Write the equation of a line perpendicular to the line y = 2x - 3 that goes through point (4,3). Convert the line to Slope-Inter
timama [110]

Answer:

y=-1/2x+5

Step-by-step explanation:

a line perpendicular to a given line will have a slope that is the negative reciprocal of the given one. this means the slope of the line perpendicular to the given one would be -1/2.

How I got this: 2 as a fraction would be 2/1, so the reciprocal would be 1/2, but we want the NEGATIVE reciprocal, so we multiply the fraction by -1, which gets us -1/2.

Now we know the slope of the equation that passes through (4,3) which is perpendicular to the given line.

y=-1/2x+b

b is the y-intercept, so we use the point (4,3) and the slope we were given to find out b.

when the point's x value is 0, the y value is the y intercept.

A group of boys and girls were surveyed on their favorite football team. 5 more boys favored the Giants compared to the girls. A
tiny-mole [99]

Answer: 19 boys and 14 girls liked the Giants.

Step-by-step explanation:

Let be "b" the number of boys who liked the Giants and "g" the number of girls who liked the Giants.

Based on the information given, set up a system of equations:

\left \{ {{b+g=33} \atop {b=g+5}} \right.

Use the Substitution method to solve this system of equations.

First, you must substitute the second equation in the first equation and solve for "g":

(g+5)+g=33\\\\2g=33-5\\\\g=\frac{28}{2}\\\\g=14

<em> </em>And finally, you must substitute the value of "g" into the second equation in order to find the value of "b".

Then:

b=(14)+5\\\\b=19

Gerry folded 3 out of 8 of the pile of shirts molly folded 1out of 8 of the pile of shirts together did they fold more than half
Tpy6a [65]
Gerry folded 3/8 of the pile of shirts and Molly folded 1/8 of the pile of shirts, so in total they folded 4/8 of the pile of shirts.

4 is half of 8, but it is not more than half of 8, so, together, Gerry and Molly did NOT fold more than half the shirts.
