Mathematics

Answer:

The slope would be -2 1/3 or -2.3 repeating

Step-by-step explanation:

The first point would be (-4, 9). The next point is (2, -5). We can tell that the slope will be negative, because the x values increased by 6, but the y values decreased by 4.

The slope would be -2 1/3 or -2.3 repeating

I Hope That This Helps! :)

vova2212 [387]

Answer:

$40\%x + x = 14 \\ \\ \\ \frac{40}{100} x + x = 14 \\ \\ \\ \frac{4}{10} x + x = 14 \\ \\ 0.4x + x = 14 \\ \\ 1.4x = 14 \\ \\ x = \frac{14}{1.4} \\ \\ \\ x = \frac{140}{14} \\ \\ \\ x = 10$

The image below shows two dilated figures with lines IJ and JK drawn. If the smaller figure was dilated by a scale factor of 2,

Arte-miy333 [17]

Answer:

IJ = 2*KL

Step-by-step explanation:

Given that the smaller figure was dilated to create the bigger figure with a scale factor of 2, it therefore means, the dimensions of the smaller figure was increased by times 2 of its dimensions to create the bigger figure.

Thus, the relationship that would exist between line IJ and KL, is that IJ is twice the size of KL.

The relationship is: IJ = 2*KL

(-8,-4)&(2,-9) fint the distance between each pair of points

Makovka662 [10]

Answer:

$5 \sqrt{5}$

Step-by-step explanation:

We want to find the distance between (-8,-4) and (2,-9).

We use the distance formula:

$d = \sqrt{ {(x_2-x_1)^2} +(y_2-y_1)^2 }$

We substitute the coordinates to get:

$d = \sqrt{ {(2- - 8)^2} +( - 9 - - 4)^2 }$

We simplify to obtain:

$d = \sqrt{ {(2 + 8)^2}+( - 9 + 4)^2 }$

Add the numbers within the parenthesis to get:

$d = \sqrt{ {(10)^2}+( -5)^2 }$

Find the squares of the numbers under the radical

$d = \sqrt{ {100}+25}$

$d = \sqrt{125} = 5 \sqrt{5}$

3+1 + - + ... ?<br> What is the sum of the first 7 terms of this geometric series: 3+1+ 3

mote1985 [20]

Answer:

Step-by-step explanation:

3+1+3+1+3+1+3= 15 this is what it would look like if you write it out. To save time do 3 times 4 to get 12 and then just add three ones to 12 to get 15.
