Find the equation of the line parallel to y = -3x + 4 with a y-intercept of -10

The correct answer is y=-3x-10

when a line is parallel to another line that means the slip of the lines are going to be the same and since the y-intercept of the other line was given to you, you would just put them together in one equation.

Answer:

y=-3x-10

Step-by-step explanation:

Hi there!

We need to find the equation of the line parallel to y=-3x+4 that has the y intercept of -10 (the point (0, -10))

Parallel lines have the same slope

The slope of y=-3x+4 is -3 (it is in the placement of where m (slope) is in y=mx+b)

So the slope of the new line parallel to y=-3x+4 is also -3

Here is the equation of that line so far:

y=-3x+b

b is a placeholder for the y intercept

However, we are given the y intercept as -10, so substitute -10 as b into the equation

y=-3x-10

There's the equation of the line parallel to y=-3x+4 with a y intercept of -10

Hope this helps!

Answer:

$\boxed{\sf \frac{15}{22} }$

Step-by-step explanation:

The radius of the circle is 7 cm.

The two legs of the triangles are 7cm as well.

Area of a trinagle is ( base × height )/2.

$\frac{7 \times 7}{2} =24.5$

Multiply the value by 2 since there are two triangles.

$24.5 \times 2 = 49$

Calculate the area of the circle.

$\pi r^2$

The radius is given.

$\pi (7)^2$

Take $\pi$ as $\frac{22}{7}$

$49(\frac{22}{7} )$

$=154$

Subtract the area of the two triangles from the area of the whole circle.

$154-49=105$

The area of the shaded part is 105 cm². The total area of the shape is 154cm².

$\frac{105}{154} =\frac{15}{22}$

A person gets on and off a bathroom scale four times. The four readings (in pounds) are 148, 151, 150, and 152. Each time after

Ganezh [65]

Answer:

See explanation below

Step-by-step explanation:

Since each time after the person gets off the scale, the reading is 2 lb the person's weight must be near the mean of

148-2, 151-2, 150-2, 152-2; that is to say, near the mean of 146, 149, 148, 150 = (146+149+148+150)/4 = 148.25

We could estimate the uncertainty as the standard error SE

$\bf SE=\frac{s}{\sqrt{n}}$

where

s = standard deviation of the sample

n = 4 sample size.

Computing s:

$\bf s=\sqrt{\frac{(146-148.25)^2+(149-148.25)^2+(148-148.25)^2+(150-148.25)^2}{4}}=1.479$

So, the uncertainty is 1.479/2 = 0.736

It is not possible to estimate the bias, since it is the difference between the true weight and the mean, but we do not know the true weight.

Does anyone know the answer ??

pickupchik [31]

Answer:

Y+5=2(x+1) if (5,10)

10+5=2(5+1)

15=2(6)

15=12

Y+5=2(x+1) if (-1,-5)

-5+5=2(-1+1)

0=2(0)

0=0
