Answer:

a. y = 3 × 0 + 15

y= 0+15

y= 15

Step-by-step explanation:

Subtitute the variables into the place they are denoted with and solve it

And the place where the equation will cross the y axis is just the last numbers i.e. 15 and 3z which is 6

Answer:

equation: a/.5b=h

h=9

Step-by-step explanation:

a=1/2bh

divide both sides by 1/2b to get h alone

a/.5b=h

a/.5b=h

54/0.5(12)=h

54/6=h

9=h

If √6 is the geometric mean between 4 and another number, then the number is<br> 1.5<br> 9<br> 24
konstantin123 [22]
Correct answer is A.

g - geometric mean
g= \sqrt{ab} &#10;\\&#10;\\g= \sqrt{6} ,a=4,b=?&#10;\\ \sqrt{6}= \sqrt{4b} &#10;\\  (\sqrt{6})^2= (\sqrt{4b} )^2&#10;\\6=4b&#10;\\&#10;\\b= \frac{6}{4} = \frac{3}{2}=1.5

Suppose z is proportional to the square root of x. If z = 717 when x = 9, find the proportionality constant k.??
Dahasolnce [82]

Answer:

  239

Step-by-step explanation:

Write the equation. Fill in the given values, and solve for the unknown,

  z = k√x

  717 = k√9

  k = 717/3 = 239

The constant of proportionality is 239.

Answer:

D

Step-by-step explanation:

Remember how absolute values turn everything inside of it into a positive number? Like |-4|=4 and |4|=4 as well.

Well, it works the same for equations.

When you have an absolute value equation like this, you have to split it into two parts.

The positive version

| d-3.5 | ≤ 1.5

and the negative version

|-(d-3.5)| ≤ 1.5

solve for the value of d in both equation.

<em>Remember that you have to flip the inequality sign when dividing or multiplying by a negative number</em>

I assume you know how to graph the inequality once you get the value for d.

d≤5 and d≥2

so

2 ≤ d ≤ 5

meaning d is between 2 and 5.
