Is about inequalities, I know the rule of flipping the sign if you multiply or divide by a negative numbers but a few examples c

onfuse me.
To make this inequality 5x+2y<14 into the slope-intercept form y=mx+b, please tell me if the sign has to be flipped.
I do it like this
5x+2y<14
y<-5/2x+14/2
y<-5/2x+7
I am not dividing by a negative number but 5 is negative, 2 is positive, should I flip the sign or not?

Answer:

do not flip the sign

Step-by-step explanation:

you only flip when you divide with negative number

however, for you to get the intercepts, you assumed

for y =0

5x +2(0)<14

5x<14

x<14/5<2.8

and also

x=0

5(0)+2y<14

2y<14

y<14/2

y<7

this assumption is because at interception, either x or y will be at origin

For four weeks in June Cameron baked 3 1/4 miles each week and swim 2 1/2 miles each week for three weeks in July he baked 4 3/4
Tems11 [23]
For June:
 Bike:
 (4) * (3 1/4) = 13 miles
 Swim:
 (4) * (2 1/2) = 10 miles
 Total:
 13 + 10 = 23 miles
 For July:
 Bike:
 (3) * (4 3/4) = 14.25 miles
 Swim:
 (3) * (3 1/2) = 10.5 miles
 Total:
 14.25 + 10.5 = 24.75 miles
 The difference between both months is:
 24.75 - 23 = 1.75 miles
 Answer:
 
the total distance Cameron bike and swim in July compared to the total distance he bike in swim in June was 1.75 miles greater

HELP PLEASE I WILL GIVE 100 POINTS TO WHOEVER GIVES ME THE RIGHT ANSWER​
Dovator [93]

Answer:

44°

Step-by-step explanation:

Note that the square in located to the left of the two given intersecting lines denotes that it is a right angle, in which the measurements is 90°.

This means that:

∠α + ∠β = 90°

Let:

m∠α = x

m∠β = 46°

Plug in the corresponding numbers and variable to the given terms:

x + 46 = 90

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 46 from both sides:

x + 46 (-46) = 90 (-46)

x = 90 - 46

x = 44

x = 44° is your answer.
