(-3, 1) y = 2/5x - 4
x₁ y₁ slope (m) = 2/5x
Since the equation we are looking for is perpendicular to y = 2/5x - 4, we need to find the opposite reciprocal slope. We have to flip the slope upside down and turn it negative.
2/5 ⇒ 5/2 ⇒ -5/2
So far, we have the equation y = -5/2.
Now, we need to find the y intercept by plugging in the given point into point slope form, which is...
y - y₁ = m(x - x₁)
The subscripts in the y and x are just the x and y in (-3,1). They are just placeholders, not exponents.
y - 1 = -5/2(x + 3)
y - 1 = -5/2x - 15/2
+ 1 + 1
------------------------------
y = -5/2x - 13/2 ⇒ final equation
Answer:
47
Step-by-step explanation:
The order of operations is encoded in PEMDAS, or Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction. Because there is only addition and subtraction, we just calculate it from left to right: 42 + 7 - 2 = 49 - 2 = 47.
$48.75 I take $975 * 0.05=$48.75
Answer:
Solution given:
length[a]=3cm
base(b)=7cm
hypotenuse [c]=?
we have
by using Pythagoras law
a²+b²=c²
3²+7²=c²
c=√58=7.61m
<u>the length of the hypotenuse is 7.61m.</u>
