Pleaseeee help on question 3 and 5 pleaseeeee wuick thank youuuuuuuuu

Answer:

3a, 13cm 5, 1:200

Step-by-step explanation:

In the question 3 you just have to divide all of those numbers with that 5000, maybe also make them cm so it makes more sense. So 650m = 65000cm:5000= 13cm

then for the question 5, make the km to cm, so 4.2km would be 420000cm. Then you have to divide that 420000cm with the 21 cm, so 420000:21= 200. Then the scale should be 1:200

I had difficulties with these as well. If you need extra help with the task 3 please pm me :)

What is the the slope that passes through the points (4,-7) and (9,1)

bulgar [2K]

Answer:

8/5

Step-by-step explanation:

We can use the formula for finding slope for this: $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$\frac{1 - (-7)}{9 - 4}$

$\frac{8}{5}$

The answer would be 8/5

Your friend attempted to factor an expression as shown. Find the error in your friends work. Then factor the expression correctl

loris [4]

Answer:

Third step is incorrect. The correct factored form is (x-1)(2x-5).

Step-by-step explanation:

The given expression is

$2x^2-7x+5$

We need to find the factored form of this expression.

Step 1: Given

$2x^2-7x+5$

Step 2: Splitting the middle term method, the middle term can be written as (-5x-2x).

$2x^2-5x-2x+5$

$(2x^2-5x)+(-2x+5)$

Step 3: Taking out common factors from each parenthesis.

$x(2x-5)-1(2x-5)$

Step 4: Taking out common factors.

$(x-1)(2x-5)$

Therefore, the third step is incorrect. The correct factored form is (x-1)(2x-5).

What is the remainder when 599 is divided by 9?

Schach [20]

$599=540+59=540+54+5=60(9)+6(9)+5$
$\implies\dfrac{599}9=66+\dfrac59$

so the remainder is 5.
