Graph the line with slope 1/3

passing through the point (-2, 5).

Answers

Answer:

y = 1/3x + 17/3

Step-by-step explanation:

Required answer: Below

Detailed explanation:

Let's find the equation of the line first.

We know that the line:

  • has a slope of 1/3
  • passes through (-2,5)

So, we use these pieces of information and plug them into the formula:

\bf{y-y_1=m(x-x_1)}

\bf{y-5=(1)/(3)(x-(-2)}

\bf{y-5=(1)/(3)(x+2)}

Now let's graph it.

kirby often forgets to switch the inequity sign when dividing a negative. when solving 3x-10≥x, should kirby collect the variables on the left or the right? why?

Answers

You should collect the variable on the left side since you can't have two variables of the same letter on each side.so you would take the variable from the right side and subtract it from the left. So subtract x on both sides. Your new problem is 2x-10 is greater than or equal to 0. Now you add 10 on both sides. Your new problem is 2x is greater than or equal to 10. Now divide by 2 on both sides. Your answer would be x is greater than or equal to 5

15 is 2 1/2 of what number?

Answers

15 is 2 1/2 of a number 6.

We need to find that 15 is 2 1/2 of what number.

What is the meaning of 'of' in maths?

In math, 'of' is also considered one of the arithmeticoperations which means multiplication within the brackets.

Let the unknown number be y.

Now, 2 1/2 of y=15

⇒5/2 ×y=15

⇒y=6

Therefore, 15 is 2 1/2 of 6.

▪ Answer:

n = 6

▪ Step-by-step explanation:

n × 2 1/2 = 15

n × 5/2 = 15

n × 5 = 30

n = 30 ÷ 5

n = 6

What is the x-intercept
1/2x - 3y = 8

Answers

so first make it into slope intercept form y=mx+b

1/2x-3y=8
subtract 1/2x from both sides
-3y=8-1/2x
multiply both sides by -1
3y=1/2x-8
divide both sides by 3
y=1/6x-8/3

the x intercept is when y=0
so set y to zero
0=1/6x-8/3
add 8/3 to both sides
8/3=1/6x
multiply both sides by 6
16=x

the x intercept is 16
x intercept is when y = 0
so 1/2 x - 0 = 8
solving for x
1/2 x = 8
multiply both sides by 2
x = 16 is the y intercept

T=Pri for t, if i=105, P=700, and r=0.005

Answers

If the numbers are played next to each other (like Pri) then they are multiplied together. So you'd do:
Pri = (700)(0.005)(105) = 700 x 0.005 x 105
= 367.5
