Answer:

m=-2

Step-by-step explanation:

7(m+5)=21

m+5=21/7

m+5=3

m=3-5

m=-2

7(m + 5) = 21​

multiply the bracket by 7

(7)(m)=7m

(7)(5)=35

7m+35=21

move +35 to the other side

sign changes from +35 to -35

7m+35-35=21-35

7m=21-35

7m=-14

divide both sides by 7 to get m by itself

7m/7=-14/7

cross out 7 and 7, divide by 7 and then becomes 1*1*m=m

m=-14/7

answer:

m=-2

What are the vertex and x-intercepts of the graph of the function given below?
olchik [2.2K]
The correct question is
<span>What are the vertex and x-intercepts of the graph of the function given below?
y = x</span>²<span>-2x-35

step 1
convert the equation in the vertex form
y+35=x</span>²-2x
y+35=(x²-2x+1-1)
y+35+1=(x²-2x+1)
y+36=(x-1)²------> equation in the vertex form

the vertex is the point (1,-36)

the answer Part a) is
the vertex is the point (1,-36)

Part b) Find the x-intercepts
we know that
the x-intercepts is when y=0
so
y+36=(x-1)²
for y=0
(x-1)²=36
(+/-)(x-1)=√36-------> (+/-)(x-1)=6
(+)(x-1)=6------> x=6+1-----> x=7
(-)(x-1)=6-----> x=1-6-----> x=-5

the x-intercepts are the points
(7,0)  and (-5,0)

the answer part b) is 
the x-intercepts are the points (7,0)  and (-5,0)

the total answer is the option 
<span>A. Vertex: (1, -36); x-intercepts: (7, 0) and (-5, 0)</span>

What is domain and range?
Strike441 [17]
The domain is the complete set of values for which x, or the independent variable, is possible for.

The range is the complete set of values for which y or the dependent variable is possible for.

Hope this helps.
