Y = -4x - 5.....(0,?)...so we know x = 0, so sub in 0 for x and solve for y
y = -4(0) - 5
y = -5....so one point is (0,-5)
do the same for the other points and u get (1,-9) , (-1,-1)
y = -4x - 5.....slope is -4 and ur y int (where ur line crosses the y axes) is (0,-5).
to find the x int (where the line crosses the x axes), sub in 0 for y and solve for x.
0 = -4x - 5
4x = -5
x = -5/4.....or - 1 1/4(for graphing purposes)...x int is (-5/4,0)
so plot all ur points and connect the dots
============================
4x + 9y = 0...(-9,?)..so x = -9..so sub in -9 for x and solve for y
4(-9) + 9y = 0
-36 + 9y = 0
9y = 36
y = 36/9
y = 4...so ur point is (-9,4)
do the same for the others and ur points are : (0,0) , (9,-4)
4x + 9y = 0
9y = -4x....so ur slope is -4 and ur y int is (0,0)
ur x int is : (0,0)....so basically u have a line going through the origin (0,0)
plot all ur points and connect the dots
Hi U can look for calculators online for help they are very good
Hello!
<h2>Answer:</h2>
<h2>__________________________________</h2><h2>Explanation:</h2>
We already know that the formula for area of a rectangle is A = l × w.
Notice how the width and the length are being multiplied to find the area.
Well, to find the width, we must do the <em>opposite</em> of multiplication, which is division.
Since we already have the length, all we have to do is divide the area by the length for each of the questions.
1:
A = l × w
55.5 = 9.25 × w
= 6
2:
A = l × w
48.75 = 7.5 × w
= 6.5
3:
A = l × w
44 = 5 × w
= 8.8
4:
A = l × w
31.25 = 5 × w
= 6.25
Answer:
98 degrees
Step-by-step explanation:
Construct a line parallel to the 2 given lines that passes through the vertex of angle 1.
We get the part of angle 1 below this line is 180 - 144 = 36 by same side interior angles.
We get the part of angle 1 above this line is 62 degrees by alternate interior angles.
meaning the total measure of angle 1 is 62 + 36 = 98
