Suppose PR = 54, solve for QR 4x-1 3x-1 P R

Answer:

QR = 23

Step-by-step explanation:

P, A, and R are collinear.

PR = 54

PQ = 4x - 1

QR = 3x - 1

To solve for the numerical length of PR, let's generate an equation to find the value of x.

According to the segment addition postulate:

PQ + QR = PR

(4x - 1) + (3x - 1) = 54 (substitution)

Solve for x

4x - 1 + 3x - 1 = 54

Combine like terms

4x + 3x - 1 - 1 = 54

7x - 2 = 54

Add 2 to both sides

7x - 2 + 2 = 54 + 2

7x = 56

Divide both sides by 7

\frac{7x}{7} = \frac{56}{7}

x = 8

QR = 3x - 1

Plug in the value of x into the equation

QR = 3(8) - 1 = 24 - 1

QR = 23

Answer:

(x + 5)**2 + (y + 2)**2 = 25

Step-by-step explanation:

We know that the general equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius. The graph shows the center at (-5, -2), and the radius of 5. So plugging this in

(x - -5)**2 + (y - - 2)**2 = 5**2

(x + 5)**2 + (y + 2)**2 = 25

Solve for x: -5/6x= -10/3 x=?
k0ka [10]

Answer:

Solve for x: -5/6x= -10/3 x=?

x = 1/4

Step-by-step explanation:

from the equation ,Solve for x: -5/6x= -10/3 , to solve for x  we will first cross multiply

we have; -15= -60x

divide both sides by -60

-15/-60 = -60x/-60

x = 15/60 ( the minus will cancel out)

x = 1/4

check for your answer  by putting 1/4 where you see x

i.e -5/6(1/4) = -10/3

-5 × 2/3 = -10/3

-10/3 = -10/3......... proved!!

What is the slope of the line given by the equation y = -3x?
s2008m [1.1K]
The answer to this question would be B, -3. The reason for this is because when you have an equation in slope intercept form, it would be y = mx + b. In this case your b is equal to 0 so you have only y = mx. The variable m represents the slope, which is in this case, equal to -3. Hope this helps. Please rate, leave a thanks, and mark a brainiest answer. (Not necessarily mine). Thanks, it really helps! :D

Please help I’m really stuck !!
lbvjy [14]

The number in the parenthesis is the X value and they are looking for what the Y value is at that specific X.

So when you look at f(-2), find the Y value where the line crosses.

At X-2, the line crosses Y at -2

At X = 2, the line crosses at Y = 2

At X = 4, the line crosses at Y = 1

The answer is -2,2,1
