Answer:

Step-by-step explanation:

one half times (four plus eight)

Writing mathematically

1½ ( 4+8)

Using BODMAS

we'll take the bracket first

1½ × 12

Change 1½ to improper fraction = 3/2

3/2 × 12 = 3×6

= 18

I hope this was helpful, please mark as brainliest

Answer: 6.

Step-by-step explanation: First, answer the question in the brackets, that equals 12. Take the 12 and multiply it by 1/2. When you do this, you are basically dividing it by 2, which gives you 6.

Hope this helps!

What is 3x3 – 11x2 – 26x + 30 divided by x – 5?

ahrayia [7]

Hello :
3x3 – 11x2 – 26x + 30 divided by x – 5 is :3x2 + 4x – 6
because :
(x-5)(3x²+4x-6)=3x^3+4x²-6x-15x²-20x+30 =3x3 – 11x2 – 26x + 30

Answer:

A- control group

Since group A is tested under normal condition, it is the control group. Control group is separated from other groups so that the independent variable being tested cannot influence the result.

What is the equation of the line that passes through the point (-2,5) and has a slope of -4?

adoni [48]

Answer:

$\boxed {\boxed {\sf y= -4x -3}}$

Step-by-step explanation:

We are asked to find the equation of a line given a point and the slope. We will use the point-slope formula.

$y-y_1= m(x-x_1)$

In this formula, m is the slope and (x₁, y₁) is the point the line passes through. The slope of this line is -4 and the line passes through (-2,5).

m= -4
x₁= -2
y₁ = 5

Substitute the values into the formula.

$y-5 = -4 (x--2)$

$y-5 = -4 (x+2)$

We are finding the equation of the line, so we should find the slope-intercept form or y=mx+b ( where m is the slope and b is the y-intercept).We must isolate the variable y on one side of the equation.

First, distribute the -4 on the right side of the equation. Multiply each term inside the parentheses by -4.

$y-5=( -4 *x ) + (-4* 2 )$

$y-5 =(-4x)+ (-8)\\y-5= -4x -8$

5 is being subtracted from y. The inverse operation of subtraction is addition, so we will add 5 to both sides of the equation.

$y-5 =-4x -8 + 5$

$y= -4x -3$

The equation of the line is y= -4x -3. The slope of the line is -4 and the y-intercept is -3.

X =x=x, equals ^\circ ∘ degrees

Andrej [43]

Step-by-step explanation:

x = 145°

we don't even need the upper parallel line with the 35° angle.

it is simply based on the fact that the angles on both sides of 2 intersecting lines have to be the same (just left-right mirrored).
