2x+2y find the slope and y intercept

Answers

Answer 1

Answer: Equations can be graphed.
Expressions can't.
(2x + 2y) is not an equation.
It can't be graphed.
It has no slope, and no intercept.
It's just an expression that stands for a number.
We can't find the number until we know the values of 'x' and 'y'.

If you told us a number that's equal to (2x + 2y), THEN we'd have
an equation, which could be graphed, and it would have a slope
and an intercept.

Triangle ABC is similar to triangle QRS by the AA Similarity Postulate.Also, m∠A = 45° and m∠S = 75°.

What is m∠B?

_________ °

Answers

Answer:

Measure of ∠B is 60°

Step-by-step explanation:

Given triangle ABC is similar to triangle QRS.

m∠A = 45° and m∠S = 75°

we have to find the measure of ∠B.

As triangles are similar then corresponding angles are congruent.

⇒ ∠A≅∠Q, ∠B≅∠R, ∠C≅∠S

hence, m∠C=m∠S=75°

By angle sum property

m∠A+m∠B+m∠C=180°

⇒ 45°+m∠B+75°=180°

⇒ m∠B+120°=180°

⇒ m∠B=60°

hence, measure of ∠B is 60°

Angle B is 60 degrees

The length of my desk is 46 cm how many centimetres short of a metre is the desk 40cm 50cm 30cm 54cm

Answers

A metre = 100 centimeters.

If you say your desk measures 46cm:

Which algebraic expression represents the phrase “the quotient of negative eight and the sum of a number and three”?

Answers

Quotient: division

Negative 8: -8

Sum of a number: let the unknown number be represented by x

And Three: x + 3

So, the quotient (division) of -8 and x+3

-8 ÷ x + 3

What's 4/5×5/8 please I really need help with this one

Answers

$(4)/(5)$ × $(5)/(8)$

First, apply this rule: $(a)/(b)$ × $(c)/(d)$ = $(ac)/(bd)$ / Your problem should look like: $(4x5)/(5x8)$
Second, simplify 4 × 5 to 20. / Your problem should look like: $(20)/(5x8)$
Third, simplify 5 × 8 to 40. / Your problem should look like: $(20)/(40)$
Fourth, simplify. / Your problem should look like: $(1)/(2)$

Answer as fraction: $(1)/(2)$
Answer as decimal: 0.5

$(4)/(5) * (5)/(8) = (4:2)/(5:5)* (5:5)/(8:2) \n\n~~~~~~~=2* (1)/(4) \n\n~~~~~~~= (2)/(4)$
