Which ordered pair is a solution to y = 3+x?
A) (-4,-1)
B) (2,-1)
C) (2,-5)

Answers

Answer 1

Answer:

Answer:

The answer is A) (-4,-1)

Step-by-step explanation:

You have to substitute!!! :)

A) (-4,-1):

y = 3 + x

-1 = 3 + -4

-1 = -1

YES

B) (2,-1):

y = 3 + x

-1 = 3 + 2

-1 = 5

C) (2,-5):

y = 3 + x

-5 = 3 + 2

-5 = 5

Answer 2

Answer:

Answer:a

Step-by-step explanation:

If you substitue it in for a, you get 3-1=-4, which satisfies the equation.

Which equation best represents the line that is parallel to 3x -4y=7 and passes through the point (-4,-2)? Select two options.

Answers

Answer:

The equation that best represents the line that is parallel to 3x - 4y = 7 and passes through the point (-4, -2) is y = 3/4x + 1.

Step-by-step explanation:

3x - 4y = 7 and (-4, -2)

First, solve for y in the equation:

3x - 4y = 7

-4y = -3x + 7

4y = 3x - 7

y = 3/4x - 7/4

m = 3/4 (This will be the slope of the parallel line.) and (-4, -2)

Use the point-slope equation to find the equation that will best represent a parallel line:

y − y1 = m(x − x1)

y - -2 = 3/4(x - -4)

y + 2 = 3/4x + 3 (the 4s cancel out)

(3/4 x 4/1 = 3)

y = 3/4x + 1

Hey there I see you need help well I am here to do just that so for this question you do 5^23 - 5^21 = 5^21(5^2 - 1) = 5^21(25 -1)= 5^21(24)
so 5^21(24) is the answer
i hope this helps

For this question you can say:(we factor it out)
5^23 - 5^21 = 5^21(5^2 - 1) = 5^21(25 -1)= 5^21(24)
so 5^21(24) is the answer :))))
i hope this is helpful
have a nice day

Answers

Answer:

1. 64 cm²

2. 240 yard²

3. 85.13 cm²

4. 193.36 m²

Step-by-step explanation:

Ques 1: We are given two rectangle with dimensions,

Length = 12 cm, Width = 4.5 cm and Length = 5 cm, Width = 2 cm.

As, we know, Area of a rectangle = Length × Width

So, we have,

Area of 1st rectangle = 12 × 4.5 = 54 cm²

Area of 2nd rectangle = 5 × 2 = 10 cm²

Thus, the total area of the figure = 54 + 10 = 64 cm²

Ques 2: We are given a triangle and a rectangle with dimensions,

Triangle: Base = 24-12 = 12 yd and Height = 8 yd

As, Area of a triangle = $(1)/(2) (Base * Height)$

i.e. Area of the triangle = $(1)/(2) (12* 8)$

i.e. Area of the triangle = $(1)/(2)* 96$

i.e. Area of the triangle = 48 yard²

Rectangle: Length = 24 yd, Width = 8 yd

As, we know, Area of a rectangle = Length × Width

i.e. Area of a rectangle = 24 × 8 = 192 yard²

So, the total area of the figure = 48 + 192 = 240 yard².

Ques 3: We are given a triangle and a semi-circle with dimensions,

Triangle: Base = 8 cm and Height = 15 cm

As, Area of a triangle = $(1)/(2) (Base * Height)$

i.e. Area of the triangle = $(1)/(2) (8* 15)$

i.e. Area of the triangle = $(1)/(2)* 120$

i.e. Area of the triangle = 60 cm²

Semi-circle: Diameter = 8 cm implies Radius = 4 cm.

So, Area of the semi-circle = $(\pi r^(2))/(2)$

i.e. Area of the semi-circle = $(\pi 4^(2))/(2)$

i.e. Area of the semi-circle = $(16\pi)/(2)$

i.e. Area of the semi-circle = $(50.26)/(2)$

i.e. Area of the semi-circle = 25.13 cm²

Thus, the total area of the figure = 60 + 25.13 = 85.13 cm²

Ques 4: We are given a rectangle and a semi-circle of dimensions,

Rectangle: Length = 15 m, Width = 7 m.

As, we know, Area of a rectangle = Length × Width

i.e. Area of a rectangle = 15 × 7 = 105 m²

Semi-circle: Diameter = 15 m implies Radius = $(15)/(2)$ = 7.5 m

So, Area of the semi-circle = $(\pi r^(2))/(2)$

i.e. Area of the semi-circle = $(\pi (7.5)^(2))/(2)$

i.e. Area of the semi-circle = $(176.72)/(2)$

i.e. Area of the semi-circle = 88.36 m²

Thus, the total area of the figure = 105 + 88.36 = 193.36 m²

What is 1 and 1/2 minus 7/8

Answers

Convert 1 and 1/2 to eights to make it easier to subtract. 1 4/8 add 1 to 4/8
12/8 then subtract that by 7/8 straight across the numerator. That then equals 5/8

You would find a common denominator 8. 1 and1/2 would be converted into 1 and4/8. 1 and 4/8 minus 7/8 equals 5/8
