Answer:

Step-by-step explanation:

The given equation is in slope-intercept form:

y = mx + b

where the slope is m = -3 and the y-intercept is b = +2.

So, the graph will have a slope of ...

"rise"/"run" = -3 = -3/1

and will cross the y-axis at y=2.

Graphs A and B cross the y-axis in the right place, but only Graph B has a negative "rise" a x increases.

HELPPPP PLEASEE. IT IS DUE IN 20 MIN. THANK YOU SO MUCH! :)

12345 [234]

Answer:

A.) 65x + 35X + 50 = 250

65x = cost of concrete per cubic yard, x is yd³

35X = cost of pouring/finishing concrete per cubic yard, X is yd³

50 = delivery cost

250 = the money you have

B.) 400 + 15n = 505

15n = amount of money you deposite per week, n is # of week

400 = some money in account after n week passed

505 = initial money in bank

C.) 1.1X - 10 = 55

55 = total cost of clothes

1.1X = tax rate where X is the undiscounted clothe cost

10 = discount

Resolva a equação literal 2x+2a=20, de incógnita

Anton [14]

$2x+2a=20 \ \textgreater \ \mathrm{Subtract\:}2a\mathrm{\:from\:both\:sides} \ \textgreater \ 2x+2a-2a=20-2a$

$\mathrm{Simplify} \ \textgreater \ 2x=20-2a \ \textgreater \ \mathrm{Divide\:both\:sides\:by\:}2 \ \textgreater \ \frac{2x}{2}=\frac{20}{2}-\frac{2a}{2}$

$\frac{2x}{2} \ \textgreater \ \mathrm{Divide\:the\:numbers:}\:\frac{2}{2}=1 \ \textgreater \ x$

$\frac{20}{2}-\frac{2a}{2} \ \textgreater \ \mathrm{Apply\:rule}\:\frac{a}{c}\pm \frac{b}{c}=\frac{a\pm \:b}{c} \ \textgreater \ \frac{20-2a}{2}$

$20-2a \ \textgreater \ \mathrm{Rewrite\:as} \ \textgreater \ 2\cdot \:10-2a \ \textgreater \ \mathrm{Factor\:out\:common\:term\:}2$

$2\left(-a+10\right) \ \textgreater \ \frac{2\left(-a+10\right)}{2} \ \textgreater \ \mathrm{Divide\:the\:numbers:}\:\frac{2}{2}=1 \ \textgreater \ x = -a+10$

Hope this helps!
