The product of three is the same as [ * 3 ]

The sum of a number and five is the same as [ n + 5 ]

[ 3 ] is being multiplied to the sum of [ n + 5 ], so, we can write this using the distributive property [ a(b + c) ]

Put the expression together:

3(n + 5)

Best of Luck!

2y+2=4x-6 in slope intercept form

Vesnalui [34]

Answer:

Slope intercept form is y = 2x-4

Step-by-step explanation:

Given equation: 2y + 2 = 4x - 6

The general form of slope intercept form is y = mx+c

2y + 2 = 4x - 6

2y = 4x - 6 -2

2y = 4x -8

dividing throughout by 2

y = 2x -4

Hence the slope intercept form is y = 2x -4

A ball is dropped from the ground. T represents the time in seconds. To find the time you can you the equation Y= -16t^2 +44t. H

bagirrra123 [75]

Answer:

2.75 seconds.

Step-by-step explanation:

We have been given that a ball is dropped from the ground. T represents the time in seconds.

To find the time when the ball was in air, we will equate height of ball with 0 and solve for t.

$-16t^2+44t=0$

Upon dividing both sides by 4, we will get:

$-4t^2+11t=0$

$-t(4t-11)=0$

$-t=0\text{ (or) }(4t-11)=0$

$t=0\text{ (or) }4t-11=0$

$t=0\text{ (or) }4t=11$

$t=0\text{ (or) }t=\frac{11}{4}$

$t=0\text{ (or) }t=2.75$

Since our given function is a downward opening parabola, so ball will be in air between both t-intercepts.

Since the ball touches the ground at 2.75 seconds, therefore, the ball would be in air for approximately 2.75 seconds.

Solve for both x and y value for each angle please

olga_2 [115]

X = 25, y = 14.

This is possible to solve because the vertical angles (7y and 5y + 28 ; 3x +7 and 4x - 18) are equal to each other. To solve for x, just set the two x equations equal to each other. The same is done for y with the y equations.
