Answer:

y=6x+4

Step-by-step explanation:

now the formula for slope-intercept is y=mx+b

Slope (aka m) is 6

[how I got the slope is every time it goes forward 1 it goes up 6 rise/run]

so y=6x+[y intercept]

the y intercept is 4 as seen in the chart so:

y=6x+4

enjoy^^

Find the slope of the line that passes through the points E(-1, 3) and F(-2, -3)

Nesterboy [21]

Answer=6

Formula for slope:

$slope= \frac{y _{2}-y _{1} }{x _{2}-x _{1} }= \frac{-3-3}{-2-(-1)} = \frac{-6}{-1}=6$

slope=6

Mai says that the equation 2x+2=x+1 has no solutions because the left side is double the right side. Do you agree with mai provi

attashe74 [19]

Answer: No, Mai needs to solve the problem.

Step-by-step explanation:

2x+2=x+1 - subtract 2 from both sides

2x=x-1 - subtract x from both sides

x= -1 - solution

Which equation matches the graph shown?

Kitty [74]

Answer:

f(x) = -(x+2)(x-1)

Step-by-step explanation:

We know the zeros are at 1 and -2

f(x) = a *(x-b1)(x-b2) where b1 and b2 are the zeros and a is a constant

f(x) =a(x-1)(x- -2)

f(x) =a(x-1)(x+2)

We know that a must be negative since the parabola opens down so

The only choice is choice D where a = -1

f(x) = -(x+2)(x-1)

T is the midpoint of PQ

PT=TQ

5x+7 = 7x-7

2x= 14

x= 14/2

x= 7

PT = 5(7)+7 = 42

A train leaves boston and travels toward its destination at a speed of 60 mph. One hour later, an express train leaves Boston an

Margarita [4]

Taking into account the supplied speeds, Boston is from the destination to:

240 miles

<h3>Calculation of the distance between Boston and Place of Destination</h3>

To identify the distance between Boston and the destination of the trains, it must be remembered that the <u>speed</u> mentioned for each one is a reference to the distance traveled per hour, therefore, after each hour, each train will travel :

Regular train: 60 miles
Express train: 80 miles

According to the information given, when the express train leaves, the regular train has a 60-mile lead, which is getting shorter hour by hour because the express train travels 20 miles per hour more than the normal train.

Therefore, in <u>three hours</u>, the express train would catch up with the regular train, calculating the distance thanks to the speed formula:

$Speed =\frac{Distance}{Time}$

And clearing the distance:

$Distance=Speed*Time$

$Distance=80\frac{miles}{hour}*3hours$

$Distance=240miles$

Therefore, the destination would be <u>240 miles</u> from Boston, which would take four hours by regular train and three hours by express train.
