Answer: B
Step-by-step explanation:
To find the inverse function, you switch x with y and y with x. Then, you solve for y.
[switch x with y, and y with x]
[add both sides by 4]
[square root both sides]
[add both sides by 1]
Now that we know the inverse function, we can actually tell that the answer is B. We know this because of the restriction that f(x) is x≤1. This makes it positive, and B the answer.
Answer: The points of the images are (9,10), (15,6), (6,4) and the image is not a rigid motion because the shape changes in side.
Step-by-step explanation:
Since it gives you the scale factor then find they coordinates by multiplying the coordinates by the scare factor.
A(3,5) → (3*3,5*2) → (9,10)
B( 5,3) → (5*3, 3*2) → (15,6)
C ( 2,3)→ (2*3, 2*2)→ ( 6,4)
If there is 10% of $18 = 18 x 0.9 (1 - 0.1) = $16.20
Therefore the pie costs $16.20
He is saving 18 - 16.20 = $1.80
We have to consider the Order of Operations
And Divide the question into different parts
So we first do the Exponent:
= 32
(3×32-26)=(96-26)=70
Solve the parts in parenthesis
(8-(4-9)=(8-(-5)=(8+5)=13 (minus and minus becomes addition)
Distribute 7
7(13)=91
Now put the equation and equate everything
(3×
+13(-2))+7(8-(4-9)=70+91=161
Final Answer=
161
Answer:
x= -1 (looks like C)
Step-by-step explanation:
To solve for x, factor the quadratic. Begin by factoring out a GCF of 5.
To factor the remaining parts of the quadratic, look for two factors of 5 which add to 6. This would be 1 and 5.
So the quadratic factored is:
To solve for x, set each factor equal to 0 and solve.
x+1 = 0
x = -1
x+5 = 0
x=-5
-1 is the largest solution.
