Point $B$ has coordinates $(-3,-8)$ , while point $D$ has coordinates $(4,-6)$ .

So, to go from $B$ to $D$ the $x$ coordinate must go from $-3$ to $4$ , while the $y$ coordinate must go from $-8$ to $6$ . This means that the $x$ coordinate must grow $7$ units, while the $y$ coordinate must grow $2$ units.

So, the answer is the last one.

The same Honey is sold in two different size jars. Large jar= 540g for £4.10 Small jar= 360g for £2.81. By considering the amoun

Ray Of Light [21]

Answer:

From our calculations the large jar is the best value for money because a penny buys more honey

Step-by-step explanation:

<h2>In this problem we are expected to determine which purchase of honey is the cheapest ? large jar or small jar ?.</h2><h2 />

We will determine which has the best value for money using the quantity a pound can purchase.

firstly for the large jar.

if £4.10 will purchase 540g of honey then,

£1.00 will purchase xg

cross multiplying to find x will have

$x=$ $\frac{1.00*540g}{4.10}$

$x= 131.7grams$

Hence for the large jar a penny would buy 131.7g of honey

secondly for the small jar

if £2.81 will purchase 360g of honey then,

£1.00 will purchase xg

cross multiplying to find x will have

$x=\frac{1.00*360g}{2.81}\\x= 128.1gram$

Hence for the small jar a penny would buy 128.1g of honey

Select all the rates that are unit rates.

Nataly_w [17]

Answer:

$\frac{2/3}{1}$ and $\frac{3}{1}$

Step-by-step explanation:

Options

$\frac{1}{1/3}$ $\frac{2/3}{1}$ $\frac{2}{3}$ $\frac{3}{1}$ $\frac{1}{9}$

Required

Select the unit rates

Unit rate involve two items where the first item being measured can be any positive number, but the second item must be measured in units (i.e. 1)

For clarity:

If $\frac{a}{b}$ represents unit rate, then $b = 1$

Having said that:

Only $\frac{2/3}{1}$ and $\frac{3}{1}$ satisfy the condition of unit rates; others are not because they have a denominator other than 1

The average number of points you scored in the first 9 basketball games of the season was 23. What do you need in the 10th game

Vlada [557]

Answer:

B. 10n-207

Step-by-step explanation:

Given,

The average number of points of 9 games = 23,

∵ Sum of observations = their average × number of observations

So, the total points for 9 games = 9 × 23 = 207,

Now, if the average of 10 games is n,

Then the total points for 10 games = 10n,

Hence, the number of points earned in 10th game = the total points for 10 games - the total points for 9 games

= 10n - 207

i.e. OPTION B is correct.

Calculate the slope of the line passing through the two colored points below. (1,4) (-1,-1)

leonid [27]

Answer:

Slope = $\frac{5}{2}$

Step-by-step explanation:

We can define the slope as the "change in y values" divided by the "change in x values".

By change in, we mean, 2nd point MINUS the first point values.

The points given is:

(1,4) & (-1,-1)

<u>Change in y value:</u>

-1 - 4 = -5

<u>Change in x value:</u>

-1 -1 = -2

Slope is -5/-2 = 5/2

There is no answer choice. The correct answer is 5/2
