We know that
The <span>abscissa is the x coordinate and the ordinate is the y coordinate
</span>so
for x=1.2
<span>8x–5y=14------> 8*1.2-5y=14-----> 5y=9.6-14-----> 5y=-4.4----> y=-0.88
the answer is
the ordinate is -0.88

- All angles in a triangle add up to 180°
Step-by-step explanation:
<u>Step 1: Set Up Equation</u>
53° + 97° + x° = 180°
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine Like Terms: x° + 150° = 180°
- Isolate <em>x</em>: x = 30°
Answer:
6 inches
Step-by-step explanation:
The formula for the area of a triangle is

b - base
h - height
the first step is to add the information that we know into the formula.
We know the area =
and the height = 5 inches

if we had both the base and the height, the next step would be to multiply
b x h then half the answer to work out the area but as we already have the area (
) we need to work in reverse.
15 x 2 = 30
what is 5 multiplied by to get 30?
5 x ? = 30
30 ÷ 5 = 6
∴ the base = 6inches
to check if our answer is correct, we can place these numbers into the formula
A = 
A =
(30 ÷ 2 = 15)
A = 15
