Answer:

-1,0,1,2,3

y=2x

y=-2

y=0

y=2

y=4

y=6

y=4x

y=-4

y=0

y=4

y=8

y=12

y=8x

y=-8

y=0

y=8

y=16

y=24

The lines change. when it is y=2x, then everytime it goes up by 2. when y=4x, goes up by 4 and so on. To graph them, do not graph any lines that show y=2x with an x in it. To graph y, go on the x axis y=0 = the whole line on the x axis. y=-2 = 0-2 or 0,-2 and 1,-2 so to graph a line, put the number 0 into the y, like 0,24 then mark that spot, the add 1, and mark that spot and so on.

Hope this helps plz hit the crown ;D and graph all those lines above!

Matter is in a liquid state when its temperature is between its melting point and its boiling point. Suppose that some substance

alexgriva [62]

Answer:

96.512 °F < x < 591.242 °F

Step-by-step explanation:

We are given;

Melting point = 35.84 °C

Boiling point = 310.69 °C

Now, we are given that formula to convert °C to °F is;

°C = (5/9)°F

Thus if the temperature in Fahrenheit is x, then;

Melting point is; 35.84 °C = (5/9)x°F - "32"

x = ((9 × 35.84)/5) + 32

x = 96.512 °F

Similarly, for Boiling point;

Boiling point is;

310.69 °C = (5/9)x°F - "32"

x = ((9 × 310.69)/5) + 32

x = 591.242 °F

Now, we are told that matter is in its liquid form when it is between melting and boiling point.

Thus, range of x in inequality form is;

96.512 °F < x < 591.242 °F

Equation of the existing water pipe's line

a) slope, m = rise / run = Δy / Δx = 3/2

b) y-intercept, b = 3

equation: y = mx + b = (3/2)x + 3

Equation of the new water pipe's line

slope, m = - 1 / (slope of the perpendicular line) = - 1 / (3/2) = - 2/3

point (0,2)

=> y - 2 = (-2/3) (x - 0) => y = (-2/3)x + 2 <---- equation of the new pipe

28)

two parallel lines have the same slope =>

slope, m = rise / run = Δy / Δx = [4 - 0] / [11 - 8] = 4 / 3

point (4,5) => y - 5 = (4/3) (x - 4)

=> y = (4/3)x - 16/3 + 5 = (4/3)x - 1/3

y = (4/3)x - 1/3 <--- equation of the new bike path

A bicycle tire is 28 inches in diameter.

Andrej [43]

Answer:

Option A.) 88 inches

Step-by-step explanation:

step 1

Find the circumference of the wheel

we know that

The circumference of a circle is equal to

$C=\pi D$

we have

$D=28\ in$

$\pi =\frac{22}{7}$

substitute

$C=(\frac{22}{7})(28)=88\ in$

Equation B is written in vertex form, which means you can read the vertex (extreme value) from the numbers in the equation.

Vertex form is
y = a(x -h)² + k
where the vertex (extreme point) is (h, k). Whether that is a maximum or a minimum depends on the sign of "a". When "a" is negative, the graph is a parabola that opens downward, so the vertex is a maximum.

Equation B reveals its extreme value without needing to be altered.
The extreme value of this equation is a maximum at the point (2, 5).
