Answer:
5.4
Step-by-step explanation:
First work out 4/9 this is the same thing as 4 ÷ 9 which equals 0.44444
and then add the whole number 5 so,
5 + 0.44444 = 5.44444
X*5
x*<span>1
</span>5*x evaluates to 5x
Multiply 9 and 5x
Multiply 1 and x answer is 15x
The answer be will be 3.2
Answer:
1/3x +2/3 = y
Step-by-step explanation:
y= 3x-2
To find the inverse, exchange x and y
x = 3y-2
And solve for y
x+2 = 3y-2+2
x+2 = 3y
Divide by 3
1/3(x+2) = 1/3(3y)
1/3x +2/3 = y
Answer:
<u>Step-by-step explanation:</u>
Use the vertex formula: y = a(x - h)² + k where
- a is the vertical stretch
- -a is a reflection over the x-axis
- (h, k) is the vertex
We can see that the vertex of the curve is (-3, 4) --> h = -3, k = 4
and it is a reflection over the x-axis --> a-value is negative
We need to find the a-value. Choose another point on the curve and plug it into the vertex formula for (x, y) and then solve for a.
I will choose (x, y) = (-3/2, 0)
Now that we know the vertex and the a-value, we can input them into the vertex formula:
