How do you graph:<br><br> y≤−4x+40 <br><br> and <br><br> y≤10
Arturiano [62]

Answer:

See attached picture.

Step-by-step explanation:

To graph linear inequalities, use the y=mx + b form to graph using the slope and y-intercept.

y ≤ -4x + 40 has slope -4 and y-intercept (0,40).

Start at (0,40) and mark it. Then move down 4 units and to the right 1. Mark this point at (1,36). Connect the points with a solid line since the inequality has equal to. Substitute a point like (0,0) to test where the solution set is.

0 ≤ -4(0) + 40

0 ≤ 0 + 40

0 ≤ 40

This is true so shade to the left of the line.

To graph y ≤ 10 mark a point on the y-axis at (0,10). Draw a horizontal solid line through the point. Then shade below the line.

PLEASE HELP ASAP!! WILL GIVE BRAINLIEST!!

Given is :

The area of the rectangular patio is = 130 square feet

Let the width of the patio be = x feet

As length is 3 feet more than the width, so the length is = x+3 feet

Now area of rectangle is = length * width

x(x+3)=130

x^{2}+3x=130

x^{2}+3x-130=0

x^{2}+13x-10x-130=0

x(x+13)-10(x+13)=0

(x-10)(x+13)=0

This gives either x-10=0 or x+13=0

x-10=0 ; x=10

x+13=0 ; x=-13 (neglect this negative value)

So, the width of the patio is = 10 feet

Length = 10+3 = 13 feet

I don't understand how to find a. Please help!

The small right angled triangle with hypotenuse vale 5 is similar to the big triangle with b as the hypotenuse
Corresponding sides are in the same ratio so we can write 
a/12 = 5/b.....(1)

Also  applying pythagoras theorem to the large triangle 
b^2 = 5^2 + 12^2
b^2 = 169
b = 13

So substituting in equation (1):-
a  / 12 = 5  / 13
a = (5*12 ) / 13
