B. 3 because 12+ 9 = 21 then (4 + 3)x = 7x do you divide 7 by 21 and it’s x = 3 (hope this makes sense)

Answer: B(3)

Explanation: 12+9=21 so since 4+3 only equals 7, you plug in x as 3... since 7x3 is 21 that helps make the statement true bc both equations are equal.

Answer:

Following are the solution to the given question.

Step-by-step explanation:

Please find the graph file and its solution in the attachment.

$4x-15=3x+28\\\\4x-3x=28+15\\\\x=43\\\\$

Similarly:

$3y+5=2y+50\\\\3y-2y=-5+50\\\\y=45\\\\$

For point 1: $\to KR=4x-15= 4\times 43-15=172-15=157$

For point 2: $\to BR=2y+50= 2\times 43+50=86+50=136$

For point 3: $\to BE=KR=157$

For point 4: $\to Kf=BR=130$

For point 5: $\to ERK=KFB=180^{\circ} -\angle B-\angle ERB = 180^{\circ}-92^{\circ}-18^{\circ}=70^{\circ}$

If f(x) = 4x – 8 and g(x) = 5x + 6, find (f - g)(x).

Fofino [41]

Answer:

- x - 14

Step-by-step explanation:

(f - g)(x) = f(x) - g(x)

f(x) - g(x) = 4x - 8 - (5x + 6) = 4x - 8 - 5x - 6 ← collect like terms

(f - g)(x) = - x - 14
