Paralell to 2x+y=-5
means it has same slope
means it is in form
2x+y=c where we have to find c
convert to slope intercept
minus 2x both sides
xint of 2
xint is where th eline crosses the x axis or where y=0, x=2
2(2)+0=c
2(2)=c
4=c
the equation is 2x+y=4
Answer:
$7.20
Step-by-step explanation:
First, we would have to find out how much to subtract from $62.
We need to multiply 90% and 62 or 0.9 x 62
When we finish this equation we get 54.8, which is what we need to subtract from 62 to see what 90% off is.
62 - 54.8 = 7.2, so therefore our answer is $7.20
<span>y=x-4
y=-x+6
---------------------
Substitute x - 4 for y in </span>y=-x+6
x-4=-x+6<span>
--------------------------------
Add X on each side
</span><span>x-4+x</span>=-<span>x+6+x
</span>2x - 4 = 6
--------------------------------------
Add 4 on each side
<span>2x-4+4</span>=<span>6+4
</span>2x = 10
------------------------------------------------
Divide by 2 on each side
2x ÷ 2 = 10 ÷ 2
x = 5
Now we have X
================================================================
To find Y we substitute 5 for x in y=<span>x-<span>4
</span></span>y = 5 - 4
y = 1
-----------------------------------------------------
Your answers are Y = 1 and X = 5

Step-by-step explanation:
Answer:
12.95a + 4.95 ≤ 75
Step-by-step explanation:
Given:
Cost of each DVD = $12.95
Total shipping fee = $4.95
Total amount as gift card = $75
Find;
Inequality
Computation:
Assume;
Number of DVD he purchase = a
So,
Total amount as gift card ≥ (Cost of each DVD)(Number of DVD he purchase ) + Total shipping fee
75 ≥ (12.95)(a) + 4.95
12.95a + 4.95 ≤ 75
