Step-by-step explanation:
When it says x = something, that basically means to replace the x with whatever it says x equals.
x = 0. Equation /. 3 x 0 = 0 + 1 = 1. Y = 1
x = -1. Equation/. 3 x -1 = -3 + 1 = -2. Y = -2
x = 2. Equation/. 3 x 2 = 6 + 1 = 7. Y = 7
Hope this helps!! (:
Answer:
8
Step-by-step explanation:
In 2 hours
1 cook makes 10 large cakes
24/10 = 2.4
You need 3 cooks to make the large cakes.
In 2 hours
1 cook makes 28 small cakes
130/28 = 4.64
You need 5 cooks to make the small cakes.
3 + 5 = 8
Answer: 8
Answer:
x = 10 Perimeter: 129
Step-by-step explanation:
FINDING X:
4x+7 = 5x -3
7 = x -3
10 = x
x = 10
PERIMETER:
4x + 7 + 5x - 3 + 4x - 5
Combine the "x" values
13x + 7- 3 - 5
Combine the numbers
13x - 1
13(10) -1
130 - 1
129
Answer:
a = 4
Step-by-step explanation:
a^2 + b^2 = c^2
a= ?
b= 3
c= 5 (c is always the hypotenuse)
*plug in given values
a^2 + 3^2 = 5^2
a^2 + 9 = 25
-9 -9
a^2 = 16
*find the square root
sqrt(a) = sqrt(16)
a = 4
Answer:
h= 4.6, c=7.1
Step-by-step explanation:
First you need to know in a 30 60 90 triangle the sides ratios are x, 2x and x√3, and for 45 90 45 it is x, x and x√2
so <em>h</em> is 8/√3 and you rationalize the bottom so it becomes 8√3/3. when you solve this and round to nearest hundred it becomes 4.6. for the second one, it is 5√2 and when you solve this and round, it becomes 7.1
