Let's solve your equation step-by-step.

7y+5−3y+1=2y+2

Step 1: Simplify both sides of the equation.

7y+5−3y+1=2y+2

Simplify: (Show steps)

4y+6=2y+2

Step 2: Subtract 2y from both sides.

4y+6−2y=2y+2−2y

2y+6=2

Step 3: Subtract 6 from both sides.

2y+6−6=2−6

2y=−4

Step 4: Divide both sides by 2.

2y/2=−4/2

y=−2

Answer:

y=−2

When the polynomial is written in standard form, what are the values of the leading coefficeient and the constant? 5x + 2 - 3x2

Elina [12.6K]

Answer:

The leading coefficient is -3

The constant is 2

Step-by-step explanation:

The standard form of a polynomial is the descending order, that means that it must be written according from its higher power, down straight to the coefficient with no variable.

Hence, the leading coefficient is the one that is next to the highest exponent of the polynomial, in this case: =3x2.

The second term is 5x

And the last is 2. the constant

Shay created the table below to graph the equation r-3-sin theta (rounded to the hundredths place). Analyze the table. Did Shay

monitta

Answer:

B is false

Step-by-step explanation:

Let's check Shay's table:

if $\theta=0,$ then $r=3-\sin 0=3-0=3$ (true);
if $\theta =\dfrac{\pi}{6},$ then $r=3-\sin \dfrac{\pi}{6}=3-\dfrac{1}{2}=2.5$ (true);
if $\theta = \dfrac{\pi}{4},$ then $r=3-\sin \dfrac{\pi}{4}=3-\dfrac{\sqrt{2}}{2}\approx2.29$ (true);
if $\theta=\dfrac{\pi}{3},$ then $r=3-\sin \dfrac{\pi}{3}=3-\dfrac{\sqrt{3}}{2}\approx 2.13$ (false);
if $\theta =\dfrac{\pi}{2},$ then $r=3-\sin \dfrac{\pi}{2}=3-1=2$ (true).

What is the value of the function at x=−2?

kogti [31]

So for this problem, the x-axis is the horizontal line in the center.

Go to where -2 is on the x-axis as shown. Use your finger to trace along since that's usually helpful in finding the point.

Move your finger from -2 on the x-axis to where the solid black line is. On the right side of that, you can see that the y-axis holds the number 2 which is what the y equals for this solid line.

Therefore, the answer should be c.) y = 2
