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.

Answer:

x = 24

obtuse isosceles triangle

Step-by-step explanation:

x = 24 because a triangle has to have all the angles add up to 180. So x + x +132 = 180.

180-132 = 2x

48 = 2x

x = 24

It is an isosceles because two of the angles are the same and one is different which means two of the sides are the same and one is different. (isosceles = icicle is how I remember it). Obtuse because there is an angle that is over 90 degrees.

A business analyst makes $20 an hour for the first 42 hours he works during a week and $28 an hour for each hour worked over 42

Natasha_Volkova [10]

The piecewise function for this should be $f(x) \left \{ {{y = 20x, x < 42} \atop {y = 28x + 840, x > 42}} \right.$ .

We can find the first equation simply. He gets 20 every hour up to 42 hours. Therefore, the function gives us our first equation of y = 20x when x < 42.

The second one, we must know what the base amount he would make before starting to make 28 an hour. The 28 an hour would be 28x, but he would have already made 840 before hand. Which we can determine by multiplying the base of 42 hrs by 20.

42 * 20 = 840.
