Maths please help xx

Step-by-step explanation:

Hey there!

The points through which the line passed are; (-3,-7) and (12,3).

Note: Use double point formula.

[tex](y - y1) = \frac{y2 - y1}{x2 - x1} (x - x1)[/tex]

Keep all values.

[tex](y + 7) = \frac{3 + 7}{12 + 3} (x + 3)[/tex]

Simplify it.

[tex](y + 7) = \frac{10}{15} (x + 3)[/tex]

[tex](y + 7) = \frac{2}{3} (x + 3)[/tex]

[tex]y + 7 = \frac{2}{3} x + 3 \times \frac{2}{3} [/tex]

[tex]y = \frac{2}{3} x + 2 - 7[/tex]

[tex]y = \frac{2}{3} x - 5[/tex]

Therefore, the required equation is; y = 2/3x - 5.

Hope it helps...

Answer:

510 miles

Step-by-step explanation:

miles to drive on second day = total distance - miles driven on first day

                                                 = 955 - 445

                                                 = 510 miles

Answer:

510 miles!

Step-by-step explanation:

If Jackson already drove 445 miles on the first day, the remaining amount of miles is how much further he will have to drive to reach his destination.

[tex]955-445[/tex]

[tex]=510[/tex]

Jackson will need to drive 510 miles on the second day to reach his destination,

Answer:

Aspect Ratio:13:5

Answer: 52 inches

Step-by-step explanation:

The aspect ration is the ratio between the sides which is 6.5:2.5 or 13:5.

Now we know the shorter side is 20 inches, and our aspect ratio basically means shorter side is 5x and longer side is 13x. well putting 5x=20, we get x=4. So the longer side, 13x, is 52 inches.

Answer:

I think the answer is 9-2x/x+1

=================================================

Explanation:

For these type of problems, it helps to do a grid so you can line up the digits.

Check out the diagram below to see what I mean.

The 3 from "3x1" means we have 3 in the units digit

The first "1" from "1x0.1" means we have 1 in the tenths digit

The 4 in 4x0.001 means we have a 4 in the thousandths digit

There's a 0 in the hundredths digit as just a gap or placeholder so to speak. We can think of it as 0x0.01

Answer:

0.20 seconds

Step-by-step explanation:

Given the function:

For the distance traveled by a pendulum in time [tex]t[/tex]:

[tex]P(t)=-5cos(2\pi t)+5[/tex]

Where [tex]t[/tex] is in radians.

Also, given that [tex]P(t)=3.5\ cm[/tex]

To find:

The time [tex]t[/tex] = ? to the nearest hundredth.

Solution:

Putting the values as per given statements, it can be observed that:

[tex]3.5=-5cos(2\pi t)+5\\\Rightarrow -1.5=-5cos(2\pi t)\\\Rightarrow 0.3=cos(2\pi t)[/tex]

Taking the inverse:

[tex]cos^{-1}(0.3) = 2\pi t[/tex]

[tex]\Rightarrow 2\pi t=72.54^\circ[/tex]

We know that [tex]2\pi\ radians = 360^\circ[/tex]

Putting the value above:

[tex]\Rightarrow 360t=72.54^\circ\\\Rightarrow t = \dfrac{72.54}{360}\\\Rightarrow t =\bold{0.20}\ seconds[/tex]

So, after 0.20 seconds, the pendulum reaches 3.5 cm from the place it was released.

34+(8)(2)

−4

=66

Answer:

1

Step-by-step explanation

Since you are given two points you can calculate the slope by use the formula Y1-Y2/X1-X2.

In this case:

Y1 = 5

Y2 = 7

X1 = 7

X2 = 9

(5-7)/(7-9) = -2/-2 = 1

Answer:

100 in^2

Step-by-step explanation:

(15/21)^2 x 196 = 100

Answer:

=> x = 192

Step-by-step explanation:

[tex] \frac{144}{x} = \frac{x}{256} [/tex]

therefore we cross multiply x • x and 144 multiply 256

[tex] {x}^{2} = 144 \times 256[/tex]

multiply 144 by 256

[tex] {x}^{2} = 36864[/tex]

take √ 36864

[tex]x = 192[/tex]

Answer:

x = -2

Step-by-step explanation:

2x + 4 = 0

2x= -4

x=-2

Equation: [tex]2x+4=0[/tex]

Subtract 4 from both sides:

[tex]2x+4-4=0-4\\2x=-4[/tex]

Divide both sides by 2:

[tex]\frac{2x}{2}=\frac{-4}{2}[/tex]

Simplify:

[tex]\frac{-4}{2}=-2\\x=-2[/tex]

Therefore, your answer would be x = -2.

Answer:

Combined means to add so you are going to add anything over 1 because it says longer than 1

1 1/4  has 2 marks so you add 1 1/4 + 1 1/4 =

they have like denominators so you can add them together

1 + 1 = 2 and 1/4 + 1/4 = 2/4 which can be reduced to 1/2

Answer:

A. Product quality is not affected by size.

Step-by-step explanation:

This statement is true because the quality of a product is not a measure of its size, which is a quantifiable factor. This means that we can have a very small-sized product which has very good quality. Size also depends on the product being manufactured. Quality is rather measured by how good the materials used in the production are.

If inferior materials are used in the production, then the product, no matter how small or big they are, would lack quality. To obtain a good and accurate measurement, a lot of time and energy should be invested.

Answer:

The basic formula is y=bx y = b x . This can be where 25 is equal to 5 times 5, or 1000 is equal to ten times ten times ten, and can then be written as 52 5 2 or 103 10 3 . The number that is repeated is called the base, and the number of times it repeats is called the exponent, power, or degree.

Answer:

The equation of a line that passes through the point (-5,7) and has a slope of -2/5 would be y = -2/5x + 5

Step-by-step explanation:

In the math term y = mx + b, "m" represents slope. So you can just substitute it for -2/5. "b" represents the y-intercept. 5 is the only number that works, so you just substitute "b" for 5.
