Answer:

See below.

Step-by-step explanation:

The slope of the line is (5-1) / (3 - -3)

= 4/6  = 2/3

Point slope form:

y - y1 = m(x - x1)

Plugging in m = 2/3 and the point (-3,1):-

y - 1 = 2/3(x + 3) (answer)

Slope-intercept form:-

y - 1 = 2/3(x + 3)

y = 2/3x + 2 + 1

y = 2/3x + 3 (answer)

Standard Form:-

y = 2/3x + 3

Multiply through by 3:-

3y = 2x + 9

-2x + 3y = 9  (answer).

Answer:

The dot would be at (4, 6)

Step-by-step explanation:

To graph the line that represents the proportional relationship between the number of slices of pizza purchased and the total cost, divide the change in total cost by the change in the number of slices. In this case, the line passes through the points (4, 6) and (0, 0) with a slope of 1.5.

To graph the line that represents the proportional relationship between the number of slices of pizza purchased and the total cost, we need to identify the slope of the line. The slope represents the rate of change of the total cost with respect to the number of slices. In this case, we can calculate the slope by dividing the change in total cost by the change in the number of slices.

Given that the student bought 4 slices of pizza for $6.00, we can create two points on the line: (4, 6) and (0, 0). The first point represents 4 slices purchased for $6.00, and the second point represents 0 slices purchased for $0.00.

To calculate the slope, we use the formula (change in y)/(change in x), which gives us (6-0)/(4-0), resulting in a slope of 6/4 or 1.5.

Therefore, the line that represents the proportional relationship is a straight line passing through the points (4, 6) and (0, 0) with a slope of 1.5.

Final answer:

The missing factors in the expression 3x³+12x²-9x are obtained by factoring out the common term 3x and then factoring the quadratic expression x²+4x-3. The final factorization is 3x(x+6)(x-1).

Explanation:

To find the missing factors in the expression 3x³+12x²-9x, we first factor out the common term, which is 3x.

So, the expression becomes 3x(x²+4x-3). Next, we need to find two numbers that multiply to -3 and add to 4. These numbers are 6 and -1, so we can further factor the quadratic as 3x(x+6)(x-1). In conclusion, the missing factors of the given expression are x+6 and x-1.

Answer:

100:1

Step-by-step explanation:

To solve this, you must divide the two.

287 / 2.87 = 100

The scale factor of the model is 100:1.

The scale factor between a real building that is 287 feet tall and a model that is 2.87 feet tall is 0.01, or 1:100. This means that each unit on the model corresponds to 100 units on the actual building.

The subject here is regarding scale factor in mathematics. The scale factor is the ratio between the corresponding sides of two similar figures. In this case, the two figures are the actual capital building and its model. To calculate the scale, divide the height of the model by the height of the actual building. So, if an actual building is 287 feet and its model is 2.87 feet, then the scale is given by 2.87 / 287, which is 0.01.

So, the scale of the model to the building is 1:100, because for every one unit on the model, there are 100 units on the actual building. Remember this scale when considering the height and other dimensions of the model or the building.

Answer:

a=4

Step-by-step explanation:

ax − 4 = 2y

We need to get the equation is slope intercept form  y= mx+b.

Lets solve for y

Divide each side by 2

a/2 x - 4/2 = 2y/2

a/2 x -2 = y

or y=a/2 x -2

The slope is a/2 and the y intercept is -2

We want a slope of 2  so a/2 =2

a/2=2

Multiply each side by 2

a/2 * 2 =2*2

Answer:

630.8 for the nearest tenth, and 631 for a whole number.

Step-by-step explanation:

The values of x and y that satisfy the system of equations are x = (1/3 ± i√(19))/1 and y = (±i√(19) + 2)/2.

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

We are given that;

The equations 3x − 1 + 2y = 0 and 3x2 − y2 + 4 = 0

Now,

To find the corresponding values of y, we can plug these values of x into the expression for y that we found earlier:

[tex]y = -1/2(3x - 1). For x = (1/3 + i√(19))/1, we get: y = -1/2(3(1/3 + i√(19))/1 - 1) = -1/2(i√(19) - 2) = (i√(19) + 2)/2. For x = (1/3 - i√(19))/1, we get: y = -1/2(3(1/3 - i√(19))/1 - 1) = -1/2(-i√(19) - 2) = (-i√(19) + 2)/2.[/tex]

These are the values of y that satisfy the system of equations.

Therefore, by quadratic equations the answer will be x = (1/3 ± i√(19))/1 and y = (±i√(19) + 2)/2.

Answer:

7.25

Step-by-step explanation:

4 times 2 is 8 so then add another half and you will get 10 so multiply 2.5 times 2.5

Kellan should use 6.25 cups of water to make a batch of lemonade with 10 scoops of lemonade powder.

To determine how much water should be used, we can set up a proportion using the lemonade powder to water ratio. Since 4 scoops of lemonade powder are used for every 2.5 cups of water, we can write the proportion as:


4 scoops / 2.5 cups = 10 scoops / x cups

To solve for x, we can cross-multiply and divide:


4x = 10 * 2.5

4x = 25

x = 6.25 cups

Therefore, Kellan should use 6.25 cups of water to make a batch of lemonade with 10 scoops of lemonade powder.

Answer: 700

Step-by-step explanation:

The required inequality to calculate the number of additional toys needed to meet the goal of more than 1000 toys and  additional condition is shown in the inequality '300 + x > 1000'.

The goal of the toy drive is to collect more than 1000 toys.

Given that 300 toys have already been collected, we want to find out how many more toys are needed to meet this goal.

To represent this situation, we can set up an inequality where x represents the number of toys still needed.

The inequality would be 300 + x > 1000.

Solving for x, we subtract 300 from both sides to isolate x, which gives us x > 700.

This means that the toy drive needs more than 700 additional toys to meet its goal of donating more than 1000 toys.

Final answer:

The volume of a cylinder with a diameter of 6m and a height of 5m is calculated using the formula V = πr²h. With a radius of 3m, the volume is 141.39m³.

Explanation:

To find the volume of a cylinder with a diameter of 6m and a height of 5m, we first need to calculate the radius of the cylinder. The radius is half of the diameter, so in this case, the radius (r) is 3m. The formula for the volume (V) of a cylinder is V = πr²h, where π (pi) is approximately 3.142, r is the radius, and h is the height of the cylinder.

Using this formula, we get:

V = π × (3m)² × 5m

V = 3.142 × 9m² × 5m

V = 3.142 × 45m³

V = 141.39m³

Therefore, the volume of the cylinder is 141.39 cubic meters.

Answer:

55

Step-by-step explanation:

Given that a circle and inside two chords with same arc length.

We are to find the angle between the two chords.

Given that two arcs subtend angle 125 degrees at the centre.

Let us join the two ends of chords to make the figure as a triangle inside a circle.

The triangle is isosceles as two arcs and hence chords are equal.

By central angle theorem we have the two equal angles as 1/2 (125) = 62.5

Hence we have a triangle with two equal angles 62.5 and another angle 1.

By triangle sum of angles theorem

angle 1+62.5+62.5 = 180

Hence angle A = 180-62.5-62.5 = 55 degrees.

D) feet

A tree 1.5 x 10^3 is 1500 centimeters. That's about 300 inches, which would better be measured in feet.

You can use the fact that normally people use those measurements which are whole numbers or not elongated decimal number mostly and not much big numbers.

The most appropriate unit to measure the length of the tree out of the given options is

Option D:  feet

Normally people use those measurements which are whole numbers mostly and if not, then not too much long after decimal and not much big numbers.

A tree is measured suitably if we use feet. It is because the normal tree height is from few feet to few hundred feet.

If you measure tree height in centimetres, then as you can see in the question, the number before cm unit is quite big to handle by normal people.

If you measure in too big unit like kilometres, then the height would be expressed mostly like 0.some digits.

That's why we choose feet.

Since 1 cm = 0.0328 feet

thus, height of specified tree in feet would be

[tex]\rm 0.0328 \times 1.5 \times 10^{3} = 49.2 \: feet[/tex]

See the number before feet. Its not too big nor too small, and easy to remember and converse. That's why feet is appropriate.
