Answer:

x = 3

y = 2

Step-by-step explanation:

Equations

7x - 7y = 7

-4x - 7y = - 26 Multiply both sides of the equation by - 1

-1(-4x - 7y = - 26)

4x + 7y = 26

Solution

Add the two equations together

7x - 7y = 7

4x + 7y = 26

11x = 33 Divide by 11

11x/11 = 33/11

x = 3

4x + 7y= 26 Use this equation to solve for y. Use x = 3

4*3 + 7y = 26 Combine the left

12 + 7y = 26 Subtract 12 from both sides

12 - 12 + 7y = 26 - 12 Combine

7y = 14 Divide by 7

7y/7 = 14/7

y = 2

The bakers at Healthy Bakery can make 270 bagels in 10 hours. How many bagels can they bake in 15 hours? What was the rate per h

Tcecarenko [31]

Answer:

405 bagels 27 an hour

Step-by-step explanation:

this is because when you divide 270 by 10 you get 27 which is how much per hour then multiply the # of bagels and the # of hours you get is 405. In other words you first want to know how many bagels it took to get to 270 bagels in 10 hours.Hope it helped.

Whats the roots of the following three problems:

klemol [59]

QUESTION 1

The given function is

$f(x)=\frac{(x-3)(x-1)}{(x-1)(x+2)}$

We simplify to get;

$f(x)=\frac{x-3}{x+2}$

This function is equal to zero when $x-3=0$

$\Rightarrow x=3$

QUESTION 2

The given function is

$f(x)=\frac{5x^2-10x+5}{2x^2-5x+3}$

$f(x)=\frac{5(x^2-2x+1)}{2x^2-5x+3}$

We factor to get;

$f(x)=\frac{5(x-1)^2}{(2x-3)(x-1)}$

$f(x)=\frac{5(x-1)}{(2x-3)}$

This function equals zero when

$5(x-1)=0$

$x=1$

QUESTION 3

The given function is

$f(x)=\frac{x^3-8}{x^2-6x+8}$

We factor to get,

$f(x)=\frac{(x-2)(x^2+2x+4)}{(x-2)(x+4)}$

$f(x)=\frac{x^2+2x+4}{x+4}$

The function equals zero when $x^2+2x+4=0$

$D=b^2-4ac$

$D=2^2-4(1)(4)$

$D=-12$

Hence the equation has no real roots.

The complex roots are

$x=-\sqrt{3}i-1$ or $x=-1+\sqrt{3}i$

Leo drew a line that is perpendicular to the line shown on the grid and passes through point (F. G). Which of the following is t

tensa zangetsu [6.8K]

The equation of the perpendicular line drawn by Leo is $y-G=\dfrac{-1}{2}(x-F)$ . Option C is the correct answer.

<h3>How to determine the equation of a line?</h3>

A line is drawn perpendicular to the line shown in the image. The perpendicular line passes through the coordinate point (F,G).

The slope of the line from the graph is-

$m=\dfrac{y-intercept}{x-intercept}\\\\\\m=2$

Therefore, the slope of the perpendicular line is $\dfrac{-1}{2}$ .

Also, it is being given that Leo's line is passing through the coordinate point .

So, the equation of the Leo's line is-

$y-G=\dfrac{-1}{2}(x-F)$

Thus, the equation of the perpendicular line drawn by Leo is .

$y-G=\dfrac{-1}{2}(x-F)$
