Answer:

y=3x+7

Step-by-step explanation:

The equation of a line in slope-intercept form is:

y=mx+b

where m is the slope and b is the y-intercept.

We know the slope is 3, so we can substitute 3 in for m.

y=3x+b

We also know the y-intercept is (0,7). When writing the equation of a line in this form, we can ignore the x-coordinate of 0. Therefore, the y-intercept is also just 7. Substitute 7 in for b.

y=3x+7

The equation of a line with a slope of 3 and a y-intercept of (0,7) is y=3x+7

Answer: y = 3x + 7

Step-by-step explanation:

Since we are given the slope and y intercept we could write the equation in slope intercept form as y=mx +b .Only m and b are needed to write the equation.M is the slope and B is the y intercept.

ale4655 [162]

Answer:

332

Step-by-step explanation:

To find how many seats there were, multiply the number of rows with the number of seats in each row:

15 (24) = 360

From these total seats, there are 28 empty seats, meaning:

360 - 28 = 332

There were 332 people.

The inscribed angle theorem says that the measure of angle BDC is 2 times larger than the measure of angle BAC.

Angle CBD has measure 44 degrees, and we're told angles CBD and BCD are congruent. This means triangle BCD is isosceles.

The interior angle measures of any triangle add up to 180 degrees, so the measure of angle BDC must be

$m\angle BDC=180^\circ-2(44^\circ)=92^\circ$

Then $m\angle BAC=\dfrac{92^\circ}2=46^\circ$ .

Simplify (1/3x+3)=5-x<br> The answers 3/4 I just don’t know how to solve it.

omeli [17]

(1/3x+3)=5-x

multiply both sides by three

1x+9=15-3x

add 3x to both sides

4x+9=15

subtract 9 from both sides

4x=3

divide both sides by 4 to isolate x

x=3/4
