Simplify:

20 + 52 × 2

=> 20 + 104

=> 124 Ans.

None of these.

Hey there!

20 + 52 × 2

= 72 × 2

= 72 + 72

= 144

Therefore, your answer SHOULD BE: 144

Good luck on your assignment and enjoy your day!

Answer:

[tex]y = \frac{1}{5} x - 9[/tex]

Step-by-step explanation:

The slope-intercept form is y = mx + b, where:

m = slope

b = y-intercept.

The slope (m) tells you the steepness of the line. It is the average rate of change which measures how the y-value changes for each one-unit change in the x-value. Hence, slope [tex]= \frac{rise}{run}[/tex].  So the given slope of 1/5 means that for every 1 unit change in the y-value, the x-value changes by 5 units (you go up 1 unit, and "run" 5 units to the right).

Next, the y-intercept is the point on the graph where it crosses the y-axis, and has the coordinates, (0, b). It is also the value of y when x = 0. Since you're given the y-intercept of -9, then that means that it is the y-coordinate of (0, b). So, it becomes (0, -9).

Now that we have our slope (m ) = 1/5, and the y-intercept (b ) = -9, we can write the equation of the line as:

[tex]y = \frac{1}{5} x - 9[/tex]

(I'm also including a screenshot of the line where it shows the y-intercept of (0, -9) on the graph).

Answer:

[tex] \frac{3x + 1}{2} - 1 = 2x) \times 2 \\ 3x + 1 - 2 = 2x \\ 3x - 2x = 2 - 1 \\ x = 1 [/tex]

Answer:

[tex]x=1[/tex]

Step-by-step explanation:

[tex]\frac{3x+1}{2}-1=x[/tex]

Add 1 to both sides:

[tex]\frac{3x+1}{2}-1+1=x+1[/tex]

[tex]\frac{3x+1}{2}=x+1[/tex]

Multiply both sides by 2:

[tex]\frac{3x+1}{2}\times \:2=x\times \:2+1\times \:2[/tex]

[tex]3x+1=x\times \:2+2[/tex]

Subtract 1 from both sides:

[tex]3x+1-1=x\cdot \:2+2-1[/tex]

[tex]3x=2x+1[/tex]

Subtract 2x from both sides:

[tex]3x-2x=2x+1-2x[/tex]

[tex]x=1[/tex]

Answer: -27/64

Step-by-step explanation:

flip to multiply by the reciprocal.

becomes:  (-3/8) · 9/8

a negative · a positive makes a negative.

multiply normally, add the negative sign after.

9 · 3 = 27

8 · 8 = 64

new fraction: 27/64 (cannot be simplified form here)

add negative sign.

final: -27/64

Hey there!

y=-2x+3

If x=-6

y=-2(-6)+3

y=12+3

y=15

y=-2(-3)+3

y=6+3

y=9

y=-2(0)+3

y=0+3

y=3

y=-2(3)+3

y=-6+3

y=-3

Hope this helps you! :)

Answer:

if x=-6 y =-10(-6)+3=60+3=63

and if x=-3, y= -10(-3)+3=30+3=33

then if x=0, y =-10(0)+3=0+3=3

finally if x=3 y=-10(3)+3=-30+3=27

Step-by-step explanation:

you are to use the equation given to you, then you should be substituting the value of x in the equation i.e y=-10x+3

Answer:

Y = 2x + 16

Step-by-step explanation:

Y = mx + b

y = 2x + b

10 = 2(-3) + b

10 = -6 + b

16 = b

y = 2x + 16

Answer:

0.45 miles per minute

Step by Step Explanation:

Look at the units:  miles per hour is miles/hour

If we multiply

miles       hour         miles

-----   *     -------  =  ---------

hour       minute      minute

(27 miles/hour)(1/60 hours/minute) = 27/60

= 9/20 = 0.45 miles per minute

Answer:

D. y = |x + 5| - 2

Step-by-step explanation:

The peak of the graph is formed at the point (2, 5)

that means the function must be such that the value of y is 5 when x is 2.

Checking D option:

y= | x + 5| - 2

5 = | 2 + 5| - 2

5 = 7 - 2

5 = 5

LHS = RHS

this means that the given graph is represented by the equation in option D.

Therefore, it's D

_________________

You'll have to check for all options by placing the values of x and y repetitively in all of them.

There, LHS ≠ RHS.

Step-by-step explanation:

First let's put the distance of Pluto in scientific notation:

3,670,000,000 = 3.67•10⁹

Now, to find the time you have to divide the distance by the speed, in this case is the distance from sun to Pluto, and the speed of light:

(1.17•10⁷)÷(3.67•10⁹) = 0.00317 minutes

Now put the result in scientific notation:

0.00317 = 3.17•10-³
