Answer:
z = 10°
Step-by-step explanation:
Since the two sides are equal, the two base angles have to be equal
That means that 5z and 130 form a straight line and add to 180 degrees
5z+130 = 180
Subtract 130 from each side
5z = 50
Divide by 5
5z/5 = 50/5
z=10
To find the y-intercept, we can convert this to slope-intercept form, or replace the value of x with 0 and solve for y.
We'll do both first.
-x + 5y = 45
5y = 45
Divide both sides by 5.
y = 9
Now let's convert it to slope-intercept.
-x + 5y = 45
Add x to both sides.
5y = 45 + x
Divide both sides by 5.
y = 1/5x + 9
y = 9
<h3><u>The y-intercept of our line is 9.</u></h3>
Just try different ways to find a common denominator, add from there and then simplify.
Answer:
f=4
Step-by-step explanation:
1) first we have to get the "f" by itself. to do this we subtract the 1 from the right side of the equation.
2) and what you do to one side you ALWAYS do to the other side!!! so subtract 1 from the 5 also
3) this leaves you with 4=f
hope this helps!
Answer:
288
Step-by-step explanation:
the formula is 2(lw+wh+hl)
length - 8
width - 8
height 5
substitute the values and you get
2(64+40+40)
2(144)
= 288
