Answer 1

Answer:

2a-3 and a+4

Step-by-step explanation:

Given the equation

2a²+8a -15 = 3a - 3

We are to find one of its factors

Equate the expression to zero

2a²+8a -15 = 3a - 3

2a²+8a -15 - 3a + 3 = 0

Collect the like terms

2a²+8a - 3a - 15 + 3= 0

2a²+5a - 12= 0

Factorize

2a²+8a-3a - 12= 0

2a(a+4)-3(a+4) = 0

(2a-3)(a+4) = 0

Hence the factors are 2a-3 and a+4

Answers

Answer:

∠ 5 = 122° , ∠ 6 = 58°

Step-by-step explanation:

∠ 5 and 122° are vertically opposite and are congruent , then

∠ 5 = 122°

∠ 5 and ∠ 6 are same- side interior angles and sum to 180°

∠ 5 + ∠ 6 = 180° , that is

122° + ∠ 6 = 180° ( subtract 122° from both sides )

∠ 6 = 58°

Step-by-step explanation:

[tex]13x-\dfrac{1}{2}(4x + 50) = 8x - 1\\\\13x -\dfrac{1}{2}*4x - \dfrac{1}{2}*50 = 8x - 1[/tex]

Answers

Answer:

it would be B, it goes x axis to y axis

Answer: Choice B.   (-3, 3)

Explanation:

Start where the x and y axis meet. This is the origin.

Move to the left 3 units. You'll be directly under point H.

Then move 3 units up to arrive at point H.

Moving to the left 3 means x = -3. Moving up 3 means y = 3.

Together we have the location (x,y) = (-3,3)

You can think of the x,y location as if it was an address on a map or longitude/latitude coordinates.

Timothy

188 pounds

Hamza

Who lost the biggest percentage of his starting weight?



You need to find the percentage of weight loss for each participant.



To find the percentage of weight loss use the formula



Starting weight – Weight after two months x 100

Starting Weight

Answers

Answer:

Jacob lost the biggest percentage of his starting weight.

Jacob: 8%

Timothy: 6.4%

Hamza: 7.5%

Formula: (initial weight - new weight)/initial weight times 100.

Step-by-step explanation:

Jacob: 225 pounds - 207 pounds = 12 pounds

x/100 = 12/225

= 1800/225

= 8%

Timothy: 200 pounds - 188 pounds = 12 pounds

x/100 = 12/188

= 1200/188

= 6.4%

Hamza: 280 pounds - 259 pounds = 21 pounds

x/100 = 21/280

= 2100/280

= 7.5%

Which statement correctly compares the function shown on this graph with
the function y = 4x + 2?

Answers

C sorry if I’m wrong but can I have brainliest

The statement that correctly compares the function shown on the graph with the function y=4x + 2 is 'The function shown on the graph has a smaller rate of change, but a higher starting point.'

What is rate of change of a function?

The rate at which one quantity is changing with respect to another quantity.

For given question;

It is given a function y = 4x + 2

This function represents a line.

We have slope of the line = 4 and y - intercept = 2

We already know that the rate of change of line is given by its slope.

So, the rate of change of given function ;

y = 4x + 2 is 4.

The starting point of function f(x) is 2.

The graph of the line passing through points (-1, 1) and (0, 4)

So using slope formula,

m = (4-1)/ 0-(-1)

m = 3

So, the rate of change of function is 3.

The rate of change of function shown on the graph is smaller than the rate of change of function y = 4x + 2

Thus, the statement that correctly compares the function shown on the graph with the function y=4x + 2 is 'The function shown on the graph has a smaller rate of change, but a higher starting point.'

Hence, The correct answer is option (A)

How many 1/3 cup serving are there in 10/3 cups of dried beans

Answers

sense they gave the same denominator, just multiply, so 1/3 x 10/3 would just be 10.

A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.

The number of 1/3 cups of servings in 10/3 cups of dried beans is 10 cups of servings.

i.e

= 10/3 ÷ 1/3

= 10/3 x 3/1

=  10/3 x 3

= 3

What is a fraction?

A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.

Example: 1/2, 1/3 is a fraction.

We have

Number of dried beans = 10/3 cups

The number of 1/3 cup servings can be found by dividing the total number of cups of dried beans by 1/3.

The number of 1/3 cup servings:

= Number of dried beans cups ÷ 1/3

= 10/3 ÷ 1/3

= 10/3 x 3/1

= 10 cups servings

Thus,

The number of 1/3 cups of servings in 10/3 cups of dried beans is 10 cups of servings.
