-2 (5x-4)= 8-3x solve for x
Answer:
x=0
Step-by-step explanation:
-2*(5x-4)=8-3x
-2x * 5x -2 * -4= 8 -3x
-10x+8=8-3x
-10x+3x+8=8-3x+3x
-10x+3x+8=8-3x+3x
-7x+8=8-3x+3x+8
-7x+8=8
-7x=8-8
-7x=0
x=0
Answer:
x = 0
Step-by-step explanation:
First, distribute
- 2 (5x - 4) = 8 - 3x
-10x + 8 = 8 - 3x
Next, rearrange the terms
-10x + 8 = 8 - 3x
-10x + 8 = -3x + 8
Then, Subtract 8 from both sides of the equation
-10x + 8 = -3x + 8
-10x + 8 - 8 = -3x + 8 -8
Then, simplify (I'm not gonna show how but if you want me to just let me know)
-10x = -3x
Then, add 3x to both sides of the equation
-10x = -3x
-10x + -3x = -3x + 3x
Then, simplify
-7x = 0
Then, divide both sides of the equation by the same term
-7x = 0
-7x/-7 = 0/-7
Finally, simplify
x = 0/-7
and you'll get
x = 0
Leo sold candy bars for a fundraiser. He spent $25 on a box of candy bars and sold them for $2 each. His profit (after earning back the $25) was $69, so he used the equation $2c−$25=$69 to find out how many candy bars he sold.
Solve for c.
Answer:
Step-by-step explanation:
2c - 25 = 69
2c - 25 + 25 = 69 + 25
2c = 94
2c/2 = 94/2
c = 47 bars
Answer:
c=47

Abc is a right-angled triangle d lies on bc, and dc=db Bc=14 cm
Answer: 19.78
Step-by-step explanation:
Are you trying to use the Pythagorean theorem? If so, here.
Since the two legs are the same, you use one multiplication equation.
14 x 14=196
196+196= 392
Square root 392: Aproximately 19.78
cathleen planned to walk her dog for 3/4 f a mile after it started to rain she decided to only walk 1/2 of that distance what fraction of a mile did cathleen walk her dog
Answer:
Cathleen walked 3/8 mile.
Step-by-step explanation:
Since we are trying to find 1/2 of 3/4, we'll start by converting 3/4 into a form where we can find 1/2, becuase 1.5/4 is not a valid answer.
The simplest form other than 3/4 would be 6/8, we'll get that by multiplying 3 by 2 and 4 by 2. We just need to find half of 6, which is 3. Therefore, Cathleen walked 3/8 mile.

Step-by-step explanation:
how do you convert y=-2x²+4x-1 into vertex form
Answer:
y = –2(x – 1)² + 1
Step-by-step explanation:
Given the quadratic function, y = -2x²+ 4x - 1:
where a = -2, b = 4, and c = -1
The vertex of a parabola is the point on the graph where the parabola intersects the axis of symmetry. The axis of symmetry occurs at x = h. Therefore, the x-coordinate of the vertex is the same as h.
To find the vertex, (h, k), you need to solve for h by using the formula:
Plug in the values into the formula:
[tex]h = \frac{-b}{2a}[/tex]
[tex]h = \frac{-4}{2(-2)} = 1[/tex]
Therefore, h = 1.
Next, to find the k, plug in the value of h into the original equation:
k = -2x²+ 4x - 1
k = -2(1)²+ 4(1) - 1
k = 1
Therefore, the value of k = 1.
The vertex (h, k ) occurs at point (1, 1).
Now that you have the value for the vertex, you can plug these values into the vertex form:
y = a(x - h)² + k
a = determines whether the graph opens up or down; it also makes the parent function wider or narrower.
If a is positive, the graph opens up. If a is negative, the graph opens down.h = determines how far left or right the parent function is translated.
k = determines how far up or down the parent function is translated.
Plug in the vertex, (1, 1) into the vertex form:
y = –2(x – 1)² + 1
This parabola is downward facing, with its vertex, (1, 1) as its maximum point on the graph.
