<h3>x intercept is -3 and y intercept is 9</h3>
<em><u>Solution:</u></em>
<em><u>Given equation of line is:</u></em>
y = 3x + 9
<u>Find the x intercept:</u>
Substitute y = 0 in given
0 = 3x + 9
3x = -9
Divide both sides by 3
x = -3
Thus x intercept is -3
<u>Find the y intercept:</u>
Substitute x = 0 in given
y = 3(0) + 9
y = 0 + 9
y = 9
Thus the y intercept is 9
Answer:
3.2 × 10^4
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10
. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
3.2 × 10
^4
Answer:
-6u + 7
Step-by-Step Explanation:
Rearrange Terms:
(8 - u) - 1(5u + 1)
(-u + 8) - 1(5u + 1)
Distribute:
(-u + 8) - 1(5u + 1)
(-u + 8) - 5u - 1
Eliminate Redundant Parentheses:
(-u + 8) - 5u - 1
-u + 8 - 5u - 1
Subtract the Numbers:
-u + 8 - 5u - 1
-u + 7 - 5u
Combine Like Terms
-u + 7 - 5u
-6u + 7
Solution:
-6u + 7
Answer:
the height is 14
Step-by-step explanation:
since the volume in a rect. prism is V = width x height x length, and the width times length is the area of the base, for height we need to do 840/60 to find the height
840/60 = 14
Answer:
The system of equations is the option A
Step-by-step explanation:
Let
x ------> the number of tickets for the roller-coaster
y ------> the number of tickets for the bumper
z ------> the number of tickets for the Ferris wheel
we know that
The system of equations is equal to
<em>John</em>
2x+3y+z=42
<em>Darren</em>
3x+y+2z=36
<em>Shelley</em>
x+2y+3z=32
therefore
The system of equations is the option A
