System of linear equation for graph below

Mathematics
1 answer:
Andrej [43]2 years ago
5 0

Answer: See below

Step-by-step explanation:

For the line on top, we know the slope is negative because it is going down. We can find the slope by counting how much the point goes down and to the right. Y-intercept is the point on the y-axis.

slope: -3

y-intercept: 2

Now that we have the slope and y-intercept, we know the equation is y=-3x+2.

For the second line, we know the slope is positive because it is going up. Since slope is rise/run, we can see it rises 1 unit and runs to the right by 2 units. Y-intercept is the point on the y-axis.

slope: 1/2

y-intercept: -5

With our slope and y-intercept, we know our equation.

y=1/2x-5

What number needs to be added to 5 and 3 so that the ratio of the first number to the second
Mashcka [7]

Answer:

3

Step-by-step explanation:

Choose a variable to represent the number to be added to 5 and 3.

\frac{5+x}{3+x}=\frac{4}{3}

"Cross-multiply."

3(5+x)=4(3+x)\\\\15+3x=12+4x\\\\15=12+x\\\\3=x

Check:  The ratio of 5+3 to 3 + 3 is 8:6, equal to the ratio 4:3.

Step-by-step explanation:

It appears that given geometrical shape is a HEXA-DECAGON or a 16 sided polygon.

Measure of one interior angle of hexa-decagon can be given as:

\frac{(n - 2) \times 180 \degree}{n}  \\  \\  =   \frac{(16 - 2) \times 180 \degree}{16} \\  \\  =   \frac{14 \times 45 \degree}{4} \\  \\ =   \frac{7 \times 45 \degree}{2} \\  \\  = \frac{315 \degree}{2}  \\  \\  = 157.5\degree \\
