find the vertex of the following equation
y= (x+9)^2+8
​

Answer:

x < -1.778 or. r < -1.461

Step-by-step explanation:

-9x + 2 > 18

-9x > 18-2

-9x > 16

x < -(16/9)

x < -1 778

13r + 15 < -4

13r <-4 -15

13r < -19

r < -1.461

Answer:

4

Step-by-step explanation:

3/4(x+8)=9

3/4x+6=9

3/4x=3

x=4

P.S. PLEASE give me Brainliest!

Answer: x = 4

Step-by-step explanation:

Divide both sides by 3/4. When you divide by a fraction, you can also multiply by the reciprocal

[tex]x+8=9*\frac{4}{3}[/tex]

Simplify the fraction

[tex]x+8=\frac{36}{3} \\x+8=12\\[/tex]

Subtract 8 on both sides

x = 4

Answer:

the slope is: Positive

slope is: 1/5

y-intercept: -4

equation is: y = 1/5x - 4

Answer:

Slope: Postive

Slope: 5

Y-Intercept: -4

Equation: y = 5x - 4

Step-by-step explanation:

A positive slope rises left to right, a negative slope rises right to left.

The slope is [tex]\frac{rise}{run}[/tex].

The y-intercept is where the line meets the y-axis.

The equation is written in the form y = mx + b, where m is the slope and b is the y-intercept.

Hope it helps and is correct!

Hi there!

it is y=80x

As you can see if x=80y then if we say that y=5 then x would be 400. Yiu can also tell that the if the x=5 then the y would be 500 so this wouldn’t make sense.

For B, you can tell that if x is 2 then y would be 160 which is correct if you can see..

Now we know that is B but let find out the others...

If x=y+80 then y always have to change... if x was 2 then the y would be 89 and if the x was 3 than y would be 160.

D is also the same as A but it’s the opposite.. y would be 160 then x would be 2. When y turned into 240 then x would be 3. It changes just like A.

Therefore, the equation that best represent this relationship is y=80x..

Answer:

x = 7y

Answer:

Yes, SSS

Step-by-step explanation:

The triangles have those lines in the sides, and that means that the side is congruent to the corresponding side. Since all three sides are congruent to all three sides on the other triangle, they will be congruent.

Answer: 50.2ft

Step-by-step explanation:

I used tangent to find the length of the base of the triangle.

Tan = opposite / adjacent and I solved for opposite getting 50.2.

PS I literally swore to myself I wouldn’t bring out pen and paper and get into trig tonight over this app but since you asked I did. I’m pretty confident in my answer but just know, I last took math four years ago.

Answer:

−x+−7

Step-by-step explanation:

Let's simplify step-by-step.

4x−6−(5x+1)

Distribute the Negative Sign:

=4x−6+−1(5x+1)

=4x+−6+−1(5x)+(−1)(1)

=4x+−6+−5x+−1

Combine Like Terms:

=4x+−6+−5x+−1

=(4x+−5x)+(−6+−1)

=−x+−7

Answer:

The twelve pack

Step-by-step explanation:

take 16.30 and divide by ten to get the individual price. $1.63

take 17.40 and divide by 12 to get the individual price. $1.45

1.45<1.63

#1

Unit rate:-

#2

Unit rate:-

Hence.

Second one is at better price

Answer:

2/5

Step-by-step explanation:

cause if you put it in a percent it would be 40% so bigger than 35%

Answer:

2/5 is bigger than 35%

Step-by-step explanation:

2/5 can be written as 4/10, which is equivalent to 40/100, or the percentage 40%. And since 40% is bigger than 35%, 2/5 is bigger than 35% :)

Answer:

x = 2, y = -3

or

(2, -3)

Step-by-step explanation:

6x + 2y = 6

7x + 3y = 5

multiply the first equation by -3 and the second equation by 2 and solve by elimination

6x + 2y = 6

becomes

-18 - 6y = -18

7x + 3y = 5

becomes

14x + 6y = 10

then, add the new equations.

-18x - 6y = -18

14x + 6y = 10

-4x + 0 = -8

-4x = -8

4x = 8

x = 2

then, substitute x for 2 in one of the eqautions.

6x + 2y = 6

12 + 2y = 6

2y = 6 - 12

2y = -6

y = -3

Answer:

65%

Step-by-step explanation:

Given data

Cost price= £4000

Selling price=  £1400

% loss= cost price-selling price/cost*100

% loss= 4000-1400/4000*100

% loss= 2600/4000*100

% loss= 0.65*100

% loss= 65%

Hence the %loss is 65%
