1. If m=1/2 and b=-4, what is the equation of the line?
Answer:
y=1/2x-4
Step-by-step explanation:
Vivienne has 5 pets, all of which are either birds or cats. Her pets have a total of 14 legs. Choose the system of equations that can be solved to find the number of birds that Vivienne owns, b, and the number of cats that Vivienne owns, e.
Answer:
the system of equations is
b + e = 5
2b + 4e = 14
and the solved system gets you to the conclusion that vivienne has 3 birds and 2 cats
Step-by-step explanation:
b is the amount of birds and e is the amount of cats so adding them together would give you 5, the total amount of pets. so this is the first equation:
b + e = 5
next, we know that birds have two legs and cats have 4, so those respective numbers times the amount of each animal will give you 14, the amount of legs. so the equation would be:
2b + 4e = 14
so the system of equations would be
b + e = 5
2b + 4e = 14
i wasnt sure if you also needed to solve it but here it is solved
b = 5 - e
2(5 - e) + 4e = 14
10 - 2e + 4e = 14
10 + 2e = 14
2e = 4
e = 2
so using subsitution you would get b by using the value of e in the first equation.
b = 5 - e
b = 5 - 2
b = 3
so vivienne has 3 birds and 2 cats.
The required number of birds and cats Vivienne have is 3 and 2 respectively.
What are simultaneous linear equations?Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.
Here,
Vivienne has 5 pets, all of which are either birds or cats.
Let the number of birds be x, and the number of cats be y,
x + y = 5, - - - - -(1)
Now, Her pets have a total of 14 legs. Since a bird has 2 legs and a cat has 4 lags
According to the question,
2x + 4y = 14 - - - - -(2)
Solving equations 1 and 2,
2x + 4 (5 -x) = 14
2x + 20 - 4x = 14
2x = 6
x = 3
Now,
3 + y = 5
y = 2
Thus, the required number of birds and cats Vivienne have is 3 and 2 respectively.

A company has recently been hiring new employees. Today the company has 33% more employees than it did a year ago. If there are currently
53,200 employees, how many employees did the company have a year ago?
Answer:
Sorry , I might be wrong : 35664
Step-by-step explanation:
So, first, we can find 33% of 53,200
That is 17,556
Then, we can subtract 17556 from 53,200
We get 35664

Triangle CAT is an isosceles triangle with base angles C and T each represent by (3x + 11) degrees, while angle A is represented by (9x + 8) degrees. Find the measure of angle C.
Answer:
Angle C = 41°
Step-by-step explanation:
Given:
Angle C = (3x + 11) degree
Angle T = (3x + 11) degree
Angle A = (9x + 8) degree
Find:
Angle C
Computation:
Using angle sum property
(3x + 11) + (3x + 11) + (9x + 8) = 180
15x + 30 = 180
x = 10
So,
Angle C = (3x + 11) degree
Angle C = 3(10) + 11
Angle C = 41°

What is the rate of change in the price of the washer-and-dryer pair between Week 1 and Week 57
$11.45
week
59. 16/week
0 59. 16/week
$11.45
week
Answer:
The answer is A. -11.45
Step-by-step explanation:
By using expression for the rate of change in prices between week 1 and week 5 will be -$11.45.
Rate of change is given by the expression,
Rate of change = [tex]\frac{\triangle y}{\triangle x}[/tex]
= [tex]\frac{\text{Change in price}}{\text{Change in weeks}}[/tex]
By using the given expression, rate of change of prices between week 1 and week 5 will be,
Rate of change = [tex]\frac{694.99-740.79}{5-1}[/tex]
= [tex]-\frac{45.8}{4}[/tex]
= [tex]-11.45[/tex]
Therefore, rate of change in the price of washer and dryer pair between week 1 and week 5 will be -$11.45 per week.

Which expression is a factor of 21 x2 + 13 x-20
Answer:
(7x−5)(3x+4)
Step-by-step explanation:
I think this is the answer
Answer:
(7x−5)(3x+4)
Step-by-step explanation:
Step-1 : Multiply the coefficient of the first term by the constant -21 • 20 = -420
Step-2 : Find two factors of -420 whose sum equals the coefficient of the middle term, which is 13 .
-420 + 1 = -419
-210 + 2 = -208
-140 + 3 = -137
-105 + 4 = -101
-84 + 5 = -79
-70 + 6 = -64
-60 + 7 = -53
-42 + 10 = -32
-35 + 12 = -23
-30 + 14 = -16
-28 + 15 = -13
-21 + 20 = -1
-20 + 21 = 1
-15 + 28 = 13 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -15 and 28
-21x2 - 15x + 28x + 20
Step-4 : Add up the first 2 terms, pulling out like factors :
-3x • (7x+5)
Add up the last 2 terms, pulling out common factors :
4 • (7x+5)
Step-5 : Add up the four terms of step 4 :
(-3x+4) • (7x+5)
