Answer:

y = 2x + 10

Step-by-step explanation:

y1 = 4

x1 = -3

slope,m = 2

y - y1 = m(x - x1)

y - 4 = 2(x + 3)

y - 4 = 2x + 6

y = 2x + 10

A number line is drawn left to right with integers spaced 1 centimeter apart. An ant crawls onto the number line at +3. It then

Anna11 [10]

Answer:

-1.2 cm

Step-by-step explanation:

Let's figure out where the ant is after each step.

Step 1

Start at +3.0

Move left - 1.5

Now at +1.5

Step 2

Start at +1.5

Move right + 4.9

Now at +6.4

Step 3

Start at +6.4

Move left - 7.6

Now at -1.2

The ant is now at -1.2 cm.

A circle with the diameter of 20 mm is showing what is the exact Sir conference obvious and then question to what is the approxi

yaroslaw [1]

Answer:

The approximate circumference is 62.8 mm

Step-by-step explanation:

Circumference is basically the perimeter of the circle

Circumference is given by

$2 *\pi *r$

Here the diameter is 20 mm, so the radius will be half of diameter = 10 mm

Substituting the given values, in above equation, we get -

Circumference =

$2 *3.14 * 10 \\62.8$ mm

The approximate circumference is 62.8 mm

Small squares with sides 4 cm were cut from each of the corners of a square piece of cardboard. then it was folded into an open-

DENIUS [597]

Suppose the length of the card board was x cm by x cm
After squares of 4cm was cut from the corner, the dimension for the box will be:
length=(x-8) cm
width=(x-8) cm
height=4 cm
thus the volume will be:
V=length*width*height
V=4×(x-8)×(x-8)=144
x²-16x+64=36
this can be simplified to form a quadratic equation given by:
x²-16x+28=0
solving the quadratic equation we get:
x=2 or x=14
Thus we conclude that the original dimensions was:
length=14 cm ; width=14 cm

What can you say about the quotient, when you divide 23 by something equal to 1?

Gwar [14]

Answer: the quotient will be equal to 23

The equation to calculate what divided by 23 equals 1 is as follows:

X/23 = 1

Where X is the answer. When we solve the equation by multiplying each side by 23, you get get:

X = 23

Therefore, the answer to what divided by 23 equals 1 is 23

so the quotient will be equal to 23
