Kipish [7]2 years ago
7 0

Answer: Definitely C (and I'm assuming A since there are 2 answers but I can't see A that well)

Step-by-step explanation: Its not B because B is 7

Its not D because D is 5

Its not E because E is 7

You are looking for -3, so C is the only correct on.

Not sure about A. I can't see it

Change 0.7 to a common fraction
erma4kov [3.2K]

Answer:

7/10

Step-by-step explanation:

In 0.7 we will change the decimal to fraction. First we will write the decimal without the decimal point as the numerator. Now in the denominator, write 1 followed by one zeros as there are 1 digit in the decimal part of the decimal number. Therefore, we observe that 0.7 (decimal) is converted to 7/10 (fraction).

A line includes the points (10, -10) and (1,8). What is its equation in slope-intercept form?
Anettt [7]

Answer:

y=-2x+10

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(8-(-10))/(1-10)

m=(8+10)/-9

m=18/-9

m=-2

------------------

y-y1=m(x-x1)

y-(-10)=-2(x-10)

y+10=-2x+20

y=-2x+20-10

y=-2x+10

Graph this inequality on the number line.<br><br> x ≤ 2.6
pantera1 [17]

x ≤ 2.6 would look like this on the number line, the 2.6 part would be shaded in as well and not left open since x is less than OR EQUAL to 2.6
