(-5,-3), Parallel to -3x - 7y = 10, Put in slope-intercept form.
So, we must find the slope of this first.
-3x - 7y = 10
Add 3x to both sides.
-7y = 3x + 10
Divide both sides by -7.
y = -3/7x - 10/7
So, our slope is -3/7.
Remember, if you're looking for a line that is parallel to something, the slopes always stay the same.
*Also remember that slope-intercept form is y = mx+b*
Where m = slope, and b = y-intercept.
We have the points (-5,-3) so our y-intercept is -3.
Our slope is -3/7.
So, simply plug in those values into the slope-intercept form equation! :)
y = mx + b
y = -3/7x - 3
~Hope I helped!~
<span>We have to use PEMDAS for this expression.
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction
</span>(2x^2 - 5x + 4) Original Mathematical Expression
[2(7)^2 - 5(7) + 4] Plugging the value of x, 7 into expression.
There are parentheses, so that means we have to work in them.
There are exponents, so we have to do those first.
[2(49) - 5(7) +4] Exponents.
There is multiplication, that we can do, so we do that left to right.
[98 - 35 + 4] Multiplication.
There is no division.
There is addition and subtraction, so we do those left to right.
[63 + 4] Subtraction.
67 Addition.
Final Answer: 67
Answer:
$155
Step-by-step explanation:
<u>Variable</u>
Ticket=T
Shirts=S
Poster=P
4 concert ticket so 4T
3 t-shirts so 3S
Poster is P
So the Expression is: 4T+3S+P=Total cost
<u>To find total cost:</u>
Concert at $25 each for 4 people (multiply)
25*4=$100
3 t-shirts for $15 (multiply)
15*3=$45
Poster is $10
Add the totals together:
100+45+10= $155
Therefore, the total cost is $155 for the things they purchased.
Hope this help!!!
Have a nice day :)
