MArishka [77]

Answer:To find the x-intercept, substitute in 00 for yy and solve for xx. .

x-intercept(s): (1,0),(−4,0)(1,0),(-4,0)

y-intercept(s): (0,−4)

Step-by-step explanation:Graph the parabola using the direction, vertex, focus, and axis of symmetry.

Direction: Opens Up

Vertex: (−3/2,−25/4)(-3/2,-25/4)

Focus: (−3/2,−6)(-3/2,-6)

Axis of Symmetry: x=−3/2 x=-32

Directrix: y=−13/2 y=40−3−4−32−254−1−60−4

Solve for X...........

blsea [12.9K]

Answer: First Choice. no solution

Step-by-step explanation:

Given

5 (x + 1) ≤ 5x + 3

Expand parentheses and apply the distributive property

5x + 5 ≤ 5x + 3

Subtract 5x on both sides

5x + 5 - 5x ≤ 5x + 3 - 5x

5 ≤ 3

5 ≤ 3 is not true, therefore, there is no solution.

Hope this helps!! :)

Which terms and 45p4q have a GCF of 9p3? Select two options.

fgiga [73]

Answer:

$18p^3r$

$63p^3$

Step-by-step explanation:

The prime factorization of $45p^4q$ is

$45p^4q=3^2\times 5\times p^4\times q$

The prime factorization of $18p^3r$ is $18p^3r=2\times 3^2\times p^3\times r$

The GCF of $45p^4q$ and $18p^3r$ is $3^2\times p^3=9p^3$

The prime factorization of $27p^4q$ is $3^3\times p^4\times q$

The GCF of $45p^4q$ and $27p^4q$ is $3^2\times p^4\times q=9p^4q$

The prime factorization of $36p^3q^6$ is $3^2\times \times 2^2p^3q^6$

The GCF of $45p^4q$ and $36p^3q^6$ is $3^2\times p^3\times q=9p^3q$

The prime factorization of $63p^3$ is $3^2\times 7\times p^3$ .

The GCF of $45p^4q$ and $63p^3$ is $3^2\times p^3=9p^3$

The prime factorization of $72p^3q^6$ is $2^3\times 3^2p^3q^6$

The GCF of $45p^4q$ and $72p^3q^6$ is $3^2\times p^3\times q=9p^3q$
