I would use subsitution
y=x-7
sub x-7 for every x
5x+2(x-7)=14
5x+2x-14=14
add 14 to both sides
7x=28
divide both sides by 7
x=4
sub
y=x-7
y=4-7
y=-3
x=4
y=-3
(4,-3)
3.67 teaspoons, and 1 divided by 17 is 0.05 teaspoons. (All you have to do is divide the teaspoons by X(17).
Answer:
y= -3x + 11
Step-by-step explanation:
Slope formula: y^2- y^1 divide by x^2- x^1
y^2 is -1
y^1 is 5
x^2 is 4
x^1 is 2
-1 - 5 = -6
4 - 2 = 2
-6/2 = - 3
Y-intercept: Using the slope and either of the two points, replace the <em>y</em><em>,</em><em> </em><em>m</em><em>,</em><em> </em>and <em>x</em> in y= mx+b.
Using (2, 5)
5= -3(2) + b
5= -6 + b
Add 6 to both sides in order to eliminate -6.
-6 + 6 = 0
5 + 6 = 11
11 = b
Combine your slope-intercept formula:
y= 3x + 11
The result of the simplified polynomial in standard form is 26x-67-x^2.
Given that,
- There is (x-8)^2.
- And, 10x - 3
- The above (x - 8)^3 should be subtracted from 10x-3.
Based on the above information, the equation be like
= (10x - 3) - (x - 8)^2
= 10x - 3 -(x^2-16x+64)
= 10x - 3-x^2+16x-64
= 26x-67-x^2
Therefore we can conclude that the result of the simplified polynomial in standard form is 26x-67-x^2.
