4)
Area=(base x height) / 2
area=24 in²
therefore:
(b*3b)/2=24 in²
3b²/2=24 in²
b²=(24*2)/3 in²
b²=16 in²
b=√(16 in²)= 4 in

answer: 4 in

5)
if x=9
x²+z=103
(9)²+z=103
81+z=103
z=103-81=22

if x=-9
(-9)²+z=103
81+z=103
z=103-81=22

Answer: 23

Solve each equation 3m-3/5=2m-1/2

Kazeer [188]

Answer:

m= 1/10

Step-by-step explanation:

1. Move the terms so that will be 3m - 2m=-1/2 + 3/5

2. Subtract the m values so that will be 3m - 2m= 1 or m

3. Calculate the sum.

4. So the answer will be m= 1/10. M because we subtracted 2 from 3 which make us 1 so we say it m and 1/10 by doing 1/2 + 3/5.

1. Refer to the equation 2x - 4y = 12

Masja [62]

The coordinate pair can be obtained from the given equation by

rearranging the equation to make <em>y</em> the subject of the equation

The table of values obtained from the given equation is presented as follows;

$\begin{array}{|c|cr|} \mathbf{x}&&\mathbf{y}\\0&&-3\\1&&-2.5\\2&&-2\\3&&-1.5\\4&&-1\end{array}\right]$

The graph showing the points in the above table is attached

Reason:

The given equation is presented as follows;

2·x - 4·y = 12

(a) The values are found by making either <em>x</em>, or <em>y</em> the subject of the

formula, and inputting values as follows;

2·x - 4·y = 12

= 4·y

4·y = 2·x - 12

$\dfrac{4\cdot y}{4} = \dfrac{2 \cdot x - 12}{4}$

The rearranged equation is therefore

$y = \dfrac{x }{2} - 3$

Plugging in values of <em>x</em>, (0, 1, 2, 3) to find the corresponding y-values gives;

x = 0

$y = \dfrac{0 }{2} - 3 = -3$

x = 1

$y = \dfrac{1 }{2} - 3 = -2 \dfrac{1 }{2}$

x = 2

$y = \dfrac{2 }{2} - 3 = -2$

x = 3

$y = \dfrac{3}{2} - 3 = -\dfrac{3}{2} = -1.5$

x = 4

$y = \dfrac{4}{2} - 3 = -1$

<u>The table of values</u> is therefore;

$\begin{array}{|c|cr|} \mathbf{x}&&\mathbf{y}\\0&&-3\\1&&-2.5\\2&&-2\\3&&-1.5\\4&&-1\end{array}\right]$

The <u>graph of the points</u> can be <u>plotted</u> using MS Excel as presented here
