Answer:

To solve the question the answer is 35y2 - 5 (i think)

Step-by-step explanation:

Yes and it's actually very simple.

To start off:

Simplify the equation: multiply 7 by the numbers in the parentheses getting: 28y2 - 35 .......full equation: 7y2 + (28y2 - 35)

New equation: 7y2 + (28y2 - 35) now combine like terms this means adding each common variable together. in this case, 7y2 and 28y2 would be added together to simplify the equation. Add them together, the new equation is: 35y2 - 5

Lmk if you have any questions i hope this helps

Answer:

$7y^2+7\left(4y^2-5\right)=35y^2-35$

Step-by-step explanation:

Given the expression

$7y^2+7\left(4y^2-5\right)$

First Apply distributive law to expand 7(4y² - 5) : $a\left(b-c\right)=ab-ac$

$7y^2\:+7\left(4y^2\:-\:5\right)\:=7y^2+7\cdot \:\:\:4y^2-7\cdot \:\:\:5$

simplify

$=7y^2+28y^2-35$

Add like terms: 7y²+ 28y²=35y²

$=35y^2-35$

Therefore,

$7y^2+7\left(4y^2-5\right)=35y^2-35$

Is y=3x+4 parallel or perpendicular

Sauron [17]

Answer: $y=3x+4$ is parallel to $y=3x+7$

Step-by-step explanation:

<h3> The complete exercise is: "Is $y=3x+4$ parallel, perpendicular or neither to $y=3x+7$ ?"</h3><h3 />

The equation of the line in Slope-Intercept form is:

$y=mx+b$

Where "m" is the slope of the line and "b" is the y-intercept.

First, in order to solve this exercise it is important to remember that, by definition:

1. The slopes of parallel lines are equal.

2. The slopes of perpendicular lines are negative reciprocal.

In this case, you have the following line given in the exercise:

$y=3x+4$

You can identify that "m" and "b" are:

$m=3\\b=4$

And the other line provided in the exercise is this one:

$y=3x+7$

So, you can identify that:

$m=3\\b=7$

As you can notice, the slopes of both lines are equal; therefore, you can conclude that those lines are parallel.

Tomtit [17]

After exchanging his Canadian dollar to U.S dollar, Greg only has 4/5 of 200 which is equal to 160 U.S dollars. He had spent 3/4 of the U.S dollars he has, which means that he had spent 3/4 of 160 or equal to 120 U.S dollars. He is then left with only 40 U.S. dollars.
