Answer:

y=-2x

Step-by-step explanation:

The function has the table:

x f(x)

-3 -6

-2 -4

-1 -2

0 0

Looking at the table, f(x) deceases by 2 each time. This is a constant rate of change called slope. This is a linear function and its equation can be written using y = mx+b. m = -2. b is the y-intercept for starting point where x = 0. When x=0, the table shows y=0. So b=0.

This means the rule is y = -2x.

Does anybody have any tips for calculating slopes in Algebra 1???

I am Lyosha [343]

Answer:

The equations are really hard, so if you can find a slope interpreter or something that might be helpful.

I find it easier to just count the up and across.

Human blood has an approximate pH of 7.3. Which substance is more basic than human blood?

ratelena [41]

so, 7 is neutral anything past 7 is considered basic.

answer: <em>a water and ammonia solution with a pH of 11 (very basic).</em>

<em />any number under 7 is acidic and of course there are different degrees of acidic just like there are different degrees of basicity.

______________________________________________________________

- stomach's digestive juices, would be considered very acidic

-apple juice is also acidic but not as acidic like stomach juices.

- grape juice, is becoming less acidic.

Hopefully this helped and good luck.

Find x. A. 11√6/2 B. 22 C. 33 D. 11√3/2

Phoenix [80]

Answer:

B

Step-by-step explanation:

using the tangent ratio on the triangle on the right and the exact value

tan60° = $\sqrt{3}$ , then letting the altitude be h

tan60° = $\frac{opposite}{adjacent}$ = $\frac{11\sqrt{6} }{h}$ = $\sqrt{3}$ ( multiply both sides by h )

11 $\sqrt{6}$ = h × $\sqrt{3}$ ( divide both sides by $\sqrt{3}$ )

11 $\sqrt{2}$ = h

using the sine ratio in the triangle on the left and the exact value

sin45° = $\frac{\sqrt{2} }{2}$ , then

sin45° = $\frac{opposite}{hypotenuse}$ = $\frac{h}{x}$ = $\frac{11\sqrt{2} }{x}$ = $\frac{\sqrt{2} }{2}$ ( cross- multiply )

$\sqrt{2}$ × x = 22 $\sqrt{2}$ ( divide both sides by $\sqrt{2}$ )

x = 22
