The x would be 13, explanation: each value from the smaller polygon is multiplied by 4 to equal the value of the corresponding area on the larger polygon, 2.5 multiplied by 4 is 10, 13 - 3 equals 10, therefore x is 13 :)

Given functions f and g, find f-g.

Eva8 [605]

Answer:

$-5x-5$

Step-by-step explanation:

original functions:

$f(x)=3x-8\\g(x)=8x-3$

Subtract the polynomials:

$f(x)-g(x) = (3x-8) - (8x-3)$

Distribute the negative sign:

$3x-8-8x+3$

Combine like terms:

$(3x-8x)+(-8+3)$

Add like terms:

$-5x-5$

-4x + 7 = 2y - 3<br> y-intercept:<br><br> x intercept:

pantera1 [17]

Answer:

x-intercept: $\bigg(\frac{5}{2}, \:0\bigg)$

y-intercept: $(0,\:5)$

Step-by-step explanation:

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

$-4x + 7 = 2y - 3$

$-4x+7=2\left(\bold{0}\right)-3$

Simplify 2(0): $-4x+7=2\cdot \:0-3$

Subtract 0 - 3 = -3: $-4x+7=-3$

Subtract 7 from both sides: $-4x+7-7=-3-7$

Simplify: $-4x=-10$

Divide both sides by -4 $\frac{-4x}{-4}=\frac{-10}{-4}$

$\bold{x=\frac{5}{2}}$

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

$-4x + 7 = 2y - 3$

$-4(\bold{0})+7=2y-3$

Switch sides: $y-3=-4\left(0\right)+7$

Simplify -4(0): $2y-3=-0+7$

Add 3 to both sides: $2y-3+3=7+3$

Simplify: $2y=10$

Divide both sides by 2: $\frac{2y}{2}=\frac{10}{2}$

$\bold{y=5}$
