1/2 plus what equals 7/8

1 answer:

4 0

11/8 or 1 3/8

You must have the same denominator. Therefore, multiply 1/2 by 4 to get a denominator of 8. Be sure to do this for the numerator as well. You end up with 4/8 plus 7/8. You result with 11/8 or simplified 1 3/8.

F(x)= x^3 -2 g(x)= 3x+2 Find f(0) + g(0)

Anestetic [448]

Answer:

Step-by-step explanation:

f(0) is -2 because 0^3 is 0. and 0 - 2 is -2. g(0) is 2 because 3(0) is 0. 0+2 is 2. and -2 + 2 is 0. Hope this helps :)

the equation of the line that is perpendicular to the line with equation y=-2x-1 and passes through the point (1, -2) is?

kolezko [41]

Answer:

$y=\frac{1}{2} x-\frac{5}{2}$

Step-by-step explanation:

Hi there!

Note that:

Linear equations are typically organized in slope-intercept form: $y=mx+b$ where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)
Perpendicular lines always have slopes that are negative reciprocals of each other (ex. 3 and -1/3, 5/6 and -6/5, etc.)

1) Determine the slope (m)

When we look at the given line, $y=-2x-1$ , we can identify that -2 is in the place of m, the slope of the line. Because perpendicular lines are negative reciprocals of each other, we know that a line perpendicular to this would have a slope of $\frac{1}{2}$ . Plug this into $y=mx+b$ :

$y=\frac{1}{2} x+b$

2) Determine the y-intercept (b)

$y=\frac{1}{2} x+b$

Plug in the given point (1,-2)

$-2=\frac{1}{2}(1)+b\\-2=\frac{1}{2}+b$

Subtract 1/2 from both sides

$-2-\frac{1}{2}=\frac{1}{2}+b-\frac{1}{2}\\-\frac{5}{2} = b$

Therefore, the y-intercept of the line is $-\frac{5}{2}$ . Plug this back into $y=\frac{1}{2} x+b$

$y=\frac{1}{2} x-\frac{5}{2}$

I hope this helps!

Which number is the additive inverse of -5?

Marysya12 [62]

Answer:

It would be 5

Step-by-step explanation:

SO the additive inverse would basically just be the opposite of the number, for example lets say you had 12, the additive inverse would be -12. You're just changing the sign of the number! From what i know i believe that's it. Have a nice day! :D
