This ones kinda hard I'm not really sure, but looking at the table, when f(x) = 1, g(x) = 1. So therefore it is yes, and Im guessing you know the negative and positive x coordinates/zero thing, so I think you should be correct. Sorry if this is wrong, not too sure, but hopefully it gives you a better idea.

Answer:

Yes, at negative and positive x-coordinates or zero

Step-by-step explanation:

we have

$x^{2} +y^{2}=9$

Equation of the circle with center at the origin and radius equal to $3$ units

g(x) -------> a linear function (see the table)

using a graphing tool

Plot the graph of the circle and the three points of the linear function g(x)

Both graphs intersect at negative and positive x-coordinates

see the attached figure

Julio and David were in Target and decided to check out the clearance section. They found pencils and erasers that were on sale

Sati [7]

Answer:

Cost of one pencil: $\$0.07$

Cost of one eraser: $\$0.03$

Step-by-step explanation:

Let be "p" the cost in dollars of one pencil and "e" the cost in dollars of one eraser.

Based on the information given in the exercise, you can set up the following system of equations:

$\left \{ {{4p+3e=0.37} \atop {3p+4e=0.33 }} \right.$

You can use the Elimination Method to solve the system of equations.

Multiply the first equation by -3 ad the second one by 4. Then add the equations and solve for "e":

{ $\left \{ {{-12p-9e=-1.11} \atop {12p+16e=1.32}} \right.\\..........................\\7e=0.21\\\\e=0.03$

Substitute the value of "e" into any original equation and solve for "p":

$4p+3(0.03)=0.37\\\\p=\frac{0.28}{4}\\\\p=0.07$

The volume of a rectangular box is 330 cubic inches. The length on one side of the top is 11 inches, and the height of the box i

Fiesta28 [93]

Answer: 110 square inches.

Step-by-step explanation:

The volume of a rectangular box would be:

$V=length*width*height$

In this case, we know the volume, the length and the height, and we don't know the width, so we're going to isolate it:

$width=\frac{V}{length*height}$

Substituting the data:

$width=\frac{330}{11*3} =10in$

This width is also the width of the top of the box, so the area of the top would be:

$A=length*width\\A=11*10\\A=110in^{2}$

<span>Evan rounded 4.8 down to 4. His estimate of 32 is too low.

Answer:

48 questions.

Step-by-step explanation:

x is for the unknown variable, the number you are trying to figure out.

12= 25%x

if you convert to a fraction, 12 is 1/4 of x. if you then multiply your answer by 4, 12 is 25% of 48.

to figure this out you can also ask, 12 is 25% of what number?
