Answer:
6.32 = 6.320
Step-by-step explanation:
Convert both to like decimal by adding 0 to the end. Then compare.
6.320 = 6.320
The line y=7 is a horizontal line with a slope of 0.
Slope intercept form of
y=mx+b
would be
y-y1=m(x-x1)
m=0 and point of (-1,-10)
y-(-10)=0
y=-10
Answer:
xy (less than or equal to sign) 4
Answer:
The value of y given the values of x and z in the question is -734.85
Step-by-step explanation:
This is a joint variation question.
First, we are made to know that y varies jointly as x and z.
The equation for this can be written as;
y = k * x * z
Where k is the constant of proportionality.
Let’s calculate k first.
117 = k * (-3) * (-11)
33k = 117
K = 117/33 = 3.55
Now, we proceed to get what y is when x = -9 and z = 23
Let’s plug these values into the initial equation written.
y = k * x * z
We use the value of k calculated above;
y = 3.55 * (-9) * (23) = -734.85
Answer:
10x
Step-by-step explanation:
<h3>Expression:</h3>
Length = x unit
Width = 4*x = 4x
Perimeter = 2*(length + width )
= 2*(x + 4x)
= 2 *5x
= 10x
