The x-intercept of the graph is the x-point where graph touches the x-axis. ... Here graph touches the x-axis two times. (c) (–1, 2) and (1, 0): x-intercept are -1 and -1.
Answer:
The answer is -32
Step-by-step explanation:
g(-5) = (-5)-1= -6
f(-6) = 2(-6)-20
f(-6) = -12-20
-32
From the two right triangles, you can write the following equations using the Pythagorean theorem. Let's call that shared leg in the middle "y"
y^2 + b^2 = a^2
y^2 + c^2 = x^2
y^2 + b^2 = a^2
re-write this to get "y" alone for substitution.
y^2 = a^2 - b^2
substitute (a^2 - b^2) for y^2 in the other equation. y^2 + c^2 = x^2
a^2 - b^2 + c^2 = x^2
Now put in the values given for a,b,c to solve for x
(7.1)^2 - (5.6)^2 + (5.7)^2 = x^2
51.54 = x^2
square root
7.2 = x
Answer:
Number of $10 bills = 2
Number of $5 bills = 3
Number of $1 bills = 5
Step-by-step explanation:
Given:
Total amount = $40
Number of $10 bills = x
Number of $5 bills = x + 1
Number of $1 bills = x + 1 + 2 = x + 3
Find:
Number of each bills
Computation:
10(x) + 5(x+1) + 1(x+3) = 40
10x + 5x + 5 + x + 3 = 40
16x = 32
x = 2
Number of $10 bills = x = 2
Number of $5 bills = x + 1 = 3
Number of $1 bills = x + 3 = 5
Answer:
<em>1. W = 50 ft</em>
<em>2. L = 110 m</em>
<em>3. L = 61 m</em>
Step-by-step explanation:
<u>Area of a Rectangle</u>
Given a rectangle of width W and length L, its area is calculated by the formula:
A = W.L
We are given three rectangle-shaped figures and are required to find different measures as explained below.
1. Length L=94 ft, Area = 4,700 square ft
We'll find the width by solving for W:


W = 50 ft
2. A=8,250 square m, W=75 m
We'll find the length by solving for L:


L = 110 m
3. A=1,586 square m, W=26 m
We'll find the length by solving for L:


L = 61 m
