f(X)=3x+7

f(10)=3(10) +7

f(10)=30 +7

f(10)=37

Answer:

f(10)=37

Step-by-step explanation:

f(x)=3x+7

(for f(10) we sub 10 for x)

f(10)=3×10+7

=30+7

=37

Step-by-step explanation: the answer is x = 1/2

The value of x is 27 units.

It is required to find the value of x.

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle and corner whether constituting a projecting part or a partially enclosed space.

Given:

If m∠1 equals (4x + 2) and m∠3 equals (5x − 25),

According to given question we have,

m∠1 =m∠3

(4x + 2)=(5x − 25)

compare the like terms and simplify we get,

2+25=5x-4x

27=x

Therefore, the value of x is 27 units.

Step-by-step explanation:

Understanding stem-and-leaf plots

A stem and leaf plot is designed in a way to group the numbers by their values before the ones place;

i.e. 92, 100, 101, 103, 113

Charted as

9 | 2

10 | 0 1 3

11 | 3

So, with that in mind we know 78 is grouped under the 7 | # # #

stem and has the leaf of 8 which is displayed by # | # # # 8

SO,

TO SOLVE:

Count the 8's under the 7 | # # # # group

We can see that there are 4 8's under that section, and assuming that each number is representative of one students score, we can conclude that 4 students scored 78

Answer:

x = 0.71 and so on

Step-by-step explanation:

Answer:

The slope is m, and the y-intercept is b.

Step-by-step explanation:

What ever is attached to the x is the slope. The y-intercept is the b because it has a 0 on the x axis and a number on the y axis.

The undefined term should be considered when A line extends both directs between point X and point Y.

In terms of geometry, the undefined term should represent the main object where the rest of the objects should be considered as the line, point, and the plane.

So when there is the line extension that lies between point x and point Y so it should be an undefined term.

18 T-shirts

Step-by-step explanation:

1gram = 1000milligrams

1gram × 156000milligrams ÷ 1000milligrams

The milligrams unit cancel out each other thus grams remains as the main unit.

=156grams

1 T-shirt = 156grams

1 T-shirt × 2808grams ÷156grams

The grams unit cancel out each other thus T-shirt remains as the main unit.

cakes is 15

2.50(114)+15y....≥510

(285+15y≥510)-285

y≥15

9514 1404 393

Answer:

  4.  2.5x +15y > 510

  5.  y > 10

Step-by-step explanation:

4. The revenue from each of x cupcakes is 2.50, so the total revenue from cupcake sales is 2.50x.

The revenue from each of y cakes is 15.00, so the total revenue from cake sales is 15.00y.

The total revenue from sales of cupcakes and cakes is more than 510, so we can write the inequality ...

  2.5x +15y > 510 . . . . possible combinations of cakes and cupcakes

__

5. For x=144 the constraint on y is ...

  2.5(144) +15y > 510

  360 +15y > 510

  15y > 150

  y > 10 . . . . possible number of cakes sold

Answer:

Because if you multiply 6 three times, it comes out to be 18.

So basically, 6 x 3 = 18

To be sure, 18 ÷ 6 = 3

So, 18:3 = 6:1

18:3 and 6:1 are equivalent ratios because those are equivalent fractions.

Suppose that we've got two quantities with measurements as 'a' and 'b'

Then, their ratio(ratio of a to b) a:b

or   [tex]\dfrac{a}{b}[/tex]

We usually cancel out the common factors from both the numerator and the denominator of the fraction we obtained. Numerator is the upper quantity in the fraction and denominator is the lower quantity in the fraction).

Suppose that we've got a = 6, and b= 4, then:

[tex]a:b = 6:2 = \dfrac{6}{2} = \dfrac{2 \times 3}{2 \times 1} = \dfrac{3}{1} = 3\\or\\a : b = 3 : 1 = 3/1 = 3[/tex]

Remember that the ratio should always be taken of quantities with same unit of measurement. Also, ratio is a unitless(no units) quantity.

Explanation;

If we get the factors of the first ratio, we will see that;

18: 6 and 3, and 18 and 1

3: 3 and 1

Hence, if we display the ratios in fractions;

18/3 = 6/1

And then we write them in factors, we will get;

3x6/3x1 = 6/1

Simplifying;

3/3 x 6/1 = 2/1 x 3/1 = 1/6

Therefore, 18:3 and 6:1 are equivalent ratios.

Answer:

[tex]f(d)=\left\{ \begin{matrix} 11 & \text{for} & 0< d\leq 4 \\-3+3.5d & \text{for}& d > 4 \end[/tex]

Step-by-step explanation:

Cost of first 4 kilometers ride = 11 pesos.

So, for the first 4 km, the fair is constant i.e.

for 1 km the fare is 11 pesos,

for 2 km the fair is also 11 pesos,

similarly, for 3 km of 4 km, the fare is 11 pesos.

Hence, for the distance [tex]0\geq d\geq 4[/tex], the fair function,

[tex]f(d)=11\cdots(i)[/tex]

After 4 km, there is an increment of $ 3.50 for each kilometer.

So, the fare function up to 5 kilometers,

[tex]f(d)=11+3.5=14.5[/tex]

So, the fare function up to 6 kilometers, i.e for the distance [tex]5<d\leq6[/tex],

[tex]f(d)=11+2\times3.5=18[/tex]

This can be arranged as the fare function up to 6 km,

[tex]f(d)=11+(6-4)\times3.5=18[/tex]

Similarly, the fare function up to [tex]d[/tex] kilometer [tex](n>4)[/tex],

[tex]f(d)=11+(d-4)\times3.5[/tex]

[tex]\Rightarrrow f(d)=-3+3.5d\cdots(ii)[/tex]

Hence, from equations (i) and (ii),

[tex]f(d)=\left\{ \begin{matrix} 11 & \text{for}\; 0< d \leq 4 \\-3+3.5d & \text{for}\; d > 4 \end[/tex]

Answer:

15 and 1/15

Step-by-step explanation:

Given

Time (t) = 30 minutes

distance (d) = 2 miles

To determine the first constant of proportionality

Let time be directly proportional to distance.

t = kd

Where k is the constant of proportionality

Make k the subject

k = t/d

Substitute values for t and d

k = 30/2

k = 15

To determine the second,

Let distance be directly proportional to time.

d = kt

Make k the subject

k = d/t

Substitute values for d and t

k = 2/30

k = 1/15

Hence, the constant of proportionality are

15 and 1/15
