Jennifer belongs to a gym that requires a monthly membership fee of $100 plus an additional $10 fee for each yoga class she atte

MrRissso [65]

First of all, we need to know what is the slope-intercept form which is:
y=mx+b where m represent slope and b represent y intercept
Then,
Let y represent the total amount of money that Jennifer pays monthly
mx represent the total amount of money that Jennifer pays for classes she attends
b represent the memberships fee, so:
y=10x+100 the following slope-intercept form equations models the total amount that Jennifer pays monthly. Hope it help!

What is the measure of angle A ?<br> what is the measure of angle B ?

lesya692 [45]

Answer:

$\angle\,A=72^o\\\angle\,B=108^o$

Step-by-step explanation:

Notice that buy construction of a parallelogram,the angles $\angle \,A$ and $\angle \,C$ must equal each other. Then, based on the info given, we can write the following equation:

$3\,y+27^o=5\,y-3^o\\27^o+3^o=5\,y-3\,y\\30^o=2\,y\\y=15^o$

Then, angle $\angle \,A$ = $5\,(15^o)-3^o=72^o$ which is also equal to angle B

and since the addition of all internal angles of the parallelogram must equal $360^o$ , then:

$B+D=360^o-72^o-72^o=216^o$

and therefore, since $\angle \,B$ and $\angle \,D$ must be equal, then:

$\angle\,B=\frac{216^o}{2} =108^o$

Help urgently need help

Answer:

$y=\dfrac{8}{7}x - \dfrac{23}{7}$

Step-by-step explanation:

Rearranging the terms, we get $7y=8x-23$ . Dividing both sides by 7, we get $\dfrac{7y}{7} = \dfrac{8x-23}{7}$ , so $\boxed{y=\dfrac{8}{7}x - \dfrac{23}{7}}$
