X=1/5

Step-by-step explanation:

7×-2×-10=-9

5×=-9 +10

5×/5=1/5

×=1/5

Answer:

4y + 7

Step-by-step explanation:

Simplify. Use the distribution method, and follow PEMDAS.

PEMDAS is the order of operation. It stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

Distribute 4 to all terms within the parenthesis. In this case, you are multiplying 4 to all the terms:

4(y + 3) = (4 * y) + (4 * 3) = 4y + 12

Next, combine like terms (terms with the same amount of variables);

4y + 12 - 5

4y + (12 - 5)

4y + 7

4y + 7 is your simplified expression.

Answer:

[tex]2x^2+13[/tex]

Step-by-step explanation:

Given

[tex](-5x^2-2x+4)+(8x^2-x-1)-(x+2)(x-5)[/tex]

Required

Simplify

Expand brackets

[tex](-5x^2-2x+4)+(8x^2-x-1)-(x^2-5x+2x-10)[/tex]

[tex](-5x^2-2x+4)+(8x^2-x-1)-(x^2-3x-10)[/tex]

Open all brackets

[tex]-5x^2-2x+4+8x^2-x-1-x^2+3x+10[/tex]

Collect Like Terms

[tex]-5x^2+8x^2-x^2-2x-x+3x+4-1+10[/tex]

[tex]2x^2+13[/tex]

Hence, the polynomial simplifies to [tex]2x^2+13[/tex] and it has a degree of 2

Answer:

Yes

No

Step-by-step explanation:

9-12-15 is just a dilation of a 3-4-5, which is right.

6-8-10 is also a dilation of 3-4-5.

However, 2-4-6 is not a triangle. In fact, it's just a line segment, because 2+4=6

Given:

An angle θ on the unit circle has a sine of [tex]\dfrac{1}{4}[/tex].

To find:

The value of cosθ.

Solution:

We have,

[tex]\sin \theta=\dfrac{1}{4}[/tex]

Since sinθ is positive, therefore, θ lies in first or second quadrant.

We know that,

[tex]\sin^2 \theta +\cos^2 \theta =1[/tex]

[tex](\dfrac{1}{4})^2+\cos^2 \theta =1[/tex]

[tex]\dfrac{1}{16}+\cos^2 \theta =1[/tex]

[tex]\cos^2 \theta =1-\dfrac{1}{16}[/tex]

Taking square root on both sides.

[tex]\cos \theta =\pm \sqrt{\dfrac{16-1}{16}}[/tex]

[tex]\cos \theta =\pm \dfrac{\sqrt{15}}{4}[/tex]

Therefore, the value of cosθ is either [tex]\dfrac{\sqrt{15}}{4}[/tex] or [tex]-\dfrac{\sqrt{15}}{4}[/tex].

80

Step-by-step explanation:

From 1-10 You can see the numbers going from 0-8 on the left side except you repeat the number 4 twice then proceed. Then on the right side you do it backwards but instead you use the 2 times tables and you’re going to want to work your way from bottom to top and then when you reach to 0 which is the number 10 you repeat the 2 times tables again.

Answer:

$56,097

Step-by-step explanation:

First, we have to figure out how much his raise was, so we can convert 3.5% directly to a decimal:

3.5% = 0.035

Then we find

3.5% of 54,200 = 0.035 x 54,200 = 1,897

1,897 + 54,200 = 56,097

So, Mills new salary is $56,097

hope this helps:)

Step-by-step explanation:

Answer:

Mean:(137.2)

Median:(139.5)

Step-by-step explanation:

Mean = (125+136+150+119+143) divide by six(6)

= 823/6 = approx 137.2

Median = for the median, you will arrange the numbers in other. from smaller to the bigger number.

119,125,136,143,150, 150. so 136 & 143 is the middle number.

so you will add the middle number and divide by 2.

that is 136+143/2 = 139.5.

Answer:

The equation will be y=25x+50

Step-by-step explanation:

This is because 50 is only being charged once and is the constant.

They are charging $25 per day thus that is the slope.

Step-by-step explanation:

formula for area is

pi times radius times radius

if the radius is 6,

do 6 times 6=36

36 times 3.14=113.04

Answer:

78

Step-by-step explanation:

102+x=180

x=180-102

x=78

well u can transfer the -5 in denominator to the right hand side

so x=1.2*(-5)

x=-6.0
