Which graph represents the solution set of this inequality? -2x + 7 < 23−2x+7<23

kondaur [170]

Answer:

The graph and the number line in the attached figure

Step-by-step explanation:

we have

$-2x+7 < 23$

Solve for x

subtract 7 both sides

$-2x+7-7 < 23-7$

$-2x < 16$

Divide by -2 both sides

Remember

When you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol

$x > -8$

The solution is the interval (-8,∞)

All real numbers greater than -8

In a number line the solution is the shaded area at right of x=-8 (open circle)

Answers:

k = 13The smallest zero or root is x = -10

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

Work Shown:

note: you can write "x^2" to mean "x squared"

f(x) = x^2+3x-10

f(x+5) = (x+5)^2+3(x+5)-10 ... replace every x with x+5

f(x+5) = (x^2+10x+25)+3(x+5)-10

f(x+5) = x^2+10x+25+3x+15-10

f(x+5) = x^2+13x+30

Compare this with x^2+kx+30 and we see that k = 13

Factor and solve the equation below

x^2+13x+30 = 0

(x+10)(x+3) = 0

x+10 = 0 or x+3 = 0

x = -10 or x = -3

The smallest zero is x = -10 as its the left-most value on a number line.

m∠EGC=70°

Step-by-step explanation:

we know that

The measure of the inner angle is the semi-sum of the arcs comprising it and its opposite

m∠EGC=(1/2)[arc EC+arc DF]

Find the value of x

we have

m∠EGC=(7x+7)°

arc EC=50°

arc DF=10x°

substitute and solve for x

(7x+7)°=(1/2)[50°+10x°]

14x+14=50+10x

14x-10x=50-14

4x=36

x=9

Find the measure of angle EGC

m∠EGC=(7x+7)°

substitute the value of x

m∠EGC=(7(9)+7)°=70°.
