-9(x) = -117

Solve for "a number" (x). Isolate it. Note the equal sign. What you do to one side, you do to the other. Divide -9 from both sides.

-9x/-9 = -117/-9

x = -117/-9

x = 13

13 is your answer

hope this helps

Let's have X represent the number we're looking for.
Times means that we are multiplying, so let's make an equation.
-9x=-117
We know by looking at this equation that the number is positive since the number is multiplied by a negative and the answer is negative.
Let's get x by itself by dividing both sides by -9.
-117÷-9=13=x

So, the number is 13.

Greta wants to make 5 pounds of a nut mix using peanuts and cashews. Her budget requires the mixture to cost her $6 per pound. P
Vinil7 [7]

Answer:

3 pounds of peanuts and 2 pounds of cashews

Step-by-step explanation:

Let x be the pounds of peanuts and y be the pounds of cashews

Greta wants to make 5 pounds of a nut mix using peanuts and cashews.

So, x+y=5 ----- A

Cost of 1 pound of peanuts = $4

Cost of x pounds of peanuts = 4x

Cost of 1 pound of cashews = $9

Cost of y pounds of cashews = 9y

Her budget requires the mixture to cost her $6 per pound

So, cost of mixture of x pounds of peanuts and y pounds of cashews is 6(x+y)

So, 4x+9y=6(x+y) --- B

Plot A and B

x+y=5 ---Blue

4x+9x=6(x+y) ---Green

Refer the attached figure

Intersection point = (x,y)=(3,2)

Hence she should use 3 pounds of peanuts and 2 pounds of cashews

Write the equation of the line in fully simplified slope-intercept form.
PtichkaEL [24]

Answer:

Consider points (0, -5) and (-6, -1)

» General equation of a line:

{ \tt{y = mx + c}}

  • m is slope
  • c is y-intercept

<u> </u><u>S</u><u>l</u><u>o</u><u>p</u><u>e</u><u> </u><u>(</u><u>m</u><u>)</u><u>:</u>

{ \tt{m =  \frac{ - 1 - ( - 5)}{ - 6 - 0} }} \\  \\ { \tt{m =  \frac{4}{ - 6} }} \\  \\ { \tt{m =  -  \frac{2}{3} }}

<u> </u><u>y</u><u>-</u><u>i</u><u>n</u><u>t</u><u>e</u><u>r</u><u>c</u><u>e</u><u>p</u><u>t</u><u> </u><u>(</u><u>c</u><u>)</u><u>:</u>

{ \tt{y = mx + c}}

consider point (0, -5)

{ \tt{ - 5 = c}} \\ { \tt{c =  - 5}}

Equation:

{ \boxed{ \tt{y =  -  \frac{2}{3} x - 5}}}
