4 0

Answer:

7y + 5z + 10

Step-by-step explanation:

2y + 7z - 2z + 4y + 8 + y + 2

Like terms are terms that have the same variable part.

2y, 4y, y are like terms (remember that y is the same as 1y when you add)

7z, -2z are like terms

8, 2 are like terms

2y + 7z - 2z + 4y + 8 + y + 2 =

= 2y + 4y + y + 7z - 2z + 8 + 2

= 7y + 5z + 10

Westkost [7]

Answer:

Given:

(i) Wendy reduced her daily commute time by 75% by learning how to fly.

(ii) Previously, it took her 'm' minutes to commute.

To find:

(i) Wendy's commute time in minutes after she learned how to fly.

Solution:

Given that earlier it took Wendy 'm' minutes to commute.

After learning how to to fly, the commute time reduced by 75%.

So, time taken now = (100-75)% of previous time

= 25% of 'm' minutes

= \frac{25m}{100}

100

25m

= \frac{m}{4}

4

m

So, the time taken by Wendy now is \frac{m}{4}

4

m

minutes.

How ro turn y + 7 = -5 ( x + 3) into standard form
GuDViN [60]
There are many standard forms
there is ax+by=z or slope-intercept form which is y=mx+b
I will do both
first distribute the -5
y+7=-5x-15
add 5x to both sides
5x+y+7=-15
subtract 7 from both sides
5x+y=-22


or slope-intercpt form
distribute -5
y+7=-5x-15
subtract 7 from both sides
y=-5x-22
