Please could I have some help with this question? Thanks

Answers

Answer 1

Answer: 270

Step-by-step explanation:

1) Find DE

1 : 6

17 : x

Cross multiply

x = 17 * 6

x = 102

DE = 102

2) Compare the two triangles

1st (ABC)

side = 45

base = 17

2nd (ADE)

side = x

base = 102

[tex]\frac{x}{45} = \frac{102}{17}[/tex]

Cross multiply

17x = 102 x 45

17x = 4590

x = 4590/17

x = 270

AD = 270

Answers

Answer:

-305.296

Step-by-step explanation:

Make y the subject of the equation.

If 4.704=y+310 is the given equation, the value y is -305.3

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

The given equation is 4.704=y+310

Four point seven zero four equal to y plus three hundred ten

We need to solve for y in the given equation.

4.704=y+310

Subtract 310 on both sides

4.704-310=y+310-310

-305.3=y

Hence, y is -305.3 for the equation 4.704=y+310

Answers

The cost per unit of the auto shop function is the slope of the function

87 represents the slope and the cost per tire purchased

The function is given as:

[tex]\mathbf{C(t) = 87t + 32}[/tex]

A linear function is represented as:

[tex]\mathbf{C(t) = mt + b}[/tex]

Where:

m represents the slope or the unit rate.

So, by comparison:

[tex]\mathbf{m = 87}[/tex]

This means that 87 represents the slope and the cost per tire purchased

Answers

Step-by-step explanation:

The number of strawberry ice cream cones the shop sells that Saturday is 9 ice cream.

What is a linear equation?

A linear equation has one or two variables. No variable in a linear equation is raised to a power greater than 1.No variable is used as the denominator of a fraction. A linear equation is defined as an equation that is written in the form of ax+by=c.

calculation:-

An ice cream shop sells ice cream cones with exactly 1 of 3 ice cream flavors in the cone.

let a number of strawberry ice cream this shop sold on satrday=X

number of vanilla ice cream shops sold = X+2

number of Chocolate ice cream shops sold = X+2+11

Total number of icecream sold on Saturday =42

⇒ X+ X+2+ X+2+11 = 42

⇒ 3X + 15 =42

⇒ 3X = 27

⇒X = 27/3

⇒ X = 9

The function g(x) is a transformation of the quadratic parent function, f(x) =
x2. What function is g(x)?

a. g(x) = 1/2x^2
b. g(x) = -2x^2
c. g(x) = 2x^2
d. g(x) = -1/2x^2

Answers

The answer is D) g(x) -1/2x^2

The function g(x) is a transformation (flipped upside down and horizontally stretched) of the quadratic parent function, f(x) = x2. g(x) = -0.5x².

What is flipping upside down?

Flipping upside down, is found by taking the negative of the original function; that is, the rule for this transformation is −f (x).

Since, g(x) is an upside down function of f(x), g(x) = -f(x).

What is stretching a graph?

If we multiply a function by a coefficient, the graph of the function will be stretched.

A function h(x) represents a horizontal compression of f(x) if h(x) = f(cx) and c > 1.

A function h(x) represents a horizontal stretch of f(x) if h(x) = f(cx) and 0 < c < 1.

Since, g(x) is clearly a stretched transformation of f(x), c < 1.

The possible function g(x) = -0.5x².

Which equation represents a line parallel to 3x − 8y = 12?

Answers

Answer: I don’t know the choices, but a line parallel to that equation must have a slope of 3/8 when simplified into slope-intercept form.

Slope-intercept form: y = mx + b

Solving:
3x - 8y = 12
-8y = -3x + 12
y = 3/8x - 1 1/2

The equation that is parallel to 3x − 8y = 12 is y = (3/8)x - 4 so option (A) is correct.

What is a linear function?

A straight line on the coordinate plane is represented by a linear function.

A linear function always has the same and constant slope.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

As per the given equation,

3x − 8y = 12

3x - 12 = 8y

y = (3/8)x - 12/8

By comparing y = mx + c

Slope m = 3/8

The parallel lines have the same slope thus y = (3/8)x - 4 will have the same slope of 3/8 so it will be parallel.

Hence "The equation that is parallel to 3x − 8y = 12 is y = (3/8)x - 4".

find x if the base angles of an isosceles triangle are 47 degrees and 3x+14

Answers

Answer:

Step-by-step explanation:

The value of x is 11.

Given,

The base angles of an isosceles triangle are 47 degrees and 3x+14 degrees.

We need to find x.

What is an isosceles triangle?

An isosceles triangle is a triangle that has two equal sides and two equal angles.

The equal angles are the base angles.

Find x.

We have,

Base angles: 47 degrees and (3x + 14) degrees

Since base angles are equal in an isosceles triangle.

We have,

47 = 3x + 14

47 - 14 = 3x

33 = 3x

x = 33/3 = 11

x = 11

Thus the value of x is 11.
