Mathematics
1 answer:
alexandr1967 [171]3 years ago
4 0

Answer:

The answer is 2.  x = 2

Step-by-step explanation:

2 x 2 + 1x = 6

2 x 2= 4

4 + 1x = 6

4 - 4 = 0

6 - 4 = 2

1x = 2

1x / 1 = 1 <--- This gets cancled out but leave the x.

2/ 1 = 2

x = 2

Does anyone know what the slope equation is for this graph. PLz explain if you can. Ty!
yKpoI14uk [10]
<h3>Answer:   y = (-3/2)x+3</h3>

In decimal form, this is y = -1.5x+3

=========================================

Explanation:

Start at (0,3). Move three units down and two units to the right to get to (2,0)

slope = rise/run

slope = -3/2

rise = -3 = go 3 units down

run = 2 = go 2 units to the right

--------------------------

We could use the two points (0,3) and (2,0) in the slope formula below

m = (y2-y1)/(x2-x1)

m = (0-3)/(2-0)

m = -3/2

So this is another way to see the slope is -3/2

--------------------------

The y intercept is where the graph crosses the vertical y axis. In this case, it's at 3. So b = 3

Using m = -3/2 and b = 3, we go from y = mx+b to y = (-3/2)x+3 which is equivalent to y = -1.5x+3

What value of x satisfies this equation (5x + 20) = 2
FrozenT [24]

Answer:

x equals -3.6

Step-by-step explanation:

5 something +20 is supposed to be 2, so you take the two off of the 20 and get 18, then divide the 18 by 5 and you'll get 3,6 and logically since it needs to be negative you need the minus before it.

Ursula and Velda live 4 km apart. They leave their homes at the same time, walking towards each other. If Ursula walks at a rate
vladimir2022 [97]

Answer: 250 m

Step-by-step explanation:

Given

Distance between Ursula and Velda house is 4 km or 4000 m

Ursula walks at the rate of 400\ m/h\ or\ \frac{20}{3}\ m/min

Velda walks at the rate of 600\ m/h\ or\ 10\ m/min

Time taken by them to cover 4000 m is

\Rightarrow \dfrac{4000}{400+600}=4\ h\ or\ 240\ min

Distance covered by them 15 min before they meet

Ursula =\frac{20}{3}\times 225=1500\ m

Velda =10\times 225=2250\ m

The total length covered by them is =1500+2250=3750\ m

They are 4000-3750=250\ m apart before they meet
