Y-6=4(x+5) what is y and x intercept?
Law Incorporation [45]

Answer:

x = (-\frac{13}{2} ,0) y = (0,26)

Step-by-step explanation:

First find the x intercept

To find the x intercept, substitute 0 for y and solve for x.

(0)-6=4(x+5)

Rewrite the equation as 4(x+5)=(0)-6

4(x+5)=(0)-6

Subtract 6 from 0.

4(x+5)=-6

Divide each term in 4(x+5)=-6 by 4.

\frac{4(x+5)}{4} =\frac{-6}{4}

Cancel the common factor of 4.

x+5=\frac{-6}{4}

Simplify \frac{-6}{4}

x+5=-\frac{3}{2}

Subtract 5 from both sides of the equation.

x=-\frac{3}{2} -5

To write -5 as a fraction with a common denominator, multiply by \frac{2}{2}

x=-\frac{3}{2}-5 · \frac{2}{2}

Combine -5 and \frac{2}{2}.

x=-\frac{3}{2} +\frac{-5*2}{2}

Combine the numerators over the common denominator.

x=\frac{-3-5*2}{2}

Simplify the numerator.

x=\frac{-13}{2}

Move the negative in front of the fraction.

x=-\frac{13}{2}

x = (-\frac{13}{2} ,0)

-----------------------------------------------------------------------------------------------------

Find the y-intercepts.

To find the y-intercept(s), substitute in 0 for x and solve for y.

y-6=4((0)+5)

Add 0 and 5.

y-6=4 *5

Multiply 4 by 5.

y-6=20

Add 6 to both sides of the equation.

y=20+6

Add 20 and 6.

y=26

y = (0, 26)

Ivan and tanya share £150 in the ratio 4:1 how much more ivan gets compared to tanya
shusha [124]

Answer:

Given statement: Ivan and Tanya share £150 in the ratio 4:1

let the number be x.

Then, the share of Ivan be 4x and the share of Tanya be x.

From the given scenario,

the equation that would best represent the given will be;

4x+x =\£150

Combine like terms;

5x =\£150

Divide both sides by 5 we get;

\frac{5x}{5}=\frac{\£150}{5}

Simplify:

x =£30

Then,

the share of Ivan is, 4x = 4 \cdot 30 =\£120

and the share of Tanya is, x =£30

Therefore, £90 more Ivan gets compared to Tanya.
