Answer:
-23
Step-by-step explanation:
rearrange to point slope form first
slope can be fine by y2-y1/x2-x1 (im using the first 2 points)
so 13-25 = -12 and -54-(-72) = 18, and the slope is -12/18 which is -2/3
then you can use any point (i used the first point) to create the point slope form which is y-ypoint=slope(x-xpoint) and equation would be y-25=-2/3(x+72)
turn it into slope intercept form by multiplying -2/3 within the equation and adding -25 on both sides
you will get y= -2/3x-23
and the y intercept will be (0, -23)
Simplifying
7(42x + -8) = 17(49 + x)
Reorder the terms:
7(-8 + 42x) = 17(49 + x)
(-8 * 7 + 42x * 7) = 17(49 + x)
(-56 + 294x) = 17(49 + x)
-56 + 294x = (49 * 17 + x * 17)
-56 + 294x = (833 + 17x)
Solving
-56 + 294x = 833 + 17x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-17x' to each side of the equation.
-56 + 294x + -17x = 833 + 17x + -17x
Combine like terms: 294x + -17x = 277x
-56 + 277x = 833 + 17x + -17x
Combine like terms: 17x + -17x = 0
-56 + 277x = 833 + 0
-56 + 277x = 833
Add '56' to each side of the equation.
-56 + 56 + 277x = 833 + 56
Combine like terms: -56 + 56 = 0
0 + 277x = 833 + 56
277x = 833 + 56
Combine like terms: 833 + 56 = 889
277x = 889
Divide each side by '277'.
x = 3.209386282
Simplifying
x = 3.209386282
Answer:
A.) If the origin is 0, then point c should be three lines to the right of 1 1/3 at number 1.
B.) 1/5
Step-by-step explanation:
Not completely sure if this is correct since im not postive of what its asking
Answer:
when y=3,X=15
here X is five times the value of y
so now when y= 5 then the value of X will be 25
hope you understand......
