The equation of a line that is parallel to y = 4x - 7 and goes through the point (4,1) is y = 4x - 15.

Given line: y = 4x - 7

Slope of line m₁ = 4

Two lines are parallel lines when the slopes of the lines are the same.

so, m₁ = m₂

m₂ = 4

Now, the equation of a line with slope 4 and passing through the point (4,1) is:

⇒ y - y₁ = m (x - x₁)

⇒ y - 1 = 4(x - 4)

⇒ y - 1 = 4x -16

⇒ y = 4x - 15

Hence the equation of a line that is parallel to y = 4x - 7 and goes through the point (4,1) is y = 4x - 15.

Step-by-step explanation:

Congruent triangles are triangles that have the same size and shape. This means that the corresponding sides are equal and the corresponding angles are equal.

The values of JL, EF and KM are -19units, 29 units and 22 units respectively.

13. From the diagram shown, we have;

JL = JK + KL

where;

JK = x + 2

KL = 4x - 16

JL = 6x - 13

Substitute the expressions

6x - 13 =  x + 2 + 4x - 16

collect like terms

x = -1

JL = 6x - 13 = 6(-1) - 13 = -6 -13 = -19 units

14.  EG = 2x + 13

EF = x + 14

FG = 14

2x + 13 = x + 14 + 14

collect like terms

x = 15

EF = 15 + 14 = 29 units

15. KL = 6

LM = 2x

KM = 3x - 2

3x - 2 = 6 + 2x

collect like terms

x = 8

KM = 3x - 2 = 22 units

Thus, the values of JL, EF and KM are -19units, 29 units and 22 units respectively.

The inverse of multiplication is division. If three groups of four add up to twelve, twelve divided into three equal groups adds up to four in each group. The basic purpose of splitting is to determine how many equal groups have been formed or how many people are in each group when equitably sharing.

To divide two numbers, use the formula Dividend Divisor = Quotient + Remainder. The dividend seems to be the number being divided in this case. The number that divides the number (dividend) into equally equal parts is known as the divisor.:

Answer:

(8,25)

Step-by-step explanation:

Answer:

Step-by-step explanation:

You want to find the number of dimes (x) and the number of quarters (y) in 19 coins that have a total value of $3.55.

Using the given variables, we can write two equations. One is for the number of coins; the other is for their value.

  x + y = 19 . . . . . . . . . . . number of coins

  10x +25y = 355 . . . . . value in cents

It usually works well to solve an equation involving the highest-value coin. That means we want to eliminate the x-variable. Using the first equation, we can write ...

  x = 19 -y

Substituting into the second equation, we get ...

  10(19 -y) +25y = 355

  190 +15y = 355 . . . simplify

  15y = 165 . . . . . . . subtract 190

  y = 11 . . . . . . . . . . divide by 15

  x = 19 -11 = 8

The number of dimes is 8.

The number of quarters is 11.

__

Alternate solution

The average coin value is 355/19 = 18 13/19 cents. The proportion of the highest-value coins is the ratio of the difference between this value and the lowest value, divided by the difference in values.

  proportion of quarters = (18 13/19 -10)/(25 -10) = (8 13/19)/15 = (165/19)/15

  proportion of quarters = 11/19

Multiplying this by the number of coins (19) gives the number of quarters:

  (11/19)×19 = 11 . . . . quarters

You may recognize some similarities to the above solution.

I don't know if that would fit in the box but it wants a rounded form of the answer in a whole number. It was actually 48484.84 and so on, but since we want it in a whole number, I decided to round the .8 since it is above 5 which would round up the answer to 48485. the 4 after the .8 can't do anything besides round down since it isn't higher than 5.

The equation of the parabola that has vertex (0, -3) and also passes through the point (-8,5) is y = -1(x - 0)² - 3.

The vertex form of the equation of a parabola is:

y = a(x-h)² + k

where the vertex = (h, k)

The given vertex, (h, k) = (0, -3)

The line passes through the (-8, 5)

x =  -8,  y  =  5

Substitute x = -8, y = 5, h = 0, y = -3 into the equation to solve for a

y = a(x - h)² + k

 5 = a(-8-0)² + (-3)

 5 = a(-8)² - 3

-8a = 5+3

-8a = 8

  a = 8/-8

  a = -1

Substitute a = -1, h = 0, k = -3 into y = a(x - h)² + k

y = -1(x - 0)² - 3

On the figure, we have the following highlights

Angle 3 and angle y are corresponding angles.

Corresponding angles are congruent

So, we have

y = Angle 3

From the figure

Angle 3 = 70

So, we have

y = 70

x + 70 = 180

Evaluate the like terms

x = 110

The triangle is an isosceles triangle.

So, we have

y = Angle 2

None of the provided options are irrational. Irrational numbers are those which cannot be expressed as the ratio of two integers. In other words, if represented in decimal form, they would continue indefinitely after the decimal point, such as the value of π. This also means, by definition, they cannot be both irrational and an integer.

They are all real numbers as they can represent a distance along a line (they could all be plotted on a number line or graph, for instance).

Only 0 and 4 out of the provided options are integers (whole numbers). As mentioned above, all integers are rational by definition.

Answer:

28 nickels and 17 dimes

Step-by-step explanation:

A nickel is worth 5 cents and a dime is worth 10 cents

If there are X nickels and Y dimes

Total value = 5X + 10Y cents

$3.10 == 3.10 x 100 = 310 cents

So 5X + 10 Y = 310

Divide both sides by 5 to get

5X/5 + 10Y/5 = 310/5

X + 2Y = 62  (1)

The total number of coins is X + Y and is given to be 45

X + Y = 45    (2)

Subtract Eq(2) from Eq(1) to get

X + 2Y - (X + Y) = 62-45 = 17

X + 2Y - X - Y = 17

Collecting like terms

(X - X) + (2Y - Y) = 17

Y = 17

So number of dimes = 17

To find X, the number of nickels use equation (2)

X + 17 = 45

Subtract 17 from both sides

X + 17 - 17 = 45 - 17

X = 28

So number of nickels = 28

For the given value of angle;

∠A = 62°

The complement of ∠A is; 90 - ∠A

complement = 90 - 62

complement = 28°

Now, for supplementary angle:

For the given: ∠A = 62°

supplementary = 180 - 62

supplementary = 118°

Thus, the complement and supplement are obtained as 28° and 118°.
