Answer:

y intercept : 1

slope : 3x

Step-by-step explanation:

to find y-int just see where the line crosses on the y-axis and for slope just count how many go up/dow and how far left/ right it goes. rise / run

Answer:

2/3

Step-by-step explanation:

In the game of chance, the possibility of winning it is 1/3. This is one of two outcomes, winning or losing. Since there is a 1/3 chance of winning it, there leaves only one outcome, losing it. Since 1/3 is a third of a whole, that leaves 2/3 for the other possibility, losing it. We then find that winning it has the chance of 1/3 and losing it has a 2/3 chance.

Solve for r. s=2πrh

Butoxors [25]

Answer:

s/2πh =r

Step-by-step explanation:

s=2πrh

Divide both sides by 2πh to isolate r

s/2πh =2πrh /2πh

s/2πh =r

The height of a triangle is 3cm less than twice the base. The area is 10cm2

Kamila [148]

Answer:

The base is 4cm and the height is 5cm.

Step-by-step explanation:

This is a solve the system question. Call H the height of the triangle and B the base. The question tells us:

$H=2B-3$

and

$\frac{B \times H}{2}=10$

Sub the first equation into the second (as H is already isolated). You will end up with a quadratic equation - solve that any way you wish (e.g. quadratic formula). I've provided the factored form below which shows you the roots:

$\frac{B(2B-3)}{2}=10\\\frac{2B^2-3B}{2}=10\\2B^2-3B=20\\2B^2-3B-20=0\\(2B+5)(B-4)=0\\B= - \frac{5}{2},4$

In this question, we take B=4. You can't have a negative side length so the other answer is eliminated. Now sub the value for B into either of the original equations. I'll use the first, again because H is already isolated:

$H=2(4)-3\\H=8-3\\H=5$
