What would be the x intercept

Mathematics

1 answer:

Nuetrik [128]3 years ago

8 0

Answer: (1, 0) or 1

Step-by-step explanation:

Since it is parallel to y=2x-7 that means it has the same slope but a different y-intercept. Let's use b for the unknown value

6=2(4)+b

6=8+b

6-8=8+b-8

-2=b

Now we know the equation for the line is y=2x-2

Since we are looking for the x-intercept y will be 0 and we can sub that in to solve

$0=2x-2\\0+2=2x-2+2\\2=2x\\\frac{2}{2} =\frac{2x}{2} \\1=x$

The x-intercept is 1

Since x is less than 0 we have to use -2x.

Substitute -3 for x.

f(x) = -2(-3)

f(x) = 6

The two way table shows the number of students that do or do not do chores and for those

statuscvo [17]

Answer:

Step-by-step explanation:

First you would have to add up all of the kids who do do chores, and all of the kids who do mot do chores. 24+8=32 and 27+16=43. It is then asking how many more... so you would subtract 32 from 43 and that would be 11.

Find the total area of the given figure

Dahasolnce [82]

Answer:

$A=996\ in^2$

Step-by-step explanation:

we know that

The total area of the figure is equal to the area of the square plus the area of the triangle

step 1

Find the area of triangle

The area of triangle is equal to

$A=\frac{1}{2}(b)(h)$

where

b is the base of triangle (is the same that the length side of the square)

h is the height of triangle

we have

$h=35\ in$

Applying the Pythagorean Theorem

Find the length side b

$37^2=35^2+(b/2)^2$

$(b/2)^2=37^2-35^2$

$(b/2)^2=144$

$(b/2)=12\\b=24\ in$

Area of triangle

$A=\frac{1}{2}(24)(35)=420\ in^2$

step 2

Find the area of the square

The area of the square is

$A=b^2$

we have

$b=24\ in$

substitute

$A=(24)^2=576\ in^2$

step 3

Find the total area of the figure

Adds the areas

$A=420+576=996\ in^2$

-2,-7,-12 ,.... is an arithmetic sequence Find the sum of its first 20 terms ?

nlexa [21]

Given sequence:

-2,-7,-12 ,..

Unknown;

Find the sum of the first 20 terms = ?

Solution:

The sequence is -2,-7,-12 ,..

To find he sum of n-terms of a sequence, we use the expression below;

Sₙ = $\frac{n}{2} (2a + (n-1)d)$

where n is the number of terms = 20

a is the first term = -2

d is the common difference= -7 - (-)2 = -5

Now input the parameters and solve;

Sₙ = $\frac{20}{2} (2(-2) + (20 - 1) x -5)$

Sₙ = 10(-4 + -5(19)) = 10(-99) = -990

The sum of the first 20 terms of the sequence is -990
