Answer:

x-intercept is (5, 0) and the y-intercept is (0, 2)

Step-by-step explanation:

x-intercept: set y = 0 and solve for x: 4x + 0 = 20, so x = 5 and the x-intercept is (5, 0).

y-intercept: set x = 0 and solve for y: 0 + 10y = 20, or y = 2.

The x-intercept is (5, 0) and the y-intercept is (0, 2).

Re-write the quadratic function below in Standard Form<br> y=-3 (x - 2)² – 7

pav-90 [236]

Answer:

$y=-3x^2+12x-19$

Step-by-step explanation:

we know that

The quadratic equation in standard form is equal to

$y=ax^{2} +bx+c$

we have

$y=-3(x-2)^{2}-7$

This is a quadratic equation in vertex form

Convert to standard form

$y=-3(x^2-4x+4)-7$

Apply distributive property

$y=-3x^2+12x-12-7$

Combine like terms

$y=-3x^2+12x-19$ ----> quadratic equation in standard form

ana and christion collect stamps.together they have 500 stamps in their collection. ana has 150 fewer stamps then christian.how

mezya [45]

Lets represent Ana and Christion using the Letters A and C
a+c=500
c=a+150
now substitute c for a+150 back into the first equation
a+a+150=500
a+a=350
2a=350
Divide by two
a=175
Now that we know annie has 175 all we do is subtract that from the total (500)
C=325
Sure enough, 175 is 150 less than 325
Hope that helped, send me a message if you need clearing up :D
