Because of the open circle at -7, the inequality uses a Less-than or Greater-than sign.

<h3>What are Equations?</h3>

A mathematical statement that has a "equal to" symbol between two expressions with equal values is called an equation. as in 3x + 5 Equals 15, for instance.

Equations come in a variety of forms, including linear, quadratic, cubic, and others.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

We have LHS = RHS (left hand side = right hand side) in every mathematical equation. To determine the value of an unknown variable that represents an unknown quantity, equations can be solved. The statement is not an equation if there is no "equal to" sign in it.

Hence, Because of the open circle at -7, the inequality uses a Less-than or Greater-than sign.

Jessica's Furniture Store buys a couch at a wholesale price of \$113.00$113.00dollar sign, 113, point, 00.

andrew-mc [135]

Answer:

$50.85

Step by step explanation:

We have been given that Jessica's Furniture Store buys a couch at a wholesale price of $113.00 and the markup rate at Jessica's Furniture Store is 45%.

We can find mark-up for the couch by finding 45% of 113.

$\text{Mark-up}=113\times \frac{45}{100}$

$\text{Mark-up}=113\times 0.45$

$\text{Mark-up}=50.85$

Therefore, mark-up for the couch will be $50.85.

Based on only the information given in the diagram, which congruence postulates or theorems can be given as reasons why triangle

Lapatulllka [165]

Let's go through the choices.

A. HL, hypotenuse-leg. Yes we have a right triangle with congruent hypotenuse and leg which gives us congruent triangles, CHECK

B. HA, hypotenuse actute. Yes we have a right triangle witha congruent hypotenuse and acute angle, so congruent triangles, CHECK.

C. LL. leg leg. We don't know HL=PE so we can't use this theorem here. NO.

D. SAS, side angle side. For this one we first have to prove angle HEL is congruent to angle PME which is easily done with the Triangle Angle theorem (two congruent angles means three congruent angles) and then we can use SAS because then we have congruent sides and a congruent included angle. This one's a judgement call, I'll say NO because of the two steps.

E. AAS. Angle Angle Side, yes we have two congruent angles and a side. CHECK

F. ASA. Again we need an additional step before we conclude two angles and an included side are congruent. So again a judgement call, we'll go with NO.
