2x = 8 - 5y
x = 8/2 - 5y/2
x = 4 - 2.5 y
or
x = 4 - 5/2 y
7x12= 84
1+6=7
12=12
So the area is 84
Think about it... if the number is bigger than 5 you round up so.. 399 is rounded to 400.
Answer:
Step-by-step explanation:
The transformation from the parent function (red line) to the blue line is a translation 2 units to the left and 3 units down, and a reflection over the x-axis.
The blue line does not seem to be stretched or compressed.
Answer:
k = 13The smallest zero or root is x = -10
Step-by-step explanation:
you can write "x^2" to mean "x squared"
f(x) = x^2+3x-10
f(x+5) = (x+5)^2+3(x+5)-10 ... replace every x with x+5
f(x+5) = (x^2+10x+25)+3(x+5)-10
f(x+5) = x^2+10x+25+3x+15-10
f(x+5) = x^2+13x+30
Compare this with x^2+kx+30 and we see that k = 13
Factor and solve the equation below
x^2+13x+30 = 0
(x+10)(x+3) = 0
x+10 = 0 or x+3 = 0
x = -10 or x = -3
The smallest zero is x = -10 as its the left-most value on a number line.
