Find the x-intercept and y-intercept

Mathematics
1 answer:
Aneli [31]3 years ago
8 0

Answer:

x - intercept:  (-22, 0)

y - intercept: (0, 11)

Step-by-step explanation:

Given the linear equation

-3x + 11y = 66

<em><u>Determining the x-intercept</u></em>

We know that the x-intercept can be computed by setting the value y=0 and solving for x.

substitute y = 0

-3x + 11y = 66

-3x + 11(0) = 66

-3x + 0 = 66

-3x = 66

Divide both sides by -3

-3x/-3 = 66/-3

x = -22

Thus, the ordered pair representing the x-intercept : (-22, 0)

<em><u>Determining the y-intercept</u></em>

We know that the y-intercept can be computed by setting the value x=0 and solving for y.

substitute x = 0

-3x + 11y = 66

-3(0) + 11y = 66

0 + 11y = 66

11y = 66

Divide both sides by 11

11y/11 = 66/6

y = 11

Thus, the ordered pair representing the y-intercept : (0, 11)

Therefore, we conclude that:

x - intercept:  (-22, 0)

y - intercept: (0, 11)

Answer:

The difference is that the rate is just one thing and the the set of data values are more than one value.They are in a set.

Sorry there is no explanation to this this is not literally math.

An art classroom has 5 boxes with sharpie pens and clipboards. Each box has 4 sharpies there are 25 supplies in all how many tot
Step2247 [10]

Answer:

1 clipboard per box

Step-by-step explanation:

First, multiply 4 by 5 (because we need to see how many supplies there are already taken up)

4x5= 20

Next, subtract 25 from 20 (to see how many total clipboards there are)

25-20= 5

Since there are 5 boxes, we divide the number of clipboards(5) by the number boxes(5):

5/5= 1

Consider the following quadratic equation: 25x2=36 Using the standard form ax2+bx+c=0 of the given quadratic equation, factor th
Stells [14]

Answer:

  (5x -6)(5x +6) = 0

Step-by-step explanation:

Subtract 36 to put the equation in standard form. In this form, it looks like the difference of squares, so can be factored as such.

  25x^2 -36 = 0

  (5x)^2 -6^2 = 0

  (5x -6)(5x +6) = 0

(X+2)^2+(y-4)^2=16 what is the radius
Sholpan [36]

Answer:

The radius = 4

Step-by-step explanation:

considering the equation

\left(x+2\right)^2+\left(y-4\right)^2=16

As the standard form of the circle is

\left(x-h\right)^2+\left(y-k\right)^2=r^2

Match the values in this circle to those of the standard form.

  • The variable  r represents the radius of the circle,  
  • h represents the x-offset from the origin, and  
  • k  represents the y-offset from origin.

\mathrm{Rewrite}\:\left(x+2\right)^2+\left(y-4\right)^2=16\:\mathrm{in\:the\:form\:of\:the\:standard\:circle\:equation}

\left(x-\left(-2\right)\right)^2+\left(y-4\right)^2=4^2

\mathrm{Therefore\:the\:circle\:properties\:are:}

\left(h,\:k\right)=\left(-2,\:4\right),\:r=4

Therefore, the radius = 4
