Find the gradients of lines A and B.

pishuonlain [190]

Answer:

Gradient of line A = 4

Gradient of line B = -2

Step-by-step explanation:

To solve this question, we will use the formula for gradient passing through two points $(x_1,y_1)$ and $(x_2,y_2)$ ,

Gradient (m) = $\frac{y_2-y_1}{x_2-x_1}$

For line A,

Since, line A passes through (3, 6) and (4, 10)

Gradient of line A = $\frac{10-6}{4-3}$

= 4

For line B,

Since, line B passes through (1, 6) and (2, 4),

Gradient of line B = $\frac{6-4}{1-2}$

= -2

Which numbers can be placed in the blank to make the value of this expression a negative number? (-16) -

Genrish500 [490]

Answer:

All numbers greater than -16.

Step-by-step explanation:

Hello!

To keep this expression negative, we can subtract a positive number (numbers greater than or equal to 0), to give us an even smaller negative number.

Another option is to add a negative number so that the value is still negative. We can add any number that is larger than -16.

Answer: All numbers greater than -16

Lee and Maya are collecting leaves for an art project. Lee collect 24/100 of the tiral number of leaves needed. Maya collects 4/

Burka [1]

Answer:

The fraction of the total number of leaves did they collect altogether is $\frac{16}{25}$

Step-by-step explanation:

This question can be solved by a sum of fractions.

Lee collect 24/100 of the tiral number of leaves needed.

Maya collects 4/10 of the total number of leaves needed.

What fraction of the total number of leaves did they collect altogether?

This is the sum of 24/100 and 4/10.

The lesser common multiple between 100 and 10 is 100. So

$\frac{24}{100} + \frac{4}{10} = \frac{24 + 10*4}{1001} = \frac{64}{100}$

We can simplify by four

The fraction of the total number of leaves did they collect altogether is $\frac{16}{25}$
