Y=1/2 (8-x)+3 if you're doing y=mx+b

(1/2)x - 1 should be the answer
Distribute 1/2 to x and 8 which gives you (1/2)x and - 4
(1/2)x - 4 = Y - 3
Bring - 3 to the other side
(1/2)x - 4 +3
(1/2)x - 1 = Y

Solve the system of equations by graphing. Look at the picture. Will Mark Brainliest

aleksandr82 [10.1K]

Answer:

See below

Step-by-step explanation:

<h3>Graphing:</h3>

we are given two functions

$\displaystyle \begin{cases}f(x) = - x + 5 \\ g(x) = {x}^{2} - 3x + 2\end{cases}$

where f(x) is a linear function and g(x) is a quadratic function

we want to figure out the solutions of the function

let's graph f(x):

the Black-table is attached

let's graph g(x):

the picture is attached

hence, the graph should be

the graph is attached

<h3>solutions stating:</h3>

so we need solution(s) which satisfy(ies) the both functions

in this case the solution (s) the x coordinate(s) where both functions intercept we get from the graph that both functions intercept at (-1,6) and (3,2)

hence,

x={-1,3}

Over the x-axis: (x, y)  (x, –y)
Over the y-axis: (x, y)  (–x, y)
Over the line y = x: (x, y)  (y, x)
Through the origin: (x, y)  (–x, –y)

Paolo is using his grandmother's breakfast bar recipe. He always doubles

Papessa [141]

Answer:

$6\frac{1}{3}$ = $2\frac{1}{2}$ * 2 + $\frac{x}{2}$

Step-by-step explanation:

lets start with what we know.

the recipe calls for 2 $\frac{1}{2}$ cups of yogurt. and Paolo doubles the recipe. so multiply the recipe for yogurt by 2

2 $\frac{1}{2}$ * 2 = 5 cups of yogurt.

the total of yogurt and oats is $6\frac{1}{3}$ and we know how much yogurt we have so we subtract that from the total of both.

$6\frac{1}{3}$ - 5 = $1\frac{1}{3}$

the oats after doubling were $1\frac{1}{3}$ cups so u divide it by 2

$1\frac{1}{3}$ / 2 = $\frac{2}{3}$ before doubling

AXY Zand AABCare similar triangles. Given the dimensions shown in the diagram, what is the

Lady bird [3.3K]

Answer:

3.528

Step-by-step explanation:

First, you need to determine the scale factor. Divide one side in the larger triangle by the corresponding side in the smaller triangle. For example, 8/2. This would give you a scale factor of 2. Then you can reverse the process with the dimensions you need to get the area. The height of the larger triangle is 3.36, so to find the height of the smaller one, you divide it by 2, or the scale factor, to get the height of the smaller triangle which is 1.68. Next, you can solve for area of triangle using a=bh/2, so 4.2*1.68/2=a = 3.528.
