What is the value of 4 x minus 7 when x = 4?
Answer: 9
Step-by-step explanation: Here, we have the expression 4x - 7 and we want to evaluate the expression when x is equal to 4.
To evaluate an expression, we simply plug the value
of the variable into the expression and solve.
So here, since x is equal to 4, we have 4(4) - 7.
4(4) is equal to 16.
So we have 16 - 7 which is equal to 9.
So the value of our expression when x is equal to 4 is 9.
Answer:
9
Step-by-step explanation:
4x - 7 ( x=4)
4 × 4 - 7
16 - 7

Daredevil Danny was cliff jumping. He jumped off a cliff that was 14.2 meters above the surface of the
water. At the end of his jump, Danny was 2.3 meters below the surface of the water.
The following equation describes this situation
14.2 + (-16,5) = -23
What does -16.5 tell us?
Answer:
AnSwEr Is C
Step-by-step explanation:
in khAN
The value -16.5 tells us the displacement between his current position and his initial position.
What is displacement?Displacement is defined as the minimum distance between two points. It is a vector quantity and needs direction with magnitude.
It is given that
Initial position =14.2 m
Final position=-2.3 m
14.2+(16.5)=-2.3
To understand this, we need to first calculate the displacement between his initial and final position
Displacement = Final pposition - Initial position
Displacement= -2.3-14.2
Displacement =-16.5 m
So: -16.5m is the total displacement from the start position (i.e. off the cliff) and current position (beneath the water surface)

Answer:
$2.10
Step-by-step explanation:
5 beads + 5 pendants cost $19.50
beads cost $1.80 per necklace
5 beads cost 5 * $1.80 = $9.00
cost of 5 pendants = $19.50 - $9.00 = $10.50
cost of 1 pendant = $10.50/5 = $2.10
Answer:
$2.10
Step-by-step explanation:
For each necklace, the price of the beads totaled up to $1.80. Since there were 5 necklaces, the total price for all of the beads is $9.
5 × 1.80 = 9
The total cost of all materials is $19.50. Since we are trying to find the cost of the pendants, subtract the cost of the beads by the total price.
19.50 - 9 = 10.50
Since you are trying to find the cost of each pendant, divide the costs of all the pendants by 5. You are dividing by five because there is one pendant for on necklace.
10.5/5 = 2.10
The cost of a single pendant is $2.10.
the pyramid below has a rectangular base and E is directly above A. The volume of the pyramid is 600cm^3. Work out the height of the pyramid, AE
Answer:The volume of the pyramid = (1/3)*area of base *height
= (1/3)*10*24*13 = 1040 cubic units.
The total surface area = area of rectangular base + area of 2 isosceles triangles with a base of 24 units + area of 2 isosceles triangles with a base of 10 units.
Area of rectangular base = 24*10 = 240 sq units.
Using the ruler postulate, find the distance between –9 and 2.
Answer:
11 units
Step-by-step explanation:
According to ruler postulate, if there are two points A with coordinate a
and point B with coordinate b, \
then distance ab is given by subtracting coordinate in any order i.e it can be (a-b) or (b-a) and then take the absolute value value of it.
mathematically it can be represented as
AB = |a-b| or |b-a|
_________________________________________
in the given problem points are -9 and 2
thus distance
distance between –9 and 2 = |-9 -2| = |-11| = 11
absolute value of -11 is 11
alternatively, distance can be calculated as
distance between –9 and 2 = |2 -(-9) | = |2 + 9 | = |-11| = 11
The line segment AB with endpoints A (–3, 6) and B (9, 12) is dilated with a scale factor 2∕3 about the origin. Find the endpoints of the dilated line segment. answers: A) (4, –2), (6, 8) B) (–2, 4), (6, 8) C) (–2, 4), (8, 6) D) (2, 4), (6, 8)
Answer:
B. The endpoint of the dilated line is (-2,4),(6,8)
Step-by-step explanation:
Given
Line segment AB
Endpoints: A(-3,6) and B(9,12)
Scale Factor: 2/3 about the origin
Required
Find the end points of the dilated line
From the question, we understand that the line segment is dilated about the origin;
The keywords about the origin implies that, to get the endpoints of the dilated line, we simply multiply the coordinates of of the original line by the scale factor;
This is shown below;
[tex]For\ A = (-3,6);[/tex]
The new endpoints become
[tex]A' = \frac{2}{3} A[/tex]
[tex]A' = \frac{2}{3} (-3,6)[/tex]
[tex]A' = (\frac{2}{3} * -3, \frac{2}{3} * 6)[/tex]
[tex]A' = (\frac{2* -3}{3}, \frac{2 * 6}{3})[/tex]
[tex]A' = (\frac{-6}{3}, \frac{12}{3})[/tex]
[tex]A' = (-2, 4)[/tex]
[tex]For\ B = (9, 12);[/tex]
The new endpoints become
[tex]B' = \frac{2}{3} B[/tex]
[tex]B' = \frac{2}{3} (9, 12)[/tex]
[tex]B' = (\frac{2}{3} * 9, \frac{2}{3} * 12)[/tex]
[tex]B' = (\frac{2* 9}{3}, \frac{2 * 12}{3})[/tex]
[tex]B' = (\frac{18}{3}, \frac{24}{3})[/tex]
[tex]B' = (6, 8)[/tex]
Hence, the endpoint of the dilated line is (-2,4),(6,8)

William has $7.50 to spend at the pretzel shop. A large pretzel costs $1.25 and a soft drink costs $0.90. He buys one drink and p pretzels. Which inequality can be used to find the number of pretzels William can buy?
1.25p−0.9≤7.5
1.25p+0.9≤7.5
1.25p+0.9≥7.5
1.25+0.9p≤7.5
Answer:
the answer is B
Step-by-step explanation:
the reason is because 1.25 x the amount of pretzels he wants plus his price of his one drink will be less than or equal to the amount of money he has
Answer:
B
Step-by-step explanation:
Cost of p pretzels = 1.25 * p = $ 1.25p
cost of p pretzels and cost of a soft drink should be less than or equal to $7.50
1.25p + 0.90 ≤ 7.50

Triangle XYZ has vertices X(2,4), Y(3,4) and Z(3,8). Suppose you reflect this across the y-axis, then dilate it with a scale factor of 2 with the origin as the center of dilation. What are the coordinates of the resulting triangle X″Y″Z″? answers: A) X″(–4,8), Y″(–6,8), Z″(–6,16) B) X″(2,–4), Y″(3,–4), Z″(3,–8) C) X″(–2,4), Y″(–3,4), Z″(–3,8) D) X″(4,–8), Y″(6,–8), Z″(6,–16)
Answer:
X'' (-4, 8)
Y'' (-6, 8)
Z'' (-6, 16)
Step-by-step explanation:
The rule for reflecting across the y-axis is (x, y) -> (-x, y)
When you dilate by a scale factor of 2 about the origin, multiply each coordinate point by 2.
X (2, 4) -> (-2, 4) -> (-4, 8)
Y (3, 4) -> (-3, 4) -> (-6, 8)
Z ( 3, 8) -> (-3, 8) -> (-6, 16)
Can someone help me out?
Answer:
see explanation
Step-by-step explanation:
15
The x- coordinate of E is the same as the vertex F
The y- coordinate of E is the same as the vertex G
E = (b, c )
The x- coordinate of D is the same as vertex G
The y- coordinate of D is the same as vertex F
D = (a, 0 )
16
The x - axis is an axis of symmetry in the rhombus , thus
D is a reflection of B so D = (0, b )
The y- axis is an axis of symmetry in the rhombus, thus
E is a reflection of C so E = (a, 0 )

In right triangle ABC on hypotenuse AB lies points K and M such that AK=AC, BM=BC. Find m∠MCK.
Answer:
The measure of ∠MCK is 45°
Step-by-step explanation:
The parameters given are;
ΔABC with hypotenuse side AB
Let AB = x
BC = y
AC = z
∴ x² = y² + z²
∠BCM = ∠CMB (Base angles of isosceles triangle ΔBMC)
Similarly, ∠ACK = ∠AKC (Base angles of isosceles triangle ΔKAC)
∴ ∠BCM + ∠CMB + ∠CBM = 180° (Sum of interior angles in a triangle)
Hence, 2 × ∠BCM + ∠CBM = 180°........(1)
Similarly, 2 × ∠ACK + ∠CAK = 180°......(2)
Hence, 2 × ∠BCM + ∠CBM = 2 × ∠ACK + ∠CAK
However, ∠CBM + ∠CAK + 90° = 180° (Sum of angles in right triangle ΔABC)
∴∠CBM + ∠CAK = 180° - 90° = 90°
Adding equations (1) and (2), we have;
2 × ∠BCM + ∠CBM + 2 × ∠ACK + ∠CAK = 180° + 180° = 360°
Which gives;
2 × ∠BCM + 2 × ∠ACK + ∠CBM + ∠CAK = 360°
Where;
∠CBM + ∠CAK = 90°, we have;
2 × ∠BCM + 2 × ∠ACK + 90° = 360°
∴ 2 × ∠BCM + 2 × ∠ACK = 360° - 90° = 270°
∠BCM + ∠ACK = 270°/2 = 135°
∠BCM = ∠CMB
∴ ∠CMB + ∠ACK = 135°
Also, ∠CMB = ∠CMK and ∠ACK = ∠MCK
Hence, ∠CMK + ∠MCK = 135°
However, ∠CMK + ∠MCK + ∠MCK = 180° (Sum of interior angles in a triangle)
Which gives;
∠CMK + ∠MCK + ∠MCK = 135° + ∠MCK = 180°
∴ m∠MCK = 180° - 135° = 45°.
The measure of ∠MCK, m∠MCK = 45°.

REMEMBER... I WILL GIVE U THE BRAINLIEST!!!!!!!
Answer:

Step-by-step explanation:
I believe that you are subtracting times here, so have in mind that if the first number indicates hours, and the second number minutes, and you are asked to subtract more of one quantity (minutes for example) than what you have, you will need to convert some of the hours into minutes.
Recall that 1 hour equals 60 minutes.
in the difference 4:08 minus 1:15, you sre expected to subtract minutes from minutes and hours from hours. Now the number of minutes you need to subtract from 08 is 15 (larger than 08) so we need to convert 1 hour into minutes in the first expression, and then (with enough minutes to deal with), we can subtract:
4:08 is the same as 3:68 where we converted 1 hour to 60 minutes and added those 60 minutes to the existing 8 .
Now the difference can be performed:
3:68 - 1:15 = (3-1):(68-15) = 2:53
