Write the following inequality in slope-intercept form. 5x-5y>70
SCORPION-xisa [38]

The given inequality 5x - 5y > 70 when written in Slope intercept form is gotten as; y < x + (-14)

<h3>How to write slope intercept form?</h3>

The formula for equation of a line in slope intercept form is given by;

y = mx + c

where;

m is slope

c is y-intercept

We are given the inequality as;

5x - 5y > 70

Thus;

Subtract  5x from both sides to get;

-5y > 70 - 5x

divide both sides by -5 to get

y < x + (-14)

dane used a ruler and a protractor to draw a rhombus with a side of 4 cm inlength and an angle that measures 110 degrees choose
lara [203]

Answer:

 70 °

Step-by-step explanation:

We have that one side of the rhombus is equal to 4 cm and an angle of the rhombus is 110 degrees. We know that the adjacent sides of a rhombus are supplementary, which means that the sum of the angles must be 180 degrees.

We can assume that the other angle is x.

110 ° + x = 180 °

x = 180 ° -110 °

x = 70 °

The measure of the missing angle on the diagram will be 70 °.
