Answer

\boxed{ \boxed{ \bold{ \red{ - 4a + 5b}}}}

Step by step explanation

\sf3(a + b) - 2(2a - b) + 4a - 7a

Distribute 3 through the parentheses

⇒\sf3a + 3b - 2(2a - b) + 4a - 7a

Distribute 2 through the parentheses

⇒\sf3a + 3b - 4a + 2b + 4a - 7a

Collect like terms

⇒\sf3a +4a - 4a - 7a + 3b + 2b

Since , two opposites add up to zero, remove them from the expression

⇒\sf3a - 7a + 3b + 2b

⇒\sf - 4a + 5b

Hope I helped!

Best regards!!

Today you will need to look at the following problem and explain what Susan did incorrectly.
lapo4ka [179]

Answer:

see explanation

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

(x - 3)² + (y + 4)² = 36 ← is in standard form

with (h, k) = (3, - 4 ) = centre and r = \sqrt{36} = 6

Susan interpreted the values of h and k incorrectly by using the values - 3 and 4 instead of taking the negative of them.

She also divided 36 by 2 , thus omitting the root of 36

How many solutions does the system have ? 20x - 5y = 5 4x - y = 1
Aleks04 [339]

Answer:

Infinite solutions.

Step-by-step explanation:

Just plug your equation into desmos graphing calculator and it will graph it for you. If it is infinite the two lines will lay on top of one another. If there is only one solution it will be where the two lines intersect. If there are no solutions the two lines will be parallel.
