Solving linear systems of substitution

Mathematics
1 answer:
never [62]3 years ago
6 0
Example: 2x+2y=8 and 3y+2x=6
Okay so u first want to put on of the equations into a y= form. So let's use 3y+2x=6. Subtract 2x from both sides. 3y=6-2x divide by 3. Y= 6-2/3x or y= -2/3x + 6. Now just plug this new equation in for Y since "y=" into the other equation.
2x + 2(-2/3x + 6) = 8.
Then you would distribute the 2 into the parenthesis and simplify to solve for x.
After you solve for x, plug x into one of the original equations to find y.

How many books were read in all? <br>A. 150 <br>B.156 <br>C. 158 <br>D. 160 <br>E. 162​
Anarel [89]

Answer:

D: 160

Step-by-step explanation:

Fifth graders read 68, which is easy to see.  Fourth graders read between 48 and 52, the bar appears to be directly in the middle of the two lines, so we say they read 50.  Third graders read between 40 and 44, again the bar appears to be directly in the middle so we say they read 42.

42+50+68=160

write an equation in point-slope form and slope-intercept form for a line that passes through point(4,-1) and has a slope of -3
melamori03 [73]

Answer:

Point Slope: (y-(-1)=3(x-4)

Step-by-step explanation:

y-y1=m(x-x1) Point Slope Form\\plug in:\\y-(-1)=3(x-4)\\

Slope Intercept is y=mx+b\\Find Y Int (b):\\b=-13\\Plug in;\\y=3x-13

The function f(x) = x2 is translated 7 units to the left and 3 units down to form the function g(x). Which represents g(x)?
nignag [31]

Answer:

B. g(x)=(x+7)^2-3

Step-by-step explanation:

Vertex form is F(x)= a(x-h)^2+k

a is the reflection

h and k are the vertex (x,y) = (h,k)

in this case there is no shrink or stretch (a)

if it is translating left or right it is "h". In this case it is translated left so its -7.  However if you look at vertex form it is "x-h" so -7-7= +7

If it translating up or down it is "K".  In this case it is translated down so its -3.  

If it was translated up or right then its positive.  If it was translated down or left its negative.

After you figure out what h and k are then you just plug it in.  h=-7, k=-3

so the answer in vertex form is, g(x)=(x+7)^2-3
