What is the result of subtracting the second equation from the first? \begin{aligned} -7x-y &= 0 \\\\ 7x+8y &= -6 \end{a

Kitty [74]

Answer:

$-14x-9y=6$

Step-by-step explanation:

We are given with two equations

first equation is $-7x-y=0$

second equation is

$7x+8y=-6$

we find the result of subtracting two equation

subtract the second equation from the first, so

first equation - second equation, multiply second equation by -1 and then add it with first equation

$-7x-y=0$

$-7x-8y=+6$

Now add both equations, we get

$-14x-9y=6$

use the circle graph show below to answer the question a pie chart labeled favorite sports to watch is divided into into three p

mart [117]

From the pie chart described, the percent of people that responded that football was their favorite sport to watch is 42% which represents 210 of the people surveyed.

Let the number of people surveyed be x, then

$42%\ of\ x=210 \\ \\ \Rightarrow0.42x=210 \\ \\ \Rightarrow x= \frac{210}{0.42} =500$

Therefore, the number of people surveyed is 500 people.

For problems 29 - 31 the graph of a quadratic function y=ax^2 + bx + c is shown. Tell whether the discriminant of ax^2 + bx + c

Elan Coil [88]

Answer:

29) discriminant is positive

30) discriminant is 0

31) discriminant is negative

Step-by-step explanation:

the graph of a quadratic function y=ax^2 + bx + c is shown. Tell whether the discriminant of ax^2 + bx + c = 0 is positive, negative, or zero.

In the graph of question number 29 we can see that the graph intersects the x axis at two points

so the equation has 2 solutions.

When the equation has two solution then the discriminant is positive

In the graph of question number 30 we can see that the graph intersects the x axis at only one point

so the equation has only 1 solution.

When the equation has only one solution then the discriminant is equal to 0

In the graph of question number 30 we can see that the graph does not intersects the x axis

so the equation has 2 imaginary solutions.

When the equation has two imaginary solutions then the discriminant is negative
