Answer:

Multiply the -10 by all the numbers in the bracket.... Just expand the bracket and simplify.

Remember <u>-x- = positive and -x+=negative</u>

1) -10-60x

-10-60x=0

-60x=10

x=-10/60

x=1/6

2) -16x+14

-16x+14=0

-16x=14

x=-14/-16

x=7/8

3) 42x-18

42x-18=042x=18

x=18/42

x=3/7

4)24x-24

24x-24=0

24x=24

x=24/24

x=1

In order : Bracket power division multiplication addition subtraction
Means BODMAS
1. -10-60x
2. -16x+14
3. 42x-18
4. 24x-24
Why + and - are different
Remember this
- ( multiplies to) - = +
- (multiplies to ) + = - ( and vice versa)

Take a factor out of the square root:

Andrews [41]

Answer:

1. |y| sqrt(10)

2. |x| sqrt(x)

3. a^2 sqrt(a)

4. 4 |y|^3 sqrt(3)

5. 1/4 *|x| sqrt(3x)

Step-by-step explanation:

1. sqrt(10y^2)

We know that sqrt(ab) = sqrt(a) sqrt(b)

sqrt(y^2) sqrt(10)

|y| sqrt(10)

We take the absolute value of y because -y*-y = y^2 and the principle square root is y

2. sqrt(x^3)

We know that sqrt(ab) = sqrt(a) sqrt(b)

sqrt(x^2) sqrt(x)

|x| sqrt(x)

3. sqrt(a^5)

We know that sqrt(ab) = sqrt(a) sqrt(b)

sqrt(a^4) sqrt(a)

a^2 sqrt(a)

4. sqrt(16 y^7)

We know that sqrt(ab) = sqrt(a) sqrt(b)

sqrt(16) sqrt(y^6)sqrt(y)

4 |y|^3 sqrt(3)

5. sqrt(3/16x^3)

We know that sqrt(ab) = sqrt(a) sqrt(b)

sqrt(1/16) sqrt(x^2)sqrt(3x)

1/4 *|x| sqrt(3x)

Use the drawing tools to graph the solution to this system of inequalities on the coordinate plane.

gtnhenbr [62]

The solution to the system of inequalities is (0.667, 5.333)

<h3>How to graph the inequalities?</h3>

The system of inequalities is given as:

y > 2x + 4

x + y ≤ 6

Next, we plot the graph of the system using a graphing tool

From the graph, both inequalities intersect at

(0.667, 5.333)

Hence, the solution to the system of inequalities is (0.667, 5.333)

WILL MARK BRAINLIEST PLEASE HELP ASAP !!! Roberto is paid $11 an hour at his new job He wishes to graph his total pay T, as a fu

Oliga [24]

To best show this information, the scale for the <em>T</em>-axis of his graph should go from 0 to at <em>least </em>11, and the <em>h</em>-axis of his graph should go from 0 to at <em>least </em>40.

Apologies for any incorrect answer, hope this helped.

If h(x)=(fog)(x) and h(x) = sqrt x+5, find g(x) if f(x) = sqrtx+2

Katen [24]

Answer: The value of g(x) is x+3.

Step-by-step explanation:

Since we have given that

$h(x)=f\circ g(x)$

Here,

$h(x)=\sqrt{x+5}\\\\and\\\\f(x)=\sqrt{x+2}$

We need to find the value of g(x):

$f(x)=\sqrt{x+2}\\\\f(g(x))=\sqrt{g(x)+2}\\\\h(x)=\sqrt{g(x)+2}\\\\\sqrt{x+5}=\sqrt{g(x)+2}\\\\x+5=g(x)+2\\\\g(x)=x+5-2=x+3$

Hence, the value of g(x) is x+3.
