Answer:
150 in
Step-by-step explanation:
Jeff modeled the number of minutes that he read each day during the first week of the summer. The recursive function, f(x), can be used to determine the number of minutes that he had read after a certain number of days, where x represents the number of days. f(1) = 28 f(x) = f(x - 1) + 8 Use the recursive function to find the number of minutes that Jeff read after 3 days of summer.
9514 1404 393
Answer:
44 minutes
Step-by-step explanation:
We are given f(1) = 28.
Using the recursive formula ...
f(2) = f(1) +8 = 28 +8 = 36
f(3) = f(2) +8 = 36 +8 = 44
Jeff read 44 minutes after 3 days of summer.

On a very cold morning, it was -7°F. As the day went on, the temperature rose 3 degrees each hour. Which equation shows the temperature over time?
A.y=-3x-7
B.y=-3x+7
C.y=3x-7
D.y=3x+7
Answer:
The equation shows the temperature over time will be:
[tex]y = 3x - 7[/tex]Hence, option (C) is correct.
Step-by-step explanation:
We know that the slope-intercept form of the line equation is
[tex]y=mx+b[/tex]
where m is the rate of change or slope and b is the y-intercept
Let 'y' be the temperatureLet 'x' be the time in the hour
Given that one very cold morning, it was -7°F.
Thus, the y-intercept = b = -7
Given that as the day went on, the temperature rose 3 degrees each hour.
Thus, the rate of change = slope = m = 3
Thus, substituting m = 3 and b = -7 in the equation
[tex]y = mx+b[/tex]
[tex]y = 3x + (-7)[/tex]
[tex]y = 3x - 7[/tex]
Therefore, the equation shows the temperature over time will be:
[tex]y = 3x - 7[/tex]Hence, option (C) is correct.
3415 base 7 ×(-432base 7)
Ignore the negative sign, since that only affects the sign of the final product
3415₇ × 432₇
You can compute the product by considering the digit expansion, by which I mean first expanding each number as sums of powers of 7:
3415₇ = 3000₇ + 400₇ + 10₇ + 5₇
(It's the same thing as writing, for example, the decimal 3415 as 3000 + 400 + 10 + 5, just in a different base.)
Similarly,
432₇ = 400₇ + 30₇ + 2₇
Then apply the distributive property:
= (3000₇ + 400₇ + 10₇ + 5₇) × (400₇ + 30₇ + 2₇)
= 3000₇ × (400₇ + 30₇ + 2₇)
… + 400₇ × (400₇ + 30₇ + 2₇)
… + 10₇ × (400₇ + 30₇ + 2₇)
… + 5₇ × (400₇ + 30₇ + 2₇)
= {12}00000₇ + {9}0000₇ + 6000₇
… + {16}0000₇ + {12}000₇ + {8}00₇
… + 4000₇ + 300₇ + 20₇
… + {20}00₇ + {15}0₇ + {10}₇
where I use the curly braces to indicate products (written in base 10) of digits that exceed 6. Anything in these braces needs to be properly converted to base 7. For example,
{12}₇ = 7 + 5 = 15₇
So you would have
= 1500000₇ + 120000₇ + 6000₇
… + 220000₇ + 15000₇ + 1100₇
… + 4000₇ + 300₇ + 20₇
… + 2600₇ + 210₇ + 13₇
Add everything up:
• In the 7⁰ place,
3₇
• In the 7¹ place,
1₇ + 1₇ + 2₇ = 4₇
• In the 7² place,
2₇ + 6₇ + 3₇ + 1₇ = {12}₇ = 15₇
• Carry the 1 (underlined). In the 7³ place,
2₇ + 4₇ + 1₇ + 5₇ + 6₇ + 1₇ = {19}₇ = 25₇
• Carry the 2. In the 7⁴ place,
1₇ + 2₇ + 2₇ + 2₇ = {7}₇ = 10₇
• Carry the 1. In the 7⁵ place,
2₇ + 1₇ + 5₇ + 1₇ = {9}₇ = 12₇
• Carry the 1. In the 7⁶ place,
1₇ + 1₇ = 2₇
So, we end up with
3415₇ × 432₇ = 22045543₇
and thus
3415₇ × (-432₇) = -22045543₇

Evan is making a table that will be created of the figure below. The table top is a triangle attached to a rectangle. To purchase the right amount of paint he needs to know the area of the table top He can only spend 10 on paint which is enough to cover 150ft of surfaces area. What is the max length of the base of the the rectangle he can build
Answer:
23 ft
Step-by-step explanation:
The computation of the maximum length of the base of the triangle is as follows:
Area of triangle is = 4 × 6 ÷ 2
= 12 ft²
Now the maximum area of the rectangle is
= 150 - 12
= 138 ft²
L = ?
W = 6 ft
Area of rectangle is = L × W
L × 6 = 138
L = 138 ÷ 6
= 23 ft
factor the following
42x+28y
Answer:
To find the GCF, do the prime factorization of both numbers.
42 = 2 x 3 x 7
28 = 2 x 2 x 7
The GCF uses the numbers that appear in BOTH, 2 x 7 = 14 is the GCF of the numbers. There is no variable GCF because there isn't a variable that appears in both.
Taking out the GCF gives you:
14(3x + 2y)
Step-by-step explanation:
Answer:
14(3x + 2y)
Find the GCF.
It is 14.
Use the distributive property.
Then, multiply each term.

Find the values of a and b so that the linear system has the given solution.
Given Solution: (2, 1)
Equation 1: ax - by'= 4
Equation 2: bx - ay = 10
Answer:
The values are a=6, b=8
Step-by-step explanation:
System of Equations
We are given the system of equations:
ax - by = 4
bx - ay = 10
And it's known the solutions are: x=2, y=1.
Plugging in the solutions:
2a - b = 4 [1]
2b - a = 10 [2]
Now we have to solve the system above. Multiply [1] by 2:
4a - 2b = 8
Now we add with [2]:
3a = 18
a = 18/3 = 6
a = 6
From [2]:
2b - 6 = 10
2b = 16
b = 16/2 = 8
b = 8
The values are a=6, b=8

Answer:
Store A
Step-by-step explanation:
Store A
50/100=0.5
0.5×5=2.5
The watch will be 50-2.5=47.5
Store B
60/100=0.6
0.6×20=12
The watch will be 60-12=48
So the watch price in store A is better
Answer:
You should buy from Store A because you're paying $0.50 less than if you were to buy from Store B.
Step-by-step explanation:
First, don't subtract if it's a percentage. You will want to multiply to get the amount you're removing from the original price.
Let's look at Store A. $50 and 5% discount. 50 * 0.05 = 2.5. Remove 2.5 from 50.
50 - 2.5 = 47.5
When you buy from Store A, you will pay $47.5
Let's look at Store B. $60 and 20% discount. 60 * 0.20 = 12. Remove 12 from 60.
60 - 12 = 48
When you buy from Store B, you will pay $48
Ultimately, Store A is the best option because you're paying less.
