Answer:

c=|x-7|

Step-by-step explanation:

The values of "c" for which the equation |x - 7| = c has no solution are any values of "c" that are less than or equal to zero.

The equation |x - 7| = c represents the absolute value of the difference between x and 7, which is equal to the constant "c."

For an absolute value equation like this, there are two cases to consider:

When (x - 7) is nonnegative (or zero): In this case, the absolute value of (x - 7) is just (x - 7) itself. So the equation becomes:

x - 7 = c

When (x - 7) is negative: In this case, the absolute value of (x - 7) is the negative of (x - 7). So the equation becomes:

-(x - 7) = c

-x + 7 = c

Now let's analyze these cases to determine the values of "c" for which the equation has no solution:

Case 1: x - 7 = c

If "c" is positive, then we can solve for "x":

x = c + 7

This solution is valid for all values of "c" because it provides a real solution for any positive "c."

Case 2: -x + 7 = c

If "c" is positive, we can solve for "x":

x = 7 - c

This solution is valid for all values of "c" because it provides a real solution for any positive "c." positive value of "c" will have a valid solution. However, if "c" is negative or zero, then there is no real value of "x" that satisfies the equation. This is because the absolute value of a real number is always nonnegative, so if "c" is negative or zero, there is no real value of "x" that can make |x - 7| equal to a negative or zero "c."

Answer:

n = -13

Step-by-step explanation:

√10 - 3n = 7 ⇔

⇔ 10 - 3n = 49 ⇔ We need to remove the square root. Ex: √n = 2 ⇔ n = 2²

⇔  -3n = 49 - 10 ⇔
⇔ -3n = 39 ⇔
⇔ n = [tex]\frac{39}{-3}[/tex] = -13 (as -3 changes members, as it was multiplying, it now divides, conversion).

Answer:

height = 14.2 m , base = 7.1 m

Step-by-step explanation:

let the base be b then height h = 2b

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh

Here A = 50 , then

[tex]\frac{1}{2}[/tex] × b × 2b = 50

b² = 50 ( take square root of both sides )

b = [tex]\sqrt{50}[/tex] ≈ 7.1 ( to the nearest tenth )

Then base = 7.1 m and height = 2 × 7.1 = 14.2 m

Answer:

Well, first you'll have to do P (perimeter) = 2(a + b)

So: P= 2(68/15 + 32/5)*

P = 2(164/15)

Then, do the equation:

Inequalities are used to represent unequal expressions

The solution to the inequality is: [tex]x > -3[/tex]

The inequality is given as:

60>5(6-2x)

Rewrite the inequality properly as:

[tex]60>5(6-2x)[/tex]

Divide both sides of the inequality by 5

[tex]12>6-2x[/tex]

Subtract 6 from both sides of the inequality

[tex]6>-2x[/tex]

Divide both sides of the inequality by -2

[tex]-3

Given that ACE is an isosceles triangle, the measure of ∠CDB is: 55°

The two base angles of any isosceles triangle are always congruent to each other.

Therefore:

m∠CBD = m∠CDB

m∠CBD = 180° - 125° (supplementary angles)

m∠CBD = 55°

Therefore:

m∠CBD = m∠CDB = 55°

In summary, given that ACE is an isosceles triangle, the measure of ∠CDB is: 55°
