Which ordered pair is a solution of the equation y=4x+9

Mathematics

Bess [88]4 years ago
7 0

Answer:

There are many answers, but one example would be (1, 13)

Step-by-step explanation:

In order to find this, we simply need to select an x and it will help us find y. Our x for this case will be 1. Now we put that into the equation and solve for the y value.

y = 4x + 9

y = 4(1) + 9

y = 4 + 9

y = 13

This gives us the ordered pair of (1, 13)

A school’s yearbook committee had many meetings last month the line plot summarizes how long each meeting lasted
kipiarov [429]

On the graph, it shows that the shortest meeting has lasted for 1/4 of an hour. An hour has 60 mins, you know it the shortest will be 15 minutes.

If its for any other number that you do not know, you can list as a proportion:

1/4 = x/60 (1 and x are on the top of the fractions)

Cross multiply: 1 * 60 = 60

Then divide by the number on the opposite corner of x: 60/4

x = 15

Arisa [49]

Answer: 56.64%

Step-by-step explanation:

Given: Previous amount of flour = 2.26 kilograms

By the end of the baking session, amount of flour = 0.98 kilograms

Decrease in amount = 2.26-0.98 = 1.28  kilograms

Percent decrese = \dfrac{\text{decrease in amount }}{\text{previous amount}}\times100

=\dfrac{1.28}{2.26}\times100\approx56.64\%

Hence, the percent decrease in the amount of flour = 56.64%

15 POINTS PLEASEE SOMEOKE HELP ME WITH THIS
attashe74 [19]
Imagine each horizontal line as 180 degrees. So if your angle measure on the top right is 81 the other side of that will be 99 degrees and then you can apply vertical angles. Since angle two is a vertical angle to the degree measure of 81 it is also 81. Which means angle three is equal to angle 1, which is 99 degrees. Now since the horizontal lines are parallel the same angle measure will apply to angles 4,5,6, and 7

Final answer angles 1,3,4,7 are 99 degrees
And angles 2,5,6 are 81 degrees
