Answer:
The equation of the line that has a slope of -2 and y-intercept of 1 will be:
Step-by-step explanation:
The slope-intercept form of the line equation
where
Given
The slope m = -2
y-intercept b = 1
We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
It is already stated that the y-intercept = -1
It means at y = 1, x = 0
Thus, we have the point (0, 1)
Now using the slope-intercept form
y = mx+b
substituting m = -2 and b = 1
y = -2x + (1)
y = -2x+1
Therefore, the equation of the line that has a slope of -2 and y-intercept of 1 will be:
Answer:
Z=X(v¹⁷+v¹⁵+v¹²) + Y(v²⁰+v¹⁸+v¹⁵)
Step-by-step explanation:
For the the first child of age 1 yea to be paid an investment of X at age 18 will be Xv¹⁷ and an investment of Y at age 21 will be Yv²⁰·
also for then 3 years old child to be paid an investment of X at age 18 will be Xv¹⁵ and an investment of Y at age 21 will be Yv¹⁸
lastly for the 6 years old child be paid an investment of X at age 18 will be Xv¹² and an investment of Y at age 21 will be Yv¹⁵·
Hence the investment Z must be equal to the summation of all this values
Z=X(v¹⁷+v¹⁵+v¹²) + Y(v²⁰+v¹⁸+v¹⁵)
Answer:
ans is -2
Step-by-step explanation:
(-3-2)/(0+2)=-2
Answer:
D
Step-by-step explanation:
3 - 7 = -4 and 3(3) + 2(-7) = -5, so D is the only choice that is correct for both inequalities.
