Answer:

We conclude that the algebraic expression 9r+2 can be verbally expressed in many ways such as:

Two more than 9 times a number, r.

9 times a number, r, increase by 2.

Step-by-step explanation:

Given the algebraic expression

9r+2

We know that 9r is the product of 9 and 3.

Thus,

9r+2 can be verbally expressed in many ways such as:

Two more than 9 times a number, r.

or it can be also verbally expressed such as:

9 times a number, r, increase by 2.

Therefore, we conclude that the algebraic expression 9r+2 can be verbally expressed in many ways such as:

Two more than 9 times a number, r.

9 times a number, r, increase by 2.

Quadrilateral JKLM is graphed with vertices at J(-2,2), K(-1,-5), L(4,0), and M(3,7).

AveGali [126]

Answer:

<u>Question (a)</u>

Midpoint of a line segment:

$M=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)$

Given:

J = (-2, 2)
L = (4, 0)

$\implies \textsf{midpoint of }JL=\left(\dfrac{-2+4}{2},\dfrac{2+0}{2}\right)=(1,1)$

Given:

M = (3, 7)
K = (-1, -5)

$\implies \textsf{midpoint of }MK=\left(\dfrac{3-1}{2},\dfrac{7-5}{2}\right)=(1, 1)$

<u>Question (b)</u>

Find slopes (gradients) of JL and MK then compare. If the product of the slopes of JL and MK equal -1, then JL and MK are perpendicular.

$\textsf{slope }m=\dfrac{y_2-y_1}{x_2-x_1}$

Given:

J = (-2, 2)
L = (4, 0)

$\implies \textsf{slope of }JL=\dfrac{0-2}{4+2}=-\dfrac13$

Given:

M = (3, 7)
K = (-1, -5)

$\implies \textsf{slope of }MK=\dfrac{-5-7}{-1-3}=3$

$\textsf{slope of }JL \times \textsf{slope of }MK=-\dfrac13 \times3=-1$

Hence segments JL and MK are perpendicular

Solve b 4b+5=1+5b what is b

Leto [7]

Answer: b=4

Step-by-step explanation: Let's solve your equation step-by-step.

4b+5=1+5b

Step 1: Simplify both sides of the equation.

4b+5=5b+1

Step 2: Subtract 5b from both sides.

4b+5−5b=5b+1−5b

−b+5=1

Step 3: Subtract 5 from both sides.

−b+5−5=1−5

−b=−4

Step 4: Divide both sides by -1.

−b

−1

−4

−1

b=4
