(EASY) WILL MARK BRAINEST! Question: Write an equation in slope intercept form of the line that passes through the given point a

nd is parallel to the graph

Answer:

y = -4x - 38

Step-by-step explanation:

Parallel lines are parallel because they never intersect. As such, they have the same slope. The slope of the line y = -4x + 1 is -4. Substitute m = -4 and the point (-9,-2) into the point slope form of a line.

y -y_1 = m(x-x_1)\\y --2 = -4(x --9)\\y + 2 = -4(x+9)\\

Apply the distributive property to find the slope intercept form.

y + 2 = -4(x+9)

y + 2 = -4x - 36

y = -4x - 38

Answer:

Step-by-step explanation:

The diagram consists of different boxes if the same sizes. Each box is a square with sides measuring 1 cm. The area of each box would be

1 × 1 = 1cm^2

The area of the parallelogram is the total number of squares that it contains. To determine this, the first step is to count the total number of complete squares. Looking at the diagram, there are 11 complete squares. This means

11 × 1 = 11 square units.

The next step is to count the number of incomplete squares and divide by 2. The number of incomplete squares are 8

8/2 = 4

4 × 1 = 4 square units

The area of the parallelogram would be

11 + 4 = 15 square units

Perform the operation indicated, then place the answer in the proper location on the grid. The perimeter of a triangle is 7a - 1
vlada-n [284]

Answer: 4 a - 3 b

Step-by-step explanation:

Since, the perimeter of the triangle = sum of all the three side of the triangle.

Here, two sides of the triangle are 2a + b and a - 9b,

And, the perimeter of the triangle = 7 a - 11

Let third side = x

Therefore, 2 a + b + a - 9 b + x = 7 a - 11 b

⇒ 3 a - 8 b + x = 7 a - 11 b

⇒ x = 7 a - 11 b - 3 a + 8 b

⇒ x = 4 a - 3 b  ( by operating like terms)

If f(x)=x+3 and g(x)= x^2 -4 find the expression for g(f(x))
Maksim231197 [3]

Answer:g(f(x))= x^2 +6x+5

Step-by-step explanation:

g(f(x))= x^2 -4

g(f(x))= (x+3)^2 -4

g(f(x))= (x+3)(x+3) -4

g(f(x))= x^2 +6x+9-4

g(f(x))= x^2 +6x+5

Simplify the expression.
notsponge [240]
The answer is 2k^2 - 7k - 4 because 2k x k is 2k^2 and 2k x (-4) is -8k and 1 x k is k and 1 x (-4) is -4. So then you would get 2k^2 - 8k + k - 4 which simplifies to 2k^2 - 7k - 4 which is your answer.
