Write the equation of the line that is parallel to the graph of y=-4x-9 and whose y intercept is 3

1 answer:

8 0

Y = -4x - 9
The new line has the same slope as the one above, that is - 4
A y intercept means the point (in this case) is 0,3 [The x value is 3]

y = -4x + b Now use (0,3)
3 = 0 + b
b = 3

y = - 4x + 3 is the line you want.

Karl is putting a frame around a rectangular photograph. The photograph is 14 inches long and 10 inches wide, and the frame is t

Sergeu [11.5K]

<h2>The area of the framed photograph = 1156 $inch^{2}$ </h2>

Step-by-step explanation:

Given,

The length of photograph (l) = 14 inches and

The breadth of photograph (b) = 10 inches

To find, the area of the framed photograph = ?

We know that,

The area of the framed photograph = (l + 2b)(l + 2b)

= (14 + 2 × 10) (14 + 2 × 10) $inch^{2}$

= (14 + 20) (14 + 20) $inch^{2}$

= (34) (34) $inch^{2}$

= 1156 $inch^{2}$

∴ The area of the framed photograph = 1156 $inch^{2}$

alex41 [277]

Steps to solve:

47.5 + 4.5x ≤ 65

~Subtract 47.5 to both sides

4.5x ≤ 17.5

~Divide 4.5 to both sides

x ≤ 3.8888888889...

So, yes, the friends will have to share snacks.

Best of Luck!

The number of books borrowed from a library each week follows a normal distribution. When a sample is taken for several weeks, t

Marat540 [252]

$\mathbb P(X>250)=\mathbb P\left(\dfrac{X-190}{30}>\dfrac{250-190}{30}\right)=\mathbb P(Z>2)\approx0.0228$

Or, if you're familiar with the empirical rule and the basic properties of the normal distribution, you can use the fact that approximately $95/%$ of the distribution lies within two standard deviations of the mean, or

$\mathbb P(|Z|$

which means about $5\%$ of the distribution lies outside this interval, or

$\mathbb P((-22))\approx0.05$

Because the distribution is symmetric, you have

$\mathbb P(-22)$
$\implies \mathbb P((-22))=\mathbb P(-22)=2\mathbb P(Z>2)\approx0.05$
$\implies \mathbb P(Z>2)\approx 0.025$
