Answer:

48

Step-by-step explanation:

7x+42=11(3x+8)−2(13x−1)

Step 1: Simplify both sides of the equation.

7x+42=11(3x+8)−2(13x−1)

7x+42=(11)(3x)+(11)(8)+(−2)(13x)+(−2)(−1)(Distribute)

7x+42=33x+88+−26x+2

7x+42=(33x+−26x)+(88+2)(Combine Like Terms)

7x+42=7x+90

7x+42=7x+90

Step 2: Subtract 7x from both sides.

7x+42−7x=7x+90−7x

42=90

Step 3: Subtract 42 from both sides.

42−42=90−42

0=48

Answer: contradiction

Step-by-step explanation:

7v+42=11(3v+8)-2(13v-1)

Open the bracket

7v+42=33v+88-26v+2

7v+42=33v-26v+88+2

7v+42=7v+90

Collect like term

7v-7v=90-42

0=48

This shows that

7v+42=7v+90 contradict

How do you find the vertex if the equation is given ingiven in factored form?
lidiya [134]
If the equation is given in factored form and the roots are real, then you can identify the x-coordinate of the vertex by averaging the 2 root values.  For example, if the roots are -2 and 5, the x-coord. of the vertex is (-2+5)/2, or 3/2.

Once you have this x value, subst. the value into the given equation to calculate y.  Then write the vertex as (x,y).

serg [7]

Answer:

options 3 and 6

Step-by-step explanation:

the exponent x+2 means that the graph moves to the left 2 units and the value of K, which is -4, means that the graph will then move down 4 units from the parent function f(x)
