5 rate?? my brother doesn't want to helpx me someone help?]'

Step-by-step explanation:

2x+y=9 ( y=mx+b)

y=-2x+9

sorry...if its wrong

Answer:

First you have to plot Bart's Garage's fee. Bart's equation is y = 30x + 20, so you would need to plot the points (0, 20) and (1, 50).

Lisa's base fee is the same, so her equation would have a + 20 at the end of it, but her hourly fee is higher. Therefore her hourly fee would be higher than 30. Her equation could be anything above 30, y = 50x +20 would work. The points for that graph are (0, 20) and (1, 70).

Answer:

[tex]( - 2 {x}^{2} + 9x - 2) - ( - 7x + 6) \\ = - 2 {x}^{2} + (9 + 7)x + ( - 2 - 6) \\ = - 2 {x}^{2} + 16x - 8[/tex]

Answer:

24

Step-by-step explanation:

To obtain the minimum number fi tiles needed;

We find the Lowest common multiple of 8 and 6

Multiples of :

6 = 6, 12, 18, 24, 30, 36, 42, 48,...

8 = 8, 16, 24, 32, 40, 48, 56,...

Hence, the lowest common multiple of 8 and 6 is 24

Answer:

6c-5d-3

Step-by-step explanation:

6c-7+d+4-6d=6c-5d-3

Answer:

c is the answer

explination:

4*3 1/2=28/2

28/2 divided by 6 is equal to 7/3 or 2 1/3

Answer:

by phythagoras theorem

(c+b)^2=(8)^2+(6)^2

(b+c)^2=64+36

(b+c)^2=100

b+c=√100

b+c=10.

by phythagoras theorem

(8)^2=(a)^2+(b)^2

64-b^2=a^2. {1}

by phythagoras theorem

(6)^2=(a)^2+(c)^2

36-c^2=a^2. {2}

In equation 1 and 2,

64-b^2=36-c^2

64-36= -c^2+b^2

28= b^2-c^2

28=(b+c)(b-c)

28=10(b-c)

b-c=28/10

b-c=2.8.

b+c=10

b-c=2.8

subtract both equations

c=3.6

option A is correct.

Answer:

is -4=Y

Step-by-step explanation:

i had that problem

Answer:

1: (5,-2) 16

2: (-2,2) √3

3: (-14,21) 2

4: (-7,10) √8

5: (2/3,17) √5

Step-by-step explanation:

Answer:

2

Step-by-step explanation:

OK 13-5=8 and that leaves 8k so k must be 2 because since their is no space they are being multiplied together and 8x2=16 :) hope this helps

plz give thanks

Answer:

(2,-5)

Step-by-step explanation:

Answer:

x = 26

Step-by-step explanation:

1. Information

One can partition this figure into three different parts, two congruent triangles, and one rectangle. To find the value of x, one has to find the base of the two triangles, and then the base of the rectangle. Since opposite sides are congruent, the base of the rectangles is 10. To find the base of the triangle, one has to use the Pythagorean theorem.

2. Base of the rectangle

Again, opposite sides are congruent, hence the base of the rectangle is equivalent to the top part. Hence the base is 10.

3. Base of the triangle

Use the Pythagorean theorem;

[tex]a^{2}+b^{2} = c^{2}\\a-leg\\b-leg\\c-hypotenuse[/tex]

Substitute in the given value and solve

[tex]a^{2}+15^{2} = 17^{2}\\a^{2} + 225 = 289\\a^{2} = 64\\a = 8[/tex]

4. Finding x

There are two congruent trinagles, hence one has to add the base of the triangle twice. The equation will be

x = base_of_triangle + base_of_rectagle + base_of_triangle

x = 8 + 10 + 8

x = 26

Answer:

54 miles per hour.

Step-by-step explanation:

Just divided 621 by 11.5.

You would take 621 and divide that by 11.5 and you would get 54 mph I believe, if I am wrong please let me know so I can take down my answer! have a great and God blessed day! :D

Answer:

40

Step-by-step explanation:

(2x+1/(2x))^5 *(2x -1/(2x))^5

= ((2x)^2 -1/(2x)^2)^5 (a+b)*(a-b) =a2-b2

= (4x^2-1/4(x)^2)^5

now

x =4x^2. ,a = 1/4(x)^2 ,n =5

we have

general term = Cr *x^r *a^(n-r)

= Cr * (4x^2)^r * (1/4(x)^2)^(n-r)

= Cr *4^r * X^2r * 1/( 4^(n-r) *x^(2n-2r)

= Cr * 4^r/4^(n-r) * x^(2r)/x^(2n-2r)

= Cr * 4(2r-n) *x(4r-2n)

now for x^2

4r-2n = 2

4r -10=2

4r =12

r = 3

now for coeff

C(5,3) * 4^(2*3-5)

5!/(3!*(5-3)!) * 4

5*4/(2*1)*4

Answer:

D. One solution

Step-by-step explanation:

Simplify:

[tex]6-3x = 12-6x\\-3x+6x = 12-6\\3x = 6\\x = 2[/tex]

There is only one solution (x=2) that satisfy the equation.

26375

On the graph, it tells you how much fuel is left after 2 hours of the journey.

If we take 422,000 and subtract 369,250 from it we get 52,750. However, this is how much gas is used in 2 hours, so to find one hour we need to divide by 2, getting us 26,375.

Therefore, the Jet uses 26,375 gallons per hour during the 16 hour trip from Los Angeles, CA to Melbourne, Australia.

Answer:

He is at sea level after 34 seconds

Step-by-step explanation:

The height at sea level is given as 0 meters

So the change in height would be;

0- (-17) = 17 meters

There is a gain of 0.5 meters in 1 second

So, the time taken for it to gain 17 meters will be 17/0.5 = 34 seconds

Answer:

i dont know which one to choose but chicken tenders

Answer:

Chicken tenders.

Step-by-step explanation:

Chicken nuggets are the gross consumption of organs including lungs and others mushed together and fried. In return kids run to it because (most) kids only eat gross stuff. This made the marketing campaign SKY ROCKET with kids everywhere trying to get a bite. FORCING their poor parents to get them that disgusting mush. And then dip it in ketchup. Which is NOT a fruit or veggie. (As the school system thinks they are a veggie.)

While chicken tenders are chopped off the chicken meat then rolled in bread crumbs. And then deep fried to make a crispy exterior with a delicious tender interior.  Without getting mushed together with other things.

Also you never know what they put in that chicken nugget since its mushed together ‍♀️.
