Answer 1

Answer:

[tex]m<49/12[/tex]

Step-by-step explanation:

we are given

[tex]y = 3x^2+7x+m[/tex]

To find x-intercept means we have to find zeros

and for finding zeros , we will use quadratic formula

and we have it has two x-intercepts

so, it's discriminant must be greater than 0

so, we will find discriminant

[tex]D = \sqrt{b^2-4ac}[/tex]

now, we can compare with

[tex]y=ax^2+bx+c\\y=3x^2+7x+m[/tex]

and then we can find a , b and c

a = 3, b = 7, c = m

now, we can find D

[tex]D = \sqrt{7^2-4*3*m} \\D=\sqrt{49-12m}[/tex]

It has two x-intercepts

so,

[tex]D = \sqrt{49-12m}>0[/tex]

now, we can solve for m

[tex]49-12m>0\\12m<49\\m<49/12[/tex]

Answers

Answer:

y = 42

Step-by-step explanation:

we can start by getting teh degree of x

62 + 65 = 127

180 - 127 = 53

x = 53

x - y = 11

we know that 53 is x

53 - y = 11

y = 42

Answer: 3400 feet

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

Explanation:

Let

A = (-5, -3)B = (-5, 5)C = (4, 5)D = (4, -3)

be the labels for buildings 1 through 4 in that order.

You could use the distance formula to calculate the distance between each adjacent point, and then add up those values.

A quicker way is to plot all four points on the same xy grid system. Then simply count the spaces between each point to find that

AB = 8BC = 9CD = 8DA = 9

See below for the diagram.

Essentially we have rectangle ABCD with base 9 and height 8

The perimeter of this rectangle is 8+9+8+9 = 34

The problem tells us that 1 unit on the grid represents 100 feet. Since the perimeter was 34, this scales up to 34*100 = 3400 feet that the courier traveled.

This is a little over half a mile since 1 mile = 5280 ft and 3400 ft = 3400/5280 = 0.64 miles approximately.

Fill in the blank to complete the equation below. 99 + 33 = 11(?+3)

Answers

Answer:

? = 9

Step-by-step explanation:

you know 99 + 33 = 132 so you can substitute that: 132 = 11 (? + 3). im going to change ? into x for now: 132 = 11 (x + 3). then distribute the 11 so 132 = 11x + 33. then subtract 33 from both sides (99 = 11x) and divide both side by 11 (x = 9) and you get 9!

1) If OQ and RT are parallel lines and OPS = 779 what is TSU?
A)
73°
B) 770
93
D)
103°

Answers

Correct Question:

If OQ and RT are parallel lines and QPS= 77°, what is TSU?

Answer:

77°

Step-by-step explanation:

Since OQ and RT are parallel to each other, and, <TSU and QPS are corresponding angles lying on the same side of the transversal as well as being positioned in the same corner, therefore:

<TSU is congruent to <QPS.

Thus:

m<TSU = m<QPS

m<TSU = 77° (substitution).

A line passes through (5, –4) and (–1, –4).Use the work below.
m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction. M = StartFraction negative 4 minus (negative 4) Over negative 1 minus 5 EndFraction. M = StartFraction 0 Over negative 6 EndFraction. M = 0.
What can you conclude about this line? Select all that apply.
It is a vertical line.
It is a horizontal line.
The equation is x = –4.
The equation is y = –4.
It is impossible to have m = 0.
