Given:

\text{ Dimension = 3}\times5

Sol:

Area of picture is:

\begin{gathered} =\text{ length}\times\text{ Width} \\  \\ =15 \end{gathered}

If the cost $10 per square inch then price of 15 square inch is:

\begin{gathered} =15\times10 \\  \\ =150 \end{gathered}

If the quadruple of dimension that mean:

\begin{gathered} \text{ l ength = 4 length} \\  \\ Width\text{ = 4 width} \end{gathered}

So area is:

\begin{gathered} A=4\text{ length}\times4\text{ Width} \\  \\ A=4(15) \\  \\ A=60 \end{gathered}

So price is:

\begin{gathered} =60\times10 \\  \\ =600 \end{gathered}

Please help me out with these no one is helping me.<br>Please anyone <br>​
Olin [163]

Answer:

Below.

Step-by-step explanation:

You find the values of y by substituting the values of x in the expression x^2 + 3x - 1.

So f(-4) = (-4)^2 + 3(-4) - 1 = 16-12-1 = 3

in the same way  f(-3) = -1, f(-2) = -3, f(-1) = -3,

f(0) = -1 and f(1) = 3.

Now plot the points (-4, 3) , (-3, -1) and so on  

Then you can read the values off this graph.

Answer:

Ivy is 6 years old and Rose is 12 years old.

Step-by-step explanation:

To solve this problem, two variables are necessary since we have two unknown variables: Ivy's age and Rose's age.

Ivy's age will be x

and Rose's age will be y

"Ivy is half as old as her sister":

x=\frac{y}{2}

this will be our <u>fist equation.</u>

"In six years, Ivy will be two-thirds as old as Rose"

in six years Ivy will have x+6 years, and Rose will have y +6 years, so for this sentence we have the equation:

x+6=\frac{2}{3}(y+6)

this will be our <u>second equation.</u>

Substituting the value of x from the first equation into the second, and solving for y(Rose):

\frac{y}{2}+6=\frac{2}{3} (y+6)\\\frac{y+12}{2} =\frac{2}{3} (y+6)\\y+12=\frac{4}{3} (y+6)\\3(y+12)=4(y+6)\\3y+36=4y+24\\36-24=4y-3y\\12=y

Rose is 12 years old.

and Ivy (using the fist equation):

x=\frac{12}{2}=6

Ivy is 6 years old.

What is the slope of a line that contains the two points (0, 3) and (4, 5)?
Anika [276]

The formula for slope is (y2 -- y1) / (x2 -- x1).

(0,3) (4,5)

5 - 4 = 1

3 - 0 = 3

So the slope is 1/3.

Hope this Helps!!
