Tell whether (2, 5) is a solution of the equation y = 2x + 1. Show your work. I’LL PUT YOU AS BRAINLIEST

Answers

Answer 1

Answer:

The solution of (2,5) indeed equals the solution of the equation y=2x+1

Step-by-step explanation:

to solve just plug in the values.

y=2(2)+1 which gives us the y value of y=5

to solve for x, plug in y. 5=2x+1.

subtract 1 from both sides, and you get 4=2x

then divide 2 on both sides to get x, which is 2. therefore this is true.

what is the slope-intercept form of the equation of the line that contains the points (1,4) and (0,1)

Answers

Answer:

y = 3x + 1

Step-by-step explanation:

m = ( 1 - 4 ) / ( 0 - 1 ) = 3

( 0 , 1 )

y - 1 = 3(x - 0)

y - 1 = 3x

y = 3x + 1

Answer:

y=3x+1

Step-by-step explanation:

Slope is (y2-y1)/(x2-x1)

therefore slope =

(1-4)/(0-1)

-3/-1

m=3

therefore the equation is

y-y1=m(x-x1)

y-4=3(x-1)

y-4=3x-3

y=3x+1

Adam drove 918 miles on 27 gallons of fuel. at this rate, how many gallons of fuel would it take to drive 510 miles.

Answers

Answer: 15 gallons

Step-by-step explanation:

Here you are going to want to set up a proportion. 918 miles per 27 gallons = 510 miles per x gallons

918/27 = 510/x

Cross multiply and you get 918x = 13770

and you get x = 15

Or you could do 918 miles / 27 gallons = 34 miles / gallon

and divide the 510 miles of distance by how many miles per gallon, so

510 / 34

Answer:

Pizza = x

Ham = 5x

x + 5x = 30

6x = 30

65º
85º
115º

Answers

Answer:

Step-by-step explanation:

It’s 65 because 65+35=100 then u add 80 to get 180

The measure of the third angle in the triangle is 65°. The correct option is B.

What is geometry?

One of the earliest areas of mathematics is geometry, along with arithmetic. It is concerned with spatial characteristics like the separation, shape, size, and relative placement of objects.

Given that Triangle P Q R. Angle Q is 80 degrees and angle P is 35 degrees. Triangle W X Y. Angle W is 35 degrees and angle X is 80 degrees.

The third angle will be calculated as:-

Angle = 180 - 80 - 35

Angle = 65

Therefore, the measure of the third angle in the triangle is 65°. The correct option is B.

Calvin kicked a soccer ball laying on the ground. It was in the air for 5 seconds before it hit the ground. While the soccer ball was in the air it reached a height of approximately 25 feet. Assuming that the soccer ball’s height (in feet) is a function of time (in seconds), what is the range in the context of this problem?

Answers

Answer:

The range is 0-25 feet

Step-by-step explanation:

Mathematically, when we are talking of the range, we are simply referring to the values at the boundaries.

This refers to the y-axis values. That is the values of the dependent variable

If we are to plot the graph, we will have the time on the x-axis while the amount of time spent in air would be on the y-axis

The base height is from the ground which is marked 0 feet to a maximum height of 25 feet

So the range in the context of this problem is 0-25 feet
