Answer:
base = 15 units
Step-by-step explanation:
We are given area of a triangle = 52.5 sq. units
Height is given as 7 and we have to find the base.
Using formula for area of triangle:
Area of triangle = 


52.5 * 2 = base × 7
105 = base × 7
base = 15
55+(x+25)=180
55+x+25=180
25+55+x=180
80+x=180
x=180-80
x=100

<em><u>Solution:</u></em>
<em><u>Given inequality is:</u></em>

We have to solve the given inequality


Whenever we multiply or divide an inequality by a negative number, we must flip the inequality sign

<em><u>Thus the solution to inequality is:</u></em>

Answer:
y+1=3(x-4)
Step-by-step explanation:
Hi there!
We are given a slope of 3 and a point (4,-1).
We need to find the equation of the line in point-slope form
Point-slope form is given as y-y1=m(x-x1), where m is the slope, and (x1,y1) is a point
We have all of the needed information to substitute into the formula
First, let's label the values of everything to avoid any confusion
m=3
x1=4
y1=-1
now substitute into the formula *remember, the formula has SUBTRACTION, and we have a NEGATIVE number, so we'll end up subtracting a negative*
y--1=3(x-4)
simplify
y+1=3(x-4)
That's it!
Hope this helps :)
