Answer:

x = 7

Step-by-step explanation:

Given

<em>2</em><em>(</em><em>2</em><em>x</em><em> </em><em>+</em><em> </em><em>1</em><em>)</em><em> </em><em>=</em><em> </em><em>3</em><em>0</em>

<em>4x </em><em>+</em><em> </em><em>2</em><em> </em><em>=</em><em> </em><em>3</em><em>0</em>

<em>4x </em><em>=</em><em> </em><em>3</em><em>0</em><em> </em><em>-</em><em> </em><em>2</em>

<em>4x </em><em>=</em><em> </em><em>2</em><em>8</em>

<em>x </em><em>=</em><em> </em><em>2</em><em>8</em><em>/</em><em> </em><em>4</em>

<em>x </em><em>=</em><em> </em><em>7</em>

<em>Hope </em><em>it </em><em>helps </em><em>:</em><em>)</em><em>❤</em>

Y=-10x+50 <br><br> x=9, <br><br><br> y=??
Fittoniya [83]

Answer:

-40

Step-by-step explanation:

Plug in 9 for x.

Use Order of operations

-10(9) = -90

-90 + 50 is the same thing as saying 50 - 90

we can simplify by splitting the -90 in to a -40 and a -50

the new equation could be 50 - 50 -40.

50 - 50 = 0

0-40 = -40

I didn’t find equation in point slope form for the line parallel To y=1/2x-7 that passes through (-3,-2)
amid [387]

Answer:

y +2 = (1/2)(x +3)

Step-by-step explanation:

It is helpful to know that the point-slope form of the equation with slope m through point (h, k) is ...

... y -k = m(x -h)

You have a line with a slope of 1/2. The parallel line will also have a slope of 1/2, so m = 1/2. The point you want on your line is (-3, -2), so (h, k) = (-3, -2). Putting these values into the point-slope form gives you ...

... y -(-2) = (1/2)(x -(-3))

Simplifying this gives ...

... y +2 = (1/2)(x +3)

I have to determine the coordinates of the x-intercepts of the parabola. please help I need assistance with this practice proble
Roman55 [17]

The x-intercept of a graph refers to the points where the graph cuts or intersects the x-axis.

These are the x-values when y is equal to zero.

From the graph provided, the values of x when the graph cuts the x-axis are:

\begin{gathered} x=-3 \\ and \\ x=-1 \end{gathered}

Therefore, the coordinates of the x-intercepts are:

(-3,0)\text{ and }(-1,0)

The answer type is "Two points".

alice planted 6 tomato plants 4 bean plants and 2 pepper plant. each row had 6 plants. how many rows did she plant
ANTONII [103]
First, add the number of plants.

6+4+2= 12 plants in total

There can be 6 plants in each row so divide 12 by 6 to get the number of rows used to plant 12 plants.

12/6=2

The answer is 2 rows.
