Answer: to find y, simply make the equation y+82=180 since we know a straight line is 180 degrees. Solving gives us Y=98.
To find Z we can use the vertical angles property. Y is equal to 4z+14 in this property. Since we know y=98, we can say that 4z+14=98. Let’s solve again. We get Z=21.
Step-by-step explanation: AGAIN, please ask me if this doesn’t make sense. I’ll try my best to explain further. Merry christmas lkwkn
Answer:
y = - 4x - 13
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 4, thus
y = - 4x ++ c ← is the partial equation
To find c substitute (- 3, - 1) into the partial equation
- 1 = 12 + c ⇒ c = - 1 - 12 = - 13
y = - 4x - 13 ← equation of line
Answer:
The speed of the car is 250. The error the student made is they didn't look at the hours.
Step-by-step explanation:
If you compare table values to answer choices, you can see right away that several don't work. The number of centimeters is greater than the number of inches, so adding to or multiplying the number of centimeters by some number more than 1 will not give you the smalller number that is inches.
While it may work for the first number (5 inches) to add 7.7 to get the first number of centimeters (12.7), you have to know that you can only add like to like. You can only add inches to inches (getting a result of inches), or centimeters to centimeters (getting a result of centimeters). From the point of view of the units involved, it is <em>nonsensical</em> to add a pure number to a number of inches and expect to get a number of centimeters.
So, we're down to the second choice:
- The number of inches is multiplied by 2.54 to find the number of centimeters.
_____
To find the pattern in the table, you can ...
- observe that the inch values differ by 1
- observe that the centimeter values differ by 2.54
- realize that the constant differences mean the relation between inches and centimeters is linear, and that a change in an inch value of 1 inch is multiplied by 2.54 to find the corresponding change in centimeter value.
_____
I don't know what the first step in your problem solving process is supposed to be. In my problem solving process, the first step is always to <em>look at what you are given</em>. The next step is <em>look at what you are being asked for</em>.
