What is the linear equation that has slope of 5 and pass through the point (-1, -3)?

1 answer:

4 0

What you would do is that you would use the y=mx+b linear equation
m=5
x=-1
y=-3
b=?
hence, you must solve b to have the equation

-3=(5)(-1)+b
-3=-5+b
-3+5=b
2=b
therefore the equation is
y=5x+2

for standard form you just move everything to equal 0 because there is no fraction next to the x
thus

-5x+y-2=0

What is the value of the following expression?2 x [(12 + 2) x 5] + 32 divided by 2 number on top right 3

a_sh-v [17]

The value of the expression is $141.5$

Explanation:

The expression is $2 \times[(12+2) \times 5]+\frac{3}{2}$

The value of the expression can be determined using the rule PEMDAS.

According to the PEMDAS rule, first we need to perform the operation which is within the parenthesis.

Thus, the expression becomes,

$2 \times(14 \times 5)+\frac{3}{2}$

Multiplying the values within parenthesis, we have,

$2 \times70+\frac{3}{2}$

Using PEMDAS, we need to multiply the numbers.

$140+\frac{3}{2}$

Again using PEMDAS rule, divide the number,

$140+1.5$

Finally, using PEMDAS, let us add the values, we have,

$141.5$

Thus, the value of the expression is $141.5$

Mrs. Mitchell decided to grade her projects by giving each student 50 points if they turned in a project and then an additional

photoshop1234 [79]

Let $c$ be the amount of parts the student answered correctly. Suppose that $s(c)$ is a function between $c$ and the score of a student's project. As the student initially receives a fixed $50$ points for turning the project in and $5$ points for each correct part, the function is initially:

$s(c) = 5c+50$

When the students receive $7$ points for each correct part, the coefficient of $c$ changes, as the amount of points received per correct answer increases. Thus:

$s(c) = 7c+50$ .

I need help with this math question

Percent means per one hundred so we can say that:

p/100≈(28)/(28+81+45+63+35) guessing with my old eyes :)

p/100≈28/252

p≈2800/252

p≈11.11%

So rounded to the nearest 5% you'd have:

p≈10%
