(-2,2) and (0, -2)

Slope = (2 + 2) / (-2 - 0) = 4/-2 = -2

Slope m = -2 and y-intercept b = -2

so equation for linear function: y = -2x - 2

The inequality on the graph is the solid line (=) and the shaded below the line (<) so the equation is:

y <= -2x - 2

Answer is B) y <= -2x - 2

It would be $y\leq -2x-2$ because the y-intercept is -2 and the slope is $\frac{-2}{1}$ . Also, 0,0 does not fit in to the greater than equation.

Step-by-step explanation:

if we do unitary method

then..

Anna buys 12 pens and 20 pencils for a total cost of $16. One pen costs $0.40 more than a pencil. What would one pencil and one

Mamont248 [21]

$12x+20y=16$ where x is a pen and y is a pencil. Because a pen is .40 more than a pencil we can write this in terms of pencils and extra .40:

$32y+12*.4 = 16\\=32y+4.8 = 16\\=32y+4.8-4.8 = 16-4.8\\=32y = 11.2\\=32y/32 = 11.2/32\\=y = 0.35$

Therefore, a pencil costs 0.35 and a pen costs 0.75. Combined, one of each costs 1.10 dollars.

Consider a regular pyramid A with a square base and a right circular cone B.

Angelina_Jolie [31]

Answer:

Pyramid

Step-by-step explanation:

$\text{Volume of a Square Pyramid }=\frac{1}{3} \times l^2 \times Height\\\\ \text{Volume of a Cone }=\frac{1}{3} \pi r^2 \times Height$

Given that the two solids have the same volume

$\frac{1}{3} \times l^2 \times Height=\frac{1}{3} \pi r^2 \times Height$

If the length of a side of the square base of pyramid A is the same as the base radius of cone B. i.e l=r

$\frac{1}{3} \times l^2 \times $Height of Pyramid=$\frac{1}{3} \pi l^2 \times $Height of cone$\\\\$Cancel out $ \frac{1}{3} \times l^2$ on both sides\\\\Height of Pyramid= \pi \times $ Height of cone$$

If the height of the cone is 1

$H$eight of Pyramid= \pi \times 1 \approx 3.14$ units$

Therefore, the pyramid has a greater height.
