Answer:

0.2 or 1/5

Step-by-step explanation:

-4(50x - 20) = 10x + 15 + 23

-200x + 80 = 10x + 38

80 = 210x + 38

42 = 210x

0.2 = x

Hope this helps! Pls give brainliest!

Answer: x = 1/5 or 0.2

Step-by-step explanation:

-4(50x-20)=10x+15+23

-200x +80=10x+38

-80 -80

-200x=10x-42

-10x. -10x

-210x = -42

/-42. /-42

= 5

Need urgent help in mathematics!! Will mark brainliest!!!!

Simply find the total medium cofees sold
then divide that by the number of medium cofees that weren't caffeinated

so..
$66 \div 44 = x$
then
$100 \div x = percentage$

so x will be 1.5 & 100 ÷ 1.5 = 66.666...
rounded is 67%

$67\%$

How do you find a volume of a cube and Rectangular prism and a cylinder? PLEASE HELP ASAP ASAP PLEASSEEEEEEE I BEG YOU

Nat2105 [25]

Of course!

Cube: side length * side length * side length

So if it's a 6x6x6 cube, it's 6*6*6 = 216

Rectangular Prism: side length * side height * base width

So if it's a 6x7x8 prism, it's 6*7*8 = 336

Cylinder: π * (radius squared) * height

So if the base's radius is 6 and the height is 7, it's π*6^2*7 = 252π

Question 1 of 10

Archy [21]

Answer:

A. y = 7(x + 1)²-3

Step-by-step explanation:

Parabola:

$y = 7x^{2} + 14x + 4$

$y = 7(x^{2} + 2x) + 4$

Putting into vertex form, remember that:

$(x + a)^{2} = x^{2} + 2ax + a^{2}$

In this question:

$x^{2} + 2x$ , to put into this format:

$x^{2} + 2x + 1 = (x + 1)^{2}$

We add one inside the parenthesis to do this. The parenthesis is multiplied by 7, so for the equivalent, we also have to subtract 7. Then

Vertex form:

$y = 7(x^{2} + 2x + 1) + 4 - 7$

$y = 7(x + 1)^{2} - 3$

So the correct answer is:

A. y = 7(x + 1)²-3
