Answer:

-0.5x + y + 0.5 > 0

Step-by-step explanation:

Let the equation of the line is,

y - y' = m(x - x')

where (x', y') is a point lying on the line

m = slope of the line

Since two points (1, 0) and (3, 1) lie on the line,

Therefore, slope of the line 'm' = \frac{y_2-y_1}{x_2-x_1}

m = \frac{1-0}{3-1}

m = \frac{1}{2}

Equation of line passing through (1, 0) and slope = \frac{1}{2} will be,

y - 0 = \frac{1}{2}(x-1)

y = 0.5x - 0.5

Since, line given in the graph is a dotted line therefore, its an inequality having sign of (> or <).

In this inequality shaded region is above the dotted line therefore, inequality representing the solutions by the shaded region will be,

y > 0.5x - 0.5

-0.5x + y + 0.5 > 0

Given that G=ab find the percentage increase in G when both a and b<br> increase by 10%
monitta

The percentage change in G is 21 %

<h3>What is Percentage change ?</h3>

Percentage change is defined as the increase or decrease in the value as compared to the original value multiplied by 100.

It is given that

G = ab

when a is increased by 10% the new a will be = 1.1 a

When b is increased by 10% the new b will be 1.1 b

So,

G' = 1.1a *1.1 b

G' = 1.21 ab

G' = 1.21

(G' - G)*100/G = (1.21-1)*100/1

The percentage change is 21 %

Martha and sarah leave block p and q towards q and p respectively simultaneously and travel in the same route. After meeting eac
olga_2 [115]

The average speed of Martha and Sarah is 32 km/h.

We need to know about the speed to solve this problem. Speed can be determined as the distance traveled divided by time. It can be written as

v = s / t

where v is speed, s is distance and t is time.

From the question above, we know that:

t sarah = 3 hours

t martha = 5 hours

v sarah = 40 km/h

By using the speed equation, we get the distance

vsarah = s / tsarah

40 = s/3

s = 120 km

Find Martha's speed

vmartha = s / tmartha

vmartha = 120 / 5

vmartha = 24 km/h

Find average speed

v = (vsarah + vmartha)/2

v = (40 + 24) / 2

v = 32 km/h

Hence, the average speed of Martha and Sarah is 32 km/h.
