The given line goes up 3 units for every 1 unit it goes to the right, so its slope is 3. If it is made to go through point (2, 1), it will be moved 2 units to the right. This means the y-intercept will be below its current value of 1. The only appropriate choice is ...
... C y = 3x - 5
5.35 + 3.8 + 2 = 11.15 pounds in total
Answer
D. 11.15
Answer:
Step-by-step explanation:
"Find the values of x that satisfy 3x - 2x^2 = 7." Please do not use " × " to represent a variable; " × " is an operator, the "multiply" operator.
Rearrange these three terms in descending order by powers of x:
-2x^2 + 3x - 7 = 0. Here the coefficients are a = -2, b = 3 and c = -7, and so the discriminant of this quadratic is b^2-4ac, or 9 - 4(-2)(-7), or 9 - 56, or -47.
Because the discriminant is negative, we'll have two different complex roots here. The quadratic formula becomes
-3 ± i√47 -3 ± i√47
x = ----------------- = -------------------
2(-2) -4
Answer:
y-3=7/6(x-4)
Step-by-step explanation:
the equation for point-slope form is y-y1=m(x-x1)
first let's find the slope (m)
the formula for slope is (y2-y1)/(x2-x1)
the given points: (4,3) and (-2,-4)
label the points:
x1=4
y1=3
x2=-2
y2=-4
now substitute into the equation
m=(-4-3)/(-2-4)
m=-7/-6
m=7/6
the slope is 7/6
now substitute the numbers into the equation for point-slope form
y-3=7/6(x-4)
Hope this helps :)!
