Megan and Heidi are making cookies for an upcoming bake sale. Megan is making chocolate chip cookies and Heidi is making sugar c

koban [17]

Answer:

Heidi (260 cookies)

Step-by-step explanation:

Megan's equation is given as y=8x, where x is the number of bags, and y the number of cookies:

#First calculate Heidi's total number of bags, cookies and cookies:

$H_b=\sum{bags}\\\\=10+12+14+16\\\\=52 \ bags\\\\H_c=\sum{cookies}\\\\=50+60+70+80\\\\=260 \ cookies$

#Given that both Heidi and Megan make the same number of bags of cookies, Megan's cookies totals to:

$H_b=M_B=52 \ Bags\\\\M_c=y=8x, x=52\\\\y=8\times 52\\\\=416\\$

Hence, Megan makes 416 cookies.

#From our calculations:

$416>260\\\\M_c>H_c$

Hence, Heidi makes the least number of cookies(260 cookies) compared to Megan's 416 cookies.

the straight line L, has equation y=3x-4 The straight line 1, in perpendicular to L, and passes through the point (9.5) Find an

kari74 [83]

Given:

The equation of given line is

$y=3x-4$

A line is perpendicular to the given line and passes through the point (9,5).

To find:

The equation of the perpendicular line.

Solution:

We have,

$y=3x-4$

On comparing this equation with slope intercept form $y=mx+b$ , we get

$m=3$

It means, the slope of the given line is 3.

The product of slopes of two perpendicular lines is -1.

$m\times m_1=-1$

$3\times m_1=-1$

$m_1=-\dfrac{1}{3}$

Point slope form of a line is

$y-y_1=m(x-x_1)$

Where, m is the slope.

The slope of perpendicular line is $-\dfrac{1}{3}$ and it passes through the point (9,5). So the equation of the line is

$y-5=-\dfrac{1}{3}(x-9)$

$y-5=-\dfrac{1}{3}(x)-\dfrac{1}{3}(-9)$

$y-5=-\dfrac{1}{3}x+3$

Adding 5 on both sides, we get

$y-5+5=-\dfrac{1}{3}x+3+5$

$y=-\dfrac{1}{3}x+8$

Therefore, the equation of required line is $y=-\dfrac{1}{3}x+8$ .
