Answer:

12x +2

Step-by-step explanation:

f(x) = 8x – 3; g(x) = 4x + 5

(f+g)(x) = 8x – 3 + 4x + 5

Combine like terms

= 12x +2

8x-3y+24=48 in slope intercept form

disa [49]

Hello!

Slope-intercept form is written as y = mx + b. In this form, m is the slope and b is the y-intercept. Remember to use SADMEP when solving algebraic equation. This main goal is to get y by its self.

(SADMEP = subtraction, addition, division, multiplication, exponents, parentheses)

8x - 3y + 24 = 48 (subtract 24 from both sides)

8x - 3y = 24 (subtract 8x from both sides)

-3y = -8x + 24 (divide both sides by 3)

y = 8/3x + -8

Therefore, the final answer is y = 8/3x + -8.

Draw fraction rectangles on dot paper to solve the problems.

juin [17]

Answer:

1) $\frac{7}{20}$

2) $1\frac{1}{12}$

3) $\frac{7}{8}$

Step-by-step explanation:

1) Given problem,

$\frac{3}{5}-\frac{1}{4}$

LCM(5,4) = 20,

$\frac{3}{5}=\frac{3\times 4}{5\times 4}=\frac{12}{20}$

$\frac{1}{4}=\frac{1\times 5}{4\times 5}=\frac{5}{20}$

$\implies \frac{3}{5}-\frac{1}{4}=\frac{12}{20}-\frac{5}{20}=\frac{7}{20}$

2) Given problem,

$\frac{5}{6}+\frac{1}{4}$

LCM(6, 4) = 12,

$\frac{5}{6}=\frac{5\times 2}{6\times 2}=\frac{10}{12}$

$\frac{1}{4}=\frac{1\times 3}{4\times 3}=\frac{3}{12}$

$\implies \frac{5}{6}+\frac{1}{4}=\frac{10}{12}+\frac{3}{12}=\frac{13}{12}=1\frac{1}{12}$

3) ∵ Pizza ate by Manny = $\frac{1}{4}$

Pizza ate by Frank = $\farc{5}{8}$

∴ Total pizza eaten = $\frac{1}{4}+\frac{5}{8}$

LCM(4, 8) = 8,

$\frac{1}{4}=\frac{2}{8}$

Thus, total pizza eaten = $\frac{2}{8}+\frac{5}{8}=\frac{7}{8}$
