Answer:

their average present age should be 40

Step-by-step explanation:

they were 35, 5 yrs ago. just add the 5yrs to 35 yrs old and you will get their present age.

Answer:

Step-by-step explanation:

Average age 5 years ago: 35

Sum of ages 5 years ago: 2(35), or 70

Sum of ages now: 70 + 2(5), or 70 + 10 = 80

Current average: 80/2 = 40

So, their average age is 40!

Answer:

A

Step-by-step explanation:

slope -3

y intercept (0,2)

Option A is correct, y=-3x+2 is the equation of the line that best represents the graph of the line.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The line passing through points (1, -1) and (-2, 8)

m=8+1/-2-1

m=-3

Now let us find the y intercept

8=-3(-2)+b

8=6+b

2=b

y=-3x+2 is the equation of line.

Hence, y=-3x+2 is the equation of the line that best represents the graph of the line.

Answer:

6(7 + 4) = 6(11) = 66

Step-by-step explanation:

Answer: x = -10/3 and 8/3

Add 1 to both sides:

∣3x+1∣=8+1

There are two equations:

3x+1=9  and -(3x+1)=9

Solve the first one:

3x+1=9  

3x=9−1

3x=8

x=8/3

Solve the second one:

-(3x+1)=9

−3x−1=9

−3x=9+1

−3x=10

Answer:

576x + 2y + 6

Step-by-step explanation:

so let's work this out

first as you can see we need to work this out in BODMAS Method, but there are also expression.

First do the brackets

3 x 2 = 6

so it is simplified to

24x X 6 X 4x + 2y + 6

We can multiply 24x to 6, even if it doesn't have the same pro numeral since, when multiplying we don't have to look for pro numeral, but if we are adding or subtracting, we can't add or subtract a number with a number that doesn't have the same pro numeral.

so

24x X 6 = 144x X 4x = 576x

Then it is simplified to

576x + 2y + 6

we can't simplify it anymore, since it doesn't have the same pro numeral.

Answer = 576x + 2y + 6

Answer:

Both 79°.

Step-by-step explanation:

In geometry, when an angle is said to be bisected, it implies that the angle is divided into two equal parts.

Therefore, if an angle that measures 158° is bisected, it is divided into two equal angles. That is:

[tex] \frac{158}{2} = 79 [/tex].

Therefore, the bisecting of an angle of 158° will result into two resulting angles of 79° each.

Words such as more than us know that this problem is subtraction, info from this problem also lets us know that we need to subtract 15/8 - 5/6

To intrept this expression:

15/8 - 5/6

45/24 - 20/24

15/24

You make the fractions, with like denominators, then subtract only the numerators.

Let angle 4 denote the angle adjacent to angle 3 on the right side (so between lines a and b, to the right of line c). Angles 3 and 4 are then supplementary.

Lines a and b are parallel, so angles 1 and 4 are congruent because they are alternating interior angles.

By the transitive property, angles 2 and 4 are also congruent.

Again, transitively, angles 2 and 3 are supplementary.

Let angle 5 denote the angle to the left of angle 2 (between a and b, to the left of d). Angles 5 and 2 are supplementary.

Transitively, angles 5 and 3 are congruent.

These two angles correspond to one another, so lines c and d are parallel.

Answer: mPOQ = 86°

Step-by-step explanation: I took the test yesterday and got it correct, I am reliable

The value of the angle m∠POQ will be the difference between ∠NOQ to m∠NOP thus it will be 86°.

An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.

The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.

As per the given,

∠NOQ = ∠NOP + ∠POQ

123 = 37 + ∠POQ

∠POQ = 123 - 37 = 86°

Hence "The value of the angle m∠POQ will be the difference between ∠NOQ to m∠NOP thus it will be 86°".

Step-by-step explanation:

Hello

According to fithaghores law:

[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]

So

[tex] {5}^{2} + {12}^{2} = 25 + 144 = 169 \\ {c}^{2} = 169 \\ c = \sqrt{169 } = 13[/tex]

Let's continue

Tan A = a/b= 5/12

So A is about 22 or 23 degrees.

You know sum of the triangle angles are 180

So sum 90 +23

Then 180-(90+23)=180-113=67

B is about 67 degrees.

a) probability of getting a red ball

   P=no of favourable of outcomes /total no outcomes

   P(red ball) = 5/8

b) Probability of blue ball

  P(blue ball) = 3/8

c) Odds getting a red ball

   odds in favour of any object = m/n

   m : event to occur

   n  : event will not occur

 Odds(red ball) = 5/3

d)

Odds(blue) = 3/5

This shows that as x approaches -7 and 7, the value of y approaches infinity. As x approaches -7 from the left, y approaches ∞.

The vertical asymptotes of a function is the point where the denominator of the rational function approaches zero.

Given the rational function shown:

[tex]\dfrac{-2x^2+14}{x^2-49}[/tex]

The vertical asymptotes occurs when x^2 - 49 = 0

Add 49 to both sides

x^2-49 + 49 = 49

x^2= 49

x = ±7

This shows that as x approaches -7 and 7, the value of y approaches infinity
