Answer:

y = 25

Step-by-step explanation:

y = 4x - 7

y = 4(8) - 7

y = 32 - 7

y = 25

The value of y is 25 for y=4x-7 when x is 8.

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

Given equation is y=4x-7

y equal to four times of x minus seven.

We need to find value of y when x is 8

y=4x-7

Put x as 8 in the above equation

Multiply four time of eight and subtract seven from the value

y=4(8)-7

The value we get when four time of eight is thirty two

y=32-7

Thirty two minus seven is twenty five

y=25

Hence the value of y is 25 for y=4x-7 when x is 8.

Answer:

Step-by-step explanation:

To write an equation for a circle, we need to find the center and the radius.  We need to find the distance between the two endpoints to find the radius.  To do that, use the distance formula:

d = √(2 - 5)² + (1 + 3)²

√(-3)² + (4)²

√9 + 16 = √25 = 5

If the diameter is 5, the radius is 2.5

Now we need to find the center/midpoint.  Use the midpoint formula:

(5 + 2)/2, (-3 + 1)/2

7/2, -2/2

(3.5, -1)

Now that we have the center and the radius, we can make our equation.  Remember that the equation of a circle is: (x - x of center)² + (y - y of center) = radius²

(x - 3.5)² + (y + 1)² = 6.25

Answer:

125x^3 * y^3 * z^3

Step-by-step explanation:

5^3 = 125

x * x * x = x^3

y * y * y = y^3

z * z * z = z^3

The volume of a cube with an edge has length 5xyz units is 125x³y³z³ cubic units.

The volume of a cube is defined as the total number of cubic units occupied by the cube completely. A cube is a three-dimensional solid figure, having 6 square faces. Volume is nothing but the total space occupied by an object.

Given that, edge of a cube is 5xyz.

We know that, the volume of a cube is a³, where a is edge of cube

Now, volume of a cube

= (5xyz)³

= 125x³y³z³

Therefore, the volume of a cube with an edge has length 5xyz units is 125x³y³z³ cubic units.

Answer:

a. 62

Step-by-step explanation:

use the Bodmas method

=3×9-5+20×2

=62

The value of the expression {[3 x (3+6) - 5] + 20 x 2 will be 62. so option A is correct.

We can simply replace those variables with the value you know of them and then operate on those values to get a final value. This is the result of that expression at those values of the considered variables.

So, use the Bodmas method

=[3 × 9 - 5 ]+ 20 × 2

= [27 -5] + 40

= 22 + 40

=62

Therefore,  the value of the expression {[3 x (3+6) - 5] + 20 x 2 will be 62. so option A is correct.

Answer:

y = -3/4x + 14

Step-by-step explanation:

The slope of a perpendicular line is the opposite reciprocal of the original line.

4/3x -> -3/4x

Now we need to find the y-intercept and we can do that by using the slope intercept form expression [ y = mx + b ].

11 = -3/4(4) + b

11 = -3 + b

14 = b

Put everything we know and solved for back into the expression.

y = -3/4x + 14

It is important that the compass is opened to the length of the segment to be copied, when copying a line segment

The steps to copy a line segment are;

Step 1: Mark a point P that will be one endpoint of the new line segment

Step 2: Set the compass point on the point T of the line segment to be copied

Step 3: The compass width is adjusted to the point V, such that the compass extends the length of the line TV to be copied

Step 4: The compass point is placed at point P with the same width TV from the previous step and draw an arc close to the desired location of the second endpoint

Step 5: A point N is selected on the arc drawn in the previous step as the second endpoint of the line

Step 6: Join points P and N with a line using a straight edge to complete the copied line

Answer:

  123°

Step-by-step explanation:

Each of the parts of the trisected angle is equal to the others.

  ∠PQT = ∠TQS

  7x +6 = -2x +8y -13

  9x -8y +19 = 0 . . . . . . subtract the right-side expression

  ∠TQS = ∠RQS

  -2x +8y -13 = 5x +2y

  7x -6y +13 = 0 . . . . . . subtract the left-side expression

__

These equations can be solved by any of your favorite methods to give ...

  (x, y) = (5, 8)

Then the angle measures are ...

  ∠PQT = 7x +6 = 7(5) +6 = 41

  ∠TQS = -2x +8y -13 = -2(5) +8(8) -13 = 64 -23 = 41

  ∠RQS = 5x +2y = 5(5) +2(8) = 41

The measure of angle PQR is 3·41° = 123°.

_____

Additional comment

Using Cramer's rule, the solution is ...

  x = (-8(13) -(-6)(19))/(9(-6) -7(-8)) = 10/2 = 5

  y = (19(7) -13(9))/2 = 16/2 = 8

I prefer a method like this, or the graphical solution, when the numbers don't lend themselves to substitution or elimination.

__

Obviously, once we have found angle PQT, we can simply multiply it by 3 to find angle PQR. We chose to compute the values of the other angles as a check on our math.

Answer:

-1 = -5

0 = -1

2 =  5

Step-by-step explanation:

In order to do this you need to follow these five (5) steps:

1) Know what each of the variables mean in an equation of a line. The equation of a line is y = mx + b where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept. (Remember that the slope is the steepness  of a line and the y-intercept is the point where the line intersects  the y-axis. The x- and y-coordinates are values of the points on the line of y = 3x - 1.)

2) Identify the m (slope) and the b (y-intercept). The slope is 3, which can also be written as 3/1. The y-intercept is -1. (Remember that subtraction of 1 is the SAME thing as adding -1!) Since the y-intercept is a point it will be plotted at (0, -1).

3) Plot the y-intercept first. Start at the origin (intersection of the x- and y-axes) since the x coordinate is 0. Then move DOWN 1 unit since the y-coordinate is negative.

4) Use the m (slope) to plot at least three new points. The slope can also be represented as "rise/run" or the amount of units that you move UP or DOWN (vertically), then LEFT or RIGHT (horizontally). (Remember: if the numerator is positive (move UP); numerator is negative (move DOWN); denominator is POSITIVE (move RIGHT); denominator is NEGATIVE (move LEFT)). Since our slope is 3/1, and both the numerator and denominator are POSITIVE, that means we will be "rising" (moving UP) 3 units and "running" (moving RIGHT) 1 unit.

Start at the y-intercept  of (0, -1) and move up 3 units and to the right 1 unit. You should be at (1, 2). Plot a point here. Then do it again. You should now be at (2, 5). Plot another point. Now, do it one more time. You should now be at (3, 8). Plot your last point. (If you wish to continue plotting additional points, feel free to do so.)

Step-by-step explanation: so basically you know a complementary angle is 2 angles that make a straight line and a vertical angle crosses which means 2 angles are congruent to each other so I drew a line that bisected the angle by drawing a line that cut through the right angle and i extended a line down from the right angle so now I have a vertical angle and a complementary so from here I labeled each angle <1 <2 <3  If I know angle 3 is 56º then I know 56 plus __ equals 90º I then subtracted 56 from 90 and I got 34 and since I am trying to figure out what angle 1 is I know that angle 1 and 2 are vertical angles therefore I know they are congruent to each other so <1 = 34º

Answer:

  88°

Step-by-step explanation:

If the ratio of the third angle to the sum of the other two is 1 : 2, then the third angle must be 1/(1+2) = 1/3 of the total of angle measures. The third angle is 1/3(180°) = 60°.

If the second angle is 28° less than 60°, then the first angle is ...

  180° -60° -(60-28)° = (60 +28) = 88° . . . . . sum of all angles is 180°

The largest angle is 88°.
