I’m stuck can some one help me

abruzzese [7]

Answer:

3) Midpoint is (-4,0.5)

Option A is correct.

4) Midpoint is (2.5,0)

Option B is correct.

5) The factors are (x+4)(x-7)

Option C is correct.

6) The factors are (x+4)(x+2)

Option A is correct.

Step-by-step explanation:

Question 3

Find midpoint of the following:

(2,-7), (-10,8)

The formula used to find midpoint is: $Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} )$

We have $x_1=2, y_1=-7, x_2=-10,y_2=8$

Putting values and finding midpoint

$Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} )\\Midpoint=(\frac{2-10}{2},\frac{-7+8}{2} )\\Midpoint=(\frac{-8}{2},\frac{1}{2} )\\Midpoint=(-4,0.5 )$

So, Midpoint is (-4,0.5)

Option A is correct.

Question 4

Find midpoint of the following:

(2,-10), (3,10)

The formula used to find midpoint is: $Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} )$

We have $x_1=2, y_1=-10, x_2=3,y_2=10$

Putting values and finding midpoint

$Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} )\\Midpoint=(\frac{2+3}{2},\frac{-10+10}{2} )\\Midpoint=(\frac{5}{2},\frac{0}{2} )\\Midpoint=(2.5,0 )$

So, Midpoint is (2.5,0)

Option B is correct.

Question 5

Factor each completely

$x^2-3x-28$

We will break the middle term and find factors

$x^2-3x-28\\=x^2-7x+4x-28\\Taking\:common\\=x(x-7)+4(x-7)\\=(x+4)(x-7)$

So, the factors are (x+4)(x-7)

Option C is correct.

Question 6

Factor each completely

$x^2+6x+8$

We will break the middle term and find factors

$x^2+6x+8\\=x^2+4x+2x+8\\=x(x+4)+2(x+4)\\=(x+4)(x+2)$

So, the factors are (x+4)(x+2)

Option A is correct.

A boat goes 3/4 hours with a speed of 8 mph and 1/3 hours with a speed of 12 mph. What distance did the boat cover in all this t

Reika [66]

Answer:

10 miles

Step-by-step explanation:

Given: Boat goes $\frac{3}{4}$ hours with 8 mph (i)

Boat goes $\frac{1}{3}$ hours with 12 mph (ii)

Now, lets find out distance separately to get total distance.

Formula for finding distance is

D= $Speed\times time$

D= $\frac{3}{4} \times 8$ (i)

D= $3\times 2$

∴ D1= 6 miles (i)

D= $\frac{1}{3}\times 12$ (ii)

∴D2= 4 miles (ii)

To find total distance, we will add d1 and d2

Total distance = $d1 + d2$

∴ Total distance = $6 + 4$

= 10 miles is the total distance covered by boat in all this time.

What is an equation in slope-intercept form for the line that passes through the points (1, -3) and (3, 1)?

tensa zangetsu [6.8K]

First we need to find the slope:

Slope formula= $\frac{y2-y1}{x2-x1}$

Plug in your given values from the coordinate
Slope = $\frac{1-(-3)}{3-1}$

When we have 2 "-"'s together they turn into a + sign so we add.
Slope = $\frac{1+3=4}{3-1=2}$
Slope = $\frac{4}{2}$

Simplify (in this case divide) the slope:
Slope = $2$

slope-intercept form is:
y=mx+b
Where m=slope
b=y-intercept

So far we have:
y=2x+b

To find b all we have to do is pick any given coordinate and plug it in:
I chose (3,1)

so we plug that in the equation
1=6+b

Now solve for b:
1=6+b
subtract 6 from both sides
b=-5

Final answer:
y=2x-5 (D)
