Answer:
x = 7
Step-by-step explanation:
Expand 3x+2(x-5)=25 which looks like
3x+2x-10=25
Add similar elements: ( 3x+2x = 5x)
5x-10=25
Add 10 to both sides
5x-10+10 = 25 + 10
Simplfy
5x = 35
Divide both sides by 5
5x ÷ 5 = 35 ÷ 5
Simplfy:
x = 7
have a wonderful day
Answer:
<h2>The answer is option C</h2>
Step-by-step explanation:
To find an equation of a line in point slope form when given the slope and a point we use the formula
where
m is the slope
( x1 , y1) is the point
From the question the point is (1,2) and the slope is 6
The equation of the line in point slope form is

Answer:
Option A
Step-by-step explanation:
Here is how to approach the problem:
We see that all our restrictions for all four answer choices are relatively the same with a couple of changes here and there.
One way to eliminate choices would be to look at which restrictions don't match the graph.
At x<-5, there is a linear function that does have a -2 slope and will intersect the x axis at -7. The line ends with an open circle, so any answer choice with a linear restriction of x less than or equal to -5 is wrong. This cancels out choices C and D.
Now we have two choices left.
For the quadratic in the middle, the vertex is at (-2,6) and the vertex is a maximum, meaning our graph needs to have a negative sign in front of the highest degree term. In our case, none of our quadratics left are in standard form, and instead are in vertex form.
Vertext form is f(x) = a(x-h)^2 + k.
h being the x-coordinate of the vertex and k being the y-coordinate.
We know that the opposite of h will be the actual x-coordinate of the vertex, so if our vertex is -2, we will see x+2 inside the parenthesis. This leaves option A as the only correct choice.
The answer is 7/8 find a common denominator or cross multiply
wait i dont know why it wont let me comment or see comments but wheres the picture?
