>Scenario 2: What is y when x is 2?</h2>
y = 3x + 4
y = 3(2) + 4
y = 6 + 4
y = 10
<h2>Scenario 3: What is y when x is 3?</h2>
y = 3x + 4
y = 3(3) + 4
y = 9 + 4
y = 13
Interesting pattern: y appears to be 3 times x
In other words: as x increases by 1, y will increase by 3. The slope of this line is y/x or 3/1 or simply, 3.
Answer:
a=76 b=83
Step-by-step explanation:
for a. we divide 6688(area) by 88 to find the width bc 88*w=6688
6688/88 is 76 so a=76
Since 312 is perimeter we have to subtract 73 twice and then divide that by 2 bc 73+73+L+L=312
(312-73-73)/2=83 so b=83
Answer:
the three consecutive odd integers are 9, 11, and 13.
Step-by-step explanation:
Let's say that the first odd integer is x. The second consecutive odd integer would have to be x+2. (It would not be x+1 because that would result in an even integer. The sum of any two odd numbers is even.) The third consecutive odd integer would be (x+2) +2 or x+4.
The sum of the first, twice the second, and three times the third can be written as:
x+2(x+2)+3(x+4)
This equals 70. We can now distribute and solve for x:
x+2(x+2)+3(x+4)=70
x+2x+4+3x+12=70(distribute)
6x+16=70(combine like terms)
6x=54(subtract 16 from both sides)
x=9(divide by 9)
Thus, the three consecutive odd integers are 9, 11, and 13
hope this helps :)
Answer:
$6650
Step-by-step explanation:
→ Calculate the decimal multiplier
100 - 30 = 70
70 ÷ 100 = 0.7
→ Multiply the decimal multiplier by the cost
9500 × 0.7 = 6650
