Solve x2 + 4x − 12 = 0. (1 point) x = 2, x = −6 x = −2, x = −6 x = 3, x = −4 x = −3, x = 4

Answer:

48

Step-by-step explanation:

180- 59- 52 = 69

Therefore,

69 + x + 63 = 180

x = 48

Thenks and mark me brainliest :)

Answer:

the answer is b=48

Step-by-step explanation:

52+y+59=180(angle on a straight line is 180)

collect like terms

y=180-59+52

y=180-111

y= 69

to look for x is equal to

69+x+63=180

collect like terms

x=180-69+63

x=180-132

x=48

so mark the briliest o

Answer:

The area of the rectangle is 4 sq yards.

Step-by-step explanation:

Given that,

The length of the rectangle, [tex]L=\dfrac{2}{13}\ yards[/tex]

The breadth of the rectangle, B = 26 yards

We need to find the area of the rectangle. The formula for the area of a rectangle is given by :

A = LB

Put all the values,

[tex]A=\dfrac{2}{13}\times 26\\\\A=2\times 2\\\\A=4\ yd^2[/tex]

So, the area of the rectangle is 4 sq yards.

Step-by-step explanation:

[tex]\lim_{x \to -3} \sqrt{x^2 - 8}[/tex]

Here we have

[tex]\lim_{x \to -3} f(x)=f(x)[/tex]

Therefore

[tex]\lim_{x \to -3} \sqrt{x^2 - 8} = \lim_{x \to -3} \sqrt{(-3)^2 - 8} = \lim_{x \to -3} \sqrt{9 - 8} = \lim_{x \to -3} \sqrt{1}[/tex]

[tex]\lim_{x \to -3} \sqrt{1}= \lim_{x \to -3} 1 = 1[/tex]

Answer:

answer C

Step-by-step explanation:

Isosceles trapezoids have the property that opposite angles are supplementary.

Here are some needed properties of isosceles trapezoids.

<C and <D are supplementary

<A = <D

<B = <C

<D + <B = 180

<D = 110                         Given

110 + <B = 180               Subtract 110 from both sides..

<B = 70

C

Answer: a = 30

Step-by-step explanation: So, our first step is to subtract twelve from both sides. 3/5a = 18, divide both sides by 3/5, a = 30

Answer:

x  = 73

Step-by-step explanation:

A circle is 360 degrees

4x-5 + x = 360 degrees

5x - 5 = 360 degrees

5x = 365 degrees

Divide by 5

5x/5 = 365/5

x =73

Answer:

y=10

Answer:

x = ±9

Step-by-step explanation:

Isolate 2x^2 by subtracting 65 from both sides:

            2x^2 = 162

Then x^2 = 81, and x = ±9

Answer:

H0 : μ ≤ 600

H1 : μ > 600

B.) NO

C.) YES

Step-by-step explanation:

Here, the null hypothesis is the claim, that mean guest bill is $600 or less ; The alternative will be the opposite of the null which is the counterclaim. This ubstge accountants assertion that guest bill has been increasing

Hence,

H0 : μ ≤ 600

H1 : μ > 600

When the null cannot be rejected, that means there is no sufficient evidence to support the alternative hypothesis, Hence, we stick with the manager's claim

When H0 can be rejected, then there is sufficient evidence to support, the accountant's claim. Thus, we go with the accountant's claim and conclude that the manager is wrong.

Answer:

(x - 11)² + y² = 25

Step-by-step explanation:

First find the center

O = ( (15 +7 / 2), (-3 + 3)/2 )

O = (11, 0)

Then find the radius squared

use the distance formula from the center to either end point of the diameter

r² = (15 - 11)² + (-3 - 0)²

r² = 16 + 9

r² = 25

Formula for circle

(x - h)² + (y - k)² = r²

(h, k) is the center = (11, 0)

The equation is

(x - 11)² + y² = 25

Answer:

$14.23

Step-by-step explanation:

Multiply the original value by 1.035 to get your answer.

Let x be the initial salary

x=13.75

Let y be the new salary

y=x+x(3.5%)

y=13.75+13.75(0.035)

y=13.75+0.48=14.23

New hourly salary=14.23$

[tex] \#TeeNForeveR[/tex]

Step-by-step explanation:

please I'm not sure for the numbers 3 and 2.

for number 10,

2/3x -4 = 3 +5

2/3x = 8+4

2/3x = 12

2x= 12 x 3

2x = 36

x = 18

and for number 4

(y+1)/5 - (y-2)/4 = -1

to clear out the fraction, multiply throughout by 20

after multiplying, we have

4(y+1) -5(y-2)= -20

4y+4-5y+10 =-20

14 -y = -20

-y = -20 + 14

-y = -6

y = 6

Answer:

[tex]\frac{50}{5} - \frac{10}{1/2}[/tex]

Step-by-step explanation:

Given

An expression for [tex]b - a[/tex]

a: Divide 10 in half

This implies that:

[tex]a = \frac{10}{1/2}[/tex]

b: 50​ divided into fifths

This implies that

[tex]b = \frac{50}{5}[/tex]

So, we have:

Answer:

20 times

Step-by-step explanation:

Let's assign the variable "w" for weeks

6 = 3w

Divide by 2 on both sides

2 = w

That means he plays basketball 2 times every week

For 10 weeks we multiply each side by 10

2 x 10 = 10 x w

20 = 10w

He plays basketball 20 times in 10 weeks.
