You didn't list any choices.

anyway here's the solution solved with the quadratic formula:
a = 6 b=-9 c=22
The solution would be:
x =[--9 +-square root (81 - 4*6*22)] / 12
x = [9 +- square root (81 -528)] / 12
x = [9 +- square root (-447)] / 12
x = .75 (+- 1.7619 i)

Given the formula below, solve for x.

san4es73 [151]

Answer:

Option (C)

Step-by-step explanation:

Given formula of a line passing through $(x_1, y_1)$ and slope 'm' is,

$y-y_1=m(x-x_1)$

Further solving this equation,

$y-y_1=mx-mx_1$ [By distributive property]

$y-y_1+mx_1=(mx-mx_1)+mx_1$ [By adding $mx_1$ on both the sides]

$y-y_1+mx_1=mx$

$\frac{y-y_1-mx_1}{m}=\frac{mx}{m}$ [Divide the equation by m]

$\frac{y-y_1}{m}-x_1=x$

Therefore, Option (C) will be the answer.

Suppose water flows from a shower at a rate of 0.35 cubic feet per minute. do you use more water by taking a 15-minute shower or

timurjin [86]

Unit conversion is a way of converting some common units into another without changing their real value. The option in which more water will be used is by filling a bathtub.

<h3>Units conversion</h3>

Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.

Given water flows from a shower at a rate of 0.35 cubic feet per minute. Therefore, the water that will be used in the shower,

Water used in Shower = 0.35 × 15 = 5.25 cubic feets

Water used in bathtub = 0.5 yards³ = 13.5 cubic feets

Hence, the option in which more water will be used is by filling a bathtub.

If two sides of a triangle are 9cm and 15cm in length, which could be the measure of the third side?

aliya0001 [1]

Answer:

The two sides of the triangle are 9 cm and 15 cm. Let the length of the third side is x. According to triangle inequalities, in a triangle sum of the two sides is must be greater than the third side. So, the length of the third side is less than 24 cm.

The true statement is (c) Yes, the sequence is an isometry transformation because it contains only rigid transformation

<h3>How to determine the type of transformation?</h3>

The coordinates are given as:

A = (1, 2), B = (3, 2) and C = (2, 7)

D = (3, -6), E = (5, -6) and F = (4, -1)

Calculate the lengths of pre-image and the image using

d = √(x2 - x1)² + (y2 - y1)²

So, we have:

AB = √(1 - 3)² + (2 - 2)² = 2

DE = √(3 - 5)² + (-6 + 6)² = 2

AB and DE are congruent

BC = √(3 - 2)² + (2 - 7)² = √26

EF = √(5 - 4)² + (-6 + 1)² = √26

BC and EF are congruent

CA = √(2 - 1)² + (7 - 2)² = √26

FD = √(4 - 3)² + (-1 + 6)² = √26

CA and FD are congruent

Because the corresponding sides are congruent, then the transformation is an isometry transformation.

This is so because isometry transformation do not alter side lengths and angles

Hence, the true statement is (c) Yes, the sequence is an isometry transformation because it contains only rigid transformation
