Use the graph to find the factorization of x^2 - 7x + 12.

harkovskaia [24]

Answer:(x-3)(x-4)

Step-by-step explanation:Basically, the intercepts of the graph, 3 and 4, are when the graph is equal to zero, which is why is (x-3)(x-4) and not (x+3)(x+4).

2. Write your own equation in slope intercept form. Identify the slope, m, and y-intercept, b.

liberstina [14]

Slope intercept form
y = mx + b:

10 = 7x + 3

y = 10
slope (m) = 7
b = 3

standard form:
Ax + By + C:

7x + 10y + 3

A = 7
B = 10
C = 3

hope this helps

7.4x + 4.1(2x − 4) = −2.3(x − 6) − 21.6

loris [4]

Answer:

x = $\frac{86}{179}$

Step-by-step explanation:

7.4x + 4.1(2x − 4) = −2.3(x − 6) − 21.6

Multiply both sides by 10:

7.4x×10+4.1(2x-4)×10=-2.3(x-6)×10-21.6×10

Refine:

74x+41(2x-4)=-23(x-6)-216

Distributive Property:

74x+82x-164=-23(x-6)-216

Combine like terms:

156x-164=-23(x-6)-216

Distributive Property:

156x-164=-23x+138-216

Combine like terms:

156x-164=-23x-78

Add 164 to both sides:

156x-164+164=-23x-78+164

Simplify:

156x=-23x+86

Add 23x to both sides:

156x+23x=-23x+86+23x

Simplify:

179x=86

Divide both sides by 179:

$\frac{179x}{179}$ = $\frac{86}{179}$

Simplify:

x = $\frac{86}{179}$
