Answer:
Blues Paints = 2.45 pints
Step-by-step explanation:
Let's generate an expression that would relate all the variables given:
Total pints of paints used:
9.8 = white + blue
Pints of white paint used:
= 3/4 of 9.8
=0.75 * 9.8
=7.35
Number of pint of BLUE PAINTS used:
9.8 = White Paints + Blue Paints
9.8 = 7.35 + Blue Paints
Blue Paints = 9.8 - 7.35
Blues Paints = 2.45
Kate used 2.45 pints Blues Paints for her bedroom
It would be subtraction I think
Answer:
x = 64°
Step-by-step explanation:
180° in half a circle or a line.
There is also 180° in a triangle.
So the other 2 angles of the triangle equal x.
34° + 30° = 64°
distributinve, multiplying from parenthesece
Answer:
vertex = (- 10, - 10 )
Step-by-step explanation:
The equation of a quadratic in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
To obtain this form use the method of completing the square.
Given
h(x) = x² + 20x + 90
add/subtract ( half the coefficient of the x- term )²
h(x) = x² + 2(10)x + 100 - 100 + 90
= (x + 10)² - 10 ← in vertex form
with (h, k ) = (- 10, - 10 )
