Answer:

x= 1/8

Step-by-step explanation:

7-14x=2x-5

-16x=-2

\frac{-16}{-16} =\frac{-2}{-16} \\=\frac{1}{8}

Given the circle below secant kjI and tangent hi find the length of hi round to the nearest tenth if necessary.
garik1379 [7]

The length of the segment HI in the figure is 32.9

<h3>How to determine the length HI?</h3>

To do this, we make use of the following secant-tangent equation:

HI² = KI * JI

From the figure, we have:

KI = 21 + 24 = 45

JI = 24

So, we have:

HI² = 45 * 24

Evaluate the product

HI² = 1080

Take the square root of both sides

HI = 32.9

Hence, the length of the segment HI is 32.9

Pleaseeeee help me. i really need it.
deff fn [24]

comparing the relation given

thus y= -2x +1 to the general equation of a line

where y= mx + c

where m is the gradient and c is the intercept on the y-axis.

from the question, the gradient is -2 and since the line is perpendicular, the gradient is given as

\frac{ - 1}{m}

so substituting the value of m in to the equation

\frac{ - 1}{ - 2}

=

\frac{1}{2}

as the gradient

equation of line is given by

y - y1 = m( x-x1)

from the question y1= -2 and x1=1

substitute them

y-(-2) = 1/2 (x -1)

y+2 =1/2 (x-1)

multiplying through by 2

2 (y+2) = x-1

2y +4 = x-1

2y =x-1-4

2y =x-5

x -2y -5 = 0

therefore the equation for the line is x-2y -5=0

If two points on line l above have coordinates (0, A) and (2, −3), and the slope of the line is A, then what is the value of A?
Vlada [557]

Answer:

A = -1

So, option (B) is the correct answer.

Step-by-step explanation:

The two points on line have coordinates: p (x₁, y₁) = (0, A) and q(x₂, y₂) = (2 , -3)

Slope of line = A

Slope of line = \frac{y_{2} - y_{1}}{x_{2} -x_{1}}

Now since the slope of line is A  and its has two coordinates (0, A) and (2 , -3), ∴

A = \frac{y_{2} - y_{1}}{x_{2} -x_{1}}

A = \frac{-3 - A}{2 - 0}

2A = -3 - A

2A + A = -3

3A = -3

A = -1

So, option (B) is the correct answer.
