For what value of a does the equation ax^2−3x−5=0 have 1 as one of its roots?

1 answer:

5 0

Answer: When a = 8, one of the roots of the equation will be 1.

To solve this problem, you could graph the equation with a 1 in the place of the a on a graphing calculator (there are some online).

Then, just keep changing the a value until the graph crosses the x-axis at 1. When, you enter an a value of 8, it will have a root of 1.

Explanation:

First you had to square from both sides of equation form.

$(\sqrt{x-6+2})^2=6^2$

Then you expanded form.

$(\sqrt{x-6+2})^2=x-4$

$x-4=36$

$6^2=6*6=36$

Solve by equation form.

$x-4=36$

Add by four from both sides of equation form.

$x-4+4=36+4$

Simplify.

$x=40$

Verified solutions.

$x=40 \boxed{TRUE}$

Final answer: $\boxed{x=40}$

Hope this helps!

calculate the scale factor of abc to def enter answer as a whole number or as a fraction into lowest terms

SVETLANKA909090 [29]

Answer:

Scale is 1/6

Step-by-step explanation:

Since all sides and angles are identical these are congruent triangles

3 ways to solve:

Scale Factor = DE / AB = 12/72 = 1/6

Scale Factor = DF/AC = 7/42 = 1/6

Scale Factor = EF/CB = 11/66 = 1/6
