Answer:

1st do you do 6 × 3 to get 18 and then you add that by 4 because parentheses come 1st. You want to use Pemdas so you do 1/2 times 22 and then you want to subtract 9 from 22 to get 12.

At the beach this weekend, the ratio of sandcastles to kites was 3 to 5. If there were 15 kites spotted, how many items were see
Gelneren [198K]

Answer: 24

Step-by-step explanation:

The ratio of sandcastles to kites was 3 to 5 so if 15 kites were spotted that meant that the 5 was multiplied by 3 so then we multiply the 3 by 3. Now there are 9 sandcastles and 15 kites so now we add 9 to 15 to figure out how many items were seen in all. Nine added to 15 equals 24 which means that 24 items were seen in total.

Use the same coordinate plane to draw the graphs of the functions. Y=kx-2 if k=1, 0.4,-1
mario62 [17]

Graphs can be used to represent functions.

See attachment for the graphs of: <em>y =x - 2, y = 0.4x - 2, y =-x - 2</em>

The function is given as: \mathbf{y = kx - 2}

When k = 1,

We have:

\mathbf{y = 1\times x - 2} ----- substitution property of equations

\mathbf{y = x - 2}

So, the equation is: \mathbf{y = x - 2} when k = 1

When k = 0.4,

We have:

\mathbf{y = 0.4\times x - 2} ----- substitution property of equations

\mathbf{y = 0.4x - 2}

So, the equation is: \mathbf{y = 0.4x - 2} when k = 0.4

When k = -1,

We have:

\mathbf{y = -1\times x - 2} ----- substitution property of equations

\mathbf{y = -x - 2}

So, the equation is: \mathbf{y = -x - 2} when k = -1

See attachment for the graphs of: \mathbf{y = x - 2}, \mathbf{y = 0.4x - 2} and \mathbf{y = -x - 2}
