on a piece of paper, graph y<-3/4x+2. Then determine which answer choice matches the graph you drew.

exis [7]

Answer:

D. Graph D

Step-by-step explanation:

The "y <" tells you two things: (1) shading will be below the line, where y-values are less than those on the line, and (2) the line will be dashed, because the "equal to" case is not included.

Only one graph has a dashed line with shading below: Graph D.

Determine if the equations are parallel, perpendicular, or neither.

Aloiza [94]

To easily find the slope from standard form (Ax + By = C) use -A/B

1. m = -5/3
2. m = -3/5

perpendicular slopes are negative reciprocals, which these are not

parallel slopes are exactly the same, which these are also not

so, these equations are neither parallel nor perpendicular

Justin walk 5 kilometer and he turn right and he swim 35 meters why the apple is red?

Morgarella [4.7K]

Answer:

Red apples get their color from anthocyanins. These are pigments, or natural colorings, that develop as the apple grows. It absorbs all the colors of the rainbow—except for red. The red light reflects off the apple and our brain and eyes work together to let us know what color we are seeing

Step-by-step explanation:

The first part of the question does not correlate to the final question the problem is asking. Therefore, we just need to find out why apples are red. A simple google search can tell you why ^^

To wash a window that is 7 meters off the ground, Roger leans a 9-meter ladder against the side of the building. To reach the wi

iren2701 [21]

Answer:

Roger should place the base of ladder approximately 5.7 m away from base of building to reach the window.

Step-by-step explanation:

Given,

Length of ladder = 9 m

We have to find that how far Roger should place the base of ladder to reach the window.

Solution,

We have drawn the diagram for your reference.

Here the building, the ladder on leaning with land makes a right angle triangle.

Where the length of ladder is 'hypotenuse'.

Height of window from the ground is 'one side of the triangle'.

And distance from base of building to the ladder is 'another side of the triangle'.

So, according to Pythagoras theorem;

"In a right angled triangle the square of the hypotenuse is equal to the sum of the squares of other two sides".

On framing in equation form, we get;

$c^2=a^2+b^2$

Where 'a' = 1st side of right triangle =7 m

'b' = 2nd side of right triangle

'c' = hypotenuse = 9 m

Now we put the given values and get;

$9^2=7^2+b^2\\\\81=49+b^2\\\\b^2=81-49=32\\\\b^2=32$

Now taking square root on both side, we get;

$\sqrt{b^2} =\sqrt32\\\\b=5.65\ m\approx5.7\ m$

Hence Roger should place the base of ladder approximately 5.7 m away from base of building to reach the window.
