Answer:
312
Step-by-step explanation:
25+.15x=71.80
-25 -25
.15x=46.8
46.8/.15
x=312
Step-by-step explanation:
Given
3 ( x + 4) + 2 ( 5 - x)
= 3x + 12 + 10 - 2x
= x + 22

Answer:
To get the x-intercept we need the equation of the parabola;
the vertex form of the equation is given by:
y=a(x-h)^2+k
where:
(2,13) is the vertex:
Therefore;
y=a(x-2)^2+13
when x=0, y=5
Therefore the value of a will be:
5=a(0-2)^2+13
5-13=4a
4a=-8
a=-2
therefore the equation of the parabola will be:
y=-2(x-2)^2+13
y=-2x^2+8x+5
the x-intercept will be:
x=2-sqrt(7.5)
or
x=2+sqrt(7.5)

Step-by-step explanation:
and can u help me with my question if u can
Amswer:x= -41/20
Solutions:
(2x + 3)2 + 8(2x + 3) + 11 = 0
4x+6+16x+24+11=0
20x+41=0
20x=-41
x= -41/20
