Answer:
2 7/8
Step-by-step explanation:
Let's convert to common denominator
3/8 = 3/8
2 1/2 = 2 4/8
3/8 + 2 4/8 = 2 7/8

Step-by-step explanation:
7x+42=11(3x+8)−2(13x−1)
Step 1: Simplify both sides of the equation.
7x+42=11(3x+8)−2(13x−1)
7x+42=(11)(3x)+(11)(8)+(−2)(13x)+(−2)(−1)(Distribute)
7x+42=33x+88+−26x+2
7x+42=(33x+−26x)+(88+2)(Combine Like Terms)
7x+42=7x+90
7x+42=7x+90
Step 2: Subtract 7x from both sides.
7x+42−7x=7x+90−7x
42=90
Step 3: Subtract 42 from both sides.
42−42=90−42
0=48
Answer:
The equation of the linear function is y = 3x + 3
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
The rule of the slope is m =
, where
- (x1, y1) and (x2, y2) are two points on the line
∵ A line passes through points (1, 6) and (2, 9)
∴ x1 = 1 ad y1 = 6
∴ x2 = 2 and y2 = 9
→ Use the rule of the slope above to find the slope of the line
∵ m =
=
= 3
∴ m = 3
→ Substitute the value of m in the form of the equation above
∴ y = 3x + b
→ To find b substitute x and y in the equation by the coordinates of any
point on the line
∵ x = 1 and y = 6
∴ 6 = 3 (1) + b
∴ 6 = 3 + b
→ Subtract 3 from both sides
∵ 6 - 3 = 3 - 3 + b
∴ 3 = b
→ Substitute the value of b in the equation above
∴ y = 3x + 3
∴ The equation of the linear function is y = 3x + 3
