Y=2x+4
the y intercept is 4 and the slope is 2/1
Answer:
560,000L
Step-by-step explanation:
Given data
L=14m
W=8m
H=5m
Volume= L*W*H
Volume= 14*8*5
Volume= 560 m^3
1m^3 = 1000L
560m^3 = x
cross multiply
x= 560*1000
x= 560,000L
Hence the volume is 560,000L
To get the vertex of the parabola we proceed as follows;
y=-7(x-4)^2-5
The above can be written as:
y=-7x^2+56x-117
The values of a,b and c are:
a=-7, b=56 and c=-117
x=-b/(2a)
x=-56/(-7*2)=4
but;
y=-7x^2+56x-117
y=-7(4)^2+56(4)-117
y=-5
Thus;
x=4 and y=-5
The vertex will be at point (4,-5)
For all of these you're trying to solve for the variable. The variable is usually a number or symbol.
11) -44+n=36
Step one would be to add 44 to both sides of the equation.
N=80
12) -36=p-91
Step one would be to add -91 to both sides of the equation.
P=55
13) X-225=671
Step one you be to add 225 to both sides of the equation. Although it may seem difficult because of the big numbers, it's the same technique.
14) 19=c-(-12)
Step one on this equation will be a little different. Because there are two negative signs (-), they turn into a plus sign. Remember, two negative signs make a positive sign.
19=c+12
Now you just subtract 12 from each side of the equation.
6=C
Answer:
3
Step-by-step explanation:
3 x 2 = 6
6 + 4 = 10
10<12
Hope this helps!
