Answer:
7 inches
Step-by-step explanation:
The ratio of width to length of the known rectangle is 4 : 14 and this simplifies to 2 : 7.
The smaller similar rectangle will have the same ratio of 2 :7.
This can also be looked at another way. The second value in the ratio is 7/2 of the first value in the ratio and the first value is 2/7 of the second value.
Example:
7/2 * 2 = 7
Example:
2/7 * 7 = 2
You need to solve for x (get x by itself)
x - 18 = -5 Add 18 on both sides
x - 18 + 18 = -5 + 18
x = 13
Answer:
Step-by-step explanation:
Here the coefficients of this quadratic are a = 1, b = 6 and c = 4.
-b
The axis of symmetry is x = -------- , which here is x = -6/2, or x = - 3.
2a
Use the given quadratic to find the vertical coordinate of the vertex:
y = (-3)^2 + 6(-3) + 4 = 9 - 18 + 4 = y = -5.
The axis of symmetry is x = -3, and the vertex is (-3, -5).
Answer:
the slope is 4/5
Step-by-step explanation:
well the slope formula is the following:
m= (change in y)/(change in x)
let's take the two following points
(-3,0) and (2,4) so
so
change in y =
change in x =
so
m=4/5
