Answer all of them pls

1. 3x+-4 > 17 (c)

2. 3x+-4 < 17 (b)

3. 3x+-4 < 17 (d)

4. 3x+-4 < 17 (d)

5. 3x+-4 > 17 (a)

Step-by-step explanation:

The sum of three times a number is 3.

and -4 is +-4.

Greater than is >. Meaning it can not be any number under 17.

Less than is <. Meaning it can not be higher than 16.

At most is <. Meaning it HAS to be 17 or less.

No more than is <. Meaning it HAS to be 17 or less.

At least is >. Meaning it could be more than 17.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
