Answer:

24,138 pennies

Step-by-step explanation:

Step one:

given data

Fernanado saves a total of 8,046 pennies every two weeks

Required

the number of pennies saved in six weeks

Step two:

       If in 2 weeks he saved  8,046 pennies

then in  6 weeks he will save x pennies

cross multiply we have

2x= 6* 8,046

divide both sides by 2

x= 48276/2

x=24,138 pennies

Geometry:(<br><br> will give brainist to correct answer:)
Lorico [155]

Given:

End points a line segment are (9,-8) and (-1,-4).

To find:

The equation of perpendicular bisector of given line.

Solution:

Slope of given line is

m=\dfrac{y_2-y_1}{x_2-x_1}

m_1=\dfrac{-4-(-8)}{-1-9}

m_1=\dfrac{-4+8}{-10}

m_1=\dfrac{4}{-10}

m_1=-\dfrac{2}{5}

Product of slopes of two perpendicular line is -1.

m_1\times m_2=-1

(-\dfrac{2}{5})\times m_2=-1

m_2=\dfrac{5}{2}

So, slope of perpendicular bisector is \dfrac{5}{2}.

Perpendicular bisector passes through the midpoint of given endpoints.

Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)

Midpoint=\left(\dfrac{9+(-1)}{2},\dfrac{(-8)+(-4)}{2}\right)

Midpoint=\left(\dfrac{8}{2},\dfrac{-12}{2}\right)

Midpoint=\left(4,-6\right)

So, perpendicular bisector passes through (4,-6) and having slope \dfrac{5}{2}. The equation of perpendicular bisector is

y-y_1=m(x-x_1)

where, m is slope.

y-(-6)=\dfrac{5}{2}(x-4)

y+6=\dfrac{5}{2}(x)+\dfrac{5}{2}(-4)

y+6=\dfrac{5}{2}x-10

y=\dfrac{5}{2}x-10-6

y=\dfrac{5}{2}x-16

Therefore, the equation of perpendicular bisector is y=\dfrac{5}{2}x-16.

PLEASE HELP ITS MATH
faltersainse [42]

Answer:

y = 4x + 3

Step-by-step explanation:

as the line is parallel to the given equation, the gradient (4x) must stay the same, and as it must pass through the point (-2, -5), we can solve for the y intercept:

to calculate for the y intercept, it is best to express the equation in slope intercept form:

y = mx + b

in this equation, mx stands for the gradient, which ive already highlighted remains 4x, and b stands for the y intercept (which we don't know yet).

y = 4x + b

what we have been given instead is the coordinates for the point this line crosses through (-2,-5) meaning when x = -2, y = -5.

Using this information, we can replace x and y in the equation:

-5 = 4(-2) + b

with consideration to the order of operations, it is important to solve the brackets first

-5 = -8 + b

now to get b by itself add 8 to both sides of the equation:

-5 + 8 = -8 + 8 + b

3 = b

now we remember from the slope intercept equation, b = the y intercept, so we can now solve the equation.

y = 4x + b  

replace b with the number we solved for (3).

y = 4x + 3

this is the equation of the line that is parallel to y = 4x + 1, and passes through the point (-2, -5)

hope this helps :)

Pls help f(x)=2(x+1)^2+3
lidiya [134]

Answer:

y= 2x² + 2x +3

Step-by-step explanation:

y=f(x)

y=2( x^2 + 1^2 +2(x)(1) ) + 3

y=2x^2 + 1 + 2x +3

y= 2x^2 + 2x +3
