Answer: x=4,y=-5

Step-by-step explanation:

Equation: 5x-4y=20

To find the x intercept make y=0 so ur left with

1)5x-4(0)=20

Then you can solve x from here

2) 5x=20

Because -4 * 0 = 0

3) x= 20/5

Because we want x by itself so we divide 5 on both side so the 5 cancels out on the left side

4) x=4

Because 20/5=4

———————————————-

You do the same thing for y make x equal to zero and that’s how you find it

Solve for x 14 x square+7x-6
irina [24]

Answer:

x=0.450765 or x=−0.950765

Step-by-step explanation:

14x² + 7x - 6

→ Find the product, sum and factors

Product = -6

Sum = 7

Factors = No factors

→ Since there are no factors utilise the quadratic formula

\frac{-b+-\sqrt{b^{2}-4ac } }{2a}

→ List the values of a, b and c

a = 14

b = 7

c= -6

→ Substitute into the formula

\frac{-7+-\sqrt{7^{2}-4*14*-6} }{2*14}

→ Simplify

x=0.450765 or x=−0.950765
