Answer:

89*

Step-by-step explanation:

To find the value of m<1, you need to find the angle right next to it (the third interior angle that isn't labeled).

To find that angle (let's call it x), we have to use an equation.

Since a triangle has a sum of 180* for the interior angles in it, then we can use that to solve for x.

x + 53 + 36 = 180

x + 89 = 180

x = 91

Now to find m<1, we need to use the supplementary angles theorem.

Since m<1 and x are supplementary angles, the sum of those angles would be 180. Using this, we can create an equation.

x + m<1 = 180

91 + m<1 = 180

m<1 = 89

Hence, m<1 is 89*!

Step-by-step explanation:

The hardest part about negative numbers in addition is remembering when to add, rather than subtract. In the last equation, we add the numbers together, because the negative sign cancels out with subtraction. All of the other equations we can follow exactly what it says to do, because there are no minus signs right next to each other.

Answer:

Sum of the first 41 terms = 6724

Step-by-step explanation:

[tex]a_{41} = a_1 + (n - 1 )d = 4 + (41 - 1) \times 8= 4 + 40 \times 8 = 324\\\\S_n = \frac{n}{2}(a_1 + a_n)\\\\s_{41} = \frac{41}{2} (4 + 324) = \frac{41}{2} \times 328 = 41 \times 164 = 6724[/tex]

The sum of the first 41 terms of the following series, to the nearest integer, is 6724.

A series of integers called an arithmetic progression or arithmetic sequence (AP) has a constant difference between the terms.

Given:

An arithmetic sequence,

4, 12,20,...

The common difference d,

d = 20 - 12 = 8.

To find the sum of the first 41 terms:

We will find the 41st term.

Remember that,

aₙ= a₁ + (n-1)d

a₄₁ = 4 + (40)8

    = 324

The sum of the first 41 terms,

Sₙ = (41/2)(4 + 324) = 6724.

Therefore, the sum is 6724.

Step-by-step explanation:

Answer:

x > 67

Step-by-step explanation:

x+3 >70

subtract from each side

x+3-3 > 70 -3

x > 67

Algebra

To solve this, simplify the algebra inequality.

Subtract three from both sides.

x>67

Meaning, x is bigger than 67.

Answer:

mary=10 jack=15

Step-by-step explanation:

After 4 years Mary (x+4), Jack's age (x+5) + 4.

sum of the ages after 4 years :(x+4) + (x+5) +4=33 

Simplifying the equation:

2x+13 = 33 ----->> 2x=20----->>>>x = 10 Mary's age

10 + 5 = 15 which is Jack's age.

Given:

The equation is:

[tex]y=2x+1[/tex]

To find:

The y-coordinates for the ordered pairs (0, _), (-1, _) and (1, _)for this equation.

Solution:

We have,

[tex]y=2x+1[/tex]

For [tex]x=0[/tex],

[tex]y=2(0)+1[/tex]

[tex]y=0+1[/tex]

[tex]y=1[/tex]

For [tex]x=-1[/tex],

[tex]y=2(-1)+1[/tex]

[tex]y=-2+1[/tex]

[tex]y=-1[/tex]

For [tex]x=1[/tex],

[tex]y=2(1)+1[/tex]

[tex]y=2+1[/tex]

[tex]y=3[/tex]

Therefore, the complete ordered pairs are (0,1), (-1, -1) and (1,3). Plot these points on a coordinates plane and connect them by a straight line as shown in the below figure.

Answer:

3x²+8x+5

Step-by-step explanation:

Hi there!

We're given the product of two binomials: (3x+5)(x+1) and we want to express as a trinomial (polynomial with 3 terms)

we can multiply using FOIL; firsts, outers, inners, and lasts

Let's start by multiplying the firsts, which are the first terms in the two binomials, which are (3x+5) and (x+1)

So we'll multiply:

3x*x=3x²

Now we'll multiply the outers, which are the terms on the "outside" in the binomials, which are (3x+5) and (x+1)  (remember to include the sign!)

So we'll multiply:

3x*1=3x

then we'll multiply the inners, which are the terms on the "inside" of the binomials, which are (3x+5) and (x+1)

So we'll multiply:

5*x=5x

finally, we'll multiply the lasts, which are the last terms in the binomials, or (3x+5) and (x+1)

So we'll multiply:

5*1=5

now let's add up everything:

3x²+5x+3x+5

we have some like terms that we can combine

3x²+8x+5

Hope this helps!
