Therefore, 0.8 (8/10) is put on the number line shown below.
Answer:
14, -7, -2
Step-by-step explanation:
<u>The coefficient is the number that multiplies the variable, so list the numbers that fall under that definition:</u>
14x - 7x + 1 - 2x
↑ ↑ ↑
14 -7 -2
<u>The coefficients in the expression are </u><u>14, -7, and -2.</u>
Answer:
A. Matrix A
Step-by-step explanation:
When you put a systems of linear equations in matrix form, you take only the coefficients of the <em>xy </em>terms and sort them. <em>x</em> goes first, <em>y</em> comes after, and the numbers after the bars are the constants.
Answer:
x=20
Step-by-step explanation:
Well just cross multiply if its easier
x(3)=3x
12*5=60
60=3x
x=20
Answer:
Step-by-step explanation:
x² - 12x + a = (x + b)²
x² - 12x + a = x² + 2xb + b²
-12 = 2b and a = b²
b = -6
a = b² = 36
