3n-18-2n+10+n

Answers

Answer 1

Answer:

Assuming that you're being asked to simplify the expression. If you are, then the answer is 2n - 8

Step-by-step explanation:

Answer 2
Simplified that is 2n -8

This is because the n terms:
3n -2n +n = 2n
And the integer terms:
-18+10 = -8
Together this is 2n-8

Factor this polynomial.
-3x² - 6x-2

Answers

Answer:

Doesn't factor

Step-by-step explanation:

We have a polynomial and are asked to factor it.

A rule I like to follow when factoring polynomials is what two numbers multiply to equal c (in this case -2) and add up to b (in this case -6x).

Since no two numbers are eligible to do this, therefore this polynomial is unfactorable.

Which quadratic function in vertex form can be represented by the graph that has a vertex at (3, -7) and passes through the point (1, -10)?
I really need the answer QUICK please​

Answers

Answer:

Answer is D

Step-by-step explanation:

(3,-7) and (1,-10) belong toD Variant

The required function is [tex]y=-\frac{3}{4}(x-3)^2-7[/tex] , so the correct option is D.

Important information:

Vertex = (3,-7)Other point = (1,-10)Quadratic function:

The vertex form of a quadratic function is:

[tex]y=a(x-h)^2+k[/tex]

Where, [tex]a[/tex] is constant and [tex](h,k)[/tex] is vertex.

Substitute [tex]h=3,k=-7[/tex].

[tex]y=a(x-3)^2-7[/tex]        ...(i)

Graph passes through the point (1, -10). Substitute [tex]x=1,y=-10[/tex] in (i).

[tex]-10=a(1-3)^2-7[/tex]

[tex]-10+7=4a[/tex]

[tex]-3=4a[/tex]

[tex]\dfrac{-3}{4}=a[/tex]

Substitute [tex]a=-\dfrac{3}{4}[/tex] in (i).

[tex]y=-\frac{3}{4}(x-3)^2-7[/tex]

Therefore, the correct option is D.

A total of 110 gallons of water can follow through Hose B in minutes. Which hose has a faster water ow rate, in gallons per minute, and what is that rate?

Answers

Answer:

Hose B

Step-by-step explanation:

Charles needs to fill a large fish tank with water using a hose. he has two hoses from which to choose. Water flows through each hose at a constant rate. The graph below shows the amount of water, in gallons , that flows through holes A based on the number of minutes used. A total of 110 gallons of water can flow through Hose B in 10 minutes. Which hose has a faster water rate, in gallons per minute, and what is that rate?

Solution:

The equation of a linear function is:

y = mx + b

where m is the rate of change and b is the initial value of y.

The equation of a line passing through two points [tex](x_1,y_1)\ and\ (x_2,y_2)[/tex] is given by:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)[/tex]

Let y represent the amount of water in gallons and let x represent the time in minutes.

For hose A, we can see that the graph passes through the point (0, 0) and (2, 12). Hence:

[tex]y-0=\frac{12-0}{2-0}(x-0) \\\\y=6x[/tex]

Therefore hose A has a flow rate of 6 gallons per minute.

110 gallons of water flow through hose B in 10 minutes. Therefore:

Flow rate of hose B = 110 gallons / 10 minutes = 11 gallons per minute

Therefore hose B has a higher flow rate

(8-4)x4 = [tex]4^{2}[/tex]

[tex]2^{2} +2^{2}[/tex] = 8

Step-by-step explanation:

To solve the first one simplify the exponents and then divide them; [tex]4^{2}[/tex] equals 16 and [tex]2^{2}[/tex] equals 4. Therefore the expression is 16/4, which equals 4.

Follow PEMDAS to solve the next one. First paratheses, (8-4) equals 4. Then, multiply by 4. 4x4 can also be rewritten as [tex]4^{2}[/tex].

Simplify the exponents to solve the last expression. [tex]2^{2}[/tex] is 4, so the expression is equal to 4+4, which is 8.

Answers

Answer:

$5318

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 4%/100 = 0.04 per year,

then, solving our equation

I = 2650 × 0.04 × 3 = 318

I = $ 318.00

The simple interest accumulated

on a principal of $ 2,650.00

at a rate of 4% per year

for 3 years is $ 318.00.

Find the missing angle:
40°
?

Answers

Answer:

50

Step-by-step explanation:

180 − ( 90 + 40 )

180 − 130

50

50 degrees is the missing angle in the triangle

The given triangle is right angle triangle

One angle is 90 degrees and the other angle in the triangle is 40 degrees

We have to find the missing angle in the triangle

By angle sum property the sum of the three angles is 180 degrees in the right triangle

Let x be the missing angle

90+40+x=180

130+x=180

Subtract 130 from both sides

x=180-130

x=50 degrees

Hence, the missing angle in the triangle is 50 degrees

The vertices of parallelogram DEFG are E(-1,4) F(5,6) and G (8,0). Find the coordinates of D

Answers

Answer:

The coordinates of D are (2,-2)

Step-by-step explanation:

The coordinates of point D are (2,-2)

The coordinates of the parallelogram are given as:

E(-1,4),  F(5,6) and G (8,0)

For the coordinates to represent a parallelogram, the following must be true

[tex]x_D - x_E = x_G - x_F[/tex]

[tex]y_D - y_E = y_G - y_F[/tex]

So, the equations become

[tex]x_D -(-1) =8-5[/tex] and

[tex]y_D -4 =0-6[/tex]

Solve for x and y in the above equations

[tex]x_D -(-1) =8-5[/tex]

[tex]x_D +1 = 3[/tex]

[tex]x_D = 3-1[/tex]

[tex]x_D = 2[/tex]

[tex]y_D -4 =0-6[/tex]

[tex]y_D - 4 = -6[/tex]

[tex]y_D = 4-6[/tex]

[tex]y_D =-2[/tex]

Hence, the coordinates of point D are (2,-2)
