Answer:
We know that for a rectangle of length L and width W, the perimeter is:
P = 2*L + 2*W.
In this case, we know that:
P = 85ft = 2*L + 2*W
L = 2*(x + 16)
W = (3*x - 1)
(where i guess that these units are in ft )
This is a system of equations:
Then we can replace the second and third equation into the first one, and get:
85 = 2*2*(x + 16) + 2*(3x - 1)
And solve this for x, we will get:
85 = 4x + 64 + 6x - 2
85 - 64 + 2 = (4 + 6)*x
23 = 10*x
23/10 = x
2.3 = x
Then the measures of the rectangle are:
L = 2*(x + 16) = 2*(2.3 + 16) = 36.6
W = (3*x - 1) = (3*2.3 - 1) = 5.9
The length of the rectangle is 36.6 feet, (and the width is 5.9 feet)
Given the quadratic function y = x2 - 11x - 26, what interval
is this function negative.

x = 30
Plug back into angles:
m<1 = 2x
m<1 = 60 degrees
m<2 = x
m<2 = 30 degrees
write an equation in slope intercept form of the line that passes through the given point and is parallel to the graph of the given equation. (-7,-5);y= -4x+5)
Answer:
y=-4x-33
Step-by-step explanation:
Since the equation is parallel it will have the same slope which is -4
Now just plug in the points into the equation y=-4x+n
Plug them in and you get -5=-4(-7)+n
Then solve which will get you n=-33
Therefore the equation is y=-4x-33

Step-by-step explanation:
The sum of first nth terms of two APs are in the ratio (3n+8)
is to (7n+15).Find the ratio of their 12th terms
Sum of first n terms of two AP's are in the ratio (3n + 8) : (7n + 15).
Find:the ratio of their 12th terms
Solution:Let the first terms and common differences of the two APs be a , d & a' , d'.
We know that,
Sum of first n terms of an AP (Sn) = n/2 * [ 2a + (n - 1)d ]
So,
⟹ n/2 * [ 2a + (n - 1)d ] : n/2 * [ 2a' + (n - 1)d' ] = 3n + 8 : 7n + 15
⟹ 2a + (n - 1)d : 2a' + (n - 1)d' = 3n + 8 : 7n + 15
Multiply numerator and denominator by 1/2 in LHS
⟹ a + (n - 1)/2 * d : a' + (n - 1)/2 * d' = 3n + 8 : 7n + 15
Now,
3n + 8 : 7n + 15 is the ratio of nth terms of the two APs.
We have to find the ratio of 12th terms.
We know that,
nth term of an AP (aₙ) = a + (n - 1)d
⟹ a₁₂ = a + (12 - 1)d
⟹ a₁₂ = a + 11d
So,
⟹ a + (n - 1)/2 * d = a + 11d
⟹ n - 1/2 = 11
⟹ n - 1 = 22
⟹ n = 23
Hence, we have to substitute n as 23 to find the ratio of their 12th terms.
⟹ a + 11d : a' + 11d' = 3(23) + 8 : 7(23) + 15
⟹ a + 11d : a' + 11d' = 77 : 176
⟹ a + 11d : a' + 11d' = 7 : 16
∴ The ratio of the 12th terms of the two APs is 7 : 16.
I hope it will help you.

Michael works 6 days every month at his grandfather's store. His grandfather pays him the same amount each day. Let e represent the total amount earned during one month. Michael earned $252, write and evaluate the expression for when e = 252.
Answer:
$42 per day
Step-by-step explanation:
Michael works 6 days every month
His grandfather pays him the same amount each day.
Michael earned $252
e = $252
Amount Michael earns per day = Total amount earned in a month / number of days worked for in a month
= $252 / 6 days
= $42 per day
Jace practices the piano 798 minutes in 3 weeks. At what rate did she practice, in minutes per day?
Answer:
38 minutes each day
Step-by-step explanation:
Answer:
38 minutes per day
Step-by-step explanation:
The information given says that Jace practices 798 minutes in 3 WEEKS and we need to convert that to days. There are 7 days in a week so multiply
7 x 3 = 21
Now you have to divide the minutes by 21.
798 ÷ 21 = 38
Jace practices piano for 38 minutes every day.

If t(1) = 11 and t(3) = 17, then which value below is NOT part of the arithmetic sequence? 23 96 56 74
Answer:
96
Step-by-step explanation:
It appears that the rate of change for this sequence is +3 because since t(1) = 11 and t(3) = 17, it would make sense that t(2) = 14.
From there you can use a calculator and start from 17 and keep adding 3 until you notice a number that doesn't belong in the sequence.

Answer:
f(x) = { 3, 1, -1, -3 }
Step-by-step explanation:
f(x) = −2x + 5
when
x=1
f(1) =−2 * 1 + 5 = -2 + 5 = 3
x=2
f(2) = −2 * 2 + 5 = -4 + 5 = 1
x=3
f(3) = −2 * 3 + 5 = -6 + 5 = -1
x=4
f(4) = −2 * 4 + 5 = -8 + 5 = -3
