3x+y=9 and 3x=9-y solve each system by elimination to prove your answer, I am stuck on this one

Answers

Answer 1

Answer: Infinitely many solutions.I will try to solve your system of equations.3x+y=9;3x=−y+9Step: Solve3x+y=9for y:3x+y+−3x=9+−3x(Add -3x to both sides)y=−3x+9Step: Substitute−3x+9foryin3x=−y+9:3x=−y+93x=−(−3x+9)+93x=3x(Simplify both sides of the equation)3x+−3x=3x+−3x(Add -3x to both sides)

so ur answer is
Infinitely many solutions.

Find the values of x and y.

Answers

Refer to the notations above:

<BCD+40°=180° (angles on a strainght line)
<BCD=180°-40°
<BCD=140°

As BC=CD(given),△BCD is an isosceles triangle,thus <CBD=<CDB=x(properties of isosceles triangle).

We can then proceed to find x(<CDB and <CBD):

140°+ x + x=180°(angles sum of triangles)
2x=180°-140°
x=40°/2
x=20°

Then, we can again use the angles sum of triangle to solve y:

y+90°+20°=180°
y=180°-90°-20°
y=70°

Therefore, x=20° and y=70°.

Carl puts $1.10 in his penny bank every day in the month of July (31 days) his total saving was 55.00 at the end of June. What’s the best estimate for Carl’s savings at the end of July

Answers

He saves $1.10 everyday in July.

So he will have ($1.10 x 31) = $34.10 saved in July.

His total savings will be ($34.10 + 55)

Hence he will have a total of $89.10 at the end of July.

ANSWER:
He will have $89.10 at the end of July.

You will need to find how much he got on July so you will need to multiply 1.10 and 31.

1.10 time 31 is 34.1

Then subtract 55-34.1=20.9

Answer:20.9

What is the slope of the line on the graph?

Enter your answer in the box.

Answers

To find the slope,we can use the slope formula:
$(y1 - y2)/(x1 - x2)$
Where x and y are y coordinates and x coordinates respectively.

To find the answer, put any two points into the formula.

In this case, (1,5) and (0,-1) will be used:

x1 and y1 would be the x and y coordinate in the first point(1,5), while x2 and y2 would be the x and y coordinate in the first point (0,-1)

$(5 - ( - 1))/( 1- 0) \n = (5 + 1)/(1) \n = ( 6)/(1) \n = 6$
Therefore the answer is 6.

Hope it helps!
