Answer:

17) A(-1,1) B(-1,4) C(5,1)

18) (From origin moving rightwards)

A(0,0) B(a, 0) C(a,a) D(0,a)

Step-by-step explanation:

17) You just count the steps, how many steps left, right, up, or down

18) The first point is at the origin, so 0,0

The second point that lies on the x axis is (a,0) as it is a distance from the origin, 0 because it's on the x-axis.

The third point is (a,a) because it is a distance to the right of the origin AND a distance upwards from the x axis.

The fourth point (0,a) because it is on the vertical line (0) and is a distance above the origin.

pls help me do if u don't know how to do pls don't answer or else u will be reported I need it under 25min thank u

Vesna [10]

Answer:

see explanation

Step-by-step explanation:

given that V is directly proportional to u and inversely proportional to f , then the equation relating them is

V = $\frac{ku}{f}$ ← k is the constant of proportion

(a)

to find k use the condition when u = 1 and f = 3 , V = $\frac{1}{6}$ , then

$\frac{1}{6}$ = $\frac{k}{3}$ ( cross- multiply )

6k = 3 ( divide both sides by 6 )

k = $\frac{3}{6}$ = $\frac{1}{2}$

V = $\frac{u}{2f}$ ← equation of proportion

(b)

when f = 4 and V = 1 $\frac{1}{4}$ = $\frac{5}{4}$ , then

$\frac{5}{4}$ = $\frac{u}{2(4)}$ = $\frac{u}{8}$ ( cross- multiply )

4u = 40 ( divide both sides by 4 )

u = 10

Valentin [98]

Answer:

The smaller multiple is 100.

Step-by-step explanation:

The smaller multiple is 100. Let us assume the two consecutive multiples of 10 be 10x and 10x + 10. Hence, the smaller multiple of 10 is 100

5^-x +7=2x+4 solution

vodomira [7]

Simplifying

5x + 7 = 2x + 4

Reorder the terms:

7 + 5x = 2x + 4

Reorder the terms:

7 + 5x = 4 + 2x

Solving

7 + 5x = 4 + 2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2x' to each side of the equation.

7 + 5x + -2x = 4 + 2x + -2x

Combine like terms: 5x + -2x = 3x

7 + 3x = 4 + 2x + -2x

Combine like terms: 2x + -2x = 0

7 + 3x = 4 + 0

7 + 3x = 4

Add '-7' to each side of the equation.

7 + -7 + 3x = 4 + -7

Combine like terms: 7 + -7 = 0

0 + 3x = 4 + -7

3x = 4 + -7

Combine like terms: 4 + -7 = -3

3x = -3

Divide each side by '3'.

x = -1

Simplifying

x = -1
