Answer:
The father was twice as old as his son when he (the father) was 62 years old.
Step-by-step explanation:
(Assuming s = current age:)
f = 3(s-15)
f = 4(s-19)
3s-45 = 4s-76
31 = s

Answer:
6. [tex]\pi = \frac{C}{2r}[/tex]
7. Translation
Step-by-step explanation:
6: To solve for π means to isolate it on one side.
Step 1: Divide both sides by 2r.
[tex]\frac{C}{2r} = \frac{2\pi r}{2r}[/tex] [tex]\pi = \frac{C}{2r}[/tex]Therefore, π = circumference over twice the radius, or circumference over diameter.
7: #7 is a translation because each point is moving vertically 3 units and horizontally 1 unit (3 units up and 1 unit to the right). If it were a reflection, we'd be able to spot a line of reflection, but there isn't any here. Also, if it were a rotation, the triangle would change the way its angled, and it'd be in a different quadrant
Therefore, this is a translation.

Answer:
A) Dilated 150% then reflected across the x-axis
Step-by-step explanation:
By counting the squares of shape A, you can see that 2 squares = 100% and 1 square = 50%. You can then count 2 squares into shape B (because that is your starting point) and then count the remaining squares, which is 3. 3 squares is equal to 150% so we know there is a 150% dilation.
We can then also see shape A has been reflected across the x-axis to give shape B.

Rewrite the quadratic function from standard form to vertex form.
f(x)x^2+6x-5
Answer:
[tex]y = {(x + 3)}^{2} - 14[/tex]
Step-by-step explanation:
The original equation
[tex] f(x) = {x }^{2} + 6x - 5[/tex]
vertex form
[tex]y = a {(x - h)}^{2} + k \\ where \: (h. \: k) \: is \: the \: vertex[/tex]
solve for the x coordinate of the vertex, h
[tex]x = h = - \frac{b}{2a} = - \frac{6}{2(1)} = - \frac{6}{2} = - 3 \\ x = h = - 3[/tex]
substitute -3 back into the original equation to solve for y
[tex]y = { (- 3)}^{2} + 6( - 3) - 5 \\ y = 9 - 18 - 5 \\ y = 4 - 18 \\ y = k = - 14 [/tex]
substitute h and k values into the vertex form
a = 1 So we can omit it
[tex]y = {(x - ( - 3)}^{2} - 14 \\ y = {(x + 3)}^{2} - 14[/tex]
y=−1/2x+3 please guys help
Answer:
-1/2? i dunno
Step-by-step explanation:
Answer:
[tex]-1/2[/tex]
Step-by-step explanation:
[tex]-1/2[/tex] is the answer because [tex]-1/2[/tex] is the gradient of the line in the slope. 3 is the y inter. Which is where the line goes over the y-axis.

The image is an example of which types of symmetry?
Answer:
C
Reason :
A square possesses reflection symmetry, with four reflection sections, two on the side midpoints and two via opposing corners. There are four points in a full 360° movement when the square appears precisely the same. As a result, a square possesses order 4 rotational symmetry about its center of rotation. As a result, the angle of rotation is 90°.
The image has rotational symmetry as well as reflection symmetry. Then the correct option is C.
What is the axes of symmetry?If a line intersect the shape and the shape look identical on both sides of line, then the line is known as axis of symmetry.
From the graph, we can conclude that the image has rotational symmetry as well as reflection symmetry.
Then the correct option is C.
More about the axes of symmetry link is given below.

A random survey showed that 35 out of 52 people plan to vote for Mr Powell for Mayor. About how many people voted in the election, if 525 voted for Mr Powell
Answer:
780
Step-by-step explanation:
35 out of 52 people voted. You’d have to divide the total votes, 525 by the people that voted, so 35 which would equal 15.
Then, multiply 15 by the total of people that didn’t vote, 52, which would equal 780.
Answer:
780
Step-by-step explanation:

Finn is walking on a treadmill at a constant pace for 30 minutes. She has programmed the treadmill for a 2-mile walk. The display counts backward to show the distance remaining. Enter and graph the equation that gives the distance f(x) left in miles as a function of the number x of minutes she has been walking. Then, find and compete the interpretation of the x- and y-intercepts. The equation is f(x) =
30*2=15miles per min. x*y=d.
Answer:
The equation is
[tex]f(x) = - \frac{2}{30} x + 2[/tex]
Step-by-step explanation:
since the function is
[tex]f(x) = - \frac{2}{30} x + 2[/tex]
The y-intercept is 2 and the x-intercept is 30.
since the treadmill is counting down the slope of the function would be negative. she set the treadmill for 2 minute walk so at 0 minutes she has 2 minutes left. as the treadmill counts down at the 30-minute mark she will have zero minutes left.

Anthony drives 15 km at 40 kph and return at the rate of 60kph , what is the average rate for the entire round trip
9514 1404 393
Answer:
48 kph
Step-by-step explanation:
The distance is immaterial, as long as it is the same at both speeds. The total time for some distance d is ...
t = d/40 +d/60
And the average speed is ...
2d/t = 2d/(d(1/40 +1/60) = 2/(1/40 +1/60) = 2(40)(60)/(40+60) = 4800/100 = 48
The average rate for the round trip is 48 kph.
_____
Additional comment
This value is called the harmonic mean of the two speeds. It is the reciprocal of the average of the reciprocals of the speeds.

Answer:
$513.75
Step-by-step explanation:
Let h represent the number of hours he worked in a week
An auto mechanic earns $498.75 in 35 hours during the week. His pay is $2.50 more per hour on weekends.
Hence, his pay Is represented by equation:
$498.75 + $2.50 × x
If he works 6 hours on the weekend in addition to the 35 hours during the week
$498.75 + $2.50 × 6
= $498.75 + $15
= $513.75
Therefore, he earns $513.75

For what value of x is line f parallel to line g?
Answer:
13
Step-by-step explanation:
So the concept is that co-interior angles add up to 180 in parallel line. This means:
3x + 9 + 9x + 15 = 180
So we solve for x.
12x + 24 = 180 ( What I did was simplifying the equation).
12x + 24 - 24 = 180 - 24
12x / 12= 156 / 12
x = 13
