No it is not. Substituting for x=1 and y=3 in the equation, you get 5x - 9y is 5 - 27 = -22

MATH.... TRIANGLE JKL HAS VERTICES...
7nadin3 [17]
<h3>Answer: Choice (d)</h3>

Explanation:

To reflect over the y axis, we apply this rule

(x,y) \to (-x,y)

which says to flip the sign of the x term but keep the y coordinate the same.

So that means something like J(-2,5) becomes J ' (2, 5). The other points are handled in the same fashion and that leads us to choice (d). Points on the y axis will stay where they are.

In preperation for an easter egg hunt, 4 blue eggs are filled for every 7 green. How many green eggs will be filled if 100 blue
ivann1987 [24]

Answer:

1. Typed question: 175 green eggs

2. Attached: 22 tables

Step-by-step explanation:

For the question you typed down, it is a ratio and proportion problem. You need to solve for the ratio proportional to the first ratio given.

4 blue eggs are filled for every 7 green. This means that the ratio between blue eggs and green eggs is 4:7.

Now yo need to figure out a ratio proportional to 4:7 if 100 blue eggs were filled. Below is how this is set up:

\dfrac{4\;blue\;eggs}{7\;green\;eggs} = \dfrac{100\;blue\;eggs}{x\;green\;eggs}

Now let's solve for x:

\dfrac{4\;blue\;eggs}{7\;green\;eggs} = \dfrac{100\;blue\;eggs}{x\;green\;eggs}\\\\or\\\\\dfrac{4}{7}=\dfrac{100}{x}\\\\Cross-multiply\\\\4x = (7)(100)\\\\4x = 700\\\\Divide\;both\;sides\;by\;4\\\\\dfrac{4x}{4}=\dfrac{700}{4}\\\\x=175

For your attached problem:

You have a total of 175 people, you need to figure out how many round tables you need if here are 8 chairs for each table You just need to divide the number of people by the number of chairs per table.

175 ÷ 8 = 21.9 tables

Now since you cannot have half a table, you round up to the nearest whole number. (we round up because you need to make sure that all of them are seated)

21.9 ≅ 22 tables.

Write an equation in point-slope form and slope-intercept form for
slava [35]

Answer:

point slope: y-7=2(x-4

slope intercept: y=2x-1

Step-by-step explanation:

point slope form: y-y1=m(x-x1)

(4,7) and m=2

using all the info here is it in point slope form: <u>y-7=2(x-4)</u>

turning the point slope equation into slope intercept...

slope intercept form: y=mx+b

first simplify y-7=2(x-4) into y-7=2x-8

then add 7 to both sides...

which would be <u>y=2x-1 </u>

and thats your answer!!
