How does the graph of g(x)=⌈x⌉+7 differ from the graph of f(x)=⌈x⌉?

1 answer:

8 0

The addition of +7 influences the y values of the graph. Since it is positive, the graph of y=IxI would be moved 7 units upwards.

Hope I helped :)

When Judy worked 4 hours and Ben worked 1 hour, their combined pay was $75. When Judy worked 2 hours and Ben worked 6 hours, the

arsen [322]

Answer:

$15

Step-by-step explanation:

let the hourly rate of pay for Ben = B

let the hourly rate of pay for Judy = J

Judy worked 4 hours and Ben worked 1 hour, their combined pay was $75;

4J + B = 75 ----- i

Judy worked 2 hours and Ben worked 6 hours, their combined pay was $120

2J + 6B = 120 --- ii

Now, we should solve the expression;

Multiply equation ii by 2 and equation i by 1;

4J + B = 75 ----- i x 1 ; 4J + B = 75 -- iii

2J + 6B = 120 --- ii x 2 ; 4J + 12B = 240 ---iv

Now,

equation iv - iii;

11B = 165

B = $15

So, solving for J;

4J + B = 75

4J + 15 = 75

4J = 75 - 15 = 60

J = $15

Is the graph of 6x2 - 2y = 7 a line? Explain.

Hoochie [10]

Answer:

No, it is a parabola. (assuming that you meant to write 6x² - 2y = 7).

Step-by-step explanation:

If there is a square in the x or y, this gives it away that it cannot be a straight line.

First, you would create an equation for this problem.
$\frac{18}{15}$ = $\frac{x}{100}$

Next, you would cross multiply.
15x = 1,800

Now, you would isolate the x. To do this, you would divide both sides by 15.
x = 120

It is a 120% increase.

I hope this helps!

A triangular pyramid has an isosceles triangular base. The base edge of the triangular base is 10

tester [92]

Answer:

h=94.87

Step-by-step explanation:

1. Volume of pyramid formula:

$v=\frac{1}{3}*a^{2}*h$

$a=b*h$ Base Edge * Height of Pyramid

2. We have variables:

V = 480, Base Edge = 10, Height of Base = 16 (Inch)

3. Plug into formula + Rearrange:

$\frac{3V}{h} =(b*h)^{2} [b^{2} *h^{2} ]$

$\frac{3V*b^{2} }{h} =h^{2}$

$h^{2}=\frac{3*480*10^{2} }{16}$

$h=\sqrt{9000}$

h≅94.868
