Answer:
3 minutes and 42 seconds
Step-by-step explanation:
So I would convert that minute into seconds
7*60=420
So 420+24=444
Divide by 2
444/2=222
Now divide by 60 to convert it back to minutes
222/60= 3.7
3.7 minutes or
7/10*60=42
3 minutes and 42 seconds

2a - 3b = -11
a + 3b = 8
Answer:
b = 3 and a = -1
Step-by-step explanation:
You have your given equation:
2a - 3b = -11
a + 3b = 8
You need to find what a and b is.
To find b:
2a - 3b = -11
-2a - 6b = -16
I multiplied a + 3b = 8 by -2. When you multiply a number you have to multiply all of them. You have to choose a number that would cancel out all of a.
So now your equation would look like this when you solve for b:
2a - 3b = -11
-2a - 6b = -16
-------------------
a - 9 = -27 then you divide -9 to -27 which is 3 so b = 3.
To find a:
2a - 3b = -11
a + 3b = 8
I multiplied a + 3b = 8 by -1 and 2a - 3b = -11 by -1 as well.
Your equation will look like this when you solve for a:
-2a + 3b = 11
-1a - 3b = -8
------------------
-3a = 3 then divide -3 to 3 which is -1 so a = -1.
Check to see if you have the correct answer by plugging in the number you got for a and b into the equation and solve.
1. 2(-1) -3(3) = -11
-2 - 9 = -11
2. -1 + 3(3) = 8
-1 + 9 = 8

Find the value of x.
Answer:
x=34 degrees
Step-by-step explanation:
since angle TSU=4x then angle RSP=4x
4x-3x=x
angle PSQ=x
angle PQS=112 degrees (180-68=112)
triangle PSQ angles are x+x+112=180
2x-68
x=34 degrees
On a coordinate plane, the vertices of a rectangle are (–1, 1), (3, 1), (–1, –4), and (3, –4). What is the perimeter of the rectangle?
Given that,
The vertices of a rectangle are (–1, 1), (3, 1), (–1, –4), and (3, –4).
To find,
The perimeter of the rectangle.
Solution,
Let the points are :
A(–1, 1), B(3, 1), C(3, –4) and D(–1, –4)
Let's find AB and BC using distance formula :
[tex]AB=\sqrt{(3-(-1))^2+(1-1)^2} \\\\=4\ \text{units}[/tex]
[tex]BC=\sqrt{(3-3)^2+(-4-1)^2} \\\\=5\ \text{units}[/tex]
The perimeter of a rectangle = 2(sum of two adjacent sides)
= 2(AB+BC)
= 2(4+5)
= 18 units
So, the perimeter of the rectangle is 18 units.

Given: f(x) = 1/x+5 and g(x) = x - 2.
What are the restrictiorts of the domain of f(g(x))?
0 x4 -5
O X-3
OX= 2
There are no restrictions.
Answer:
The restriction of the domain of f(g(x)) is that x cannot be 3.
Step-by-step explanation:
The first step to solve this question is finding the function, replacing the values. So
[tex]f(x) = \frac{1}{x+5}[/tex]
[tex]g(x) = x - 2[/tex]
[tex]f(g(x)) = f(x - 2) = \frac{1}{x - 2 + 5} = \frac{1}{x - 3}[/tex]
The function is a fraction, which means that the restriction is that the denominator cannot be zero. So
[tex]x - 3 \neq 0[/tex]
[tex]x \neq 3[/tex]
The restriction of the domain of f(g(x)) is that x cannot be 3.
what is the sign of f on the interval -5
Answer:
f(x) = x3 - 3x + 1
f'(x) = 3x2 - 3 = 3(x2 - 1) = 3(x+1)(x-1)
Find the critical numbers: set f'(x) = 0
3(x+1)(x-1) = 0 x = 1, -1
Check the sign of f'(x) on either side of each critical number. If f'(x) is positive on an interval, then f is increasing on the interval. If f'(x) is negative on an interval, then f is decreasing on the interval.
+ l - l + sign f'(x)
-------------------------------------
-1 1
f is increasing on (-∞, -1) υ (1, ∞)
f is decreasing on (-1, 1)

express 28x-35y=-7,inthe form ax+by+c=0and find the value of a,b,&c
Answer:
a = 28, b = -35 and c =7
Step-by-step explanation:
Given expression is :
28x-35y=-7
We need to express it in the form of ax+by+c=0 and then find the value of a,b and .
Adding 7 to both sides.
28x-35y+7=-7+7
28x-35y+7=0
or
28x+(-35y) +7=0
It is in the form of ax+by+c=0.
On comparing,
a = 28, b = -35 and c =7

-x+y=-2 in slope intercept form
Answer:
y = x - 2
Step-by-step explanation:
Slope intercept form is: y = mx + b, where m is the slope and b is the y- intercept. In this question, we are given everything, and all we need to do is rearrange the terms.
-x + y = -2
Add x to both sides
y = x - 2
In this equation, the slope is 1 and the y intercept is -2.
Answer:
Step-by-step explanation:
Y = mx + b
Y = x -2 after adding x to both sides of equation
m = 1 and b = -2
