HELPPP pleaseeeeeeeee

Answer:

x = 20, y = 110

Step-by-step explanation:

For x:

[tex]5x + 45 + 3x - 25 = 180\\8x + 20 = 180\\8x = 160\\x = 20[/tex]

For y:

[tex]y + 2x - 5 + 3x - 25 = 180\\y + 2(20) - 5 + 3(20) - 25 = 180\\y + 40 - 5 + 60 - 25 = 180\\y + 35 + 35 = 180\\y + 70 = 180\\y = 110[/tex]

make the denominators the same so you cancompare

Answer:

Option (A)

Step-by-step explanation:

Let the equation of the linear function representing number of party guests (c) and total cost (p) is in the form of c = mp + b

m = Slope of the line

b = y-intercept

Choose the two ordered pairs from the table (3, 274) and (7, 306).

Slope of the function 'm' = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

m = [tex]\frac{306-274}{7-3}[/tex]

m = 8

Since, equation of a line passing through (x', y') and slope m is,

y - y' = m(x - x')

Therefore, equation of a line passing through (3, 274) and slope = 8,

y - 274 = 8(x - 3)

y - 274 = 8x - 24

y = 8x + 274 - 24

y = 8x + 250

Since, y = p and x = c

Therefore, p = 8c + 250 will be the equation.

Option (A) is the answer.

Answer:

The correct answer is 1 feet/2.54 cm because the cm would cancel out

Step-by-step explanation:

Here, we want the ratio that would allow us convert from 45 cm into feet.

The correct answer here is 1 feet/2.54 cm because the cm would cancel out, leaving us with the feet only.

It would be a case like;

1 feet/2.54 cm * 45 cm

So, we would have;

(45 cm * 1 feet)/2.54 cm

Answer:

Positive

Step-by-step explanation:

Positive

Step-by-step explanation:

-7 + 28 = 21

Answer:

The closest answer is 12.

Step-by-step explanation:

Since 12 multiplied by 35 is 420, it is the closest answer. 16.5 seconds is too much. 335 seconds is WAY too much to reach 407 meters. 8.15 seconds is too little. It is at least half of how much you want it to move.

Go to cordinate plane and then find distance.

Answer:

A.  RS, ST, RT, TS , SR TR

Step-by-step explanation:

Answer:

see below

Step-by-step explanation:

Assuming that

Point A is the same as point X

Point B is Point Y

Point C is Point Z

So we have

[tex]X=(1,5)\\\\Y=(2,2)\\\\Z=(6,1)[/tex]

the rule for a rotation of 180° is

For 180 degrees, the rule is (a, b) --------> (-a, -b)

so we have

[tex]X'=(-1,-5)\\\\Y'=(-2,-2)\\\\Z'=(6,1)[/tex]

the rule for reflection across the x axis

(a,b)----->(a,-b)

so we have

[tex]X''=(1,-5)\\\\Y''=(2,-2)\\\\Z''=(6,-1)[/tex]

Answer:

The slope of the line is 0 (there is no change in the y-axis)

Step-by-step explanation:

Here, we want to find the slope of the line that passes through the given points

We use a formula for this;

Mathematically;

m = y2-y1/x2-x1

Substituting the values;

m= (3.5-7/2)/3.5+4.5 = 0/8 = 0

The slope of the line is 0

Answer: The Earth makes one rotation every day.

Step-by-step explanation:

==========================================================

The given points are T(3,1) and U(5,3)

The x coordinates of these given points are 3 and 5. Add them up to get 3+5 = 8. Then cut this in half getting 8/2 = 4. This is the x coordinate of the midpoint.

The y coordinates are 1 and 3. They add to 1+3 = 4. Then that cuts in half to get 4/2 = 2. This is the y coordinate of the midpoint.

The midpoint is (4,2)

Effectively, we just used the midpoint formula

[tex](x_m, y_m) = \left( \frac{x_1+x_2}{2}, \frac{y_1+y_2}{2} \right)[/tex]

In short: add the corresponding coordinates, then divide by 2.

Answer:

g=34/11 0r g = 3.09 (approx)

Step-by-step explanation:

1/2g + 32 = 6g + 15

=> 32-15 = 6g-1/2g

=> 17 = 11/2g

=> 34/11 = g

or

g = 3.09 (approx.)

Answer:

a)value attached below

b)Yo = [tex]\frac{-27}{20}[/tex]

Step-by-step explanation:

A) solving initial value problem  

[tex]y' - 5y = 15t + 3e^t[/tex]

y(0) = yo

hence the solution of the initial value problem : y(t)

Y(t) =

Attached below is the detailed solution

B) Yo = [tex]\frac{-27}{20}[/tex]  separates the solutions  as

t →∞

this is because when  y(t) < [tex]\frac{-27}{20} y(t) tends to inifiniy[/tex]

                                     y(t) > [tex]\frac{-27}{20} y(t) tends to inifinity[/tex]
