Top one (A)

Step-by-step explanation:

X >/ -4 Means that the number is "true" as long as it is -4, or larger in amount.

Answer:

x=6.54138

x=0.458619

Step-by-step explanation:

using the Quadratic Formula where

a = 1, b = -7, and c = 3

x=−b±[tex]\sqrt{b^{2} -4ac}[/tex]/2a

x=−(−7)±√[(−7)2−4(1)(3)]/2(2)

x=7±√(49−12)/2

x=7±√37/2

The discriminant b2−4ac>0

so, there are two real roots.

Cannot Simplify the Radical:

x=[tex]\frac{7+-\\\sqrt{37} }{2}[/tex]

which becomes

x=6.54138

x=0.458619

Answer:

either 19 or 84

Step-by-step explanation:

your question was unclear, it could be 7+12 or 7x12

so for 7+12 ITS 19

and for 7x12 its 84

Answer:

Step-by-step explanation:

The third side is thus, less than 14 + 11 = 25 cm. The side cannot be less than the difference of the two sides. Thus, the third side has to be more than 14 - 11 = 3 cm. So, the length of the third side could be any length greater than 3 cm and less than 25 cm.

Answer:

B. y = | x + 15.5 |

Step-by-step explanation:

The + inside the absolute value equation really means -.

So there is a horizontal shift of 15.5 units left.

Answer:

B. y = | x + 15.5 |

Step-by-step explanation:

Given : y= |x|.

To find : Write an equation for each translation of y= |x|. 15.5 units left .

Solution : We have given that y= |x|.

By the translation rule :if function transformed to  f(x ) →→→ f(x +h) Then graph of the function would shift h units left.

For translation 15.5 unit left we need to add 15.5 in function y= |x|.

y = | x + 15.5 |

Therefore, y = | x + 15.5 |.

Answer:

1/8

Step-by-step explanation:

its says 8 times. That's the only answer with a 8. (I'm not sure tho)

Step-by-step explanation:

the middle one.

S starts at 10 and then subtracts 1 with every step. that means it is going "backwards" from right to left.

T starts at 10 and then subtracts 2 with every step.

in combination the middle graphic follows both.

Answer:

196

Step-by-step explanation:

12, 24, 48, 96, __?

The next term will come by multiplying with number 2

12 *2 = 24,

24*2 = 48,

48*2 = 96,

96*2 = 192,

& The answer will be 196

Answer:

Each time the pervious number is being doubled (multiplied by 2). So the next number would be 96 x 2. So, the next number on the pattern is 192.

Let a = (x1,y1) = (4,6) and b = (x2,y2) = (8,14)

Then, since the formula of the gradient (or Slope), given two points a and b is :

m = (y2 - y1) / (x2-x1) = (14 - 6) / (8 - 4) = 8 / 4 = 2

Then we know that the gradient is m = 2

Good Luck, your the best :)

The bar diagram is attached below. As we can see, the price of a yellow T-shirt is as three times as the price of a blue T-shirt. Hence, we can construct the following equation to determine the ratio between both prices:

[tex]y = r\cdot x[/tex] (1)

Where:

If we know that [tex]x = 8[/tex] and [tex]y = 24[/tex], then the price ratio is:

[tex]r = \frac{y}{x}[/tex]

[tex]r = 3[/tex]

The price of the yellow T-shirt is as three times as the price of the blue T-shirt.

Please mark me brainilest

Malik's average pace was 5.5 minutes per mile.

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

Given; Malik uses an app on his phone to track how far he rides his bike. Yesterday, he biked a new trail in a total of 57.5 minutes, including a 2.5-minute water break. The app notified Malik that he rode 10 miles.

Now, This equation represents the situation.

Now, solve the equation for p;

10p+2.5 = 57.5

Subtract 2.5 from both sides;

10p = 55

Divide both sides by 10

p = 5.5

Therefore, Malik's average pace was 5.5 minutes per mile.

Answer:

Step-by-step explanation:

Note that |-x| = 1, just as |x| = 1.  Removing the absolute value operator in both cases, we get x = 1.   In two dimensions the graph would be a solid dot at  = 1.

Answer:

19 minutes

Step-by-step explanation:

172 - 153

= 19 minutes

Answer:

simple convert to improper to subtract

51/4 turn to a common denominator

so multiply by 3

153/12. 4/12

then just divide 153 by 12 = 12.75* 3 bc 3 costumes are one yard and you get 38.25 costumes or 38 bc you cant have .25 of a costume

The no. of costumes Martin can make is 38.

It is given that 1/3 yards of Ribbon is needed for each costume and [tex]12\frac{3}{4}[/tex] yards of Ribbon is left.

We have to find out the no. of costumes which Martin can make.

What is algebra ?

Algebra is the branch that deals with various symbols and the arithmetic operations and the symbols are called variables.

As per the question ;

Ribbon needed for each costume = 1/3 yards

Ribbon left = [tex]12\frac{3}{4}[/tex] yards

Let's assume no. of costumes Martin can make is x.

The ribbon needed for x costumes will be ;

= [tex]\frac{1}{3}[/tex] × x

= [tex]\frac{x}{3}[/tex] yards

So ;

The no. of costumes will be ;

[tex]\frac{x}{3}[/tex] yards =  [tex]12\frac{3}{4}[/tex] yards

[tex]\frac{x}{3}[/tex] yards = [tex]\frac{51}{4}[/tex] yards

or

4x = 51 × 3

or

x = [tex]\frac{51 * 3}{4}[/tex]

x = [tex]\frac{153}{4}[/tex]

or

x ≈ 38

Thus , the no. of costumes Martin can make is 38.
