You plan to take $450 u.s. on a trip to south africa. how many rands is this if one u.s. dollar equals 3.70 rands?

1 answer:

8 0

$1 = 3.70 rands

$450 is simply 450 times $1, so multiply the conversion equation above by 450 on both sides.

450 * $1 = 450 * 3.70 rands

$450 = 1665 rands

Suppose y varies directly as x, and y=14 when x=4. What is the value of y when x=9

Katena32 [7]

Given :-

y varies directly as x, and y=14 when x=4.

To Find :-

the value of y when x=9 .

Solution :-

According to Question ,

y = kx ( k is constant )

When y = 14 and x = 4 ,

14 = k(4)
k = 14/4
k = 7/2

When x = 9 ,

y = 7/2*9
y = 63/2
y = 31.5

BRAINLIEST AND MAX PTS CONVERT y = 40x + 600 to point-slope form

IRISSAK [1]

Answer:

The answer to your question is y - 0 = 40(x - 15)

Step-by-step explanation:

y = 40x + 600

Convert to y - y₁ = m(x - x₁)

Process

1.- Factor 40 in the right side of the equation

y = 40(x - 15)

2.- Give the form of the point slope form

y - 0 = 40(x - 15)

where

y₁ = 0

m = 40

x₁ = 15

Solve the system of equations. 2x−9y=14 x=−6y+7

ipn [44]

Step-by-step explanation:

$put \: x \: into \: equation \: 1$

$2( - 6y + 7) - 9y = 14$

$- 12y + 14 - 9y = 14$

$- 21y + 14 = 14$

$- 21y = 14 - 14$

$- 21y = 0$

$\frac{ - 21y}{12} = \frac{0}{21}$

$y = 0$

$put \: y = 0 \: into \: equation \: 2$

$x = 6y + 7$

$x = 6(0) + 7$

$x = 0 + 7$

$x = 7$
