Answer:
50 minutes
Step-by-step explanation:
x=9
(5x9+5)+9+13=72
50+9+13=72
59+13=72
5x9=45
45+5=50
Well, to solve, garph the equation y=x^2+2x-8 and y=0
see where they intersect
anyway the easier way is to factor but anyway
0=(x-4)(x+2)
anyway
solution is x=4 and -2
A and D are answers (they are same)
Okay, so Sang is standing 20 yards away from one corner, and Jazmin is standing 99 yards away from the same corner. If this is a rectangle (I like visuals, so I'll use them to explain), then:
99ft
A ------------------------- B
| |
20 ft | |
| |
C -------------------------- D
The question is asking you to solve for the diagonal line between points C and B. If you imagine a line there, you actually have the rectangle split into two triangles. So if you have triangle ABC, side CB would be the longest line, or the hypotenuse. That means you can use the Pythagorean Theorem to solve the problem.
A^2 + B^2 = C^2
99^2 + 20^2 = C^2
9,801 + 400 = C^2
10,201 = C^2
Now you solve for the square root of 10,201 to get C.
sqr (10,201) = C
C = 101 yards
Answer:
3
Step-by-step explanation:
The diagonal line on the left decrements first by 13, then 11, then 9, then 7, which means for row 1 it decrements by 5. 8-5=3. The number is also 3 when you look at the diagonal line on the right. It starts on the bottom as decrements of 15, then 13, then 11, then 9, and finally 7. 10-7=3.
Answer:
Step-by-step explanation:
first graph
<h2>height=constant* width ( direct variation describes a linear relation between 2 variable )</h2>
6=8x ⇒ x=6/8=0.75
h=0.75w
<h2>constant is 0.75</h2>
second graph:
<h2>height=constant/width ( inverse variation)</h2>
15=x/4 ⇒x=4*15 ⇒x=60
<h2>constant=60</h2>
For two quantities with inverse variation, as one quantity increases, the other quantity decreases. k(constant)=xy
