Answer:

y=9.75x+60

Step-by-step explanation:

We want our equation to look like y=mx+b

Let's start out by calculating the slope

$\frac{118.5-89.25}{6-3}=9.75$

we have

y=9.75x+b

we know that when x= 3 y= 89.25

89.25=9.75(3)+b

solve for b = 60

Answer:

ans: a) x/3 + y/2 = 1

b) y = (1/3)x + 11

Step-by-step explanation:

equation of line in double intercept form is

x/a + y/b = 1

and equate given equation with y = mx + c

so m= -3

so new slope perpendicular to given line is

M = -1/m = 1/3

C in equation denotes y intercepts

F(x)=-x^2-5 find the range

lina2011 [118]

$x = \frac{ - b}{2a} \\ = \frac{0}{2(1)} = 0 \\ f(0) = (0)^{2} - 5 \\ = 0 - 5 = - 5$
The vertex is at (0,-5), therefore the range goes from (-infinity, - 5]

Royce had 171.26 in digital Money.so far this month he has made deposits of $60.76, 29.79 and $89.31 into his account, while he

Nesterboy [21]

Answer:

$\$234.02$

Step-by-step explanation:

we know that

The amount Royce had plus the amounts deposited minus the amounts withdrawn is equal to the amount Royce currently has now

Let

x ----> the amount Royce currently has now

$x=171.26+(60.76+29.79+89.31)-(14.82+46.76+55.52)$

$x=171.26+(179.86)-(117.1)$

$x=\$234.02$
