2E5 in scientific notation

Answer:

-1

Step-by-step explanation:

The change in y between x=-1 and x=2 is -3 and -3/3=-1 so the slope is -1

Answer:

-1

Step-by-step explanation:

Use any 2 points on the line.

Let's use (10, -6) and (2, 2).

slope = (difference in y)/(difference in x)

slope = (-6 - 2)/(10 - 2)

slope = -8/8

slope = -1

Answer:

28√3

Step-by-step explanation:

√12 + √12 + 4√27 + 4√27 = 28√3

Answer:

B)

Step-by-step explanation:

we are given a logarithmic expression

we want to expand it

in order to do so we can consider using

recall that,

[tex] \displaystyle \sqrt{x} = {x}^{ \frac{1}{2} } [/tex]

thus rewrite

[tex] \displaystyle \log_{ \sigma} \bigg( \frac{57}{74} \bigg) ^{ \large\frac{1}{2} } [/tex]

use division logarithm property

[tex] \displaystyle \log_{ \sigma}(57) ^{ \large\frac{1}{2} } - \log_{ \sigma}(74)^{ \large \frac{1}{2} } [/tex]

use exponent logarithm property:

[tex] \displaystyle \frac{1}{2} \log_{ \sigma}(57) ^{ \large } - \frac{1}{2} \log_{ \sigma}(74)^{ \large } [/tex]

and we are done!

Answer:

10 x² - 4x

Step-by-step explanation:

Area trapezoid = 1/2 ( (b1+b1)h)

1/2( 2x * 10x - 4)

1/2(20x² - 8x)

10x² - 4x

If you count up and sideways, it would be 12, but then there is some stuff we need to calculate at the end because it's not fully.

Answer:

B , 8.6

Step-by-step explanation:

5^2 + 7^2 = 74

square root of 74 is 8.6 hen rounded

I just learned about this lol its the Pythagorean theorem

Hi, there your answer will be C. y=33/2x+425

Step-by-step explanation:

I tired uploading the picture on how I got my answer, but it keep saying inaapriate words which I didn't even said anything bad, but yeah trust me the answer is right.

Answer:

For "I have a Dream", it is focused on America as a whole and to one day have people of all races to be treated equally. Letter from a Birmingham Jail was focused more on a group of white clergy.

Answer:

for number 5 Subtract 18 from both sides of the equation

4+18−18=30−18

for number 1 Subtract 7 from both sides of the equation

so number 3 subtract 3 from each side and so on hope it helps

im not sure how to explain it but--

for example.. the first one

1) y + 7 = 12

first, you subtract 7 from both sides

so-- you'll subtract 7-7 on the left and 12-7 from the right

now, you have y by itself since 7-7 = 0

y = 12-7, or y = 5

also its important to note that when the equation is like 2) and uses subtraction (x-4) instead of addition (y +7)-- then you add to both sides

so for 2)-- you'd add 4 to both sides for 4 to cancel out to equal 0

your goal is always to isolate the variable on one side

Answer:

80%

Step-by-step explanation:

Step 1: Add the given data

588 + 147 = 735

Step 2: Divide the number of students who bought a school shirt by the total number of students

588 ÷ 735

= [tex]\frac{735}{588}[/tex]

= 0.8

Step 3: Convert the decimal to fraction

0.8 = 80% (Move the zero 1 place behind the number and remove the ".")

Or

0.8 × 100 = 80%

Therefore, 80% of students bought a school shirt.

Answer:

The answer is -5/24.

Step-by-step explanation:

Answer:

A = -5/24

Step-by-step explanation:

1/2 (1/4 - 2/3)

1/2 (3/12 - 8/12)

1/2 (-5/12)

= -5/24

Answer:

n=7

Step-by-step explanation:

6(n-3) - 2n=10

Distribute

6n - 18 -2n = 10

Combine like terms

4n -18 = 10

Add 18 to each side

4n-18+18 = 10+18

4n = 28

Divide by 4

4n/4 = 28/4

n = 7

Answer:

N = -8

Answer:

Midpoint is[tex](-25.15,10.2)[/tex]

Step-by-step explanation:

A line segment refers to line that has two endpoints.

Let [tex](a,b),(c,d)[/tex] be the endpoints of a line segment.

Midpoint of the line segment is given by [tex](\frac{a+c}{2} ,\frac{b+d}{2})[/tex]

Take the given points as follows:

[tex](a,b)=(-24.6,38.1)\\(c,d)=(-25.7,-17.7)[/tex]

Midpoint of a line segment [tex]=(\frac{-24.6-25.7}{2},\frac{28.1-17.7}{2})[/tex]

[tex]=(\frac{-50.3}{2} ,\frac{20.4}{2} )\\=(-25.15,10.2)[/tex]
