Answer:

6

Step-by-step explanation:

The slope is: \frac{y_{2} -y_{1} }{x_{2} -x_{1} }. In this case, for the numerator you get 30. For the denominator you get 5. Divide 30/5 to get 6 as your final slope.

Hope it helps!

Whats the area of this shape
forsale [732]
First cut the shape into a square, triangle and rectangle. Then add all 3 areas. Area of a quadrilateral is A= b x h So once square is 4 X 4= 16. The rectangle has a area of 4 x 2= 8. The triangle, using the formula 1/2bh has an area of 1/2 x 2 x 4 = 4. So the area of the shape is 16 + 8 + 4 = 28 units

Solve the inequality 3x^2 + 10x - 8 < 0​
Ksivusya [100]

Step-by-step explanation:

Given, 3x−2<2x+1

⇒3x−2x<1+2

⇒x<3orx∈(−∞,3)

The lines y=3x−2 and y=2x+1 both will intersect at x=3

Clearly, the dark line shows the solution of 3x−2<2x+1.

Toucans and​ blue-and-yellow macaws are both tropical birds. The length of the toucan in the picture to the right is about two t
Sergeu [11.5K]

Answer:

The length of the​ blue-and-yellow macaw is 42 in

Step-by-step explanation:

Let

x ----> the length of the toucan in inches

y ----> the length of the​ blue-and-yellow macaw in inches

we know that

x=\frac{2}{3}y ----> equation A

x=28 ----> equation B

substitute equation B in equation A and solve for y

28=\frac{2}{3}y

Multiply by 3 both sides to remove the fraction

28(3)=2y

Divide by 2 both sides

y=\frac{28(3)}{2}=42\ in

therefore

The length of the​ blue-and-yellow macaw is 42 in
