Answer:

  (x, y) = (2, 2)

Step-by-step explanation:

The graph is attached.

Both equations are in slope-intercept form:

  y = mx +b . . . . . . line with slope m and y-intercept b

The graph of the first equation intersects the y-axis at +3, and has a slope (rise/run) of -1/2. That is, it decreases 1 unit for each 2 units to the right.

The graph of the second equation intersects the y-axis at -4, and has a slope of +3. It will increase 3 units for each unit to the right.

The point of intersection of the graphed lines is (2, 2).

The solution is (x, y) = (2, 2).

Answer:

-9 + 2y^2 + 7y

Answer:

equation of the line:  y = 3x -4

Step-by-step explanation:

y = 3x - 6

the formula of equation: y = mx + b ......where m is slope and b is y intercept

Here the slope is 3.

......................................................................................................identification done

then given it is parallel so we know:

.........................................................................................................slope type found

then given passes coordinate (3,5)

so using the equation: y - y1 = m ( x - x1 )

                                    : y - 5 = 3 ( x - 3 )

                                    : y - 5 = 3x - 9

                                    : y = 3x - 9 + 5

                                    : y = 3x -4

Answer:

Step-by-step explanation:

We know that:

Let's create a graph. In the graph, let's label the point given and the parallel line. Now, we know that the slope must be the same because if two lines are parallel on a graph, they will have same slopes. Their y-intercepts will be different. Now, I have used the trial-and-error method, to see which y-intercept does the line intersects the point. I found out that the y-intercept is -4 according to the graph.

Hence, the equation of the original line is y = 3x - 4.

Answer:

Step-by-step explanation:

put x=1 ,y=5

y≥4x

5≥(4×1)

5≥4

which is true.

again 5≤1+2

5≤3

which is not true.

so, no (1,5) is not a solution.

To be a solution it should be true for both.

Answer:

x = 850 and y = 345

Step-by-step explanation:

x + y = 1195

x - y = 505

Add the two equations

2x + 0y = 1700

2x = 1700

x = 850

Sub x = 850 into the first equation:

850 + y = 1195

y = 345

Thus, x = 850 and y = 345

Answer:6

Step-by-step explanation: 22 / 4 = 5.5, you need  a whole number so it's 6, we need a whole number because we can't order half a pizza; if we rounded down there wouldn't be enough pizza

Answer:

6 pizzas

Step-by-step explanation:

22 People divided by 4 servings equals 5.5

22/4=5.5 round up to 6 pizzas

Answer:

3/5

Step-by-step explanation:

The slope would be 3/5.

We can get the equation down to y=mx+b form first.

3x - 5y = 7

(Subtract 3x from both sides.)

-5y=-3x+7.

(Divide -5 on both sides.)
y=3/5-7/5.

Now, it is not parallel yet since to be parallel it needs a different y intercept, so just make one up.

Like:

y=3/5-7/3.

To see this visibly to make sure we can use desmos. com.

It is a graphing calculator where you can type the equation to see how it is graphed.

Answer:

m=3/5

Step-by-step explanation:

First rewrite the equation in slope intercept form. y=mx+b

[tex]y=\frac{-3}{-5} x-\frac{7}{5}[/tex]

The -3/-5 becomes positive.

[tex]y=\frac{3}{5} x-\frac{7}{5}[/tex]

In order to be parallel, use a different y value for "b."

Therefore, the slope is 3/5. Hope this helps and have a great day.

The number of peaches in the basket are 8.

An equation is a mathematical statement that shows that two mathematical expressions are equal.

Given that, Sheryl has a basket of ripe apples and peaches. The number of apples in the basket is 12 more than twice the number of peaches, there are 36 apples in the basket, there are peaches in the basket.

Let the number of apples be a and peaches be b,

Establishing the equations,

a-2p = 12

a = 12+2p.....(i)

a+p = 36.....(ii)

Using the equation (i) in equation (ii)

12+2p+p = 36

12+3p = 36

3p = 24

p = 8

Hence, the number of the peaches are 8.

Step-by-step explanation:

m1 = 180-140 = 40

m2 = m1 = 40

m5 = 35

m6 = m5 = 35
