Answer:

222 cm²

Step-by-step explanation:

For the rectangle's area you do 15×12= 180

And the the triangle is 12×7÷2= 42 (you divide by 2 because the triangle is half of a rectangle)

So then you just add them together and you get 222 cm²

$\qquad\qquad\huge\underline{{\sf Answer}}♨$

Let's write the equation of line in slope point form ~

$\qquad \sf \dashrightarrow \:y - y1 = m(x - x1)$

$\qquad \sf \dashrightarrow \:y -2 = 3(x -1)$

$\qquad \sf \dashrightarrow \:y -2 = 3x - 3$

$\qquad \sf \dashrightarrow \:y = 3x -1$

Now, let's use this equation of line to plot two points ~

when x = 0, y = (3 × 0) - 1 = - 1

when x = -1, y = (3 × -1) -1 = -4

Now, plot these points on graph ~

(0 , -1) and (-1, -4)

What is the 15th term of the sequence A(n) = 50 - 3(n-1) ?

Alexus [3.1K]

Answer:

$A(15)=8$

Step-by-step explanation:

Given that,

$A(n)=50 - 3(n-1)$

We need to find the 15th term of the sequence. Put n = 15 in the above sequence so that,

$A(15)=50 - 3(15-1)\\\\A(15)=50-3(14)\\\\A(15)=50-42\\\\A(15)=8$

So, the 15th term of the sequence is 8.

Solve the system of equations using subtraction. Equation 1: 3x-2y= -2 Equation 2: 3x + y = 10 The solution is (? ,?) HURRY PLEA

Art [367]

Answer:

the solution is x = 2 and y = 4 OR (2,4)

Step-by-step explanation:

From the question

Equation 1: 3x-2y= -2

Equation 2: 3x + y = 10

Subtract equation 1 from equation 2, that is

3x + y = 10 - (3x -2y = -2)

You get

3x - 3x + y - (-2y) = 10 - (-2)

0 + y + 2y = 10 + 2

3y = 12

Divide both sides by 3

∴ y = 12/3

y = 4

Substitute the value of y into equation 2 to get x

3x + y = 10

3x + 4 = 10

Then,

3x = 10 - 4

3x = 6

Divide both sides by 3

∴ x = 6/3

x = 2

Hence, the solution is x = 2 and y = 4
