Answer:

y = (-1/4)x + 3

Step-by-step explanation:

to find the perpendicular slope you just find the reciprocal of 4 which is (-1/4)

then find the y-intercept making the line go through (-8, 5) so you do:

y = (-1/4)x + b

5 = (-1/4)(-8) + b

5 = 2 + b

-2  -2

3 = b

Answer:

y = -3x + 30

Step-by-step explanation:

A great website to use for graphing is desmos. You first graph the starting 2 points, turn it into a line connecting it, then make an equation. You should get y = -3x + 5, so when we look for something parallel it should have the same slope. I then put into the graph every equation along with the dot (11,-3) and looked to see which intersected.

Difference indicates subtraction:

The difference of a number and

9

is

(

x

−

)

Twice the difference means

2

(

x

−

)

We know that the answer to this is

2

, so as an equation:

2

(

x

−

)

=

2

If you solve it we would have:

x

←

÷

x

=

+

9

x

=

10

The difference between

10

and

9

is

1

and twice

1

is

2

.

The number is correct.

Note that written as:

The difference of twice a number and

Answer:

14/25

Step-by-step explanation:

If the denominators are the same, subtract the numerators.

21/25-7/25=14/25

14 and 25 do not have any similar factors greater than 1, so we keep it as 14/25.

The value of DA in parallelogram ABCD is 4 inches.

A parallelogram is a quadrilateral (has four sides and four angles) in which opposite sides are equal and parallel to each other.

In parallelogram ABCD:

AB = DC, AD = BC

Hence:

8x - 5 = 3x + 10

5x = 15

x = 3 units

AB = 8(3) - 5 = 19 inches

Let y = AD = BC:

AB + BC + DC + AD = perimeter

19 + 19 + y + y = 46

y = 4 inches

The value of DA in parallelogram ABCD is 4 inches.

Answer:

Yes,

Step-by-step explanation:

Because every "x" Value corresponds to exactly one "y" value.

Yes, the relation is a function.

A relation is a function if it has only One y-value for each x-value.

The given relation is {(3,2), (1, -2), (2, -4), (3, -2)}.

We need to check whether the relation is a function or not.

A function is a binary relation between two sets that associates every element of the first set to exactly one element of the second set.

As we observe the given relation three comma two, one comma minus two, two comma minus four comma three comma minus two.

Yes, the given relation is a function because there is no x value is repeated. Every y value has an unique x value.

Hence, the relation is a function.

Answer:

A; x + 15 = 90

B: x = 75

Step-by-step explanation:

A: complementary angles are angles that add up to 90 degrees. This means that x and 15, the two angles that are complementary, will add up to 90:

x + 15 = 90

B: For B, you just need to solve the equation for x:

1. x + 15 = 90

2. x = 75

Step 1 is the given equation

In step 2, 15 was subtracted from both sides

Answer:

P(X < 3) = 0.9375

Step-by-step explanation:

If the coins tossed by the 3 people all turn up the same, it means that we will have either; HHH or TTT

H is head and T is tail.

Thus; the probability of failure in each trial is;

q = P(HHH) + P(TTT)

P(H) = ½ and P(T) = ½.

Hence;

q = P(HHH) + P(TTT) = (½ × ½ × ½) + (½ × ½ × ½) = ⅛ + ⅛ = ¼ = 0.25

In binomial probability, p = 1 - q

Thus; p = 1 - 0.25 = 0.75

Now to find the probability that fewer than 3 tosses are needed is given by the expression;

P(X < 3) = P(1) + P(2)

Now, because the toss trials are independent, it means that x = 1.

Since x = 1,we can make use of geometric distribution formula which is given by;

P(X = x) = p^(x) • q^(n - x)

Thus;

P(1) = 0.75^(1) × 0.25^(1 - 1)

P(1) = 0.75 × 1

P(1) = 0.75

P(2) = 0.75^(1) × 0.25^(2 - 1)

P(2) = 0.75 × 0.25

P(2) = 0. 75 × 0.25

P(2) = 0.1875

Thus;

P(X < 3) = 0.75 + 0.1875

P(X < 3) = 0.9375

Answer:

x = 1, y = 4

Step-by-step explanation:

Given

(2x + 3) + i(x - 2y) = 5 - 7i

Equate the real parts on both sides

2x + 3 = 5 ( subtract 3 from both sides )

2x = 2 ( divide both sides by 2 )

x = 1

Equate the coefficients of the imaginary terms

x - 2y = - 7 , that is

1 - 2y = - 7 ( subtract 1 from both sides )

- 2y = - 8 ( divide both sides by - 4 )

y = 4
