Answer:Slope is 3 y-intercept is -2

Step-by-step explanation:

y=mx+b. m=slope b is y-intercept

y=3x-2

Comparing both equations we find out that slope is 3 and y-intercept is -2

Answer:

<1=23

Step-by-step explanation:

If WXZ contains both <1 and <2, and <2 is 4 times <1, then we can set this up as x + 4x = 115

This is easily simplified to 5x = 115

Divide both sides by 5 and you will get x=23

Which table will have the greatest value of y when x = 7?

kow [346]

Answer:

(a) (x, y) = (7, 147)

Step-by-step explanation:

Table A represents a quadratic function: y = 3x², so for x=7, y = 3·7² = 147.

Table B represents a linear function: y = 12x +2, so for x=7, y = 86.

Table C represents an exponential function: y = 2^x, so for x=7, y = 128.

Table D represents a linear function: y = 10x +2, so for x=7, y = 72.

The greatest value of y for x=7 will be found in Table A.

_____

Table a's values go down and up, with symmetry about x=0. This suggests a quadratic function. A plain y=x² function will have the value 1 at x=1. This one has the value 3, so looks like y = 3x². Checking values for x=2 and x=3 confirms this.

Table b's values go consistently up, with a difference of 12 each time. The value for x=0 is 2, so we know this linear function has equation y=12x+2.

Table c's values double from one value of x to the next, so the function is exponential with a base of 2. The multiplier is 1, the value for x=0, so the equation is y = 1·2^x.

Table d is similar to table b, except the common difference is 10 instead of 12. So, the slope in slope-intercept form is 10 instead of 12: y = 10x + 2.

Manny makes dinner using 1 box of pasta and 1jar of sauce .If pasta is sold in oackage if 6 boxes and sauce is sold in in packag

EastWind [94]

Answer:

The least number of dinners that manny can make without any supplies leftover is 6 dinners

Step-by-step explanation:

Dinner = 1 box of pasta + 1jar of sauce

pasta is sold in package of 6 boxes

sauce is sold in in packages of 3

jars

what is the least number of dinners that manny can make without any supplies leftover?

Find the lowest common multiple of 6 boxes and 3 jars

6 boxes = 6, 12, 18, 24, 30, 36, 42,48

3 jars = 3, 6, 9, 12, 15, 18, 21, 24, 27, 30

The lowest common multiple of 6 boxes and 3 jars = 6

The least number of dinners that manny can make without any supplies leftover is 6 dinners

Using:

Pasta = 6 dinners / 6 boxes

= 1 package

Pasta = 1 package

Sauce = 6 dinners / 3 jars

= 2 package

Sauce = 2 package
