Which of these describes the equation –18x + 9y = –416?
A
The equation is not linear because it has 2 variables, not 1.
B
The equation is not linear because it is not in the form y = mx + b.
С
The equation is linear because it has variables with exponents of 0.
D
The equation is linear because it can be rewritten in the form y = mx + b.

Answer:

y=10

Step-by-step explanation:

what ever x='s you add 5 and what ever y='s you subtract 5

Answer:

The answer is 17.5

Step-by-step explanation:

if you divide 17.5 / 5 it will equal the same number as dividing 7 / 2 so 17.5 / 5 = 3.5

Answer:

m∠Y=50°

Step-by-step explanation:

So, we know that ∠S+∠Y=90 and that m∠S=2(m∠Y)-60.

If you plug those things into the equation, you get (2[m∠Y]-60)+m∠Y=90.

Then you multiply 2 and m∠Y: 2m∠Y-60+m∠Y=90.

Combine like terms: 3m∠Y-60=90.

Then you add 60 to both sides: 3m∠Y=150

Divide 3 on both sides: 3∠Y=50

Answer:

Right

Step-by-step explanation:

There is a side that is 90 degress

Answer:

x=2 and y=5

Step-by-step explanation:

Steps:

I will solve your system by substitution.

x=y−3;2x+y=9

Step: Solve x = y − 3 for x:

Step: Substitute y − 3 for x in 2x + y = 9:

2x+y=9

2(y−3)+y=9

3y−6=9(Simplify both sides of the equation)

3y−6+6=9+6(Add 6 to both sides)

3y=15

3y/3=15/3  (Divide both sides by 3)

y=5

Step: Substitute 5 for y in x = y − 3 :

x=y−3

x=5−3

x=2(Simplify both sides of the equation)

Answer:

x=2 and y=5

Answer:

x = 2          y = 5

Step-by-step explanation:

Since we know that

x = y - 3

We can insert that into the equation above:

2(y-3) + y = 9

After having this equation, we can start by multiplying the numbers/variables in the parenthesis by 2.

2y - 6 + y = 9

Then add the common multiples (2y and y)

That makes:

3y - 6 = 9

We need to get 3y on a side by itself, so to do this, we can add 6 to (-6) and (9)

That makes:

3y = 15

Divide the 3 by 3 and 15 to get the y on its own:

y = 5

Now we need to find x, and to do this we can insert y into the equation:

2x + 5 = 9

Now subtract the 5 from the (5) and (9) and you'll get

2x = 4

Then you divide the 2 on both sides and get

x = 2

You can check your work by inserting x and y into the equation

2(2) + 4 = 9  

Sorry for this super long explanation, and hope this helps

Answer:

26, 64

Step-by-step explanation:

we have :

angle 90°

acute angle x

acute angle 2(x+6)

The sum of the angles in a triangle has to be 180° so

90 +x+2(x+6) = 180

90 +x +2x+12 = 180

3x = 180 -90-12

x= 78/3 = 26°

the other acute angle is 2(26+6) = 64°

Answer:

26, 64

Step-by-step explanation:

We can name the first acute angle x and the second acute angle y. We know that x=2(y+6) but we also need another equation to solve the problem. Since we know that the sum of angles in a triangle is equal to 180 degrees and this is a right triangle, the two acute angles sum will be equal to 90 degrees. That would be our second equation, x+y=90. Now we can just substitute the first equation into the second one: 2(y+6)+y=90 -> 2y+12+y=90 ->3y=78 -> y=26

Now we can substitute y into one of the original equations and solve for x: x+26=90 -> x=64

Answer:

She is wrong

Step-by-step explanation:

If our target number is 28 then we can create all of the following factor pairs for this number. These would be the following...

1, 2, 4, 7, 14 and 28

As we can see from the factor pairs there is no 3. This means that 3 would not divide evenly by 28 and cannot be multiplied by any whole number to create 28. Therefore, if you divide the 28 stickers by the 3 friends there will be some stickers leftover always.

Answer:

Terrence would have earned $1575 dollars

Step-by-step explanation:

First we multiply 1.25 by 105.

1.25 * 105 = 131.25

Next we multiply 131.25 by 12.

131.25 * 12 = 1575.

So, the answer is 1575.
