Answer:
12/7 hoursStep-by-step explanation:
Lisa's rate is 1/3 of job per hour
Rachel's rate is 1/4 of job per hour
Their rate if worked together:
1/3 + 1/4 = 4/12 + 3/12 = 7/12 per hourJob will be done in:
1 : (7/12) = 12/7 hoursChoose the system for the graph
The answer will be A
q(x)= 1/2x - 3; q(x) =-4. Find the value of x
Answer:
[tex]q(x) =-5[/tex]
Step-by-step explanation:
I am solving this using Function Notation.
We are given:
[tex]q(x)= \frac{1}{2}x - 3[/tex]
While we are to find:
[tex]q(x) =-4[/tex]
In Function Notation, replace all the "[tex]x[/tex]" you see with the value you are given.
So, in this case,
[tex]q(x)= \frac{1}{2}x - 3\\\\=\frac{1}{2}x - 3[/tex]
Would become
[tex]q(x)= \frac{1}{2}x - 3\\\\=\frac{1}{2}(-4) - 3[/tex]
Now we can solve.
[tex]\frac{1}{2}(-4) - 3[/tex]
Use PEMDAS; Parenthesis first;
[tex]\frac{1}{2}(-\frac{4}{1})[/tex]
Cross divide: 1 cancels 1, -4 ÷ 2 = -2
Hence, we are left with
[tex](-2) - 3[/tex]
[tex]-5[/tex]
Therefore, the value of x is -5

b) 7 ≤ y
c) n ≤ 20
d) g ≥ 19
e) -5 < w
Step-by-step explanation:
Recognize the following English translations:
"no more than" means "less than or equal to" (≤)
"at least" means "greater than or equal to" (≥)
With these translations and the ones shown in your figure, you have ...
a) x > -2
b) 7 ≤ y
c) n ≤ 20
d) g ≥ 19
e) -5 < w
find the 21st term of the AP 1,3,5,7,
Answer:
are you Philippines ty points
Answer:
a₂₁ = 41
Step-by-step explanation:
The nth term of an AP is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 1 and d = a₂ - a₁ = 3 - 1 = 2 , then
a₂₁ = 1 + (20 × 2) = 1 + 40 = 41

A square with 20 meters shown as 12 centimeters, how long would a girder appear 15 meters long?
9.6 centimeters
EXPLANATION
20 meters = 12 centimeters
15 meters = x
20 meters/12 centimeters = 15 meters/x
20 meters/0,12 meters = 16 meters/x
1666.66 = 16 meters/x
x = 16 meters : 1666.66
x = 0.096 meters
x = 9.6 centimeters

Which expression is equivalent to 6f-1+7f-8?
13f+7 5f-1
-f+7 or -9+13f
Answer:
Step-by-step explanation:
6f - 1 + 7f - 8 = 6f + 7f - 1 - 8
= 13f - 9
Combine like terms. Like terms have same variable with same power.
Answer:
-9+13f
Step-by-step explanation:
6f+7f = 13f
-1 + -8= -9
So the sum of them is -9+13f

Answer 105.4 + 75 = 180.4
Instructions: Create a table of values for the given function.
Function: f(x) = -4x + 3
Answer:
Domain: {-2, -1, 0, 1, 2}
Range: {-5, -1, 3, 7, 11}
Step-by-step explanation:
Given the function, f(x) = -4x + 3:
We could simply substitute the given x-values into the function to solve for its corresponding y-values:
x = -2:
f(-2) = -4(-2) + 3
f(-2) = 8 + 3
f(-2) = 11
x = -1:
f(-1) = -4(-1) + 3
f(-1) = 4 + 3
f(-1) = 7
x = 0:
f(0) = -4(0) + 3
f(0) = 0 + 3
f(0) = 3
x = 1:
f( 1 ) = -4( 1 ) + 3
f( 1 ) = -4 + 3
f( 1 ) = -1
x = 2:
f(2) = -4(2) + 3
f(2) = -8 + 3
f(2) = -5

Please i need help :(
Answer:
Distributive property, Inverse Operation, and Division property of Equality
Step-by-step explanation:
Because 8•x is 8x and 8x3 is 24 so then the equation would be 8x-24=-40 then you have to add 24 on both sides to the 8x by itself and also get -16 which you would divide 8 on both sides to get x= -2
