Answer:
The Math Club must sell at least 50 pies to reach the goal
The graph in the attached figure
Step-by-step explanation:
Let
x-----> the number of sold pies
we know that
The inequality that represent the situation is
Solve for x
Divide by 4 both sides
The solution is the interval ------> [50,∞)
All positive whole numbers greater than or equal to 50
In a number line the solution is the shaded area at right of x=50 (close circle)
The Math Club must sell at least 50 pies to reach the goal
using a graphing tool
see the attached figure
It is 15.8 because 250 square root is 15.8...
Answer:
Step-by-step explanation:
line given is x-y+1= 0
you can rewrite it in slope intercept y=mx+b where m is the slope, and b is the y-intercept where the line meets the y-axis
x-y+1 =0 subtract x and 1 from both sides of the equation
-y = -x-1 multiply both sides by -1
y = x+1 so the slope of this line is 1 and the y-intercept is 1
If you draw this line you can see that there are actually 2 lines that form 45° angles with y=x+1 and pass through (-1, 2), one is vertical x= -1 and one horizontal y =2
Answer:
yes
Step-by-step explanation:
4: im not sure how to solve this or how to get the answer
5:
Distribute the Negative Sign:
= 3x^2+2x−3+−1(4x^2−8x+23)
= 3x^2+2x+−3+−1(4x^2)+−1(−8x)+(−1)(23)
= 3x^2+2x+−3+−4x^2+8x+−23
Combine Like Terms:
= 3x^2+2x+−3+−4x^2+8x+−23
= (3x^2+−4x^2)+(2x+8x)+(−3+−23)
= −x^2+10x+−26
Answer:
−x^2+10x−26
6: Distribute the Negative Sign:
= −13n^2−3n−6n^4+−1(13n^2+11n−2n^4)
= −13n^2+−3n+−6n^4+−1(13n^2)+−1(11n)+−1(−2n^4)
= −13n^2+−3n+−6n^4+−13n^2+−11n+2n^4
Combine Like Terms:
= −13n^2+−3n+−6n^4+−13n^2+−11n+2n^4
= (−6n^4+2n^4)+(−13n^2+−13n^2)+(−3n+−11n)
= −4n^4+−26n^2+−14n
Answer:
=−4n^4−26n^2−14n
7: and in math means to add
Combine Like Terms:
=4y^3+−8y+−y^3+5
=(4y^3+−y^3)+(−8y)+(5)
=3y^3+−8y+5
Answer:
=3y^3−8y+5
8: Answer choice 3
−5x^2+5x−2
9: answer is −8y
i had this in my notes from a while ago on my laptop so please see the image on how to solve this!
i hope this helps a lot!
