What is the image of (-7,-4) after a dilation by scale factor of 5 centered at the origin

Answer:

y = -1

Step-by-step explanation:

Put the equation in the form y = mx + b where m is the slope and b is the y-intercept.

First, find the slope by doing change in y / change in x:

-1 - (-1) / 8 - 4  = 0 / 4 = 0

this means that m = 0, so the equation so far is y = 0x + b or y = b

Then, you need to find what b is and since you know x = 8 and y = -1 is a solution, you can plug that into the equation:

-1 = 0 * 8 + b

-1 = b

This means that b = -1 and the equation would be y = -1

Answer:

y=-1

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-1-(-1))/(4-8)

m=(-1+1)/-4=0/-4=0

slope is 0

y-y1=m(x-x1)

y-(-1)=0(x-8)

y+1=0

y=0-1=-1

y=-1

Answer:

Multiply the second equation by 2

Solution: [tex](-\frac{45}{11},\frac{29}{11})[/tex]

Step-by-step explanation:

1) In order to use the elimination method to solve systems of equations, you must first multiply one or both of the equations so that the coefficients of a pair of terms with matching variables share the same number, but have opposite signs.

In this case, the y terms must fit that requirement. The y term in the first equation is 2y and the one in the second equation is -y. They already have opposite signs, one positive and other negative, so we just need -y to be -2y. So, in order to do that, multiply by 2.

2) After multiplying the whole second equation by 2, you will get [tex]8x - 2y = -38[/tex]. Now, add the the two equations together, eliminate the y terms, and isolate x to find its value.

3) Then, substitute that x value back into one of the equations to receive the y-value.

Transform System A to system B

option c

Transform System B to system C

option b

2x - 4y = -10          ---------A1

-8x + 7y = 22        ----------A2

A1 * 4   --------> 8x - 16y = - 40

A2        --------> -8x + 7y = 22       {Add }

                         -9y       = -18      -------------B2

B2 ÷ (-9)      y = 2

Step-by-step explanation:

Using Trigonometry,

tan33° = Opposite/Adjacent = GF/DF.

Therefore GF = DF * tan33°

= 235tan33° = 152.6.

Angle GEF = Angle EDG + Angle DGE

= 33° + 34° = 67°. (Exterior Angle Theorem)

Using Trigonometry,

sin67° = Opposite/Hypotenuse = GF/EF.

Therefore EF = GF / sin67°

= 152.6 / sin67° = 165.8.

Hence the answer is the 1st option.

Answer:

the answer is A. GF =152.6 and EG=165.8

GF= 235*(tan(33))

EG= 152.6/(sin(67))

Answer:

There will be 180 mp3s defective

Step-by-step explanation:

Since out of 50, there are 4 defective, so you have to do 2,250 divided by 50, which is 45. Then multiply 45 by 4 to get 180

Answer:

3x+4y= 12.5-----------1

3x+2y= 8.5------------2

Step-by-step explanation:

Given data

let cheese pizza be x and  mushroom pizza be y

Hence

3x+4y= 12.5-----------------------1

also

3x+2y= 8.5--------------------------2

Hence the systems of the equation is given as

3x+4y= 12.5-----------1

3x+2y= 8.5------------2

Given:

The graph of a line.

To find:

The y-intercept of the line.

Solution:

y-intercept is the point where the graph intersect the y-axis.

From the given graph it is clear that the line intersect the y-axis at point (0,3).

So, the y-intercept of the given line is 3.

y-intercept = 3

Therefore, the correct option is C.

Answer:

2. I assume you're working on 1 so I skipped it. 2 would be 16000 yearly. 300 a week would equal 15,000 a year so its less

There are 52 weeks in a year which is how I got that number^

3. With the job he has he gets 21,548.8 per year(11.20 × 37 = 414.4 x 52 = 21,548.8). With the advertised job he would would get 21,150 yearly. 21000 + 5% of 3000 which would be his commission. so stick with his current job

4. (£9.40 x 35 hours = £329) (£329 x 52 weeks = £17,108). (3 extra hours per week x 52 weeks = £156) (£17,108 + £156 = £17,264) That is her total

Answer:

This is by far the easiest question ever...Can you actually read and put effort into it before looking up all your answers next time? It literally says there are 16 CATS and 14 DOGS in a SHELTER. Its not A, because it did not mention rabbits. Its not C because it did not mention too much about cats, and it said dogs and cats not cats and cats. And its not D because we aint talking about a neighborhood. So..it is B. Easy, peasy, lemon squeezy!

Answer:

+ 38,000

Step-by-step explanation:

Given that:

Altitude of airplane = 38,000

The altitude of an object such as airplane in this scenario refers to the height of the airplane above sea level. The sea level is represented as a zero point (mid level) such that distance below are negative and those above are positive.

Hence, at an altitude of 38000 feets, altitude of airplane can be represented as +38,000 feets.
