Harshpreet is at Bowl 360 and is walking towards John
Adams High School. What can be a possible location that is
above his path?

Answer:

a)  [tex]y=-5x+70[/tex]

Step-by-step explanation:

Choose points on the line:  (0, 70) and (4, 50)

Let [tex](x_1,y_1)[/tex] = (0, 70)

Let [tex](x_2,y_2)[/tex] = (4, 50)

Use the slope formula to find slope: [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\implies m=\dfrac{50-70}{4-0}=-5[/tex]

Use point-slope form of linear equation to find equation:

[tex]\implies y-y_1=m(x-x_1)[/tex]

[tex]\implies y-70=-5(x-0)[/tex]

[tex]\implies y=-5x+70[/tex]

Answer:

A bag of apples cost $3.2 and orange $1.6

Let oranges be o and apples be a

making o the subject

solve them simultaneously

11.2 - 3a = (16-4a)/2

2(11.2 - 3a) = 16 -4a

22.4 -6a = 16 -4a

2a = 6.4

a = 3.2

➜ Therefore a bag of apples cost $3.2

Find the cost of oranges:

o = 11.2 - 3a

o = 11.2 -3(3.2)

o = 1.6

➜ Therefore a bag of oranges cost $1.6

Answer:

29.64

Step-by-step explanation:

First we multiply 0.3 with 22.8.This will give us 6.84 which is the 30% off.Now we add 22.80 and 6.84 and we will get our answer 29.64.

Answer:

$29.64

Step-by-step explanation:

30% = .30

$22.80 x .30 = 6.84

Next, 22.80 + 6.84 = 29.64

The shirt cost 29.64 when it is not on sale.

B

Step-by-step explanation:

You see that the arrow is pointing up the scale, therefore we know that x is not less than 0

we also see that the dot on the 0 is not filled in therefore we know that x is not equal to 0.

Step-by-step explanation:

There are no right angles among interior angles of a regular pentagon.

Answer:

Straight line graph with positive gradient (slope)

y-intercept: (0, -3)

x-intercept: (12, 0)

Step-by-step explanation:

[tex]y=\dfrac14x-3[/tex]  is a linear function

The line intercepts the y-axis when x = 0:

[tex]y=\dfrac14(0)-3=-3[/tex]

Therefore, the y-intercept is (0, -3)

The line intercepts the x-axis when y = 0:

[tex]\implies \dfrac14x-3=0\\\\\implies \dfrac14x=3\\\\\implies x=12[/tex]

Therefore, the x-intercept is (12, 0)

Step-by-step explanation:

Here,

The vertex of parabola is (4,-7)

Suppose that the equation of parabola is a(x-4)²-b

Now,

[tex]y=a(x-4)^{2} -b\\\\a=\frac{1}{-7-(-5)*2}\\\\a=\frac{1}{-7+5*2} \\\\a=-\frac{1}{4} \\[/tex]

Replacing value of a.

Step-by-step explanation:

I guess you need help because you don't know what logarithm buttons to press on your calculator to deal with this here.

true, normal calculators support only log(x) (= log10(x)) and ln(x) (= loge(x)).

did you not learn in class how the different logarithms are related with each other ?

loga(b) = logc(b)/logc(a)

that is all that is to it.

so, we can easily convert any crazy logarithm to a log10 or ln form.

in our case here, let's use log (log10) :

log17(2) = log10(2)/log10(17) = 0.244650542... ≈ 0.24

that way we could easily calculate it on our calculators.

Answer:

31.25 seconds

Step-by-step explanation:

Examine division

11.6 + 24.4 = 36 m < 50m

and 36 + 37.2 - 73.2m > 50m

50 - 36 = 14m

14 * 23.25/37.2 = 8.75 seconds

7.25 + 15.25 + 8.75 = 31.25 seconds

so it would take him 31.25 seconds to swim 50 meters.

Answer:

D. (3,1)

Step-by-step explanation:

To solve a pair of equations using substitution, first solve one of the equations for one of the variables. Then substitute the result for that variable in the other equation.

[tex]x-2y=1,x+4y=7[/tex]

Choose one of the equations and solve it for x by isolating x on the left hand side of the equal sign.

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

Add 2y to both sides of the equation

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

Substitute 2y+1 for x in the other equation, x+4y=7.

[tex]2y+1+4y=7[/tex]

Add 2y to 4y.

[tex]6y+1=7[/tex]

Subtract 1 from both sides of the equation

[tex]6y=6[/tex]

Divide both sides by 6.

[tex]y=1[/tex]

Substitute 1 for y in x=2y+1. Because the resulting equation contains only one variable, you can solve for x directly.

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

Add 1 to 2.

[tex]x=3[/tex]

The system is now solved.

[tex]x=3,y=1[/tex]
