So you know if a and b are the numbers that a+b=36 and a-b=4 so you can solve one I solved the second equation for a a=4+b and plugging that a value into equations gives you 4+b+b=36
This simplified to 4+2b=36
2b=32
B=16 so you know one number is 16 and you can plug it in to find a a-16=4 so a=20
Therefore the two numbers are 16 and 20
Create a proportion: 4/7=x/392
Cross multiply: 7x=1568
Divide: 1568/7=224
x=224
Answer:
Step-by-step explanation:
We are given the following in the question:
Height of triangle,h = 4 inches
Area of triangle =
where b is the base of the triangle and h is the height of the triangle.
The area of the triangular sign must be less than 18 square inches.
Thus, we can write the inequality:
The above inequality is the required inequality that describes the possible base length of the triangular sign.
Answer:
Step-by-step explanation:
The slope formula is M=y2-y1
______
X2-X1
Ex. (-1,1) and (1,-2)
x1,y1 x2,y2
-2+1 -3
_____= ____
1+(+1) 2
Graph:
Any linear function can be quickly graphed using the form: y=mx+b
X: independent variable
y: dependent variable
M: slope
b: y-intercept
(When you don't have a denominator for M put a 1 Ex. 4--> 4/1)
Ex. y=-1/2x + 4
M= 1/2
B: 4
Rise/Run = -1/2 "rise" (being the change in y, going up or down) divided by the "run" (being the change in x, going from left to the right).
Answer: 270°
Step-by-step explanation:
A full rotation is 360° so to find out the clockwise equivalent of a 90° counterclockwise rotation, deduct the counterclockwise rotation from 360°:
= 360 - 90
= 270°
<em>If you rotated 90° counterclockwise, you would get to the same point as if you rotated 270° clockwise. </em>
