use unitary method

for 5 it costs 330p

so for 1 choc it will cost 330/5

to get 9,

(330/5) =66

66 multiplied by 9 =594

therefore 9 will cost 594p

$5\ chock\ ices\ cost\ 330p\\
9\ chock\ ices\ cost\ x\\\\\
Ratio:\\
5-330\\
9-x\\\\Cross\ multiplication\\\\\
5x=330*9\\
5x=2970\ \ \ | divide\ by\ 5\\
x=594\\\\
9\ will\ cost\ 594p.$

Graphically determine the slopes of the line segments that create triangle ACD shown below. Write your final slopes in simplest

a_sh-v [17]

Answer:

Step-by-step explanation:

From the graph attached,

Coordinates of points A, C and D are,

A(-2, -7), C(-6, 7) and D(9, 2)

Slope of AD = $\frac{y_2-y_1}{x_2-x_1}$

= $\frac{-7-2}{-2-9}$

= $\frac{9}{11}$

Slope of CD = $\frac{7-2}{-6-9}$

= $-\frac{1}{3}$

Slope of AC = $\frac{7-(-7)}{-6-(-2)}$

= $-\frac{14}{4}$

= $-\frac{7}{2}$

What is the average rate of change of f(x) = −2x + 1 from x = −5 to x = 1?

Fiesta28 [93]

Average rate of change is just the slope between the 2 points
we can do this the long way or the smart way

long way, find the 2 points and find the slope between them
when x=-5, f(-5)=-2(-5)+1=10+1=11
when x=1, f(1)=-2(1)+1=-2+1=-1
so the points are (-5,11) and (1,-1)
the slope between them is (-1-11)/(1-(-5))=(-12)/(1+5)=-12/6=-2
the answer is B, -2

smart way
recognize that that is a linear equation and the slope between any 2 points will be the m in y=mx+b
f(x)=-2x+1
the slope is -2
the average rate of change is -2
answer is B. -2

Serga [27]

Answer:

She sell 2.075 kilograms of pears at the farmer's market.

Step-by-step explanation:

There is a mistake in the question some data is missing, so the correct question is below:

A farmer sells 8.3 kg of apples and pears at the farmer's market. 3 /4 of this weight is apples, and the rest is pears. How many kilograms of pears did she sell at the farmer's market?

Now, to find the kilograms of pears.

Total weight of apples and pears = 8.3 kg.

Weight of apples = $\frac{3}{4}$ of 8.3 kg.
