Answer:
-2.25
Step-by-step explanation:
9(1-x) = 27Y
9-9x =27y
-9x -27y = -9 multiply all terms by -1
9x +27y =9 equation (1)
x-y= -11/2 equation (2)
by solving 2 equations
x= -3.875
y= 1.625
∴ x+ y = 1.625 +(-3.875) = -2.25

If f(x)=2(x-3)x4, what is f(-2)? PLEASE HELP ILL GIVE BRAINLIEST
Answer:
f(-2) = -40
Step-by-step explanation:
f(x) = 2(x - 3) • 4
Plug in -2 for x.
f(-2) = 2(-2 - 3) • 4
Follow PEMDAS
f(-2) = 2(-5) • 4
f(-2) = -10 • 4
f(-2) = -40
Answer:
[tex]f(x) = 2(x - 3) \times 4 \\ f(x) = 8(x - 3) \\ f( - 2) = 8( - 2 - 3) \\ f( - 2) = 8 \times ( - 5) \\ \boxed{f( - 2) = - 40}[/tex]

Answer:
7 miles per hour.
Step-by-step explanation:
Right now, the relationship in the problem represents 3[tex]\frac{1}{2}[/tex] miles in hours. To find out what the unit rate is (number of miles per mile), we need to multiply both sides of the equation show BeLoW:
3[tex]\frac{1}{2}[/tex] = [tex]\frac{1}{2}[/tex]
7 miles = 1 hour
Therefore, Doug's average speed in miles per hour is 7 (7 miles per hour).

On Saturdays, Eve earns $14 per hour for yard work and an extra amount for dog walking. Look at the table. Choose the linear function f Eve can use to determine her pay.
Hours 1 2 3 4 5
Pay 26 40 54 68 82
A. f(x) = x + 14
B. f(x) = 12x + 16
C. f(x) = 12x + 14
D. f(x) = 14x + 12
The linear function f Eve can use to determine her pay would be; D. f(x) = 14x + 12
What is a linear equation?A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is the form Ax + B = 0.
Given that Eve earns $14 per hour for yard work and an extra amount for dog walking on Saturdays.
The table shows the data;
Hours 1 2 3 4 5
Pay 26 40 54 68 82
Thus, the linear function f Eve can use to determine her pay is;
f(x) = 14x + 12
To check;
f(x) = 14x + 12
f(x) = 14(1) + 12
f(x) = 14 + 12 = 26
Hence, The linear function f Eve can use to determine her pay would be; D. f(x) = 14x + 12

ABCD is a rhombus.
Find each angle.
Reason:
Plz answer ASAP, thank you
Answer:
Step-by-step explanation:
I sympathize. The question is not very clear: you don't know what A and B really are (I mean which vertex).
However it is a rhombus, and you are to assume that B follows A. So put A anywhere and make B follow it. They are supplementary which means they add to 180 degrees. All rhombi have that property.
A + B = 180
A/B = 2/1
Cross Multiply the second equation
A = 2*B
Put 2B into the first equation.
2B + B = 180 Combine the left terms
3B = 180 Divide both sides of the equation by 3
B = 180 / 3
B = 60
B = 60
A = 180 - 60 = 120
Label the two acute angles as 60 and the two obtuse angles as 120.
Acute: means less than 90
Obtuse: means more than 90
Moises ate 10% of the candies in the bag. If Moises ate 16 candies, how many candies were there total in the bag?
Answer:
160
Step-by-step explanation:
10% of the candies is 16, and to get 100% from 10% is to multiply by 10.
So 10% *10 = 100%, then by association if 16 = 10%, then 16*10 will be the total 100%.

The coordinates of F(x,y) is (5,-4) with midpoint of EF is M(1,-1)
What is midpoint of line segment?
The midpoint divides the line segment into two equal parts. As the number line progresses, the leftmost numbers become smaller, and the rightmost numbers become larger. Adding, subtracting, and multiplying can also be done using a number line like for addition move towards right and for subtraction move towards left.
Here, the mid point of line EF is M with coordinates (1,-1) with coordinates of E(-3,2) therefore, using mid point formula to find coordinates of F(x,y)
[tex]\begin{aligned}\frac{-3+x}{2}&=1\\x&=2+3\\&=5\end{aligned}[/tex]
and for y coordinates of F :
[tex]\begin{aligned}\frac{2+y}{2}&=-1\\y&=-2-2\\&=-4\end{aligned}[/tex]
Therefore, the coordinates of F(x,y) is (5,-4) with midpoint of EF is M(1,-1)

A 13 3/4 -inch candle burns down in 11 hours. If b represents how much of the candle, in inches, has burned away at any time given in hours, t, write a proportional equation for b in terms of t that matches the context.
Answer:
5t = 4b
Step-by-step explanation:
Here, we want to write a proportional relationship for b in terms of t
From the question, b represent the amount of candle burned away in a given time t hours
From what we have initially, 13 3/4 burnt in 11 hours
So in 1 hour, the amount burnt will be;
55/4/11 = 5/4
5/4 inches of candle burnt in 1 hour
5/4 inches = b/t
So b inches burnt in t hours
5/4 = b/t
5t = 4b
