It is not an integer because it isn’t a whole number.
Rosa earned $50
Explanation:
Two people Rosa & her brother
Her brother earns X
While Rosa earns 2X + 8
Now we gotta solve for X
They made $71. $71 minus X should give you Rosa’s pay
71 - X = 8 + 2X (subtract 8 from 71)
63 - X = 2X (add X to 2X)
63 = 3X (divide by 3)
21 = X
Plug in $21 for Rosa:
8 + 2(21)
8 + 42 = $50
Answer: (F)
Step-by-step explanation:
Answer:
A. f(x)= -(x-3)^(2)-2
Step-by-step explanation:
graphing the parabola, using the direction, vertex, focus, an axis of symmetry, we see that the direction it opens is down, like the picture shows. The vertex is at (3, -2), focus is (3,-9/4), axis of symmetry is x=3, and the directrix is y = -7/4 just as the picture shows. Therefore, A is the correct answer.
Hope this helps!!
The slope is change in "Y" divided by the change in "x"
1-(-3)/2-(-1)
= 4/3
Standard Form
y-y1=m(x-x1)
y-(-3)=4/3(x-(-1)
y+3=4/3x+4/3
y=4/3x-5/3
Rewrite in standard form
-4/3x+y=-5/3
Can't have fractions so multiply by 3 to get rid of the denominator
-4x+3y=5
Divide by -1 to get rid of the negative sign
4x-3y=-5
