Answer:
y (35y +8)
_______
60
Step-by-step explanation:
Hope this helps.
Answer:
Step-by-step explanation:
we know the slope is 15, and contains these points (-10,-5)
y=15x+b
Plug in x and y with those points.
-5=15(-10)+b
-5=-150+b
b=145
The equation is y=15x+145
Answer:
Step-by-step explanation:
Vertex form of a quadratic equation is: y = a(x - h)² + k, where point (h, k) is the vertex
f(x) = 3(x - 2)² + 11
This is in vertex form, so the vertex is (2, 11)
*it's positive 2 because we are subtracting h in the equation, and we are subtracting positive 2 in our problem
I would set the equations on top of each other and subtract
6x+y=21
- 3x-y=6
________
3x=15
Then solve for x
X=5
To solve for y, plug 5 in for x for one of the equations
In this question, the information that Katie has already read 32% of a book that has a total of 80 pages is of great importance. This information is enough to find the required answer to the question.
Total number of pages Katie has to read = 80
Percentage of pages that Cathie read = 32%
Number of pages that Katie read = (32/100) * 80
= 256/10
= 25.6 pages
Then
The number of pages that Katie have left to read = 80 - 25.6
= 54.4 pages
So Katie has 54.4 pages left to read.
