Answer: 1) 8x + 2 = 90 1a. 11 2. 13x-10= 133 2a. 11
Both solve for 11.
Step-by-step explanation: 1) they’re both the same measure so they equal each other
Subtract 2 from each side 8x = 88 and x is 11
13x - 10 = 133 they’re both the same measures so they equal each other.
Add 10 to both sides because it’s already negative and 13x = 143 and you get 11
Given:
The graph of a quadratic function passes through the points (5,31) (3,11) (0,11).
To find:
The equation of the quadratic function.
Solution:
A quadratic function is defined as:
...(i)
It is passes through the point (0,11). So, substitute 
in (i).
Putting 
in (i), we get
...(ii)
The quadratic function passes through the point (5,31). So, substitute 
in (ii).
Divide both sides by 5.
...(iii)
The quadratic function passes through the point (3,11). So, substitute 
in (ii).
Divide both sides by 3.
...(iv)
Subtracting (iv) from (iii), we get
Putting 
in (iv), we get
Putting 
in (ii), we get
Therefore, the required quadratic equation is .
Length (L): 4w - 7
width (w): w
Perimeter (P) = 2L + 2w
136 = 2(4w -7) + 2(w)
136 = 8w - 14 + 2w
136 = 10w - 14
150 = 10w
15 = w
Length (L): 4w - 7 = 4(15) - 7 = 60 - 7 = 53
Answer: width=15 m, length=53 m
sorry if it is wronged the answer is D
Answer:
$234
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 3%/100 = 0.03 per year,
then, solving our equation
I = 2600 × 0.03 × 3 = 234
I = $ 234.00
The simple interest accumulated
on a principal of $ 2,600.00
at a rate of 3% per year
for 3 years is $ 234.00.
