Answer: Width will be 10 inches
and height will be 14 inches.
Explanation:
Since we have given that
The are of the triangular display case is 70 sq. in.
Let the width of the base be x
Let the height of the base be 2x-6
As we know the formula for " Area of triangle " i.e.
According to question,
Since width can't be negative so, we take width = 10 inches
And height is given by
Hence, width will be 10 inches
and height will be 14 inches.
I'm gonna say C )
We have to multiply the number outside the parenthesis by the numbers inside.
Answer:
(a) no
(b) -1, (2, -1)
(c) 4, (4, 7)
(d) no
Step-by-step explanation:
<h3>(a)</h3>
You can check by using x=3 in the function.
f(3) = 4(3) -9 = 12 -9 = 3 . . . . not -3
The point (3, -3) is not on the graph.
__
<h3>(b)</h3>
Put x=2 into the function and evaluate:
f(2) = 4(2) -9 = 8 -9
f(2) = -1
The point (2, -1) is on the graph.
__
<h3>(c)</h3>
Put f(x) = 7 into the equation and solve for x.
7 = 4x -9
16 = 4x
4 = x
The point (4, 7) is on the graph.
__
<h3>(d)</h3>
no, see part (b)
Answer:
<h3>1404</h3>
Step-by-step explanation:
To use the order of operations stands for (Parenthesis, Exponents, Multiply, Divide, Add, and Subtract) left to right. Please Excuse My Dear Aunt Sally!
BOMDAS stands for (Brackets, Of, Multiply, Divide, Add, and Subtract) from left to right.
First, do parenthesis.
52*(4+23)
4+23=27
52*27
Then, multiply.
52*27=1404
1404
The correct answer is 1404.
Answer:
you can see when you put x = -3 you get 0 for g(x)
so we can write g(x) = 3+x because if we put x to be -3 in this equation you get 0.
a. h(0) = f(0)g(0), g(0) = 3+0= 3
h(0) = f(0)x3, now In the graph f(x) we can see at x=0, y is -1.
now h(0) = -1x3 = -3 (answer)
b. (-infinity, +infinity) or (-2, inf) I'm not sure.
c. values that yeild h(x)=0 are; -3, 3, -1.
