Answer:
Option C is correct.
Step-by-step explanation:
y = x^2-x-3 eq(1)
y = -3x + 5 eq(2)
We can solve by substituting the value of y in eq(2) in the eq(1)
-3x+5 = x^2-x-3
x^2-x+3x-3-5=0
x^2+2x-8=0
Now factorizing the above equation
x^2+4x-2x-8=0
x(x+4)-2(x+4)=0
(x-2)(x+4)=0
(x-2)=0 and (x+4)=0
x=2 and x=-4
Now finding the value of y by placing value of x in the above eq(2)
put x =2
y = -3x + 5
y = -3(2) + 5
y = -6+5
y = -1
Now, put x = -4
y = -3x + 5
y = -3(-4) + 5
y = 12+5
y =17
so, when x=2, y =-1 and x=-4 y=17
(2,-1) and (-4,17) is the solution.
So, Option C is correct.
Answer: IT IS BBBB
Step-by-step explanation:
In the figure attached, the complete question is shown.
Originally the scale is 1 inch: 12 yards, the width is 6 inches, that is, 6*12 = 72 yards, and the length is 9 yards, that is, 9*12 = 108 yards
If the scale is 1 inch: 36 yards, then 72 yards are:
1 inch / x inches = 36 yards / 72 yards
x = 72/36 = 2 inches
which represents the new width.
And 108 yards are:
1 inch / x inches = 36 yards / 108 yards
x = 108/36 = 3 inches
which represents the new length.
Step-by-step explanation:
the first one is 2 that appears most while the second is 20 and 3
The reflected function is g(x) = √(-x).
And the correct option is the third one.
<h3>
Which table represents the reflection?</h3>
Remember that for a function f(x), a reflection across the y-axis gives:
g(x) = f(-x).
In this case, the original function was:
f(x) = √x
Then we have:
g(x) = √(-x).
So we can only evaluate this function in values of x such that:
x ≤ 0.
Then the correct option is:
"On a coordinate plane, a graph starts at (0, 0) and goes to the left through (negative 4, 2)."
As when we evalute g(x) in -4, we get:
g(-4) = √(-(-4)) = √4 = 2

They're asking what number you need to multiply the first equation to get rid of the "y" variable. Since the second equation has 10y, we want the first equation to be "-10y". Therefore we want to MULTIPLY by -10.
