Answer:
top down: 13, 3, -7, -47
Step-by-step explanation:
You evaluate any equation by putting the numbers in place of the corresponding variables and following the rules of arithmetic.
For x = -1, put -1 where x is and do the math.
y = -10(-1) +3 = 10 +3 = 13
For x = 0, put 0 where x is and do the math.
y = -10(0) +3 = 0 +3 = 3
For x = 1, put 1 where x is and do the math.
y = -10(1) +3 = -10 +3 = -7
For x = 5, put 5 where x is and do the math.
y = -10(5) +3 = -50 +3 = -47
The table values are 13, 3, -7, -47.

A square with 20 meters shown as 12 centimeters, how long would a girder appear 15 meters long?
Answers
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

Suppose you deposit $200 in a savings account that earns 4% per year. Find the simple interest earned in 2 years. Then find the total of principal plus interest.
Answers
9514 1404 393
Answer:
interest: $16account total: $216Step-by-step explanation:
The amount of interest is given by the simple interest formula:
I = Prt . . . . where P is the amount earning interest, r is the annual rate, t is the number of years
I = $200·0.04·2 = $16.00
The simple interest earned in 2 years is $16.00.
__
The total of principal and interest is found by adding those values:
$200.00 +16.00 = $216.00
The total amount is $216.00.

q(x)= 1/2x - 3; q(x) =-4. Find the value of x
Answers
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
