Given:

The expression is

9-3\div \dfrac{1}{3}+1

To find:

The value of given expression.

Solution:

We have,

9-3\div \dfrac{1}{3}+1

BODMAS : Bracket, Order, Division, Multiplication, Addition, and Subtraction.

Using BODMAS, first we need to perform division in the given expression.

=9-(3\div \dfrac{1}{3})+1

=9-(3\times 3)+1

=9-9+1

Now, apply addition.

=(9+1)-9

=10-9

Now, apply subtraction.

=1

Therefore, the value of given expression is 1.

What is the measurement of Angle JKL? *
nataly862011 [7]

Answer:

Option (1)

Step-by-step explanation:

From the triangles given in the picture,

Since, JK ≅ KL [Given]

JM ≅ ML [Given]

KM ≅ KM [Reflexive property of congruence]

ΔJMK ≅ ΔLMK [SSS property of congruence]

Therefore, ∠JKM ≅ ∠LKM [CPCTC]

(2x + 5) = (3x - 6)

3x - 2x = 5 + 6

x = 11

m∠JKL = m∠JKM + m∠LKM

            = (2x + 5) + (3x - 6)

            = 5x - 1

            = 5(11) - 1

             = 54

Option (1) will be the answer.

Answer:

g(x) = 1: 0

g(-2) = -3

Step-by-step explanation:

Just by looking at the graph, at the origin, <em>x</em><em> </em>is 0 and g(x)<em> </em>is 1. Now, look at where <em>x</em><em> </em>is -2. Below that, you see where g(-2) is because -2 REPLACED <em>x</em><em>.</em>
