Answer:

D

Step-by-step explanation:

1. To find the x intercepts, set y equal to 0 and solve for x

4x - 2y = 2

4x -2(0) = 2

4x - 0 = 2

4x = 2

x = 1/2

2. To find the y intercepts, set x equal to 0 and solve for y

4x - 2y = 2

4(0) - 2y = 2

0 - 2y = 2

-2y = 2

y = -1

Answer:

Option D

Step-by-step explanation:

<u>Convert to slope-intercept form:</u>

4x-2y=2

-2y=2-4x

y=-1+2x

y=2x-1

<u>Find the x-intercept by plugging in y=0:</u>

<u />y=2x-1<u />

<u />0=2x-1<u />

<u />1=2x<u />

<u />\frac{1}{2}=x<u />

<u />x=\frac{1}{2}<u />

Therefore, the x-intercept is (\frac{1}{2},0)

<u />

<u>Find the y-intercept by plugging in x=0:</u>

<u />y=2x-1<u />

<u />y=2(0)-1<u />

<u />y=0-1<u />

<u />y=-1<u />

Therefore, the y-intercept is (0,-1)

So, the correct answer is option D.

The distance between New York City and Boston is 225 miles. The distance between New York City and salt lake is 10 times as far.
yuradex [85]

Answer: 2,250 meters

Step-by-step explanation:

New York City and Boston are 225 miles apart.

New York City and Salt Lak are 10 times the distance of New York and Boston.

This means that New York City and Salt Lake are 10 times 225 miles apart:

= 225 * 10

= 2,250 meters

What is the decimal multiplier to increase by 1.5 pls do the step by step explanation ineed help
satela [25.4K]

Answer:

Just an explanation so you can understand

Step-by-step explanation:

To increase, or decrease a number N, by a percentage X% we multiply N by a percentage multiplier (often just called multiplier).

We can calculate any percentage increase, or decrease, in three steps:

Step 1: write X% in decimal form. Remember, this is done by moving the number X back two decimal places.

Example: 5%=0.05, 12%=0.12, ... .

Step 2: Calculate the percentage multiplier by adding, or subtracting, the decimal found in step 1 to, or from, 1

For percentage increases: add the decimal to 1.

For percentage decreases: subtract the decimal from 1.

Step 3: multiply the number N by the multiplier, found in Step 2.

List L consists of numbers 1, square root of 2, x, and x^2 , where x&gt;0, and the range of the numbers in list L is 4. Which qu
Hitman42 [59]
If the range of the numbers in the list L is 4, then x can't be 4 since there is an element in the list that is x^2. Therefore,
0 ≤ x^2 ≤ 4 so that it would be the highest number and
0 ≤x ≤ 2

So, the value of x can be equal to 2 but not higher. So, 2 is always greater or equal to x.

abcd is an isosceles trapezoid with legs ab and cd and base bc if the length of ab =-3y+54 the leingth of bc =5y+2 and the leing
Vilka [71]

ANSWER

y = 5

EXPLANATION

The given isosceles tra-pezoid has legs

ab =  - 3y + 54

and

cd = 6y + 9

The base is bc=5y+2.

The length of the legs of the isosceles tra-pezoid are equal.

This implies that,

ab = cd

Thus,

- 3y + 54 = 6y + 9

Group similar terms,

54 - 9 = 6y + 3y

45 = 9y

Divide both sides by 9.

y =  \frac{45}{9}

y = 5

The lesson is 19.2 Angles in inscribed Quadrilaterals
alexdok [17]

Answer:

m<R=44.9,m<S=56.9,m<T=44.9,m<U= 32.9.

Step-by-step explanation:

When two chords are equal then the measure of the arcs are equal.

Chord RU= Chord UT

Or , m arc RU= m arc UT,

3z-4=x+2z+7   Or             z=x+11

Chord RS=Chord ST ,

m arc RS=m arc ST=3x+5

Sum of m arc in a circle =360 degrees.

Or ,

3x+5+3x+5+3z-4+x+2z+7=360

7x+5z+13=360

Substituting z=x+11

7x+5(x+11)+13=360

7x+5x+55+13=360

12x+68=360

12x=292,x=24.3

z=x+11=11+24.3=34.3

m arc RU=marc UT= 3z-4=3(24.3)-4=69

m arc RS =marc ST= 3x+5=3(24..3)+5=77.9

m<R= (marc UT+ m  arc ST)÷2

m<R=(69+77.9)÷2=73.45

m<S= (m arc RU+m arc UT)÷2

m<S= (69+69)÷2=69

m<T=(m arc RU+m arc RS)÷2=73.45

m<U=(m arc RS+m arc m arc ST)÷2=77.9
